Abstract: PROBLEM TO BE SOLVED: To provide a local oscillator architecture in a frequency translating repeater structured to extend a communication-enabled area in a wireless environment. SOLUTION: The frequency translating repeater for use in a time division duplex (TDD) radio protocol communications system comprises a plurality of local oscillator (LO) circuits to facilitate repeating by providing isolation, reduced phase noise, reduced pulling, and the like. Tunable local oscillators 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: A repeater environment is provided operative to deploy a feedback cancell ation loop that is adaptively coupled with an antenna array such that a sele cted metric can be derived by deploying a selected filter bank having an aut omatic gain control operative to process the signal on a bin by bin basis an d the derived metric can be applied to the antenna array and feedback cancel lation loop combination to improve signal integrity and amplification. In an illustrative implementation, an exemplary repeater environment comprises, a transmitter, a receiver, an equalized feedback cancellation loop circuitry comprising a filter bank, the cancellation loop being operatively coupled to an antenna array. In the illustrative implementation, the feedback cancella tion loop can receive signals as input from a cooperating antenna array and provide output signals such as a feedback leakage signal to a cooperating an tenna array.

Abstract: A wireless repeater extends a coverage area of a wireless network base station within a structure or facility. The repeater includes a master unit for wirelessly communicating with the wireless network base station and a slave unit for wirelessly communicating with one or more subscriber terminals. The master unit is connected to the slave unit through new existing wiring in the structure to enable the master unit to transmit wireless signals to the slave unit on a downlink transport frequency and to receive wireless signals from the slave unit on an uplink transport frequency in a manner that is transparent to the wireless base station and the subscriber terminals.

Abstract: A first repeater operating within a wireless network including a second repeater capable of communicating with the first repeater, and first and second wireless station devices capable of communicating with at least one of the first repeater and the second repeater, includes a reception device for receiving a wireless signal at a reception frequency; a detector for detecting if a predetermined portion of the received wireless signal includes a modified portion to thereby determine that the received signal is from the second repeater; and a transmission device for transmitting the wireless signal to one of the first and second wireless station devices at a transmission frequency to thereby repeat the wireless signal.

Abstract: Methods and systems are provided to generate digital coefficients for a f ilter. The generation of coefficients relies on a Fourier transformation of an impulse response in time domain that is zero padded, e.g., zeros are appe nded to an array corresponding to a sampled input signal of length M. A unit prototypical filter is generated through a frequency domain response of len gth NFFT = Ns+M-1, wherein NS is a sampling length of the incoming signal. T he unit prototypical filter is then circularly shifted in order to generate a band pass filter centered at a desired frequency. Circularly shifted filte rs are point-to-point added to generate a set of composite digital coefficie nts to filter the incoming signal. The reference frequencies for the composi te filter are extracted from a message received from one or more base statio ns associated with one or more service providers. The composite filter typic ally operates on a frequency repeater.

Abstract: Methods and systems are provided to configure a frequency repeater. The f requency repeater is configured with an identity of a service provider and r eceives a message that defines a set of frequencies to be repeated, the freq uencies are associated with a service provider that matches the preconfigure d identity. A digital filter receives an incoming signal from the service pr ovider, and filters and repeats the frequencies defined in the received mess age. The frequency receiver can also determine a set of frequencies to be fi ltered and repeated based on a cell search procedure performed with a modem that resides in the repeater. A policy established by the service provider c an also be utilized to facilitate defining the set of figures to be repeated . By utilizing a signal quality metric and an isolation metric associated, w ith the performance of a receive and transmit antenna utilized by the repeat er, the set of frequencies to be filtered and repeated can be adapted in rea l time.
