UHF to 2.4 GHz Translator

UHF to 2.4 GHz Translator Overview

The UHF to 2.4 GHz Translator permits system integrators to deliver WiFi-like network access via the “white spaces” of un-used TV bands. Our white space components convert ultra-high frequency (UHF) signals to 2.4 GHz (802.11g), providing a commercially viable radio-based communications network product.
