The Future of 802.11ac

CowboyRobot writes "The 802.11ac standard is expected to be ratified in 2013 and NetworkComputing has an interview with representatives of Cisco Systems and Aerohive Networks about what that will mean for everyone else. 'Out of the gate, the increases in performance over 11n will not be tremendously impressive. The second wave--which will require a hardware refresh--gets far more interesting... First-generation 802.11ac products will achieve up to 1.3 Gbps through the use of three spatial streams, 80-MHz-wide channels (double the largest 40 MHz channel width with 802.11n), and use of better hardware components that allow higher levels of modulation and encoding (up to 256-QAM). Whether we will actually see 802.11ac products capable of 6.9 Gbps is dependent on hardware enhancements on both the access point and client that are not certain.'"

  1. Congestion & old nets = little benefit by phayes · · Score: 5, Insightful

    802.11ac isn't out yet but I have little hope of it really helping. I live in an apartment building I can already see 50+ routers on 2.4 & 10+ ON 5GH.

    I just don't see that much of a benefit unless the congestion avoidance is really better than 102.11n.

    Remember that 5Ghz has a much shorter range than 2.4Ghz so the problems with traffic congestion won't be as bad. If all of your neighbours switched to 5Ghz, you'd still see a noticeable real-world improvement over 2.4Ghz.

    Shorter range is a significant advantage today because it reduces interference.

    Interference is probably the main reason for lack of speed and reliability in modern city apartment WiFi.
