About This Product

Digital repeater that meets both existing public safety communication regulations and future mandates.

Westell Technologies developed its digital repeaters for use within enclosed structures where sufficient signal from local cell sites to operate cell phones is unavailable. Adequate signal must be available outside the structure as a prerequisite to achieving in-building coverage. The digital repeater is connected to an external antenna, usually on the roof, and to one or more internal antennas placed strategically throughout the area where wireless service is desired.

With a maximum total of 90 dB nominal gain on both the uplink and downlink, gain can be adjusted over a range from 58.5 dB to 90 dB in 0.5 dB steps. Control of the repeater is achieved utilizing a computer connected to COM port or via a crossover Ethernet cable connected to the Ethernet port.

A specific filtering process modifies each amplification chain. This process digitally converts the assigned spectrum and then applies DSP techniques. DSP is used to create passbands that selects the RF energy passing through either the uplink or downlink paths. After the digital processing is complete, the information is converted back to an analog signal that is applied to the remaining stages of amplification. The resulting signals emitted by the repeater are specific to the network service providers’ requirements. If these requirements change, only the DSP configuration parameters need change in order to adapt. Configuration parameters are created at the factory and supplied as files that may be downloaded to the repeater. The filter set configurations stored in memory determine the unit’s adaptability to various field applications. The following pages describe the band plans as well as the convention Westell Technologies uses to identify and store the files that make up the filter set. All Westell Technologies repeaters are shipped with an active filter set that is programmed according to the ordering parties’ specifications. In most cases, the installer will not be required to program a filter.
