  • Publication number: 20150207589
    Abstract: An endpoint element of a distributed antenna system includes processing circuitry configured for processing a plurality of digital signals for conditioning the signals and compression circuitry configured for compressing at least one of the digital signals according to a compression scheme to yield at least one compressed digital signal and compression settings. The digital signals are combined into a single digital stream and combined and time division multiplexed onto a serial data link with the compression settings. The digital signals are also transmitted with compression settings to another endpoint element over the serial data link.

  • Patent number: 9077517
    Abstract: Embodiments of the invention provide a method, distributed antenna system, and components that generate a jitter reduced clock signal from a binary encoded data stream transmitted over a communication medium. The method includes receiving a modulated signal that includes the binary encoded data stream and generating a recovered clock signal that is phase locked to the binary encoded data stream. The method further comprises generating a stable recovered clock signal by filtering the recovered clock signal to remove jitter, while allowing the clock signal to track long-term drift.

  • Patent number: 8909133
    Abstract: A system and method of monitoring a signal repeating device in a wireless communication system is provided. An operational noise measurement is obtained by measuring a noise value outside of a bandwidth of a first element, but within a bandwidth of a second, subsequent element in a signal path of the device. The operational noise measurement is alternatively obtained by tuning an input band of the device to shift the input band partially or completely outside of a bandwidth of a first element to create an open band or by suppressing an input of an antenna and measuring noise within the open bandwidth of the device. A stored parameter is retrieved and compared to the measured operational noise. Alternatively, a leakage signal of the device may be received at a signal receiver and compared to a reference. The reference is a function of elements of the device in a leakage path of the leakage signal.

  • Patent number: 8681917
    Abstract: Embodiments of the invention provide a method, distributed antenna system, and components that generate a jitter reduced clock signal from a serial encoded binary data stream transmitted over a communication medium. The method comprises receiving a modulated signal that includes the encoded binary data stream and extracting the encoded binary data stream. The method further comprises generating a recovered clock signal that is phase locked to the encoded binary data stream, generating an error signal based on a difference between a phase of the encoded binary data stream and the recovered clock signal, and integrating the error signal to generate a signal to control a voltage controlled oscillator. The method further comprises generating a stable recovered clock signal and producing at least one output clock by scaling the stable recovered clock signal frequency.

  • Patent number: 8594223
    Abstract: A distributed antenna system having improved data transmission features incorporates endpoints of the system, which are coupled together by serial data link. At the endpoints, processing may occur utilizing processing circuitry to determine similarities between multiple signal streams. If the streams are similar, the data sent over the serial digital link is reduced by only sending one of the representative signals. In an alternative embodiment of the invention, the difference between the signals might be sent as well. Alternatively, all signals might be sent, but may be compressed with compression circuitry before the signals are transmitted over the serial link. At the endpoint of the system, the signals are reconstructed for further processing and transmission.

  • Publication number: 20110243201
    Abstract: A broadband transceiver includes at least one layer structure that is substantially impermeable to RF radiation. The layer structure includes a first face surface substantially opposite a second face surface. A receive antenna is located proximate the first face surface and configured to receive RF transmissions. A transmit antenna is located proximate the second surface and configured to transmit RF transmissions. At least one of the receive and transmit antennas generates a generally toroidal radiation pattern that is stronger in a direction substantially parallel to the respective layer structure face surface compared to a direction substantially perpendicular to the face surface.
