EKI-6311GN-User_Manual V2.1 Page 28HT ProtectEnable HT (High Throughput) protect to ensure HT transmission with MAC mechanism. Under802.11n mode, wireless client can be divided into HT STA and Non-HT STA, among which theone with HT protect enabled gets higher throughput.• STA stands for Station which is referred to wireless clients connecting to Access Point.Frequency/ChannelChannel varies much as the available band differs from country to country. Select a properoperating channel in the drop-down list according to your situation.Extension ChannelOnly applicable to AP, AP Repeater, and 40MHz channel width indicates the use of channelbonding that allows the EKI-6311GN to use two channels at once. Two options are available:Upper Channel and Lower Channel.Channel ModeFour levels are available: 5MHz, 10MHz, 20MHz and 40MHz. The last one can enhance datathroughput, but it takes more bandwidth, thus it might cause potential interference.AntennaBy default, EKI-6311GN uses its built-in antenna for directional transmission; however, if youprefer to use an external antenna for your case-dependent applications, you can switch from“Internal (8 dBi)” to ”External (N-Type)”.When External (N-Type) is selected, an Antenna Gain bar will appear to allow you specify thegain of the external antenna. The antenna gain calculates the TX power back off needed toremain in compliance with regulations.You are able to choose “External (N-Type)” only when you have well done installingthe external antenna; otherwise, it might damage EKI-6311GN itself.The maximum output power will vary depending on the country selected in order tocomply with the local regulation.The output power here is counted from the RF single chain only not including the 8dBiinternal antenna.Maximum Output Power (per chain):Specify the signal transmission power. The higher the output power is, the wider the signal cancover, but the power consumption will be greater accordingly.Data RateUsually “Auto” is preferred. Under this rate, the EKI-6311GN will automatically select the highestavailable rate to transmit. In some cases, however, like where there is no great demand forspeed, you can have a relatively-low transmit rate for compromise of a long distance.Note:Note:
