which is better bandwidth 20mhz or 40mhz

0609-2011 05:52 PM. Hi Ernest, based on my understanding, "Auto" will try to negotiate @ 40MHz which will have better signal quality for N since it's using 5GHz frequency, while 20MHz is using 2.4GHz, lower frequency is susceptible to common device interference. Community support is provided during standard business hours (Monday to Friday 7AM Wecan also change channel's width - it can be either 20MHz or 40MHz. Channel's width can be imagined as a width of swimming area used by a swimmer . To illustrate: if our router is set to work on channel 1 and the channel's width is set to 40MHz, it behaves like a swimmer who uses two swimming lanes in the same time - he can either Inthe US, the 2.4 GHz band includes 11 usable 20MHz channels (from 1 to 11) and has been that way since the birth of Wi-Fi. Things are simple in this band. The 2.4GHz band uses channels of 20MHz or 40MHz width. The wider the width, the fewer channels you can get out of the frequency -- the entire band is only so wide. Bandsvs Channels vs Streams. Wi-Fi uses three frequency bands, including 2.4GHz, 5GHz, and 6GHz.. Each band has multiple channels of different widths, including 20MHz, 40MHz, 80MHz, 160Mhz, and even wider. The wider a channel is, the more bandwidth it has. Data moves wirelessly via streams, including dual-stream (2x2), three-stream (3x3), quad-stream (4x4), and even more. Whatis 20mhz 40MHz coexistence? 20/40 MHz Coexistence is a feature available only in 2.4 GHz and not 5 GHz because 5 GHz has 45 channels, 24 of which do not overlap. As a result, the interference from devices in the neighboring channels would be less in 5 GHz since all the devices are spread evenly throughout the network. What is 20MHz bandwidth?
