A WIFI booster takes an existing wireless signal and rebroadcasts its signal in another area. One may ask the point of a piece of equipment that does a trivial task of basically re-sending out a wireless signal, but such equipment actually has high utility in many workplaces and residential areas. Wireless internet based off a WIFI connection allows people in its range to enjoy an internet connection on their laptop or smartphone without using any physical wires. However, the WIFI signals also are subject to the laws of physics and engineering; WIFI signals only have a certain range before the strength of the signal rapidly becomes weak. Plus, there may be areas where the frequencies are altered or where the signal is weak due to interference from building material. In these situations, WIFI boosters are invaluable tools.
By using WIFI boosters, a wireless signal’s range can be extended significantly. This allows for more access to a wireless network in a residential or commercial area. Using boosters can often be more practical than investing in a stronger but costlier wireless access point that can broadcast its signal through a farther range. In addition, WIFI boosters allow for wireless access in areas where interference may be an issue with the original broadcasting signal, or in less open areas such as hallways and corridors. WIFI boosters in this situation would be more efficient and less costlier. However, there are downsides of using WIFI boosters compared to a stronger WIFI signal. The main downside is latency; WIFI boosters can slow internet speeds and responsiveness due to the inherent inefficiency of rebroadcasting a signal. Also, internet speeds slow down more with additional users via WIFI boosters compared to using a wireless access point with a stronger signal.
