We all know that we need more bandwidth now, than we ever did in the past. There tons more online games, online movies, online collab work, you name it. And the past standards of Wifi namely 802.11a, 802.11b, 802.11g, 802.11n, and so on) were getting better and better; however, the 802.11ac does the trick. Well, atleast for now it is, until something better comes along.
So what's the big difference with 802.11ac?
Key Advantages of 802.11ac:
Gigabit Speeds - 3 times the speed of 802.11n
Better Range - Whole home coverage with fewer dead spots
More Reliable - Ideal for media streaming
Ideal for Mobile - More WiFi bandwidth on your mobile devices
Compatibility - Backward compatible with 802.11a and 802.11n at 5GHz band
When you'll read the box of any 802.11ac router, you'll more likely get fluff info like: 802.11ac enables dramatic leaps forward in the speed, reliability, and quality of wireless communications. By providing wider frequency bands, 802.11ac doubles the capacity of traffic that can be processed; multiple antennas increase the reach and the quality of reception at further distances; and faster processing provides up to triple the speeds that are possible with previous standards.
They'll use all the words in the dictionary to come up with keywords like: Leaps, speed, quality, capacity, reach, reception...all the words that have no specifics to be judged with facts. Here is the key feature that we noticed, beamforming technology.
What is Beamforming Technology?
We picked up this definition from Webopedia: In aeroacoustics, beamforming is a signal processing technology that is used to direct the reception or transmission (the signal energy) on a transducer array in a chosen angular direction. Beamforming concentrates the array to sounds coming from only one particular direction to listen to sounds in one direction and ignore sounds in other directions. Beamforming is one of several technologies, as well as smart antennas and MIMO, that is used boost the range and capacity of WiMAX by providing a better signal-to-noise (SNR) ratio.
