Gigabit Wi-Fi at last? 802.11ac "wave 2" arrives

Quote:
My first "Wi-Fi" experience was in the 80s when I used a microwave dish to send a T1, 1.544 Mbps, connection from one building to another at NASA's Goddard Space Flight Center. We've come a long way since then. But, even with 802.11ac, we've yet to crack the 1 Gigabit per second wall. Now, with the just standardized 802.11ac wave 2, we may finally break the Gbps barrier.

Sure, in a lab you can't already get 1 Gbps speeds. But most of us don't work in labs. We work in the real world.

The best performance I've ever seen using my Linksys EA9200 tri-band router with a Broadcom 5G XStream Wi-Fi chip and the latest firmware is 700Mbps. Good, but not as good as the Gigabit throughput I get over the wire off my Netgear ProSAFE Gigabit switches.

802.11ac wave 2 looks like it might set a new speed record. Wave 2 brings to the table the following features, according to the Wi-Fi Alliance:
  • MU-MIMO: Networks with MU-MIMO are capable of multitasking by sending data to multiple devices at once rather than one-at-a-time, improving overall network efficiency and throughput
  • 160 MHz channels: 802.11ac wave 2 increases the maximum channel bandwidth from 80 MHz channels to 160 MHz channels, potentially doubling transmission speeds
  • Four spatial streams: Device speeds are proportional to the number of spatial streams. Wi-Fi CERTIFIED ac now includes support for four spatial streams, up from three spatial streams.
  • Extended 5 GHz channel support: 802.11ac wave 2 encourages device support for a greater number of available channels in 5 GHz. Support for additional channels makes more efficient use of available spectrum and reduces interference and congestion by minimizing the number of networks operating on overlapping channels.

I heard that we don't really need to upgrade the hardware. It's a new update of firmware and we will getting a faster speed.
