🐘 Wifi 20Mhz Vs 40Mhz

A partir de la llegada de WiFi N, en la mayoría de routers de nueva fabricación además de la opción de elegir el número de canal surgió la posibilidad de seleccionar que el ancho de banda utilizado en esa banda de 2,4 GHz fuera de 40 MHz en lugar de los básicos 20 MHz.De esta forma ocupamos dos canales consecutivos en vez de uno y es posible lograr teóricamente duplicar el espectro If there wasn't any interference from outside sources there won't be any difference in the receivability. 20 MHz is better if the wireless network is congested. If it isn't use 80 or let your router decide. I was thinking of using channel 165 for an outdoor AP because most of the 5ghz band is congested except for 165. For 2.4Ghz stick to 20MHz channels on 1,6,11 only. If you're in a country that allows above 11 you may have more options but channel 2/4 will overlap and cause more interference. Generally it's recommended not to use auto channel selection. For 5GHz, use wider channels and use that for higher bandwidth applications/devices. In most populated areas you shouldn't set 2.4ghz higher than 20mhz. You shouldn't use channels that overlap. In the US in most cases you only want channel 1,6 or 11. Cisco When and How to Use 20mhz vs 40mhz vs 80mhz When and How to Use 20mhz vs 40mhz vs 80mhz The word network is a simple word of seven letters, but is it that simple? Let's take a broader look to understand it rightly. If putting it simply, whenever we think of or talk about some inter-connected stuff or location, we refer it as a network. Por otro lado, el ancho de banda de 40 MHz permite una velocidad de transferencia de datos de hasta 300 Mbps. Esto es el doble de la velocidad que se puede obtener con 20 MHz. Sin embargo, el uso de una banda de 40 MHz también puede tener algunas desventajas. En primer lugar, puede causar interferencia con otras redes Wi-Fi cercanas. First read Basic Wireless Settings. 20MHz vs 40MHz. The N spec is able to use 40MHz of bandwidth for increased data rates, but to maintain compatibility with legacy systems, it requires one main 20MHz channel plus a free adjacent channel at ±20MHz. The main channel is used for legacy (a/b/g) or other clients that aren't able to transmit at 40MHz. ^A In the 2.4 GHz bands bonded 40 MHz channels are uniquely named by the primary and secondary 20 MHz channels, e.g. 9+13. In the 5 GHz bands they are denoted by the center of the wider band and the primary 20 MHz channel e.g. 42[40] ^B In the US, 802.11 operation on channels 12 and 13 is allowed under low power conditions.
