Dekolink’s new Digital Channel Selective Repeater
employs advanced Digital Signal Processing technology
(DSP) that provides significant advantages over
conventional repeaters.
This innovative system introduces new system
capabilities, which enable a wide variety of applications
particularly when adjacent channel selectivity and very
high spectral purity and selectivity is required.
The Digital Channel Selective Repeater generates a flexible
array of 8 DSP based software controlled independent variable
bandwidth channels across the whole 800 MHz SMR band.
Each channel parameters such as central frequency,
bandwidth, and filter slopes, are all software controlled in a
local mode and can be remotely controlled via a wireless
modem.
The 800 MHz SMR band is crowded with many different
services. Services such as IDEN, LMR, SMR and Public
Safety are interfering with each other in the same geographical
area making it often impossible to support these services
simultaneously.
The Digital Channel Selective Repeater provides a very efficient
solution to the 800MHz interference problem by enabling high spectral
selectivity while maintaining a clear low noise spectrum.
The Digital Channel Selective Repeater has a built-in software controlled
frequency shift capability making this product ideal for those
applications where frequency shifting is required and particularly in sites
where high gain is required under poor antenna isolation conditions.
Dekolink’s Digital Channel Selective Repeater provides a 40dbm
composite output power, ideal for outdoor applications. Dekolink
also provides a cost effective medium power system providing the
same features and capabilities but with 32 dBm composite power.
These amplifiers are an excellent choice for in-building coverage
applications when frequency selectivity is required.
