    Abstract: An exemplary method (600, 700) and apparatus (800) are provided for generating a modified protocol message (414, 423 a, 423b, 424). In some embodiments, a physical layer repeater conducts a repeating operation including receiving a modified protocol signal on a first channel and retransmitting a modified version of the modified protocol signal on a second channel. An exemplary physical layer repeater can include a transceiver (810), a baseband modem (822), and a processor (821) configured to demodulate the modified protocol signal to obtain a first identifier and a first channel identifier and a unique identifier in a modified portion of the signal. The unique identifier and a second channel identifier are retransmitted in a modified version of the signal on the second channel.

    Abstract: A method and apparatus are provided for operating a frequency translating repeater in a wireless local are network (WLAN) having one or more repeaters (200, 204), a network protocol for communicating between one or more base units (100) and one or more client units (104, 105). A first frequency channel may be used for receiving and transmitting, the network protocol defining multiple operating frequencies monitored to detect a transmitted signal. The signal is characterized to determine if associated with the base units. A second frequency channel selected for use by one of the repeaters for retransmission of additional signals based on the characterization.

    Abstract: A frequency translating repeater (120) for use in a time division duplex (TDD) radio protocol communications system includes local oscillator (LO) circuits (210, 310, and 410) to facilitate repeating by providing isolation, reduced phase noise, reduced pulling, and the like. Tunable LOs (441, 442) can be directly coupled to down-converters (413, 414) and up-converters (426, 427) for increased isolation, reduced phase noise, less stringent frequency accuracy, and a reduced potential for pulling.

    Abstract: An antenna configuration includes two closely spaced antennas each positioned so as to be orthogonally polarized with respect to the other. The antenna configuration increases antenna isolation and reduces electromagnetic coupling between donor side antenna and repeat side antenna. The antennas include printed dipoles connected to respective transceivers through respective baluns to balance the non-symmetrical portions of the antenna feed paths to reduce unwanted radiation therein. Printed features such as chokes and non-symmetrical and non-parallel structures are preferably included in the ground plane of a multi-layer circuit board to reduce or eliminate circulating ground currents.

    Abstract: Combinations of correlation results are used to achieve detection of multiple coded signals at a receiver in a wireless communications system. The code applied to signals includes a lower rate code and a higher rate code. The lower rate code is a nested or tiered code such that it comprises at least two code sequences of the higher rate code. The received coded signal is correlated with the higher rate code using a single higher rate correlator to provide a higher rate code correlation result. The higher rate code correlation results are fed to two or more lower rate code correlators that combine multiple higher rate code correlation results, each using a different lower rate code, to provide corresponding lower rate code correlation results. The presence of at least one coded signal or mutually exclusive coded signals can be determined from the lower rate code correlation results.
