But without a wireless channel scanner, proper WiFi channel planning is impossible because you have no way of knowing which channels are busy and which are free from traffic. ThatвЂ™s why WiFi channel planning is so important, and why it should always precede every deployment of a WiFi network. While that may sound like a lot, only 3 of these channels are non-overlapping (1, 6, and 11), meaning theyвЂ™re not affected by co-channel interference caused by adjacent channels. In North America, there are 11 channels available. WiFi networks (those that use the 2.4 GHz band) can also take advantage of multiple lines, or channels as they are called, when broadcasting data. ThatвЂ™s why busy highways tend to have multiple lines going both ways. When too many cars travel in the same line, the speed of traffic can slow down to a crawl and make traveling anything but enjoyable. Why? Because WiFi channels are sort of like the lines on the highway. ItвЂ™s paramount that you pick a channel that isnвЂ™t already occupied by several other nearby wireless networks. One available option lets you choose which WiFi channel the router should operate on. When you received your home router from your ISP, the chances are that you werenвЂ™t paying much attention to all configuration options available. Why Do I Need to Use a Wireless Channel Scanner?
