operating channel in the drop-down list according to your situation.
Extension Channel
Only applicable to AP, AP Repeater, and 40MHz channel width) indicates the use of channel
bonding that allows the LEVELONE 150MBPS WIRELESS POE AP to use two channels at once.
Two options are available: Upper Channel and Lower Channel.
Channel Mode
Four levels are available: 5MHz, 10MHz, 20MHz and 40MHz. The last one can enhance data
throughput, but it takes more bandwidth, thus it might cause potential interference.
Antenna
By default, LEVELONE 150MBPS WIRELESS POE AP uses its built-in antenna for directional
transmission; however, if you prefer 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 the
gain of the external antenna. The antenna gain calculates the TX power back off needed to
remain in compliance with regulations.
Note:
You are able to choose "External (N-Type)" only when you have well done installing the external
antenna; otherwise, it might damage LEVELONE 150MBPS WIRELESS POE AP itself.
The maximum output power will vary depending on the country selected in order to
comply with the local regulation.
The output power here is counted from the RF single chain only not including the 8dBi
internal antenna.
Maximum Output Power (per chain):
Specify the signal transmission power. The higher the output power is, the wider the signal can
cover, but the power consumption will be greater accordingly.
Data Rate
Usually "Auto" is preferred. Under this rate, the LEVELONE 150MBPS WIRELESS POE AP will
automatically select the highest available rate to transmit. In some cases, however, like where
there is no great demand for speed, you can have a relatively-low transmit rate for compromise of
a long distance.
