UHF Translator
Overview
The UHF to 2.4 GHz Translator permits system integrators and developers to deliver WiFi-like wireless networking systems via the “white spaces” of un-used TV bands. MSC white space components convert 802.11 OFDM signals to the UHF band. Power can be adjusted at one dB increments from 1 Milliwatt to 1 Watt. The receive chain converts the received UHF signal to any channel within the 802.11g band.
