Yet the rosiest predictions of revolutionary change in what enterprise Wi-Fi is capable of are still a bit farther off than 2020, according to industry experts. + +The crux of the matter is that, while access points with 802.11ax’s Wi-Fi 6 branding will steadily move into enterprise deployments in, the broader Wi-Fi ecosystem will not be dominated by the new standard for several years, according to Farpoint Group principal Craig Mathias. + +[[Get regularly scheduled insights by signing up for Network World newsletters.]][1] [][2] + +“Keep in mind, we’ve got lots and lots of people that are still in the middle of deploying [802.11]ac,” he said, referring to the previous top-end Wi-Fi standard. The deployment of 802.11ax will tend to follow the same pattern as the deployment of 802.11ac and, indeed, most [previous new Wi-Fi standards][3]. The most common scenario will be businesses waiting for a refresh cycle, testing the new technology and then rolling it out. + +[][4] + +BrandPost Sponsored by HPE + +[Take the Intelligent Route with Consumption-Based Storage][4] + +Combine the agility and economics of HPE storage with HPE GreenLake and run your IT department with efficiency. + +In the near term, enterprises installing 802.11ax access points will bring performance increases – the system’s [MU-MIMO][5] antenna technology is more advanced than that present in previous versions of the Wi-Fi standard, and better suited to high-density environments with large numbers of endpoints connecting at the same time. Yet those increases will be small compared to those that will ensue once 802.11ax endpoints – that is, phones, tablets, computers and more specialized devices like [IoT][6] sensors and medical devices – hit the market. + +That, unfortunately, is still some way off, and Mathias said it will take around five years for 802.11ax to become ubiquitous. + +Advertisement + +“We’re not expecting a lot of [802.11]ax devices for a while,” he said. + +Making sure devices are compliant with modern Wi-Fi standards will be crucial in the future, though it shouldn’t be a serious issue that requires a lot of device replacement outside of fields that are using some of the aforementioned specialized endpoints, like medicine. Healthcare, heavy industry and the utility sector all have much longer-than-average expected device lifespans, which means that some may still be on 802.11ac. + +That’s bad, both in terms of security and throughput, but according to Shrihari Pandit, CEO of Stealth Communications, a fiber ISP based in New York, 802.11ax access points could still prove an advantage in those settings thanks to the technology that underpins them. + +“Wi-Fi 6 devices have eight radios inside them,” he said. “MIMO and beamforming will still mean a performance upgrade, since they’ll handle multiple connections more smoothly.” + +A critical point is that some connected devices on even older 802.11 versions – n, g, and even b in some cases – won’t be able to benefit from the numerous technological upsides of the new standard. Making sure that a given network is completely cross-compatible will be a central issue for IT staff looking to realize performance gains on networks that service legacy gear.” + +Pandit said that, increasingly, data-hungry customers like tech companies are looking to 802.11ax to act as a wireline replacement for those settings. “Lots of the tech companies we service here, some of them want Wi-Fi 6 so that they can use gigabit performance without having to run wires,” he said. + +Whether it goes by Wi-Fi 6 or 802.11ax, the next generation of Wi-Fi technology is likely to be marketed a bit differently than new Wi-Fi standards have been in the past, according to Mathias. It’s less about the mere fact that there’s a new Wi-Fi standard providing faster connectivity, and more about enabling new functionality that 802.11ax makes possible, including better handling of IoT devices and integration with AI/machine learning systems. + +Luckily, prices for top-end Wi-Fi equipment shouldn’t change much compared to the current top of the line, making it easy for almost any organization to budget for the switch. + +“We’re not expecting anyone to pay a premium for [802.11ax],” said Mathias. + +**Now see ["How to determine if Wi-Fi 6 is right for you"][2]** + +Join the Network World communities on [Facebook][7] and [LinkedIn][8] to comment on topics that are top of mind. + +-------------------------------------------------------------------------------- + +via: https://www.networkworld.com/article/3512153/wi-fi-6-will-slowly-gather-steam-in-2020.html + +作者：[Jon Gold][a] +选题：[lujun9972][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://www.networkworld.com/author/Jon-Gold/ +[b]: https://github.com/lujun9972 +[1]: https://www.networkworld.com/newsletters/signup.html +[2]: https://www.networkworld.com/article/3356838/how-to-determine-if-wi-fi-6-is-right-for-you.html +[3]: https://www.networkworld.com/article/3238664/80211-wi-fi-standards-and-speeds-explained.html +[4]: https://www.networkworld.com/article/3440100/take-the-intelligent-route-with-consumption-based-storage.html?utm_source=IDG&utm_medium=promotions&utm_campaign=HPE21620&utm_content=sidebar ( Take the Intelligent Route with Consumption-Based Storage) +[5]: https://www.networkworld.com/article/3256905/13-things-you-need-to-know-about-mu-mimo-wi-fi.html +[6]: https://www.networkworld.com/article/3207535/what-is-iot-the-internet-of-things-explained.html +[7]: https://www.facebook.com/NetworkWorld/ +[8]: https://www.linkedin.com/company/network-world
