WirelessHD

(WIRELESS High Definition) A short-range wireless video technology from the WirelessHD Consortium. Using the unlicensed 60 GHz band, WirelessHD (WiHD) transmits 1080p HD video from a data source to a TV within approximately 30 feet. With a data rate of 28 Gbps, Version 2.0 of the standard is capable of handling very high-speed data, including 3D and 4K video resolutions.

At 60 GHz, the five-millimeter wavelength is highly directional. However, in 2007, SiBEAM demonstrated CMOS chips that can bounce the signal off walls and objects using an array of up to 36 antennas on a 1" square surface. For more information, visit www.wirelesshd.com. See wireless USB, WiGig, WHDI and ISM band.


Automatic Redirection
As soon as a person interrupts the signal, WirelessHD uses another route to reach the TV; in this example by bouncing off the back wall. Using beamforming techniques, the transmitter is constantly scanning for alternate pathways to the receiver in order to make a quick switch if necessary (see beamforming).

The Wireless Home Theater
Introduced in 2014, Sharp's SD-WH1000U Blu-ray player offered the total wireless solution with WiHD wireless for video and WiSA wireless for audio. See WiSA. (Images courtesy of Sharp Electronics Corporation, www.sharpusa.com)

Furthermore, lumped R, L and C elements can be used at frequencies up to 60 GHz, if the condition that l < [lambda]/10 is satisfied, where l and [lambda] are the length of the component and the wavelength, respectively.
Moreover, the 60 GHz mmWave band is applied for wireless gigabit alliance (WiGig) along with the 2.4 GHz and 5 GHz WiFi bands, to enable high-data-rate uses.
However, for the SW with frequency f = 60 GHz, there is a relatively large skyrmion motion in the same direction of the SW propagation, and the skyrmion remains intact during its interactions with SWs.
And since 60 GHz is--compared to many other radio frequencies--safer within sensitive environments such as airports, LightPointe's 60 GHz AireLink radios help avoid RF interference and congestion issues.
He said Wi-Fi and femtocells will play a role in data-traffic offloading--describing LTE-M, NB-IoT, and 5G New Radio with massive MIMO as "more cellular," while Wi-Fi, Sigfox, 802.11p, and Lora constitute "more than cellular." He described several Leti projects, including a 6-GHz front-end module integrating PA, LNA, switch, and diplexer in RF SOI 130-nm LDMOS technology; an ultra-narrowband transceiver for the low-power wide-area Sigfox network; and a contactless connector operating at 60 GHz.
