How it works

How antennas work
The task of an antenna is to convert electrical current into electromagnetic waves and vice
versa. A basic distinction is made between detached and directly mounted or integrated
antennas. Detached antennas increase the reliability of wireless links by optimizing the
transmit and receive conditions because these antennas can be mounted at a location with
optimum wireless conditions. A cable connects the detached antenna and access point or
client. The antennas operated directly on the device allow compact, low-maintenance
installation.
Antennas can communicate in the 2.4 GHz or 5 GHz frequency band or in both frequency
bands.
