Wifi amplifier

A WiFi amplifier is a device that can improve the strength of a wireless networking signal. The term WiFi amplifier can refer to a replacement antenna that produces a significant signal gain, through repeaters, and even passive antenna augmentations, are sometimes referred to as amplifiers.
Antenna based amplifiers are typically designed to replace stock antennas on wireless routers. These amplifiers typically require an external power source to boost the signal.
Repeaters are separate devices that can be placed at the edge of a wireless signal to rebroadcast it into a dead zone.




There are a number of different devices that are commonly referred to as WiFi amplifiers, though most of them do not actually amplify anything. These devices are often installed in place of the factory antenna, and contain circuitry that is capable of boosting the transmission signal. Some of these amplifiers can also be installed in-line with a high gain antenna, which can improve both transmission power and the ability to receive weaker signals.
