各个地区2.4G及5G信道一览表 美洲（FCC） 2.412 ~ 2.462 GHz：11个信道 5.15 ~ 5.35 GHz，5.725 ~ 5.825 GHz；12个信道 中国 2.412 ~ 2.472 GHz：13个信道 5.725 ~ 5.825 GHz：4个信道 ETSI 2.412 ~ 2.472 GHz：13个信道 5.15 ~ 5.35 GHz：8个信道5470 ~ 5725 MHz：11个信道 以色列 2.432 ~ 2.472 GHz：9个信道 5.15 ~ 5.35 GHz：8个信道 日本 2.412 ~ 2.472 GHz：13个信道（OFDM） 2.412 ~ 2.484 GHz：14个信道（CCK） 5.15 ~ 5.25 GHz：4个信道 韩国 2.412 ~ 2.472 GHz：13个信道 5.15 ~ 5.35 GHz，5.46 ~ 5.72 GHz，5.725~ 5.825 GHz：19个信道 北美洲（FCC除外） 2.412 ~ 2.462 GHz：11个信道 5.15 ~ 5.35 GHz，5.725~ 5.825 GHz：12个信道 日本2 2.412 ~ 2.472 GHz：13个信道 OFDM2.412 ~ 2.484 GHz：14个信道 CCK5.15 ~ 5.35 GHz：8个信道 新加坡 2.412 ~ 2.472 GHz：13个信道 5.15 ~ 5.35 GHz，5.725~ 5.825 GHz：12个信道 中国台湾 2.412 ~ 2.462 GHz：11个信道 5.25 ~ 5.35 GHz，5.725~ 5.825 GHz：7个信道 不重叠信道802.11a：12个信道 （FCC；其他法规域支持的802.11a信道数不同）FCC目前支持12个不重叠信道，根据FCC规则，有可能通过未来固件版本而支持23个信道802.11b/g：3个信道 WLAN信道列表是法律所规定的IEEE 802.11（或称为WiFi）无线网络应该使用的无线信道。 802.11工作组划分了两个独立的频段，2.4 GHz和4.9/5.8 GHz。每个频段又划分为若干信道，且每个国家自己制定政策订出如何使用这些频段。 https://blog.csdn.net/achejq/article/details/8958834 该文章末尾的List_of_WLAN_channels信息错误 最新的List_of_WLAN_channels，来自维基百科https://en.wikipedia.org/wiki/List_of_WLAN_channels //2.4 CountryRegion 5 CountryRegionABand //iwpriv ra0 set CountryRegionABand=7 function init_CountryRegion(region) { var region= parseInt(region); if(region == 0) { CHANNEL_TABLE_24G = [1,2,3,4,5,6,7,8,9,10,11]; //United States,Canada } else if(region == 1) { CHANNEL_TABLE_24G = [1,2,3,4,5,6,7,8,9,10,11,12,13]; //china australia } else if(region == 2) { CHANNEL_TABLE_24G = [10,11]; } else if(region == 3) { CHANNEL_TABLE_24G = [10,11,12,13]; } else if(region == 4) { CHANNEL_TABLE_24G = [14]; } else if(region == 5) { CHANNEL_TABLE_24G = [1,2,3,4,5,6,7,8,9,10,11,12,13,14]; } else if(region == 6) { CHANNEL_TABLE_24G = [3,4,5,6,7,8,9]; } else if(region == 7) { CHANNEL_TABLE_24G = [5,6,7,8,9,10,11,12,13]; } else { CHANNEL_TABLE_24G = [1,2,3,4,5,6,7,8,9,10,11]; //United States,Canada } } //2.4 CountryRegion 5 CountryRegionABand //iwpriv ra0 set CountryRegionABand=10 function init_CountryRegionABand(region) { var region= parseInt(region); if(region == 0) { CHANNEL_TABLE_5G = [36,40,44,48,52,56,60,64,149,153,157,161,165]; } else if(region == 1) { CHANNEL_TABLE_5G = [36,40,44,48,52,56,60,64,100,104,108,112,116,120,124,128,132,136,140]; //Europe } else if(region == 2) { CHANNEL_TABLE_5G = [36,40,44,48,52,56,60,64]; } else if(region == 3) { CHANNEL_TABLE_5G = [52,56,60,64,149,153,157,161]; } else if(region == 4) { CHANNEL_TABLE_5G = [149,153,157,161,165]; //China } else if(region == 5) { CHANNEL_TABLE_5G = [149,153,157,161]; } else if(region == 6) { CHANNEL_TABLE_5G = [36,40,44,48]; } else if(region == 7) { CHANNEL_TABLE_5G = [36,40,44,48,52,56,60,64,100,104,108,112,116,120,124,128,132,136,140,149,153,157,161,165]; //U.S.A } else if(region == 8) { CHANNEL_TABLE_5G = [52,56,60,64]; } else if(region == 9) { CHANNEL_TABLE_5G = [36,40,44,48,52,56,60,64,100,104,108,112,116,132,136,140,149,153,157,161,165]; } else if(region == 10) { CHANNEL_TABLE_5G = [36,40,44,48,149,153,157,161,165]; } else if(region == 11) { CHANNEL_TABLE_5G = [36,40,44,48,52,56,60,64,100,104,108,112,116,120,124,149,153,157,161]; } else { CHANNEL_TABLE_5G = [36,40,44,48,149,153,157,161,165]; //USA } } function init_24g_channel_select() { var index_country_region = wifi_country_region24g; if( (index_country_region != " ") && (index_country_region != undefined) ) { init_CountryRegion(index_country_region); } else { init_CountryRegion(0); //USA } var select_24g = $("#sz11gChannel"); select_24g.append('Auto'); for(var i=0; i < CHANNEL_TABLE_24G.length; i++) { var value = CHANNEL_TABLE_24G[i]; var id = "Channel" + CHANNEL_TABLE_24G[i]; var value_show ="Channel " + CHANNEL_TABLE_24G[i]; select_24g.append(''+value_show+''); } } function init_5g_channel_select() { var index_country_region = wifi_country_region5g; if( (index_country_region != " ") && (index_country_region != undefined) ) { init_CountryRegionABand(index_country_region); } else { init_CountryRegionABand(10); //USA } var select_5g = $("#sz11Channel5G"); select_5g.append('Auto'); for(var i=0; i < CHANNEL_TABLE_5G.length; i++) { var value = CHANNEL_TABLE_5G[i]; var id = "Channel" + CHANNEL_TABLE_5G[i]; var value_show ="Channel " + CHANNEL_TABLE_5G[i]; select_5g.append(''+value_show+''); } }
在openwrt中，一般修改config/wireless即可，会有脚本sh，自动设置到.dat文件里面 ./etc/wireless/mt7603e/mt7603e.dat ./etc/wireless/mt7612e/mt7612e.dat ---------------------------------------------------- root@OpenWrt:/etc# cat config/wireless ---------------------------------------------------- config wifi-device 'mt7603e' option type 'mt7603e' option vendor 'ralink' option band '2.4G' option beacon '100' option wifimode '9' option txpower '100' option channel '0' option disabled '0' option hidden '0' option wps_enabled 'enable' option wps_router_pin 'pin' option wps_mode 'PBC' option bw '1' option region '0' config wifi-iface option device 'mt7603e' option ifname 'ra0' option network 'lan' option mode 'ap' option ssid 'FURRIONAP_2660F8' option instance '1' option wmm 'enable' option encryption 'psk-mixed+ccmp' option key 'FA2660F8' config wifi-device 'mt7612e' option type 'mt7612e' option vendor 'ralink' option band '5G' option channel '0' option autoch '2' option disabled '0' option txpower '100' option hidden '0' option wifimode '14' option bw '2' option wps_enabled 'enable' option wps_router_pin 'pin' option wps_mode 'PBC' option aregion '10' config wifi-iface option device 'mt7612e' option ifname 'rai0' option network 'lan' option mode 'ap' option ssid 'FURRIONAP_5G_FFFFFF' option encryption 'psk-mixed+ccmp' option key 'FAFFFFFF' option instance '2' config wifi-device 'radio0' option type 'mac80211' option channel '0' option hwmode '11g' option htmode 'HT20' config wifi-iface option device 'radio0' option network 'wan0' option mode 'sta' option ssid 'wifi' option encryption 'psk2' option key 'wifiwifi' option ifname 'wlan0' root@OpenWrt:/etc# grep -rn "region" ./etc/config/wireless 16: option region '0' //2.4G 43: option aregion '10' //5G root@OpenWrt:/etc#配置文件在： mt7603e 2.4G mt7612e 5G CountryRegion 0 //USA 2.4G CountryRegionABand 10//USA 5G root@OpenWrt:/# grep -rn "CountryRegion" ./etc/wireless/ ./etc/wireless/mt7603e/mt7603e.dat:4:CountryRegion=0 ./etc/wireless/mt7603e/mt7603e.dat:5:CountryRegionABand=7 ./etc/wireless/mt7612e/mt7612e.dat:4:CountryRegion=1 ./etc/wireless/mt7612e/mt7612e.dat:5:CountryRegionABand=10 //get 2.4g CountryRegion memset( src_country_region24g_1, 0x0, sizeof(src_country_region24g_1)); get_system_output("uci get wireless.mt7603e.region", src_country_region24g_1, sizeof(src_country_region24g_1)); //get 5g CountryRegionABand memset(src_country_region5g_2, 0x0, sizeof(src_country_region5g_2)); get_system_output("uci get wireless.mt7612e.aregion", src_country_region5g_2, sizeof(src_country_region5g_2)); |
