5 Things to Know About Today's WiFi

Nearly 70% of WiFi devices sold this year will support 5GHz dual-band WiFi, surpassing the number of single-band 2.4Ghz devices in use, according to a new study from ABI Research.

The ABI Research study, commissioned by the Wi-Fi Alliance , found that widespread adoption of smartphones, tablets and consumer electronics that include support for 802.11ac WiFi in the 5GHz bands is taking dual-band WiFi mainstream. ABI says that GHz usage will grow close to 100% saturation in the next five years.

The Alliance calls this latest generation of unlicensed spectrum use Wi-Fi Certified ac, and says it offers more bandwidth for gigabit per second data rates and double the network capacity. (See Qualcomm Advances WiFi With MIMO.)
