Abstract: A system for long range communications is disclosed. The system includes a base station and credit card sized wireless long range communications devices. The wireless long range communication devices each include a transceiver, a man machine interface (e.g., display and pushbuttons), a processor, a power supply (e.g., primary and secondary battery) and an antenna. Preferably, the wireless communication devices are flexible (e.g., like a smart card).

Abstract: A smart container configured for transporting cargo on a transportation vehicle and a method for transporting the smart container on the transportation vehicle are disclosed. The smart container includes a container housing that has an opening for loading and unloading cargo. The opening can be sealed and unsealed. Disposed within the container housing is at least one detector for detecting deviations that could be indicative of possible threats (security concerns). A communications link is also disposed within the container housing. The communications link is capable of transmitting the possible threat information to a central cargo data collection location. For example, the container(s) on a transportation vehicle (e.g., a ship) transport information about the container to a central data collector onboard the ship. The central data collector may then transmit that information off of the ship, e.g., to a C4ISR grid.

Abstract: A method for implementing a timed division multiple access protocol for digital communications between a radio transceiver and a repeater or another radio transceiver has the steps of dividing a radio communication into a plurality of frames having a predetermined length of time; dividing each frame into: a plurality of downlink slots, each downlink slot containing a transmission from the repeater to the transceiver; and a plurality of uplink slots, each uplink slot containing a transmission from the transceiver to the repeater.

Abstract: A personal communication system provides full duplex digital communications between multiple users for both audio and data. A universal adaptor interface receives a plurality of wireless communications. The wireless adaptor interface multiplexes the plurality of wireless communications into a composite signal. The universal adapter interface transmits the composite signal wirelessly. At least one personal communications unit receives the composite signal. Multiplexing the plurality of wireless communications facilitates simultaneous reception thereof by the personal communications units.

Abstract: Data transmission by a half-duplex transceiver over a full-duplex cellular telephone system using the EIA/TIA-553 standard is achieved by monitoring the forward channel to synchronize the transceiver with the forward channel signal, switching to transmit mode to transmit data on the reverse channel, and momentarily switching back to receive mode during the transmission at the projected times of occurrence of significant status bits on the forward channel in order to detect status bits whose timing controls operation of the transceiver.
