Voici les meilleures bandes de canaux à utiliser : 1, 6, 11. Pour une diffusion de 40MHz avec 2,4GHz. Voici les meilleures bandes de canaux à utiliser : 3, 11. Pour une diffusion de 20MHz avec 5GHz. Vous devez utiliser une fréquence de 40MHz au lieu de 20MHz, ou utiliser une combinaison si votre appareil en a besoin et que le routeur le permet.
Wide bandwidths (40MHz & 80MHz) are achieved with bonding 2 and 4 adjacent channels together. Why it's not recommended on 2.4GHz range is simply the lack of available channels. Interference comes in 2 varieties; Wi-Fi and non-Wi-Fi. The congestion in 2.4GHz range caused taking 5GHz channels in use in the first place.
High-density Wi-Fi is a design strategy for large deployments to provide pervasive connectivity to clients when a high number of clients are expected to connect to Access Points within a small space. (some will support 20-Mhz, some will support 40-MHz and some will support 80-Mhz channels). Due to this, it is better to have each client
In a very busy/noisy environment, including when the bandwidth crowding is self-inflicted due to specific very dense AP environments, I have found that 40mhz bands or even 20mhz bands provided a better experience and provided more bandwidth than the vast majority of users ever actually tried to use day to day.
