Apa perbedaan 20mhz dan 40mhz? Jadi, perbedaan antara 20 MHz dan 40 MHz adalah throughput. 40 MHz memiliki throughput yang lebih tinggi dari 20 MHz berkat ikatan saluran. Bandwidth juga diartikan sebagai luas atau lebar cakupan frekuensi yang digunakan oleh sinyal dalam medium transmisi yang dapat diartikan sebagai perbedaan antara komponen 2.4 Ghz WiFi: 20 MHz vs 40 MHz vs 80 MHz. If you're using 2.4 GHz, the answer is simple. The best bandwidth for 2.4 Ghz is 20 MHz. In the majority of cases, using wide widths on 2.4 GHz isn't worthwhile. The performance tradeoffs from interference on overlapping channels will likely outweigh the throughput benefits. If you use 802.11n with 20MHz channels, stick to channels 1, 6, and 11 -- if you want to use 40MHz channels, be aware that the airwaves might be congested, unless you live in a detached house it divides the 80 mhz bandwidth into 20 mhz chunks and center the client on one of those chunks. Same goes for if you can only do 40mhz, it does 2 chunks and centers on one of those chunks. This means there is never any overlap or interference.When the bandplan was created this was the point of grouping it the way it is. 1 80 mhz channel, = 2 I was playing with 40mhz today, but there is a MOFO sitting at channel 4+8 using 40mhz and fucking up the wifi of the whole spectrum for the rest of the neighborhood. Using 40mhz on channel 1+5 (the least congested) netted me a much worse performance than sticking to 20mhz. Z = Bandwidth 2, 4, 8 (2 = 20Mhz, 4=40Mhz, 8=80Mhz) c = b for Beamform, s for STBC, - none s = Guard Interval, indicates Short guard interval applicable over LGI (Long guard interval) If you use 40 MHz channel the max data rate will be 270 Mbps and 300 Mbps for long and short guard interval respectively. .
