802.11ax wifi 6

Wifi 6? yes introduce new standart of wifi (wireless fidelity). Wifi 6 is next generation of wifi 5 or in standart 802.11ac. Actually knows every generation have significant improvement like throughput and some replace old technology or modified them.
Old standard 802.11ac offering theoretical maximum bandwith of 1.3 Gbps.  Unfortunately, these gains have not been enough to keep pace with demand, So will be noisy and drop in crowded place like train station or another public service.

IEEE has launch new standard that can be solution with boosting wifi performance. 802.11ax promises a fourfold increase in average throughput per user. This format also create especially for high-density public environments. 802.11ax has extended coverage and longer battery life.  802.11ax can deliver a single stream at 3.5Gbps, and with new multiplexing technology borrowed from the world of LTE cellular, can deliver four simultaneous streams to a single endpoint for a total theoretical bandwidth of an astounding 14Gbps.

How wifi 6 can Solve Problem in Crowded Place

The essential issues with Wi-Fi are that transfer speed is shared among endpoint gadgets. Access Point have coverage area that maybe overlapping with another because user can be moving among it.

Access Point before has old shared Ethernet days called Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). This technology requires all endpoint devices listen clear signal before transmittin. In the event of interference, congestion or collision, the endpoint goes into a back-off procedure, waits for the all-clear, then transmits.

As describe above we can clear that how sometime we feel. Oh God, Connection is poor. Not only in slowly transfer rate it has cost for waiting clear signal. Borrowing a trick from 4G LTE and a few earlier standards, 802.11ax adds a way to break a Wi-Fi channel down into as many as a couple thousand tightly spaced “subcarriers” or subchannels. Each of these subchannels can carry various combined payloads of data for different devices, and interference or noise in one subchannel is isolated from the rest, reducing the need to retransmit or slow down the entire conversation to a lower data rate that can be received clearly. (This tech is called Orthogonal Frequency Division Multiple Access or OFDMA.)

Huawei predicts a new standard of 802.11ax WiFi or “WiFi 6” starting to be adopted this year. The peak of commercial use is predicted in the coming 2023, with penetration rates up to 90 percent. This can not be separated from the development of the 5G network which is increasingly widespread and serious. Super fast internet connectivity is predicted to affect the industry chain and service digitalization. As a result, companies will need WiFi 6 technology to build networks with higher bandwidth.

“WiFi networks will be an important part of digital transformation. However, there will be many challenges going forward,”

Campus Network Domain President, Huawei Data Communication Product Line, Steven Zhao, on the sidelines of the “Huawei Forum”, in the Mobile World Congress series ( MWC) 2019, in Barcelona, ​​Spain

Steven Zhao then discussed trends for the next three to five years. Technologies such as 4K video, IoT, Virtual Reality, Augmented Reality, etc., require bandwidth and strong connections. In this case, a capable 5G network also needs to be accompanied by a strong WiFi 6 network to provide the best internet experience for people and businesses for various needs.
