The relay mode of the WiFi router is to send on the side of the receiver
In radio transmission, antennas with higher gain will improve a bit, but the effect is far less than you can put the antenna up to higher ground. Effective indoor transmission of WIFI. No more than 50 meters, outdoor (both sides of the transmitter and receiver antenna are outdoors) can reach 200~300 meters. Further distances require the use of external directional antennas.
The router antenna is not the more the better, not greedy big power, signal router in 2-3GHZ, which belongs to the ultra high frequency electromagnetic radiation source is typical, the signal is too strong to increase the speed of Internet access without any promotion (the Internet depends mainly on broadband lines export bandwidth, rather than the router, but the impact of health bandwidth).
There is a little difference between bridging mode and relay, that is, in bridging mode, the second routers will use a completely different channel and their own SSID, for users, as the two AP in the work.
WIFI is a digital signal, in the relay mode to receive the AP signal on the home, and then forward, the channel and SSID will not change, for the receiver, the relay is transparent. There is no difference between the direct charge and the AP signal.
