Systems and methods for network channel characteristic measurement and network management

A method and corresponding system for operating in a network in which stations communicate over a shared medium are presented. The shared medium has at least one varying channel characteristic that varies approximately periodically. The method includes providing repeated beacon transmissions from a coordinator station for coordinating transmissions among a plurality of the stations, wherein at least some beacon transmissions are synchronized to the varying channel characteristic; and transmitting from a first station to at least one receiving station during a time slot determined based on at least one of the beacon transmissions received by the first station from the coordinator station.

Embodiments of the present invention comprise systems and methods for network connection setup and bandwidth allocation comprising negotiable and non-negotiable modulation allocation procedures.

Systems and methods for network channel allocation

A method and corresponding system for communicating between stations in a network is presented. The method includes providing repeated beacon transmissions from a coordinator station for coordinating transmissions among the stations; transmitting a signal from a first station and receiving the signal at a second station; and performing one or both of: generating the signal based on a local clock at the first station and time adjustment information in a beacon transmission received by the first station, and sampling the signal at sample times based on a local clock at the second station and time adjustment information in a beacon transmission received by the second station.

Time synchronization in a network

A method and corresponding system for communicating between stations in a network are presented. The method includes providing repeated beacon transmissions from a coordinator station for coordinating transmissions among a plurality of the stations; transmitting from a first station to a second station during a time slot assigned to the first station by at least one of the beacon transmissions; and transmitting from the first station information that grants permission to the second station to transmit during at least a portion of a time slot assigned to the first station.

Managing contention-free time allocations in a network

Methods and apparatus for detecting the presence of a particular signal among all the channels of interest in a cellular or similar type system are disclosed. A first method detects CDPD signals, and a second method detects DQPSK signals used in digital control channels in accordance with the IS-136 standard. These methods include the steps of sampling a received signal in at least one channel to obtain a predetermined number of samples for the at least one channel; computing an error value for each sample; determining a minimum error value; determining a ratio of the minimum error value to a reference value; and making a decision as to whether the received signal is the prescribed signal on the basis of at least the ratio, wherein the decision is made by comparing the ratio to a threshold value.

Methods and apparatus for detecting the presence of a prescribed signal

A method for reducing power consumption in a cellular telephone by placing the receiver in a sleep mode when it is determined that the received signal has a sufficiently high quality. The duration of the sleep mode is extended by eliminating the need to resynchronize the receiver clock to the transmitter clock using dotting sequence and synchronizing data in the transmitted control data received after a sleep cycle. This is accomplished by resynchronizing the phase of the symbol clock to the phase of the transmitter clock after a sleep cycle utilizing the respective phase relationships to a low frequency, low power maintenance clock in the receiver which maintains time (and hence edge information) during the sleep mode until reception of the next data frame must begin. The maintenance clock is preferably an off-the-shelf oscillator of the type used in wrist watches. At a specified tick of this clock, which is known to the receiver before it goes to sleep, the high-speed system clocks are turned on in preparation for reception of the next frame of data. Since the phase relationship of the symbol clock to the maintenance clock prior to the sleep mode was known, the phase of the symbol clock is readily recreated after the sleep cycle from the known phase of the maintenance clock, which is never turned off.
