Common WLAN components

8

Common WLAN components include the following:
- Power splitter: splits one channel of signals into two or more channels with equal power.
- Coupler: divides a signal on an input port into uneven signals on two output ports.
- Attenuator/Load: reduces the amplitude or power of a signal to make the input signal to reach a secure or an ideal level. The load is a special attenuator with unlimited attenuation. The load connects to the unused output radio port, preventing radio interference.
- Combiner: combines radio signals of multiple systems and distributes receive signals over one channel to ports of each system without interference. Combiners are classified into single-band combiners and multiple-channel combiners.
- Connector: N-type and SMA connector
- Protection components: surge protector, outdoor optical fiber tube, ground cable, and waterproof tape
