WebThe key considerations that affect range are: signal type, antenna, obstructions, and signal strength (wattage). No single factor is a silver-bullet to extend your communication range. But taken in combination, they can mean the difference between getting 1/2 mile range, vs 6 miles or more. Let's discuss each of these. WebOne is that the higher the frequency of a wireless signal, the shorter its range. For example, 2.4 GHz networks cover a substantially larger range than 5 GHz wireless networks. 5 GHz networks do not penetrate solid objects such as walls nearly as well as do 2.4 GHz signals. This can limit an access points reach inside buildings like homes and ...
