Super Fast Wi-Fi!
This entry was posted on Thursday, January 5, 2012.
With speeds reaching up to 1.3 Gbps (Gigabits-per-second), Broadcom has announced the release of their super fast Wi-Fi chips - the fastest up to date. Expected to be released in the second quarter of this year, the Wi-Fi chips are said to be many times faster than their existing counterparts. It comes as no surprise then, that these chips are being termed as '5G chips'.
The technology behind the 5G Wi-Fi chips will be displayed at the Consumer Electronics Show (CES) 2012, which is to be held next week in Las Vegas. The technology is based on the 802.11ac protocol which is indeed, the fifth generation of Wi-Fi standards. 802.11ac is the next generation of WiFi which works in 5GHz frequency band of the radio spectrum just like 802.11a and n. It is considerably faster because the wider band of 80MHz, instead of 40MHz used in the previous generation protocols. Also, the modulation technique used is 256-QAM (Quadrature Amplitude Modulation) which replaces the old 64-QAM modulation scheme. Furthermore, multiple antennae are used with MIMO technology which makes 5G Wi-Fi three times faster than its previous technology.
The technology is needed because more and more consumers are wirelessly playing multi-player games and looking to expand their gaming experience. With 5G Wi-Fi, users will be able to sync video files wirelessly and play more and more games. They will also be able to surf the internet for longer time periods, without affecting the battery life of their cell phones much.
The name '5G Wi-Fi' is being used in marketing this technology because if the word Wi-Fi is not attached to the 5th generation standard, there will be a lot of confusion between the 5G Wi-Fi standard and the 5G mobile phone protocol, which hasn't debuted yet. Thus, to avoid this confusion, the word Wi-Fi is attached to the 5G.
We can't wait!
