How sweet would it be to live in a wireless home? Imagine all your computer peripherals having a proximity sensor that ID each other and interact in a seamless configuration. We are almost there. Bluetooth was the beginning, WiFi next and now we have wireless HDMI, wireless USB and some other great technology that is gathering enough momentum to reach reality very soon.
At the beginning, it had a terrible range, but the technology has improved considerable, that several manufacturers have been using it to built inexpensive video streaming solutions. You are now able to stream Internet video, from your laptop to your TV in the same room. There are devices, like the Veebeam HD that uses HDMI and a resolution of 1080p.
This is a new Wireless Display technology, that is sure to revolutionize the way we connect display devices. Sony, Dell, Toshiba and Asus, are already embracing the new standard and since WIDI can be incorporated inside Intel's new chips, it doesn't require a USB dongle to transmit. It still requires a set-top box in order to achieve connection.
The future of tri-band routers is this. Working on the 2.4, 5 and 60 GHz frequencies simultaneously, they will be really good in short range coverage. The use of repeaters could help on the 60GHz signal spectrum, which can deliver data transfer of up to 7Gb/s. We are going to start seeing these devices in a couple of years.
This technology is promoted by the WiFi alliance. Right now, a typical wireless network, rely on a connection of the client and the access point (router). WiFi Direct envisions products and devices that have embedded software access point that would enable casual formation of an ad-hoc network. This would enable the device to establish a wireless connection without involving your router or granting access to the rest of the network.
