High speed communication was enabled than conventional standard by adopting latest standard 11ac.
Of a great number of people who were not able to do it in conventional standard and large-capacity contents wirelessly transmitting is enabled.
11ac is kind of wireless LAN standard that American society called IEEE established. It is called "IEEE 802 .11ac" formally. We use only 5GHz obi without using frequency 2.4GHz band used in Wi-Fi conventionally in 11ac. In addition, we detect electric wave interference in transmitting side, sink both sides and realize stable high speed communication by technique to use vacant channel automatically.
|Frequency band||The biggest communication speed||Commentary|
|Only using 5GHz obi, it is the latest standard that realized super-high-speed communication by adoption of modulation technique (256QAM) which can transmit communication (MIMO) using plural antennas and more data.|
|We correspond to 2.4GHz, both 5GHz zones. We improve speed in comparison with previous standard by techniques such as communication (MIMO) using plural antennas.|
|11a||5GHz||54Mbps||There seem to be actually many cases that are faster than 11 g to use 5GHz obi resisting electric wave interference even if maximum velocity is the same.|
|11 g||2.4GHz||54Mbps||As 2.4GHz band is easy to go around obstacle, it is Features that electric wave is easy to arrive far.|
|11b||2.4GHz||11Mbps||It is old standard established in 1999.|
Of a great number of people whom it was not possible for in conventional standard while radio equipment of high function increased with high resolution called tablet and smartphone, and scale of contents grew big and macroscale contents wirelessly transmitting is enabled.
By MU-MIMO technology, increase of bandwidth, multi-digitizing of modulation technique, multiplexing of frame, we realize speedup that is larger than standard conventionally.
11ac realizes super-high-speed communication of approximately 2.8 times (in the case of standard maximum) in comparison with standard conventionally.
"11ac" is 1Gbps ※It is next-generation format to realize wireless communication across this. Super-high-speed Wi-Fi communication is enabled in house. Furthermore, up, several apparatuses largely use at the same time (as for conventional standard 11n/a/g/b deployment apparatus), and amount of information that we can transfer is allowed.
※The speed is a value of standard, and the actual speed depends on the environment.
※In the case of 11ac 3x3 MIMO
