Download 802.11n: A Survival Guide by Matthew Gast PDF

By Matthew Gast

Instant has ultimately come of age. With an important leap in throughput over earlier criteria, 802.11n is the 1st instant expertise that doesn’t alternate pace for mobility, and clients have stormed onto instant networks with a keenness. during this concise advisor, Matthew Gast—chair of the IEEE crew that produced revision 802.11-2012—shows you why instant has develop into the default approach to connecting to a community, and gives technical information you want to plan, layout, and set up 802.11n today.

Building a community for the multitude of recent units is now a strategic selection for community engineers in every single place. This publication promises an in-depth examine key components of 802.11n, and indicates you the way to accomplish an Ethernet-free instant office.

find out how MIMO’s a number of facts streams significantly bring up instant speed
notice how 802.11n alterations enhance MAC efficiency
learn complex PHY beneficial properties akin to beanforming and space-time code block
Use complicated MAC gains to take care of interoperability with older devices
Plan an 802.11n community by means of making a choice on site visitors call for, key purposes, energy standards, and security
select the structure, decide on undefined, and plan insurance to layout and construct your network

Example text

By using a 3×3 AP, network administrators can gain extra sensitivity to decode the weak signals from even single-stream clients. Figure 2-4 shows the conceptual range increase when MRC is used. The solid line on the graph is the rate-over-range plot for reception of a two-stream device by a 2×2 MIMO system; the dashed line is the rate-over-range plot for reception of the same two-stream transmission by a 3×3 MIMO system. There is no increase in peak speed because both systems are operating as two-stream receivers.

11 association process. 11n device only transmits LDPC-encoded frames to peers that have indicated support for LDPC in either Beacon frames or Association Request frames. 4. One of the early presentations on LDPC’s coding gain is IEEE document 11-04/0071. 11 MAC was generally viewed as being about 50% efficient— take the operating data rate of the system during transmission, and cut it in half to account for the various forms of protocol overhead needed to coordinate transmissions between stations.

The Big Idea: MIMO and Data Streams | 15 Additional information from the supplemental radio chains increases the accuracy of the MRC process. 11n devices. The antennas in many battery-powered devices are designed around the device case and aesthetics, not the optimal layout for maximum radio performance. By using a 3×3 AP, network administrators can gain extra sensitivity to decode the weak signals from even single-stream clients. Figure 2-4 shows the conceptual range increase when MRC is used.
