The subsequent frontier for instant LANs is 802.11ac, a regular that raises throughput past one gigabit in line with moment. This concise consultant presents in-depth details that can assist you plan for 802.11ac, with technical information on layout, community operations, deployment, and monitoring.
Author Matthew Gast—an specialist who led the improvement of 802.11-2012 and protection activity teams on the wireless Alliance—explains how 802.11ac won't in basic terms bring up the rate of your community, yet its ability to boot. even if you must serve extra consumers along with your present point of throughput, or serve your present consumer load with greater throughput, 802.11ac is the answer. This e-book will get you started.

11ac can transmit a single spatial stream in a 20 MHz channel, and the speed of that single spatial stream can be related to many higher data rates through simple mathematical operations. Each spatial stream adds proportionally to through‐ put. Wider channels also increase throughput proportionally. To get the speed of any MCS rate, take the basic 20 MHz stream, multiply by the number of spatial streams, and then multiply that result by a channel correction factor. Table 2-4 shows how the cal‐ culation works.
It contains the following fields: Rx and Tx VHT-MCS Map (16 bits each) The MCS map is a simple structure. Two bits are used to represent three options: the value 0 stands for the mandatory minimum support of MCS 0 through 7, the value of 1 adds MCS 8 for a total support of MCS 0 through 8, and the value of 2 42 | Chapter 3: The MAC adds MCS 9 for total support of MCS 0 through 9. The value of 3 is reserved. The two-bit field repeats eight times so that the transmitter can specify the maximum MCS supported for each spatial stream.
