    摘要: A physical layer frequency translating repeater (600, 700) for use in a wireless network includes signal processor (710-714) coupled with a signal processing bus (711), a processor (627) and a memory (650). The physical layer repeater conducts physical layer repeating and selectively conducts layer 2 and possibly layer 3 functions depending on network conditions and other factors. A demodulator (623) can extract address information such as media access control (MAC) addressing to enable packets to be redirected, terminated, stored and forwarded, if necessary, based on network conditions.

    摘要: An antenna assembly includes at least two active or main radiating omni-directional antenna elements arranged with at least one beam control or passive antenna element used as a reflector. The beam control antenna element(s) may have multiple reactance elements that can electrically terminate it to adjust the input or output beam pattern(s) produced by the combination of the active antenna elements and the beam control antenna element(s). More specifically, the beam control antenna element(s) may be coupled to different terminating reactances to change beam characteristics, such as the directivity and angular beamwidth. Processing may be employed to select which terminating reactance to use. Consequently, the radiator pattern of the antenna can be more easily directed towards a specific target receiver/transmitter, reduce signal-to-noise interference levels, and/or increase gain. A Multiple-Input, Multiple-Output (MIMO) processing technique may be employed to operate the antenna assembly with simultaneous beam patterns.

    摘要: A frequency translating repeater (200) for use in a WLAN environment includes an in-band management link. A signal received on an antenna (300) is split to provide signal detection in a detection and control unit (385) wherein detection is performed by detectors (370, 371) filters (375, 376), converters (380, 381) and a processor (385). Delay is added using delay lines (360, 361). The in-band signal envelope may be modulated with variable gain amplifier (330) and demodulated with detectors (370, 371) to establish the management link with higher protocol layer capability. Alternatively, a modern function at least partially compliant to 802.11 modulation may be used in parallel with the frequency translating repeater.

    摘要: A repeater (200) facilitates wireless communication between a first communication device (100) and a second communication device (105) in a wireless network using a time division duplex protocol for data transmission. The repeater (200) includes a receiver (310, 315) for receiving a signal on either of at least two bi-directional communication frequencies simultaneously. A signal detector (362) is operatively coupled to the receiver (300, 310, 315) for determining if the signal is present on at least one of the two bi-directional frequencies. A frequency converter (320, 321, 323, 324, 360, 361) is for converting the signal present on one of the bi-directional frequencies to a converted signal on the other of the bi-directional frequencies. A transmitter (300, 325, 330, 335, 345, 350) is for transmitting the converted signal on the other of said bi-directional frequencies.

    摘要: A varactor based phase shifter that increases phase shift range using a lower characteristic impedance between quadrature ports than is used at its input/output ports. The circuit makes use of a four port coupler arrangement that imbeds a quarter wave impedance transformation between the input port and the quadrature ports as well as between the quadrature ports and the output port. The characteristic impedance across the quadrature ports is therefore less than the characteristic impedance across the input and output ports. In one implementation, reducing a characteristic input/output impedance of 50 to a 20 ohm quadrature port impedance results in a phase shift range increase of more than 50%.
