Companding Frequency Shifting Repeater

We are offering our customers a wide range of Companding Frequency Shifting Repeater. The remote village cana t receive the signal from town base station because of long distance. If we adopt the original signal frequency of 900MHz and 1800MHz, ita s easy to affect by the outside condition and the loss of wireless propagation path is biggish. Also the signal is easy to block off by the complicated Montana landform. So we need a system which uneasy to affect by outside condition and with powerful diffraction to transmit and cover, achieve large-scale wireless communication service to villages.
Direct against the above situation, the Enclave Companding System has researched. It compress the communication signal form wide bandwidth to narrowband via simulate channelized, band selective or digital channelized, then transmit the signal in long distance. The Enclave Companding System compress the donor signal from 24M bandwidth of 900M band to 4M bandwidth of 150M or 230M band, in remote expand the intermediate frequency to the original 900M band, then cover after linear amplification. The advanced compression and filtering technology debase the device interference to network system. Availably solve the signal coverage problem in hilly, mountainous and silvan areas, also in coverage areas with lean frequency resource.
