Channel allocation schemes - Wikipedia

The objective is to achieve maximum system spectral efficiency in bit/s/Hz/site by means of frequency reuse, but still assure a certain grade of service by avoiding co-channel interference and adjacent channel interference among nearby cells or networks that share the bandwidth. Channel-allocation schemes follow one of two types of strategy:

How to: Minimize 802.11 Interference Issues

Other wireless LANs, such as one that your neighbor may be operating, can cause interference unless you coordinate the selection of 2.4GHz channels. Take action to avoid RF interference . The following are tips you should consider for reducing RF interference issues: 1. Analyze the potential for RF interference.

How to Find the Best Wi-Fi Channel for Your Router on Any ...

Jun 12, 2019 · This often has to do with the Wi-Fi channels in your area. If you're on the same Wi-Fi channel as a lot of your neighbors, you'll experience a lot of interference with their networks—so it's best to choose a different channel with fewer people on it. When you do, you'll reduce that interference and improve your WI-Fi signal.

802.11ac Channel Planning — Revolution Wi-Fi

Mar 20, 2013 · Luckily, the engineers designing 802.11ac learned from 802.11n's shortcomings and devised a clever method to minimize co-channel interference through per-frame channel width adaptation and the designation of primary channels. This presents a fundamental shift in how administrators should approach WLAN channel planning.

Change Your Wi-Fi Channel Number to Avoid Interference

Channel 1 uses the lowest frequency band and each subsequent channel increases the frequency slightly. Therefore, the further apart two channel numbers are, the less the degree of overlap and likelihood of interference. If encountering interference with a neighbor's WLAN, change to a more distant channel.

How to: Assign 802.11b/g Access Point Channels

As a design rule, access points within range of each other should be set to channel frequencies with minimal signal overlap. Otherwise, you'll find that roaming doesn't work well, and performance will degrade because of interference between access points. The 802.11b/g standards define a total of 14 frequency channels within the 2.4 GHz band.

What if a channel I want to use has too much interference? Unfortunately, you can't completely avoid interference just by using other channels. Wireless protocols 802.11b and 11g only have three non-overlapping channels. When four or more channels are used in the same area, the level of interference can increase notably.
