802.11ac 'gigabit Wi-Fi' starts to show potential, limits

Vendor tests and very early 802.11ac customers provide a reality check on "gigabit Wi-Fi" but also confirm much of its promise.Vendors have been testing their 11ac products for months, yielding data that show how 11ac performs and what variables can affect performance. Some of the tests are under ideal laboratory-style conditions; others involve actual or simulated production networks. Among the results: consistent 400M to 800Mbps throughput for 11ac clients in best-case situations, higher throughput as range increases compared to 11n, more clients serviced by each access point, and a boost in performance for existing 11n clients.Wireless LAN vendors are stepping up product introductions, and all of them are coming out with products, among them Aerohive, Aruba Networks, Cisco (including its Meraki cloud-based offering), Meru, Motorola Solutions, Ruckus, Ubiquiti, and Xirrus.The IEEE 802.11ac standard does several things to triple the throughput of 11n. It builds on some of the technolo
