摘要： A communication device locates a wireless service provider in a multi-service provider environment using a frequency band search schedule. The frequency band search schedule has a first or home band and a several other frequency bands in a predetermined order. The order of the frequency bands may be programmed by the user or by a home service provider over the air. The communication device searches for an acceptable service provider by examining the home band and then the other bands listed in the frequency band search schedule. The bands are examined in the order specified by the frequency band search schedule. An acceptable service provider is identified by comparing the identity of a service provider specified by an identifier received from a band being examined with a list of acceptable service providers.

摘要： A frequency-hopping communication system preempts certain burst frequency assignments. The communication system is capable of communicating to mobile stations (114, 115) via a radio channel (121) in a TDM/TDMA mode. A plurality of mobile stations are assigned burst frequencies for transmission during timeslots of the TDMA system. To support additional mobile stations without additional burst frequencies, the communication system preempts the burst frequency assignment from the plurality of mobile stations, and utilizes the preempted assignment to support communication to the additional mobile stations.

摘要： A receiver block comprises a receiver circuit, a down-converter, a mixer, a modulator circuit, a decoding circuit, a synchronization circuit, a spread code control unit, and a frequency synthesizer. No synchronization holding circuit is needed. MSFK and PSK are used as a primary modulation. Synchronization is initially acquired by repeatedly mixing a part of the frequency hopping code sequence. Synchronization is improved during a period arranged separately from data communication periods. Before data transmission, the primary modulation components are fixed and transmitted for two code periods. The time changes in phases attributed to secondary modulation components will be known. After this, the primary modulation components are found.

摘要： The present invention is an apparatus and method thereof for performing frequency hopping communication with another party over a subset of hopping frequencies from available frequencies. The spectrum is arranged into a plurality of segments, with each segment corresponding to a subset of the spectrum of frequencies, preferably a contiguous subset of the spectrum. The apparatus includes a communication device for communicating with another party. The communication device receives data over a used segment from a plurality of the segments and signal strength data indicating a current reception power level for the hopping frequency from the other party. A processing unit analyzes the received data to determine an occurrence or non-occurrence of an error over the used segment and notifies the other party to modify the current transmission power level for that used segment according to the occurrence or non-occurrence of an error, via said communication means. Through such information exchange, the other party can independently control and optimize the transmission power level for each used segment, e.g., to a minimum transmission power level at which no error has occurred.

摘要： A frequency-hopped mobile communication system is disclosed, in which a mobile wireless station automatically becomes a base station in accordance with the surrounding conditions, thereby automatically reconfiguring a communication network. A control frame is generated by at least one master station, and frequencies are hopped by a plurality of slave stations in accordance with the control frame. Each slave station switches the master thereof to be tracked, in accordance with the receiving conditions of the control frame and the relation between the control frame received from the master station and the status of the slave station and decides in which mode, master station or slave station, the slave station is to operate. The cells are thus automatically reconfigured.

摘要： A synchronized frequency hopping method and apparatus for use in a cellular communication system where the cellular communication systems has a plurality of cells and a plurality of frequencies available to be assigned to the cells. At predetermined times, cells in the system synchronously change or hop to a new frequency. The new frequency to which a cell hops to may be a function of the present frequency the cell is assigned. In addition, synchronized frequency hopping may occur at predetermined intervals and the pattern of hopping may periodically repeat. This technique limits the period of time a non-system source of interference may impair communications in any cell since the cell hops to different frequencies periodically.

摘要： An SMR repeater is made agile by adding a microprocessor controlled frequency selection circuit to enable the repeater to operate on any one of several available frequencies in a band. For dispatch service, the output of the repeater is switched to a power amplifier feeding an omni-directional antenna. The repeater scans several frequencies sequentially. If a signal is detected, scanning is halted to provide repeater service, after which scanning is resumed. The frequency agile repeater is coupled to an antenna system having a narrow beam which can be steered electronically. A control computer scans the azimuth of the beam. The computer divides a service area into a plurality of cells extending radially from the antenna system and assigns channels as needed to service a subscriber. More than one cell can be on the same frequency without interference. The microprocessor includes a table in memory of call signs corresponding to particular transmission frequencies and causes the repeater to transmit the appropriate call sign when transmitting at a particular frequency.
