A method is described of calculating and verifying the integrity of data in a data communication system. The system comprises a base station and one or more remote stations, such as in an RFID system. The method includes transmitting a select instruction from the base station to the one or more remote stations, the select instruction containing a data field which matches a portion of an identity or other data field in one or more of the remote stations; transmitting from a selected remote station or stations a truncated reply containing identity data or other data of the remote station but omitting the portion transmitted by the base station; calculating in the base station a check sum or CRC from the data field originally sent and the truncated reply data received and comparing the calculated check sum or CRC with the check sum or CRC sent by the remote station.

A personal communication and electronic commerce system for use by participating users and participating merchants in connection with incentive programs in the Network Economy. The system includes a cellular communication network that includes geographically spaced base stations that are linked to a fixed communication network. Users may have personal communication devices that can be used to allow a digital message generated on the personal communication devices by placing a call through one of the base stations and memory for storing a digital value corresponding to a monetary value. The personal communication device may also be used as a cellular position locator to determine one's geographic location and, if desired, to access information from a merchant information database containing information pertaining to a plurality of participating merchants located within the geographic territory covered by the cellular communication network. The merchant information may be stored on a database that is accessible by merchants so those merchants can add, delete or alter information contained in their respective listings. An incentive system is also provided for creating incentives for participating users to encourage. This computer implemented incentive program for encouraging certain participant actions includes a first reward program under which participants may earn points for certain actions and a second reward program through which the redemption rate associated with a particular participant is adjusted in response to certain participant action. The incentive program has a wide range of applications, including transportation, financial services and computer gaming.

A wireless communication method and apparatus are described for increasing security for communication devices utilizing identification chips for accessing wireless networks and the associated billing for services. One aspect of the invention is an enhanced phone chip and a communications device adapted to engage the enhanced phone chip, which then cannot be installed or removed from the wireless communications device by unauthorized users. In one embodiment a security key mates to the identification chip and is utilized for installing and removing the enhanced phone chip. The security key preferably has a display upon which information about the communication device is displayed prior to removing the security key after installing the enhanced phone chip. Other aspects of the invention include wireless base station communication devices which support wired (dedicated and non-dedicated), and more preferably wireless extensions, while providing sharing of wireless network resources and interconnectivity between base station and extensions.

Systems and methods are provided that use a mobile robotic device to transport rechargeable batteries between a base station, which charges the batteries, and a battery operated device, such as battery powered kiosk or signage system, which uses a charged battery as a power source. After traveling to a battery operated device, the mobile robotic device removes any discharged batteries from the battery operated device and installs a charged battery. The mobile robotic device then travels to the base station and attaches the discharged battery to the base station for recharging. The mobile robotic device may be configured to perform other transfers, such as data transfers and paper transfers. In addition, the mobile robotic device may be configured to perform a photographic and spatial survey of the isles, retail shelves, and surrounding environment for various purposes, such as generating three-dimensional store models and remote viewing.

Apparatus for remote interaction with an object of interest includes a remote station for obtaining information from the object of interest, a base station for transmitting energy in space to and communicating with the remote station and the remote station having conversion means for energizing the remote station responsive to receipt of the transmitted energy. The energy may be of any suitable type including RF power, light, acoustic, magnetic energy or other form of space transmitted or "radiant" energy. The remote station does not have to contain a source of stored energy or a wired connection to a source of energy. The remote station receives the energy transmission and data transmission from the base station and transmits data to the base station. Microprocessor controllers may be provided for the base station and the remote station. The remote station may receive information from sensors and through one or more transponders sequentially communicate information to the base station. An associated method is provided. In other embodiments which are suited for use in miniaturized electronic chip systems, power enhancement and increased effective antenna size are provided. An electronic article containing a microchip having at least one antenna structured to communicate with an antenna remotely disposed with respect to the microchip formed therein and an associated method are provided.

There is disclosed a radio communication system in which a constitution of a base station and further a control station can be simplified. A radio communication system according to the present invention converts a received signal received by a plurality of antenna elements in a base station to a signal of different frequency band, and then conflates the converted signal in order to generate sub-carrier wave multiplex signal. The signal is converted to an optical signal, and then the optical signal is transmitted to a control station via an optical fiber. Or the control station performs weighting to phase of the transmitted signal transmitted from a plurality of antennas of a base station, and then performs frequency conversion to different frequency band, and then conflates the converted signal in order to generate the sub-carrier wave multiplex signal. The signal is converted to an optical signal, and then an optical signal is transmitted to the base station side via the optical fiber. The control station and the base station divides the received sub-carrier wave multiplex signal by each frequency band, and then the frequency of the divided signals are converted to the same frequency band in order to generate the transmitted / received signal of each antenna element. By such a constitution, it is possible to reduce constituent of the optical transmission components to the minimum and to simplify the constitution of the base station. Furthermore, it is possible to maintain the relative phase difference and the relative intensity of the transmitted / received signal of each antenna element. Because of this, it is possible to estimate an arrival direction of the received signal and to control radiation beam pattern of the transmitted signal.
