About beamforming
Beamforming is a non-proprietary wireless technology that can be integrated across a range of devices, from access points to laptops to smartphones. It greatly improves wireless performance, providing a 2X-3X improvement over previous wireless solutions.
Beamforming enables this performance with an innovative approach to how wireless devices connect. In previous generations, wireless was like a lightbulb, with a hotspot or access point "radiating" wireless indiscriminately in a set area. Beamforming is like a laser -- the hub recognizes the device that needs wireless and focuses the wireless directly where it's needed -- whether it's one device or 20. Because of this novel approach, wireless can also beam around corners and through walls, eliminating previous performance obstacles encountered in large enterprise spaces.
In an enterprise environment, not all devices on the network need beamforming to reap the benefits of the technology. An access point with implicit beamforming technology can still directly "beamform" to an end device without it, enabling better performance. Inversely, a tablet with beamforming technology can better leverage the wireless signal from an access point that does not have beamforming.
Devices leveraging beamforming, from access points to end devices, have been shipping in volume since November 2010. As enterprise IT departments upgrade their infrastructure and invest in new equipment for employees, it will be beneficial to work with technology suppliers to ensure new investments boast beamforming technology.
Znie to velmi zaujimavo...
Som zvedavy na airbeam....ale vraj do dvoch rokov sa toho vo wireless vela zmeni....podstatne vyssia priepustnost, znizenie rusenia v prostredi(kvoli usmerneniu), lepsie SNR....
Pre tych co nevedia eng.... Doteraz ap funguju tak ze vysielaju urcitym smerom kde su namierene......prirovnali to k ziarovke - tak funguju dnesne wireless - ziarovka svieti vsade a stale...beamforming bude ako laser - kedy namieri presne na klienta.....Umozni to podstatne lepsi prechod cez stromy, steny...
Dosiahne sa to viacerymi subantenami...resp. castami, ktore budu samostatne vysielat a prijimat....zlepsenie bude aj ked bude oproti len jednoantenovy system kedze ap bude prijimat signal viacerymi subantenami....cim sa zlepsi priepustnost, signal...znizi sa pocet retries...
Testmi sa zlepsil signal pouzitim beamforming technologie o 12dB....
