Wireless researchers from Rice University have developed a way to make the most of the unused UHF TV spectrum with the creation of a multiuser, multiantenna transmission scheme. The UHF band is traditionally used for television broadcasts.
The scheme uses multiple-input, multiple-output (MIMO) to utilize several antennae to boost data rates without additional channels or transmitter power. The UHF-band multiuser MIMO was tested at 2.4GHz, and 5.8GHz WiFi using the University wireless open-access research platform (WARP), and side-by-side results showed that the transmission scheme produced high spectral efficiency and low-overhead wireless access. The use of UHF spectrum for broadband internet would be ideal in rural areas where wired broadband is not available.
