2 Gartner, Mobile Device Proliferation Is Forcing Network Leaders to Redesign Enterprise Wireless LANs, 19 May 2014


Ảnh hưởng của di động đến Mạng khách hàng High volumes of mobile video can clog the airwaves

Mobile applications are more prevalent in the workplace, generating more traffic

Bring-your-own-device (BYOD) policies and mobile initiatives are increasing traffic and straining WLAN performance

Faster 802.11ac Wave 2–capable end-user devices will hit the market this year

Customers and users will still expect high-performance Wi-Fi access
