摘要： A telecommunications system is provided that can re-sample a digitized signal at a resample rate that is based on one or more factors to better utilize bandwidth. The factors can include the bandwidth of the signal that the digitized signal represents, the amount of bandwidth owned or used by the carrier, the full bandwidth of the designated RF band, the bandwidth of the serial link, the frame length of the serial link, the segmentation of the frames on the serial link, and the capability of the equipment at the receiving end of a serial link. The re-sampled signal can be transmitted to another unit that is remote to the unit transmitting the signal. The other unit can include a re-sampling device that restores the re-sampled signal to a digital signal that can be converted to an analog signal for wireless transmission.

摘要： A method of monitoring an element in wireless communication system is provided. An operational noise measurement is obtained by measuring a noise value outside of a bandwidth (304) of a first device, but within a bandwidth (302) of a second, subsequent device. The operational noise measurement is alternatively obtained by tuning an input band of the element to shift the input band partially or completely outside of a bandwidth (404) of a first device to create an open band or by suppressing an input of the antenna and measuring noise within the open bandwidth of the element of the wireless communication network. A stored parameter is retrieved and compared to the measured operational noise. Alternatively, a leakage signal of the element may be received at a signal receiver and compared to a reference. The reference is a function of components of the wireless communication system in a leakage path of the leakage signal.

摘要： Systems and methods for developing a configuration plan for communication transport links of a distributed antenna system are provided. The distributed antenna system includes a unit communicating with remote antenna units over the communication transport links. The unit receives signals from base stations. Characteristics of each of the signals are determined. The characteristics include, for each signal, a frequency occupancy, a digital bandwidth, and a coverage zone to which to provide the signal. The frequency occupancy includes the minimum frequency component and the maximum frequency component of the signal. The digital bandwidth is a bandwidth for communicating the signal via the communication transport links. A hardware capability of the distributed antenna system, such as a respective available bandwidth for each communication transport link, is also determined. The configuration plan for transporting the digital representations of the signals is determined based on the hardware capability and the characteristics of the signals.
