摘要： A spread spectrum meter reading system enables the use of high power frequency hopping spread spectrum (HPSS) transmissions at both the encoder transmitter and repeater levels of the meter reading system. A plurality of end point encoder transmitter devices are each connected to a utility meter and transmit high power FHSS signals containing at least metering data for the corresponding utility meter. A plurality of intermediate transceiver units that are fewer in number than the number of end point encoder transmitter devices both receives and retransmits the high power FHSS signals. A base station includes a receiver that receives the high power FHSS signals. Preferably, the base station can receive the high power FHSS signals from both the encoder transmitter devices and the intermediate transceiver units and the intermediate transceiver units aggregates metering data from multiple encoder transmitter devices prior to block retransmission of the metering data to the base station. Preferably, the high power FHSS signals are transmitted at a maximum hopping rate of at least one minute per hop to reduce power consumption and increase battery life of the devices.

摘要： A method and apparatus for transmitting and receiving RF signals for broadband communications using power lines as communication medium. A super-heterodyne structure is used to translate the signals from one frequency to another so as to avoid interference sources, which may corrupt the communication signals. In the heterodyne structure, a plurality of local oscillators are used to mix the local oscillator signals with the communication signals for frequency translation. A plurality of frequency filters are used to filtered out unwanted signals. The communication signals are imparted onto or received from the power lines via couplers operatively connected to modems.

摘要： An electric power line communication system operates with an electric power distribution system to provide through premises power distribution lines highly reliable communication links among power line communication devices electrically coupled or located in proximity to the premises power distribution lines. Each power line communication device associated with a set of premises power distribution lines has an identification address. A master code identifies the power line communication devices as members of a system domain of power line communication devices associated with the set of premises power distribution lines. Association of the master code with the identification addresses renders the member power line communication devices capable of operation without unintended communication with power line communication devices associated with a separate, different set of premises power distribution lines.
