Qualcomm Introduces 802.11ac Wi-Fi with Multi-user MIMO to Triple Network and Device Performance and Efficiency

MU-MIMO is a revolutionary new way for Wi-Fi networks to operate. With standard Wi-Fi, clients are served sequentially; during this time, only one device is sending and receiving information, thus only a small portion of network capacity is being used. The accumulation of these sequential events creates a drop in throughput and capacity as more devices join the network. This situation can be further exacerbated when combined with the growing amount of on-demand high resolution video content. MU-MIMO enables simultaneous transmission to groups of clients, making more efficient use of available Wi-Fi network capacity and speeding up transmissions.

“Great connectivity is not just about increasing the absolute speed. It’s about making better use of network and airtime efficiency to support the growing number of connected devices, services and applications,” said Dan Rabinovitsj, senior vice president, Qualcomm Atheros, Inc. “After seven years of MU-MIMO development and testing, we’ve gained a deep understanding of real-world channel behavior with this advanced Wi-Fi technology in crowded environments. These insights have led to the creation of our precision-based algorithm technology that, along with technologies like the Qualcomm Internet Processor and StreamBoost™, maximizes Wi-Fi performance for all connected devices.”

“The ever-increasing number of connected devices in homes and businesses require sufficient bandwidth to provide the best experience for users,” said Patrick Lo, chief executive officer, NETGEAR. “MU-MIMO, as the next logical step in the 802.11ac evolution, fulfills this need, and Qualcomm Atheros’ early provisioning of this technology is timely.”

Qualcomm Atheros pioneered MU-MIMO and created highly sophisticated algorithms that manage the complexities of simultaneous connections to optimize the experience for all devices on a VIVE 11ac network. With a more precise view of the environment, Qualcomm Atheros’ algorithm-based technology is designed to dynamically adapt to changes in channel conditions, device movement and application requirements to maximize throughput and device performance. This not only makes the best use of the available bandwidth, but also maintains better connections in complex multi-user networks.
