LG to launch first wireless HDMI (WiDi) TVs

20.05.12

With excitement for the Consumer Electronics Show (CES) building as the date draws near, LG has announced that it’s launching the world’s first native Wireless Display (WiDi) televisions. WiDi is more commonly known as “wireless HDMI” for its ability to stream high definition content over a 4Gbps data connection. Partnering with Intel, the first 3D versions of LG’s wireless HD televisions should start rolling out sometime next year, with CES attendees getting the first look at them next month.

WiDi operates in the 60GHz extremely high frequency (EHF) band. Because of the amount bandwidth available in that spectrum, it has the capability of transmitting both compressed and uncompressed high definition content. With a theoretical top speed of 25Gbps, it certainly has the power to get the heavy lifting of high definition done. Currently the technology has a fairly strict limitation in that the transmitter needs to be able to “see” the receiver in the television, but it’s a major goal of the companies involved to develop the standard to the point where this is no longer needed.
