An embodiment of a mobile communication system includes a plurality of mobile units operating within a defined operating area, each of the mobile units having a processor, a memory for storing a mobile unit file structure, an application running on the processor for operating on the mobile unit file structure, and a receiver for receiving on a common receive communication channel data. The mobile communication system further includes a plurality of geolocation markers disposed within the defined operating area, each having a memory for storing geolocation information to define a relative position within the defined operating area, and a geolocation transmitter for transmitting the defined geolocation information on the common receive communication channel, the geolocation transmitter having a geolocation transmit range less than the defined operating area.

Urban mobile network system

A mobile network comprising a central unit () for communicating with a first network (); at least one intermediate base station () for communication with the central unit () over the first network () and for transmitting data to a second network; at least one mobile unit () for receiving data from the base station over the second network, a memory for storing the data, a display and a processor running an application to display at least a portion of the stored data; and at least one geolocation marker () external to the mobile unit for generating a signal including position information indication a relative position, wherein the signal is received by the mobile unit when it is proximate to the base station wherein the central unit broadcasts at least one portion of the data to the mobile unit through the intermediate base station; and wherein the application running on the processor displays a portion of the stored data associated with the relative position.

A method is disclosed for controlling the operation of a low power radio platform that realizes the physical layer (PHY) with a software portion and an analog front end, the analog front end disposed between the DSP and an antenna, and realizes the MAC layer with a microcontroller unit (MCU). The DSP, analog front end and MCU are maintained in a low power mode of operation when not in data communication. When data communication is initiated, a hardware controller controls at least one hardware interface disposed between the DSP and the analog front end to initiate multiple time based tasks to transfer data to and from a buffer. During the execution of these tasks, the controller causes a task in the DSP to be initiated for processing of data in the buffers and, upon completion of at least one of the tasks, notifying the MCU of such. The controller controls the hardware interface to terminate operation when predetermined time based events have occurred. The MCU in at least one mode of operation thereof is operable to initiate the operation of the hardware controller and then convert to a low power mode of operation to await notification.
