An outdoor repeater is a device that receives a wireless signal from a router or access point and then retransmits it at a higher power level. This can be used to extend the range of the wireless network to areas that are not well-served by the router's signal.

A mobile signal booster, also known as a cell phone signal booster or a cellular repeater, is a device that enhances cell phone signal strength in a particular area. It works by receiving weak cellular signals from a cell tower, amplifying them, and then rebroadcasting them to mobile devices in the area. Thus a suitable antenna is very import for signal booster working performance.
