FIELD OF THE SUBJECT MATTER

The field of the subject matter is broadly a dynamic wireless network and more specifically, an interactive wireless information communication and delivery system is disclosed that includes software, hardware and related methods.

BACKGROUND

Consumers who own and use wireless two-way communication devices, such as smart phones, personal digital assistants or PDAs, hand-held devices, and other two-way communication devices, are constantly looking for new ways to use that device to interact with one's surroundings and/or receive information about their surroundings or specific items in a certain range. In addition, consumers do not want to purchase, rent or carry additional devices other than their primary device mostly based on convenience. It is this desire that has caused the dramatic increase in device applications or software “apps” that allow the user to accomplish additional tasks on a smart phone.
For example, a tourist who wants to tour a museum. The tourist will pay a fee to enter the museum, buy a guidebook and/or rent an electronic device that contains an education program on the artwork in the museum. The tourist then walks around the museum listening to the recording. The tourist must control the recording depending on where he/she is in the museum. The tourist follows a specified path, since the recording is fixed and cannot be changed based on location without rerecording the updated information.
There are conventional systems that utilize the user's smart phone in some way. For example, there are conventional systems that require the wireless-enabled device to scan for WiFi™ transceivers and many wireless-enabled devices are not available in response to the scan mode. In this instance, the wireless-enabled device is not able to detect the presence of transceivers. On the other hand, other smart phones may not be able to “know” or “comprehend” the relative position of nearby transmitters or able to correct WiFi™ protocol.
Another issue with many conventional devices is the requirement of additional hardware by the smart phone user. Solutions such as Active Bat™, for example, may require a special sound receiver and transmitter. Other WiFi™ GPS or global positioning systems solutions such as Sky Hook™ utilize standard WiFi™/GPS hardware which may provide a ten to twenty meter accuracy, and may not be very accurate for a moving or roving user in a large room with other users.
One additional piece of the puzzle is the information that is being accessed. As mentioned with the museum example outlined above, user may access a pre-taped recording organized in accordance with a specific path through the museum. Other conventional systems may require users to press a button or activate a recording at the site of each individual piece of art or interesting item. Obviously, this solution is problematic, because tourists are constantly arriving at or leaving a piece of art, and so, if someone arriving at the piece of art presses the button to activate the site recording, another arriving late will not hear it from the beginning. Some conventional solutions link to web pages.
Many conventional solutions may not track interest expressed in a particular object and/or the time spent in front of that object by each individual observer. Other conventional solutions may not allow the tourist or observer to get targeted information and/or promotional items based on the time spent in front of the artwork. For example, it would be ideal if a system were produced that sent the observer a note about a sale on Monet posters in the gift shop, if the observer spent a lot of time looking at the Monet collection. Current solutions also lack the ability to manage information in diverse formats and to allow users to record interests in specific objects.
Furthermore, there are global positioning systems (GPS) and related software that allow a user or operator to get some information about a particular location. For example, when a driver is operating an automobile with GPS, the system will show the operator what restaurants or gas stations are at the upcoming exits. While the driver may arbitrarily decide to exit and pick the first restaurant, there is no information that can be transmitted to the restaurant as to whether the driver searched for that restaurant or restaurant chain, what that driver ordered when he/she stopped, whether the driver used the drive-thru window or came inside of the restaurant, and other information that may help the restaurant or restaurant chain better market to consumers. There is a need for solutions for pushing out promotions to the prospective consumers based on their previous preferences coupled with their immediate proximity to their desired restaurant or gas station chains.
In a smaller environment, a trade show may have a hundred company booths with booth attendants who are trying to get someone to stop, chat, provide a business card and ideally, purchase what the company is selling. Trade show booths usually put out a fishbowl for business cards using a giveaway item as an enticement for the attendee to stop and talk or provide a business card. One of the new methods of getting information from attendees is for the booth workers to scan the badge of the attendee with a wireless scanner. This process results in a report being communicated to the company of additional information not usually found on a normal business card. Additional information may include what products the attendee is interested in, what journals the attendee reads, what type of business the attendee is in and other specific information provided by the attendee when registering for the tradeshow or provided to the organizing entity earlier.
There is a need for method of tracking attendees from booth to booth, whether they approach a particular booth, determining how long attendees linger at a booth, and whether they visit the booth multiple times and other information that may help the companies involved in the trade show. Consequently, there is a need in the arts for one or more systems that meet the needs and desires of both the consumer and the transmission-controlling entity, such as a museum, trade show, restaurant, sporting venue, retail outlet, theme park, hospital or any other suitable business.
Specifically, there is a need for wireless information communication and delivery systems that provide improved communication between transceivers and wireless-enabled devices based on software applications and between transceivers and wireless-enabled devices provide a wireless network that has transceivers having several modes of operation. For instance, reduced or limited interference mode that allows transceivers to establish communication with localized wireless enabled devices or a distant access mode for communication with distant wireless access points. Other needs may include for enhanced user experience including combining the configurable transceiver with a modified protocol or improved accuracy of the transmission of communication to the user as he/she moves around an environment. Still other needs including utilize the information and experiences of other users to add information and improve accuracy of the information and experience and/or utilize the information transmitted by other users to improve the information related to the distance above, below and around the observer. For example, a need for a novel system that can manage various formats of information, along with including the ability to search through the information system's history by using sophisticated and up-to-date search mechanisms and can provide promotional items or other information to a user based on the user's tracking input.

As mentioned above, there are many advantages of the developed the dynamic and interactive wireless information communication and delivery systems. Other advantages, for instance, may include that the observer may generate reduced noise and/or interference by using his/her smart phone or laptop to search for information on Internet, and companies can deliver content across both traditional “face to face” and mobile application platforms simultaneously.
In one exemplary embodiment as described below, a wireless information communication and delivery system is disclosed that includes one or more wireless-enabled devices, a device location system, a positioning and communication system, and an information repository system. Many of the systems disclosed herein may be used in other contexts, which will be disclosed herein.
FIG. 1 shows a wireless information communication and delivery system 100 includes a wireless-enabled device 110, a device location system includes one or more transceiver 120, peer laptop 125 or combination thereof, a positioning and communication system including one or more reference point or access point 140 and an information repository system 150. FIG. 1 also shows a transceiver 160 that is out of range of the wireless information communication and delivery system. A configurable wireless protocol device is disclosed that includes a multi-modal transceiver that can establish a communication network with a local wireless-enabled device, such as a smart phone or laptop. A wireless network is described that includes one or more configurable wireless protocol device, one or more wireless-enabled device, and one or more wireless access point or a combination thereof. Wireless networks may also comprise other devices or electronics, including computers, laptop computers, hand-held and/or suitable devices.
As used herein, the term “wireless” refers to wireless communication to a device or between multiple devices. Wireless devices may be anchored to a location and/or hardwired to a power system, depending on the needs of the business, venue, event or museum. In one embodiment, wireless devices may be enabled to connect to Internet, but do not need to transfer data to and from Internet in order to communicate within the wireless information communication and delivery system.
As used herein, the term “smart phone” refers to a wireless communication device, that includes, but not is limited to, a transceiver, receiver, or transmitter, dynamic, static or non-transitory memory device(s), one or more computer processor(s) to process received and transmitted signals, for example, to and from the Internet, other wireless devices, and to provide communication within the wireless information communication and delivery system including send, broadcast, and receive information, signal data, location data, RSSI, one or more indications of signal strength to data tags from one or more information repositories, a bus line, an antenna to transmit and receive signals, and power supply such as a rechargeable battery or power storage unit.
FIG. 2 shows an advanced network development diagram 200 that includes a wireless-enabled device 210, a device location system comprising at least one transceiver 220 and its components 225, a positioning and communication system comprising at least one reference point or access point 240 and an information system 250. This system shows a network system developed and compiled on a computer system 205 using various available code 206 and compilers 207. The computer system 205 is then used to load the configurable wireless protocol 221 onto the at least one transceiver 220. An AC Adaptor 270 may be provided for the system 200.
Methods of locating a wireless-enabled device are described, also shown in FIG. 1 and include: providing a wireless-enabled device 110, providing a configurable wireless protocol device 120 comprising a modified wireless-protocol (not shown); and utilizing 170 the configurable wireless protocol device to actively scan 180 for the wireless-enabled device.
As mentioned, a wireless information communication and delivery system is disclosed that includes at least one wireless-enabled device. In one embodiment, wireless-enabled devices provide for or allow two-way communication or at the very least, two-way activation. In one variant, wireless-enable devices are devices capable of utilizing WiFi™, modified WiFi™ protocol or a protocol that is similar in concept and/or function as WiFi™ protocol, such as a configurable wireless protocol. If the wireless-enabled device does not provide for or allow two-way communication, then it may be able to be located by and receive communication wirelessly from another source. Exemplary wireless enabled devices include at least one mobile phone, at least one smart phone, such as the iPhone™, Android™ or Blackberry® Torch™ at least one hand-held device, at least one laptop computer, at least one personal digital assistant or PDA, at least one ear transmitter and the like or a combination thereof.
Device location systems are also included as part of a dynamic wireless network and wireless information communication and delivery system. Device location systems comprise a transceiver or configurable wireless protocol device that may actively configure its signals to enable multiple operating modes, such as short range communication, long range communication or a combination thereof. An exemplary hardware transceiver 300 is shown in FIG. 3 that comprises an outer shell or case 310 with support nubs 315 and hardwire circuitry 320 designed to operate communications systems and related software (not shown). For example, transceivers may be miniaturized, such as the one shown in FIG. 3, which is 1 inch by 2 inches. Exemplary device location systems include a modified WiFi™ protocol that allows for location of and communication with wireless-enabled devices without the wireless enabled device having to actively scan for the transceiver.
In yet another example, a wireless protocol device includes a multimodal transceiver that established a communication network with a local wireless enabled device without first being communicated to by the wireless-enabled device. In one variant, transceivers may establish a communication network with distinct wireless access points or reference points. In another variant, transceivers include a modified wireless protocol software system, which may be modified WiFi™ protocol. In yet another embodiment, a wireless protocol device includes at least one attenuator, such as those already described herein. In one variant, attenuators define an outline a range of space within which the wireless-enabled device(s) is or are detected.
In one embodiment, radio signal strength determines the distance between a device, such as a smart phone and an object that is enabled with a data tag. The radio signal strength is the strength of the radio signal transmitted between the smart phone and the data tag. In another embodiment, the smart phone and data tag may be restricted to matching communication technologies. For example, if the smart phone contains only Wi-Fi service, the data tag may be restricted to Wi-Fi. In yet another example, if the smart phone services contain only Bluetooth, then the data tag may be restricted to Bluetooth only. On the other hand, if the smart phone has Wi-Fi and Bluetooth, the data tag could use either or both, since both the data tags and the smart phone service is implemented by the smart phone manufacturer.
Referring to FIG. 7, a top level description of the iViu system is illustrated with several embodiments of the data tag including communication that occurs between the smart phone, data tag, and databases. Embodiment 1 is a Wi-Fi data tag solution and Embodiment 2 is a Bluetooth data tag solution. Embodiments 3-5 are other technology services that are supported by an iViu system. For example, other technology services include, but are not limited to, Near Field Communication (NFC), Radio Frequency Identification (RFID) and DASH7 and the like.
There are several methods available that are used to report or determine radio signal strength. One method is Relative Signal Strength Indicator (RSSI) which is, for example, reported during a Wi-Fi (or Bluetooth) communication transfer. In the iViu system, RSSI is used to calculate the distance to a data tag enabled object or to the nearest object. Below are described embodiments of the invention related to the use of data tags in conjunction with smart phones.

Wi-Fi System

In this embodiment, the iViu Wi-Fi system operation includes the Wi-Fi data tag transmitting a signal, the smart phone receiving it, and then calculating RSSI. In practice, the solution and its specific implementation(s) may change depending on type, manufacturer, or operation mode of the smart phone, e.g., Android, iPhone. More particular, specifics of IViu Wi-Fi system internal operation may depend on the type, manufacture, operation mode of the smart phone. For instance, a first smart phone (Smart Phone 1) operating in a Wi-Fi scanning mode, e.g., Android, one or more data tag(s) will transmit a periodic beacon signal and the first smart phone performs a Wi-Fi scan to obtain the beacon signal from the one or more data tag(s). The first smart phone uses the received beacon signal and calculates RSSI from it. In this methodology, the reported RSSI is the signal strength of the transmission from the data tag to the first smart phone.
On the other hand, a second smart phone (Smart Phone 2), e.g., iPhone, may not be currently operating in or in a sleep mode for Wi-Fi scanning and thereby does not provide report(s) of RSSI to iViu system. In one alternative, the second smart phone may not have Wi-Fi scanning capability. Advantageously, in either of these instances, iViu system provides another method to obtain the RSSI of the signal transmitted between the data tag and the second smart phone. The method is based upon User Datagram Protocol (UDP) communication. Since UDP is not a handshaking communication method, it does not require a “connection” between the smart phone and the data tag. Therefore, the second smart phone is able to send and receive UDP communication signals between multiple data tags.
In yet another embodiment, the second smart phone sends a UDP broadcast and every data tag that is in range of the radio signal will receive the broadcast. Continuing with this embodiment, the data tags obtain the RSSI of the signal from the second smart phone; and the data tag transmit back a UDP signal to the second smart phone with the RSSI. Therefore, in this method, the RSSI is the signal strength of the signal transmitted from the second smart phone to the data tag. In one variant, the second smart phone may have Wi-Fi services occupied with communicating in UDP mode, which may preclude the second smart phone from connecting to a Wi-Fi access point for data transfer. Thus, while the second smart phone communicates in UPD mode with the data tags, it may not receive Internet traffic from a Wi-Fi access point. Thus in this variant, the second smart phone may be restricted to only receiving Internet traffic using its phone connection, such as 3G or 4G. We can call this the Smart Phone UDP Drawback. As such, this variant may not exist for the other embodiments, such as the Bluetooth or RFID implementation.
Referring to FIG. 8, a communication method is illustrated between the Smart Phone and Wi-Fi data tag. It shows the UDP messaging between the second smart phone and the Wi-Fi data tag, as well as the beacon signal from the data tag and the first smart phone. Another embodiment is the use of the data tags in a dual mode, e.g., Time Multiplexing arrangement. Continuing with this embodiment, during Time 1, the data tag operates in beacon mode for communication with the first smart phone. During Time 2, the data tag operates in UDP mode for communication with the second smart phone. By switching between communication modes at different time intervals, the data tag is able to Time Multiplex and communicates to both the first smart phone and the second smart phone.
In yet another embodiment, an implementation to the smart phone UDP Drawback is disclosed. The solution is based upon the fact that, for instance, a second smart phone may not be in a continual mode of searching for nearby objects. During operation of the iViu application or system, the user switches from a list of nearby objects to obtaining information about a specific object. During the time that the user is out of the list of nearby objects, the phone is switched from the mode of searching for nearby data tags and the phone establishes a link to the Wi-Fi infrastructure. While connected to the Wi-Fi infrastructure, the second smart phone makes a connection to Internet and the Cloud database with information about objects.
Advantageously in this embodiment, while connected to the Wi-Fi infrastructure, the user performs non-data tag related activities, for instance, surfing the web, watching a video, and/or listening to audio or reading text. Once the user returns to the mode of searching for nearby data tags, the second smart phone operating system terminates the connection to the server and restarts UDP broadcasts and messaging with the data tags.

Bluetooth Connectivity

In yet another embodiment, the smart phone obtains RSSI during the discovery process of the Bluetooth data tag. During the discovery process, the first smart phone (Smart Phone 1) may report to its operating system the RSSI of each Bluetooth device it has discovered. The first smart phone uses that information to calculate the distance to objects or the nearest object.
On the other hand, the second smart phone (Smart Phone 2) may have restricted ability to report the RSSI of discovered Bluetooth devices. Consequently, the second smart phone may require the Bluetooth transmission from the data tag to include an encrypted message that identifies the data tag as a manufacture approved product. In one variant, encryption is accomplished by attaching for instance, a special Integrated Circuit (IC), e.g. an MFI chip, to the one or more Bluetooth device.
During the Bluetooth discovery process, the IC sends an encrypted message to the Bluetooth device which is forwarded to the second smart phone. The second smart phone recognizes the encoded message and opens functionality within. Following, operation of the iViu application using the first or the second smart phone are very similar, e.g., the first or second phone uses the RSSI to determine the nearest objects and then serves up information to the user about the nearest object.

Additional Features

In one embodiment, the iViu application and database approach and its operation are independent upon the type of data tag implemented. As additional services are added to the smart phones, the data tag will be adapted to communicate using them. Some examples of possible future services are NFC, RFID, and DASH. An exemplary device location system utilizes native TCP IP protocols to permit detection of relative distance or a specific distance range and those wireless-enabled devices within that distance range without the wireless-enabled device having to scan for the remote, configurable wireless devices. As such, the smart phone may communicate with the data tag even when type of scanning may be disabled. In one variant, one or more device location systems may be incorporated with attenuators to attenuate the signal, which enables the wireless information communication and delivery service to control the range within which the signal will be received.
As will be described in greater detail later, an exemplary configurable wireless device is disclosed of a device that is a part of the wireless information communication and delivery system and is in communication with one or more components, including the wireless-enabled device, the positioning and communication system and the information repository system. In one variant, configurable wireless devices are generally fixed position or stable. In a first instance, the configurable wireless devices may be located near or proximal to a trade show booth, a piece or work of art, or a particular retail item or store location. In a second instance, the configurable wireless devices may be located near or proximal to a ride or attraction at a theme park, an item or group of items that are inventoried or any other article, item or service that someone would be interested in learning more about at a particular time.
In yet another embodiment, some features of device location systems include that the systems comprise configurable wireless protocol or WiFi™ devices, have a modified wireless or WiFi™ protocol combinable with the configurable WiFi™ devices or transceiver. In one variant, these device location systems may be able to control “slave” or dumb devices in order to allow implementation in environments where very low cost devices are required.
In another embodiment, such as Wi-Fi AdHoc mode shown in FIG. 5, there do not need to be any WiFi™ hubs for Internet connection, as mentioned earlier. The configurable wireless protocol device, such as a smart phone, would connect to the AdHoc network when they first arrive in the dynamic wireless network venue or space. In one embodiment, a wireless protocol device does not need to connect to Internet. In one variant of this embodiment, data is not sent to and from Internet while the wireless protocol device is in the venue or space.
In another example, AdHoc networks may provide and send messages between the device location systems, the positioning and communication systems and the wireless protocol device, e.g., one or more smart phones. In this example, because there is no Internet connection on this network, the wireless protocol device will be smart enough to maintain their cell phone carrier's Internet connection, which allows the phones to communicate with the device location systems and the positioning and communication systems via User Datagram Protocol (UDP). The Received Signal Strength Indicator or RSSI will be determined from the UDP messages, and that will indicate which wireless protocol device, e.g., one or more smart phones, the phone is near. As such, the cell phone carrier's Internet connection may be used to communicate with the information repository system to determine with which objects the device location systems and the positioning and communication systems are associated.
Other exemplary dynamic wireless networks and wireless information communication moreover, delivery systems may include a positioning and communication system. These positioning and communication systems provide a measure of accurately and more precisely locate an observer from a number of different vantage points, distance ranges and a number of different time characteristics. The time characteristics may include, for instance, how long the person stands in front of a particular exhibit or booth. Observers are detected by nearby devices and tagged objects, and the relative signal strength will be communicated to the positioning and communication system to let the dynamic wireless network know that the observer is in range of a particular tagged area, including a tagged object, booth, room or other item.
In still other embodiments, positioning and communication systems include a relative location system. These relative location systems may include at least one reference or access point that communicates with the wireless network and wireless information and communication system, along with communicating with one another. In one variant, the relative location system may collect information from the wireless-enabled device, including how long the device (user/observer) stood in a certain place or in front of a certain object (object level accuracy) and send that information to the information repository system.
Advantageously, with a position and communication system, observers not only would get a list of items, objects or locations, but also would obtain valuable additional information, for instance, whether the tagged objects are to their left, right, in front, in back, above or below them. In other words, the observers would obtain distance without any relative direction. The position and communication system uses the fact that observers are in an environment and that the observers move, giving them a different signal strength and estimated distance as they move around in the environment. If one object shows a stronger signal as observer moves, while another object fades, the system will determine that the user is moving toward the object. As larger and larger numbers of these observations of users at different points are recorded, the “perspectives” in the information system are gathered and then used to provide a “learning” method by which more and more accurate information evolves.
In another embodiments, certain “reference” points may be established using the higher power WiFi™ access points in a room that will be place or, if they are already there, will have their coordinate positions relative to a room entrance recorded. The signals from these objects will provide a base from which to calibrate the signals from the other tagged devices and objects in the room. The strength and desirability of these exemplary systems allow tagged object to be located with a level accuracy in a range of, for instance, 1 to 2 meters from the tagged object. For example, this accuracy level is possible because the exemplary wireless information communication and delivery systems use special WiFi™-based or wireless protocol-based tags that intentionally control the signal level combined with the position learning system to provide the increase object level accuracy rather than room level accuracy.
In another embodiment, a positioning and communication system that is part of a dynamic wireless network includes a relative location system. The relative location system assigns a user different or unique signal strength and estimated distance as the user moves around in a specific environment. For example, the specific environment may include a museum, a room, a trade show floor, a historic house, an automobile show, a geographic location, an amusement park, a retail location or a shopping mall.
In one variant, wireless-enabled device may use the TCP/IP broadcast/receive mechanism used in the wireless information communication and delivery systems. Other wireless-enabled device models that allow WiFi™ scanning will use scanning to get the same signals and thus reduce the amount of message traffic necessary, while at the same time save battery life on the tagged objects and related devices. Device based solution associated with a software only solution on the wireless-enabled devices provides an unprecedented level of detail for solutions without any custom hardware on the observer wireless-enabled devices. In yet another variant, wireless information communication and delivery systems may require that software-based digital data tags be associated with the tagged objects and appropriate applications software be downloaded and activated on the wireless-enabled devices as shown, for instance, in FIG. 4 and described in the Examples section.
In one embodiment, wireless information communication and delivery systems may include one or more information repository systems. The information repository systems may include a database or other storage means for storing information about the tagged objects or locations, e.g., whether they are pieces of art, rooms in a historic house, trade show booths and other tagged objects or locations. In one variant, objects and locations that are associated with a place may also be related to associated objects. In another variant, place and object relationships are additionally recursive, so that a place contained in another place may also itself contain other places. In yet another variant, the same is true for objects.
In another embodiment, information repository systems includes a database or other storage means to store information about the observers, users or customers with wireless-enabled devices that are in use with the wireless information communication and delivery system. Information about these tagged places and objects contains associated Uniform Resource Identifiers (URIs). A URI may contain a single Uniform Resource Locator (URL) if it is just a web page or the URI could itself contain various types of information such as videos, audio files, pictures, HTML pages, etc. The information can be updated on the fly or in real time, as information is generated about the item, object, event or company.
In one variant, places and objects may be tagged to both absolute (longitude and latitude) and in addition, relative (x, y, z coordinates based on an entry point) locations. The repository includes a history of movements by observers around the environment. The information repository also includes a “transactions” component that will track expressions of interest by observers in places and objects as well as their route through the places enabled for this type of wireless information communication and delivery systems. The perspectives history contained in wireless information communication and delivery systems enables the positioning functionality used by the position and communication system, which, as mentioned, records distance, signal strength and other information related to the current position of the observer.
In another embodiment, the position and communication system works in concert with the information repository system to track users within the environment, e.g., develop sophisticated demographics and analytics of the users and to push out information regarding moved tagged objects, new or recently tagged objects to the environment, or obtain new information regarding tagged objects and other valuable information. In one variant, systems may allow users to retrieve real-time information regarding objects they are viewing as well as replaying their routes and the information regarding objects that they may have bookmarked during the tour or visit.
In yet another embodiment, one or more timing issues may arise between the wireless protocol device, the device location systems and the positioning and communication systems, as shown in FIG. 6. When engaged by, for instance, an appropriate app, a chosen software application or another software interface, the wireless protocol device will be in “receive mode”. The device location systems and the positioning and communication systems, however, will go into “hibernate” or “sleep mode” either manually or automatically, after a certain amount of inactivity. In this case, various methods can be used to solve any timing issues between the devices and systems.
In one embodiment, the device location systems and/or the positioning and communication systems, wake up and broadcasts a message. The wireless protocol device receives the broadcast message and determines which system it is near. At this point, there are some wireless protocol devices, such as the first smart phone, that are engaged at this point and don't need to proceed forward. However, there may be other wireless protocol devices, such as the second smart phone, that may require additional steps. In these embodiments, the wireless protocol device will send its own broadcast back to the system. The system/systems then record the IP address and RSSI for the device and returns a second message to the identified device. The systems may then enter sleep or hibernation mode for a predetermined amount of time, such as milli-seconds, seconds, minutes or hours.

Messaging Protocol for Positioning of Smart Phone

Referring to Table I, there are outlines of messages that can be processed by wireless-enabled devices, i.e., smart phones. These messages are further described below. FIG. 4 illustrates a digital tag system 400 that may be used for a configurable transceiver. After start 410, the transceiver waits for broadcast 420 and sends or receives several messages, such as Timed Out 421, Hi Power 422, Send Battery Level 423 or Broadcast Received 430. The Broadcast Received mode 430 sends a device query 431 and sends the response 432 back to the transceiver. The Broadcast Received mode 430 will also send a request to the Preferences Mode 440, which is described below.
Continuing with this example, Messages IV00001 and IV00002 are the messages received from and sent to the phones respectively. IV00001 will be received from phones probing for signal strength and thus, proximity. An IV00001 message will contain a comma separated message that will include: IP:xxx.xxx.xxx.xxx, which is the IP of the sending, phone. These IV00001 messages will be broadcast to all devices in range so that all digital tags or OTs receiving this message can respond with their signal strength.
The phone will respond with IV00002, which will contain the device 10 of the device: Initially the MAC address of the wifi-lite or transceiver digital tag. It will also return the signal strength with which it received the IV00001 message from the phone. In one variant, the device will be placed in “Sniffer” mode so that it will see all messages on the network even though it is in “Infrastructure” mode, which would normally ignore any messages not sent to it as an access point. In this “Sniffer” mode, the OT will receive the RSSI directly from the sending phone whereas in normal Infrastructure mode the RSSI would be the RSSI from the nearest access point which would not provide the necessary positioning information to the phone. The responding message will return directly to the phone that sent it.

Preferences Settings Mode

Because the devices may be encountered in a wide diversity of settings the need for them to operate efficiently, saving energy and thus prolonging battery life while also providing rapid response to nearby Observers, the devices will have a “Preferences” mode 440. These preferences will allow the optimization based on the following considerations: a) memory for stored messages and b) response time to requests. For example if we have 100 people moving around and requesting their position every two seconds that would be 30×100 or 3,000 messages per minute. If it slept a minute it would have a long list of messages, plus users wouldn't get answers back until they had probably moved beyond the both where the device is located. If we are fast enough we can probably get away with a 1 second sleep but because we really cannot expect to use a fixed number.
Referring to FIG. 4, Preferences Mode 440 is illustrated where various preferences are, for example, setting battery level frequency 441, TX output control 442, SW1 Control 443, SW2 Control 444, SW3 Control 445, Receive Time 446, Transmit Time 447, Standby Time 448, and Sleep Between Commands Time 449. There may be other preferences as systems are utilized and configured. Preferences Messages: Message IV10000 places the device in “Preferences Mode so that all preferences messages while in this mode will cause changes to the stored preferences. IV19999 with a “1” will cause the device to exit the preferences mode and store the changes in persistent memory. If a “0” is sent with IV19999 the DT will exit preferences mode and throwaway all changes made since entering preferences mode.
Referring to Table I, Device Tags Messaging Protocols are disclosed. The preferences mode will allow control of: Battery time before power level update. Message (Table I) IV20001. This sets the time, in minutes, between the sending of the battery level of the DTs. This is done to monitor the batteries for the need to replace them. The DTs will have to be put in high power mode so that the signal will reach the nearby access points and not just the phones within the low power range. This will be a 5 digit number from 0 to 99999 minutes. 0 indicates that the DT never sends battery information; b) Settings for switches 1, 2, 3 IV20002 sends a 3 digit number from 000 to 111. The Os and 1s indicate the on off state for switches 1, 2 and 3 by position. So, for example, value 111 would turn on all three switches while 010 would turn on switch 2 and turn switches 1 and 3 off; c) Sleep Time; and d) Variable transmit power.
Development Technology: Code will be developed using a GNU C compiler with code cross compiled to the RN171 chip using a development board. Eclipse will be used as a development IDE with the C plug in utilized. Change Control: CVS Change control will be used to provide version control and development team collaboration. Debugging: The GNU Debugger will be used for Debugging.
