Fixed wireless commonly costs more than AirCards, but fixed wireless includes several advantages over AirCards. AirCards are designed to work with a single provider. If that provider does not have the strongest signal of the four providers included with 3G, then the fixed wireless circuit will be much stronger than an AirCard. Also, the antenna included with fixed wireless is often about 10 times larger, and more powerful than the antenna of an AirCard. For this reason, the circuit strength of fixed wireless is often many times stronger than a circuit supported by an AirCard.
