My old home cordless phone broke down with the display showing nothing. I had to decide buying a new 1.8 GHz or 2.4 GHz cordless phone. In fact, the choice is not difficult. 2.4 GHz band is a junk band with lot of devices sharing the frequency channels like WiFi, Bluetooth, alarm, wireless camera and many more. When I open my netbook and scan the available WiFi in the neighbourhood, I find 17 SSIDs. Thus, the chance of interference in the 2.4 GHz is many times higher than the 1.8 GHz band.
I believe I have made a smart choice in not purchasing a 2.4 GHz cordless phone.
