5GHz Wi-Fi bridging

The benefits of 5GHz Wi-Fi bridging. The band is less congested then the 2.4ghz frequency and can also offer a much higher throughput it has 23 non overlaping channels unlike the 2.4 Ghz band. Disadvantages are that it is less able to penetrate solid walls and objects so could be less effective than the 2.4Ghz
