SYSTEM AND METHOD FOR DATA DISTRIBUTION IN VHF/UHF BANDS

摘要

The White Space device is WiFi OFDM signal can be used to non- television frequencies are used to transmit and receive . Such as a conventional channel 2 , 3 , and 4 , the three adjacent bands , may be combined together to define a space , and white band . For the same to apply a WiFi OFDM signals into the whitespace band (fit), a white space, the device is to use a specific spectrum mask and compresses the WiFi OFDM signal bandwidth each . For the modified WiFi OFDM signal requires a very low transmission power , eliminating the need for high- power amplifier , WiFi OFDM PHY and MAC design , such as the most can be used again only with a minimum of modification . ;
