Wireless repeaters are networking devices that increase the distance a wireless network reaches and improve overall wireless signal quality. A repeater expands the network range and overcomes signal obstructions by mirroring and re-broadcasting the same SSID and security settings of the original wireless network.
Wireless repeaters overcome some signal obstructions and wireless interferences. Physical objects can damage wireless signals, and certain home appliances, such as cordless phones and microwave ovens, can cause wireless interference that may make a wireless network unusable. Placing a wireless repeater in places where less objects are present allows the signal to travel through a cleaner path, which reduces the impact of object obstructions and wireless interference.
