So the higher the dBi rating, the more powerful the antenna is and whether it will cover the area you need. If you have an antenna that is overloaded, it means there is too much RF energy at the point where signals are being received. However, no matter how much power is radiated, if a receiver cannot capture and demodulate the radio waves properly, then there will be no communications. When you are in line-of-sight (LOS) environments this peak gain is probably all that matters, as long as the antenna is in fact correctly pointed at the other antenna. The other half of the room would be TWICE as bright, because you can see the real candle PLUS its reflection. Saying any 2.2 dBi antenna will yield the same distance ignores the antenna's directivity. The amount of intensification in a preferred direction is quantified as gain. I'm not an expert on antennas, but I've heard about directive antennas.
