A New Wi-Fi Chip That Sends Video From Your Smartphone To The Television

For mobile users who were disillusioned with the DLNA features in their smartphones, the Wi-Fi alliance is making an alternative. It is called Miracast. The new chip is going to operate in the super fast 802.11AC mode. It will allow a smartphone or other mobile device with the Miracast feature to send video and audio to another compatible device. No router will be needed.

DLNADigital Living Network Alliance ( DLNA ) is installed on some of the more expensive smartphones of the world. It was a good idea, since it would prevent having to carry an HDMI cable around if you wanted to watch your mobile videos on a monitor or television. The problem is that it did not catch on very well with the television makers. Here we have a second chance at the matter with the new Miracast chip.

The Miracast chip uses a dual channel approach to allow a mobile device to send data to a waiting television screen. The Wi-Fi alliance is still busy writing the prerequisites for the technology, but manufacturers are already getting on board. It looks like not only monitors and television are going to be experiencing the change. Marvell, a chip maker, is planning on having this new idea work with laptops and tablets. The laptop or tablet will turn on automatically when another mobile device enters the room. This will be great for a meeting with the board, for example, where the CEO walks in and his data is immediately distributed to the board member's screens. Can you imagine playing Angry Birds on your 55 inch LG OLED TV? It would be a spectacular sight.

Gamers will be thoroughly ecstatic with the quick speeds of the new AC standard, since their games move a lot of data around. The 802.11AC standard is currently rated for 1300 mega bits per second. Compare that with the 300 mega bits per second of the 802.11N mode. That is over four times faster data rates. The routers for the AC standard are just coming to market.

The Miracast chip simply copies what is on the screen of the mobile device and sends it off to a another screen. There is no problem with codecs like the DLNA system. Whatever type of video file is playing is what will be sent off to the other screen. The Wi-Fi Alliance Wi-Fi display specification will be published in August. There may even be Miracast-ready smartphones ready by the end of the year.
