Cellular Network Increased Traffic Gives way to MIMO Wi-Fi Technology in Smartphones

With strained cellular networks by data traffic generated by smartphones, wireless operators are trying to offload traffic to Wi-Fi networks by using next-generation 802.11 2x2 Multiple-In Multiple-Out (MIMO) technology, according to IHS.

MIMO technology uses multiple antennae at both the transmitter and receiver ends for better communication range and performance between devices. Smartphone equipment manufacturers (OEMs) are moving to 2x2 MIMO technology, with two transmitter antennae and two receiver antennae. The capabilities make Wi-Fi a suitable alternative to 3G and 4G wireless networks.

The MIMO technology is large enough even for smartphones alone, with shipments of smartphones crossing one billion units in 2013. It is estimated to be almost double to 1.9 billion in 2018, and a total of 96 percent of all mobile handsets in 2018 will support Wi-Fi and Bluetooth, according to IHS.

"With shipments of its Galaxy S5 starting last month, Samsung Electronics became the first company to offer a Smartphone that supports 802.11 2x2 MIMO," commented Stephanie Gibbons, senior connectivity analyst for IHS.

"Other handset OEMs are expected to follow Samsung's lead, due to a growing need for better-performing Wi-Fi in smartphones, in order to supplement cellular networks," adds Gibbons.

HIS also reported that while MIMO technology is just picking up for smartphones, the prospects for increasing Wi-Fi adoption is huge. Global shipments of Wi-Fi-enabled devices is expected to rise to 3.5 billion units in 2018, up from 2.2 billion in 2013, with products like cell phones, tablets, desktops, mobile PCs, home consumer electronic devices, portable consumer electronic devices, and automotive infotainment systems.
