With this increased gain, the Fusion4Home 4G wireless signal booster further expands indoor coverage for those who work, live or vacation at the edge of the cellular network. The cellular repeater itself offers up to +72 dB gain, which means using different, more install-heavy antennas, you can increase your coverage without having to buy a new booster.

Simply put, there is no better value for the money on the market. With the Fusion4Home setup, customers can expect 2,000 -5,000 sq ft of coverage (depending on configuration) from this kit. This cellular extender features swappable antennas to increase or decrease coverage range.

I gather from various adaptors referred to, that you have two specialist plugs and you plug one into the router (or the router into it) in some way and other ino a socket in the room where you need the wifi, and they transmit some sort of enhanced wifi signal over the electrical circuit? Some of the replies start from the assumption I know what is required and just need advice on the brand - not so! I know nothing about how to go about getting an enhanced wifi signal.
