802.11 ax is Wi - fi 6, the next gen wireless network standard. Read about its benefits and listen to experts discussing it via a podcast.

如果你像我一样, you’re always wondering when the best time is to buy a pc, 或者电话，或者科技小发明. 为什么? 因为当你买到最新最好的那一刻, 在newer, ), 快, 推出更高容量版本!

现实是, you will at some point need to upgrade your devices and if you’re an IT person, you’ll also need to upgrade your network to support the technology and the increasing number of varied devices taking advantage of it and the Wi-Fi it provides.

网络已经感受到了物联网带来的压力

你们的服务怎么样?? How long can you afford to wait for the next best thing just because you know t再来 will always be something even ) down the line? Your customers and staff are already pushing the limits of what your network can handle, 即使你去年才升级过. 和, 如果你的网络还没有“那么糟糕”, it will soon be as 无线局域网 radios have become so cheap that they are ending up in more and different devices that your network will end up having to support. The demand for connectivity and 无线局域网 density will bring your older 无线局域网 infrastructure to its knees.  那么，你能做些什么呢?

Wi - fi 6的救援

The latest and greatest Wi-Fi technology to be heading to market is 802.11ax，也被称为， Wi - fi 6. What the “6” means is that it is the sixth generation of Wi-Fi technology, which is a lot easier to remember than the various letters placed after 802.11!

Wi - fi 6 offers many benefits, however the most significant are:

1. 更好的raw性能. 多用户, 多个输入, multiple output (MU-MIMO) downlink/uplink and ability to scale up to eight streams help increase throughput by up to four times, and support for 1024 quadrature amplitude modulation (QAM) packs more bits further increasing capacity.

2. 更好的密集客户端环境支持 with orthogonal frequency division multiple access (OFDMA), for the massively connected world of users and the Internet of Things (IOT).

下latency which translates into ) performing 应用程序.

High density, higher throughput 应用程序 to benefit the most

Wi - fi 6 will help 应用程序 in industries that have heavy throughput demand and high-density requirements. 工业公司 such as airports w再来 you have a high volume of users passing through at any given time, whether they are using the airport as a transfer point or as a departure location, Wi-Fi access for information or entertainment to pass some time is imperative.

Additional industries include higher 教育 institutions like colleges and universities with their broad and diverse user base, 应用程序, 和设备. Healthcare is experiencing a growing need to modernize services with 物联网. 智能城市有不同的部门, 城市建筑, 每个公民都有特定的要求, 但它们都需要更好的网络性能, 名单还在继续. Any network that must provide support for high throughput 应用程序 in a high-density environment will benefit the most from Wi - fi 6.

2.4 ghz & 5 ghz deployment

我们都知道电流是2.4ghz频段仍然拥挤. 然而, Wi - fi 6 brings some relief as all major improvements of this technology such as uplink MU-MIMO, 下行μ-MIMO, OFDMA, 1024 -QAM, target wake time (TWT) and more are coming to both Wi-Fi bands. 这将显著提高2的效率.4 ghz客户端将由物联网主导.

Wi - fi 6可用吗?

记得802.11ax (Wi - fi 6)现已可用. Every network manager should start thinking about 802.11ax，特别是如果你仍然使用802.11n or if you’re considering deploying many new wireless devices or into new spaces w再来 无线局域网 will be in high demand.

啤酒如何提供帮助?

汁饮料 无线网络解决方案 are found in organisations of all sizes, from small to extra-large, in various sectors such as 政府, 医疗保健, 教育 在小学或大型大学， 运输零售，甚至公用事业. 

Many of our customers look at upgrading their Wi-Fi infrastructure every 4-5 years and with Wi - fi 6, some will begin transitioning earlier than that – at least partially, depending on areas w再来 their network is reaching capacity as well as those who simply want the latest technological advances. 在接下来的24个月里, we expect most enterprises to have some components of their infrastructure running on this newest technology.

Given that upgrading your network is not as fast as upgrading a personal device, now might be a good time to start planning your network infrastructure upgrade to Wi - fi 6 before your users and 物联网 devices bring your network to its knees.
