    Abstract: A radio telephone communication system (200) having a base station (203) including at least one frequency agile time division duplex transceiver (207) for facilitating communication with at lest one radio telephone (100) on the at least one radio frequency channel. The radio telephone (100) scans a plurality of channels capable of being generated by the at least one frequency agile transceiver (207) to find an available channel and provide an indication representing a base station busy status when all the at least one frequency agile transceivers are in use. A base station busy status is indicated when one of a bidirectional time division duplex communication including a base station identification signal is being communicated by the at least one frequency agile transceiver or a unidirectional time division duplex communication including a base station identification signal is being communicated by the at least one frequency agile transceiver (207).

    Abstract: A paging system includes a transmitter for transmitting a carrier frequency signal modulated by subaudible tone signals in response to audible tone signals coupled to the transmitter from a remote point. An encoder at the remote point develops the audible tone signals which are coupled to the transmitter over standard telephone channels. At the transmitter, a circuit converts the audible tone signals to first square wave signals having the same frequency as the audible tone signals. A divider circuit divides the first square wave signals by a particular number to develop second square wave signals having the same frequency as the desired subaudible tone signals. The second square wave signals are coupled to a low pass filter which attenuates all frequencies above the subaudible tone signal frequencies and develops a sine wave having the desired subaudible tone frequency.

    Abstract: A radio telephone communication system (200) comprising a base station with at least one frequency agile transceiver (207) capable of time division duplex operation on at least one radio frequency channel. The base station operates to facilitate communication with at least one radio telephone (100) on the at least one radio frequency channel. The radio telephone communication system further comprises a radio telephone (100) capable of determining an acquisition status of the at least one frequency agile transceiver in the base station, the radio telephone (100) generating an indication representing a base station busy status (402) when one of: requesting a time division duplex communication link fails and bidirectional time division duplex communication is exists on the radio frequency channel; and requesting a time division duplex communication link fails and unidirectional time division duplex communication exists on the radio frequency channel and the unidirectional time division duplex communication originates from the base station.

    Abstract: A wireless communication network (100) employs a method and apparatus for reliably communicating information packets in the network. A first wireless device (101) in the network transmits an information packet to a second wireless device (e.g., 102) in the network over a first wireless communication channel (403, 404). The first device then determines whether the information packet was successfully received (e.g., received without errors) by the second device. If the information packet was not successfully received, the first device retransmits the information packet to the second device over a second wireless communication channel (405, 406). In addition, and preferably substantially contemporaneous with retransmission of the first information packet, the first device transmits a second information packet to the second device over the first channel in an effort to communicate an information sequence to the second device without delays typically associated with use of a reliable protocol.
