wifi terminology explained
A router is a network appliance.
An AP and Station are RF appliances. Ubiquiti RF appliances are radios.
An AP is your “base station”. It associates with clients that are generically called CPE (customer premise equipment) radios, and in UBNT lingo they are Stations and Motorola calls them an SU (subscriber unit) radio.
A client can only connect to an AP.
If the client mode can be bridged or routed.
You will often see
“~>” is wireless and “->” is wired.
Example: AP ~> [Sta -> AP] ~> [Sta -> AP] ~> Sta
A typical customer installation might look like this
AP ~> Sta (router mode) LAN 192.168.0.1 gateway
AP ~> Stat (bridge mode) -> on site router LAN 192.168.0.1 gateway
what is AP-WDS? Access point with WDS protocol mixed in so it can share with other access points.
Explaining Data Rate:
This defines the data rate (in Mbps) at which the device should transmit wireless packets. If the Best (automatic) option is selected, then the rate algorithm will select the best data rate depending on the link quality conditions. You can fix a specific data rate between MCS 0 and MCS 7 (or MCS15 for 2×2 chains devices) also. Use Best (automatic) option if you are having trouble getting connected or losing data at a higher rate. In this case the lower data rates will be used by device automatically. If you select 20MHz Channel Spectrum width the maximum data rate is MCS7 (65Mbps) or MCS15 (150Mbps). If you select 40MHz Channel Spectrum width the maximum data rate is MCS7 (150Mbps) or MCS15 (300Mbps).
