802.11ac - CES 2015: D-Link attempts to break 1Gbps Wi-Fi speed barrier | ZDNet - 0 views
-
D-Link isn't using the current 802.11ac 2013 standard for its new line of high-speed routers; instead, it's using the latest Broadcom chipset based on the still unratified 802.11ac 2015 standard, aka Wave 2. This new wave of technology pushes the theoretical limit of Wi-Fi to 7Gbps.
-
In addition, Wave 2 supports multi-user MIMO, which enables simultaneous multiple spatial streams to multiple clients. Multi-user MIMO is seen as being as big an improvement for Wi-Fi as the jump from shared to switched Ethernet was for wired networking.
-
Multi-user MIMO, however, won't be supported in the AC3200. You'll need to wait for the next two models in this new Wi-Fi router family to appear later this year for that.

"Ever since 802.11ac started appearing in routers we've been dreaming of getting honest-to-goodness 1 Gigabit per second (Gbps) Wi-Fi speeds. Ha! The fastest 802.11ac router CNET or ZDNet has seen to date, the Asus AC2400 RT-AC87U Dual-band Wireless Gigabit Router delivers 504 Megabits per second (Mbps) to clients. D-Link's new AC3200 ULTRA Wi-Fi Router (DIR-890L/R), introduced at CES, promises to deliver speeds of up to 1.3Gbps."
