According to results published in the International Data Corporation (IDC) Worldwide Quarterly WLAN Tracker, the enterprise segment grew 2.6% year over year in 2Q18 to $1.5 billion. 

Continued demand for network refreshes, digital transformation (DX) initiatives, and increased reliance on wireless networks for engaging with customers are positive indicators for continued growth in the second half of 2018.

The 802.11ac standard now accounts for 85.2% of dependent access point unit shipments in the enterprise segment and 94.5% of dependent access point revenues, marking this standard's full penetration into the market. Beginning late in 2018 and early in 2019, the market will begin to shift toward adoption of the new 802.11ax standard.

Meanwhile, consumer WLAN market revenue increased slightly, up 0.8% in 2Q18 compared to a year earlier, finishing at $1.0 billion.
