According to foreign media reports, with the increasing number of new mobile devices accessing corporate infrastructure, corporate wireless networks are under increasing pressure.
According to Gartner's data, more than half of mobile data is now being transmitted over Wi-Fi and is expected to soar from 52 million terabytes in 2015 to 133 million terabytes in 2018.
To help businesses meet these challenges, IT professionals need to take note of some important trends.
Ryan Orsi, director of strategic alliances at WatchGuard, said the convergence of Wi-Fi and security will start to be managed as a separate unit in the business from 2017 onwards.
He pointed out that companies have implemented employee-facing mobility plans, and in distributed enterprises, providing Wi-Fi services to customers or the public is a must-have and gaining a competitive advantage.
"Mobility is no longer just a means of freeing people from their desks, but is also a strategy to apply network access and wireless LAN (WLAN) security policies to such traffic," he said.
To that end, network and security teams within the enterprise will share information more frequently. Orsi said he sees wireless intrusion prevention systems (WIPS) as one of the main functions of access points (APs), which has triggered a strong convergence.
He added: "Security teams need to know about malicious access points, honeypots, and Wi-Fi wireless intrusion prevention systems that are detecting double-sided demonic activity that, in turn, can prevent malicious or, if wireless intrusion prevention system sensors, automate prevention Unauthorized traffic, then the network team's work will be easier.

802.11ac Wave 2 standard
Neil Anderson, manager of Mobile and Access Solutions Business Unit at World Wide Technology, said that the advent of the wireless standard 802.11ac Wave 2 is expected to benefit many customers. The Wi-Fi guarantee is also essential.
He pointed out that 802.11ac Wave 2 has "a significant impact on the wireless network performance and data throughput that users will be aware of." Features including multi-user Multiple Input Multiple Output (MU-MIMO) also allow more devices to communicate with one access point at a time.
Anderson said: "Only this one feature can improve performance four times, and provide users with a better experience."
Orsi said that companies have begun to adopt the 802.11ac Wave 2 standard, many big-name smartphones early adoption of this standard to improve the quality of customer experience.
"Multiple-user multiple-input multiple-output is one of the main reasons why access points can communicate with multiple client devices at the same time to make more efficient use of talk time," he said.
He added that access points using the 802.11ac Wave 2 standard are starting to become the de facto standard for the enterprise, and the path to future upgrades is 802.11ax, which reduces channel conflicts by embracing cellular carriers' years of hands-on experience.
Anderson added Wi-Fi promises to address a problematic area in wireless LANs to troubleshoot and respond to user problems when connectivity is difficult or without a good experience.
He said: "From the user's perspective, tools to proactively measure Wi-Fi coverage and real-time experience are emerging."
He added that the rise of both technologies is due to the fact that the workplace is using Wi-Fi as its primary network.
Anderson points out that "offices are disappearing and employees want to work where they like to be in the same shape they love, which means IT needs to re-examine Wi-Fi - whether it's ready for a complete mobile office space Ready? Can it support wireless voice and video calls and is it known or resolved in time?
802.11ad - Bluetooth enhanced version
Dirk Gates, founder of high-performance wireless network provider Xirrus, said 802.11ad is also an interesting emerging technology. It uses the 60GHz Industrial, Scientific and Medical Radio (ISM) band instead of the 5GHz and 2.4GHz currently used by most Wi-Fi hardware.
In addition, the technology also has a theoretical maximum speed of 7Gbps, compared to only 3.2Gbps for 802.11ac Wave 2. However, as with all radios, the higher the hertz, the shorter the propagation distance.
Gates said: "You can think of it as an enhanced version of Bluetooth.It can be used for video / monitor connections, docking stations and mobile devices, just as Bluetooth in the audio connection: to provide short-range (within 10 meters Wireless connection. "
