RouterOS中wifi自动频率选择及发射功率设置
|
1. 在routeros中，wifi使用的频率设置说明
DFS的全称是Dynamic Frequency Selection，即自动频率选择，只有在DFS Mode设置为None时，Frequency才有效，此时可以手工选择频率置。否则DFS会根据一定的算法自动选择工作频率。关于DFS的具体说明如下： Controls DFS (Dynamic Frequency Selection). none - disables DFS.no-radar-detect - Select channel from scan-list with the lowest number of detected networks. In 'wds-slave' mode this setting has no effect.radar-detect - Select channel with the lowest number of detected networks and use it if no radar is detected on it for 60 seconds. Otherwise, select different channel. This setting may be required by the country regulations. This property has effect only in AP mode.
2. 发射功率的选择 发射功率的选择首先看Frequency Mode的设置：
有关该参数的设置，官方说明如下： Three frequency modes are available: regulatory-domain - Limit available channels and maximum transmit power for each channel according to the value of countrymanual-txpower - Same as above, but do not limit maximum transmit power.superchannel - Conformance Testing Mode. Allow all channels supported by the card. List of available channels for each band can be seen in /wireless info print . This mode allows you to test wireless channels outside the default scan-list and/or regulatory domain. This mode should only be used in controlled environments, or if you have a special permission to use it in your region. Before v4.3 this was called Custom Frequency Upgrade, or Superchannel. Since RouterOS v4.3 this mode is available without special key upgrades to all installations.所以，如果想简单点，就直接选择regulatory-domain，这样可用频率和发射功率都根据所选的国家自动设置。 如果想手动控制发射功率，可是选择Manual-txpower，此时，发射功率由Tx Power Mode和Tx Power两个参数决定：
有关Tx Power Mode参数的官方说明如下： sets up tx-power mode for wireless card default - use values stored in the cardcard-rates - use transmit power as defined by tx-power settingall-rated-fixed - use same transmit power for all data rates. Can damage the card if transmit power is set above rated value of the card for used ratemanual-table - define transmit power for each rate separately. Can damage the card if transmit power is set above rated value of the card for used rate.
