The basic idea is simple: the device receives an existing wireless signal and retransmits it to help extend coverage into areas that may otherwise have a weak connection. This makes the product particularly interesting for bedrooms, upstairs rooms, home offices, garages, apartments, and other WiFi dead zones.
Swift Power Hub WiFi-Repeater 2.0 is marketed as a compact wireless range-extending device designed to help improve WiFi coverage in areas where the signal from an existing router is weak. Instead of replacing the main router or installing new Ethernet cables, the repeater is designed to work alongside the current WiFi network.
