AmberWaves is a WISP in northwest Iowa. One of their clients has 3 offices linked by an 802.11 network with 35 employees. The greatest distance between the 3 offices is 19 miles.
This wireless network enables the firm to be its own internal data and voice service provider. The use of Vo802.11 frees the firm from local and long-distance telephone bills. The end users report that the QoS on the network is better than the frame relay circuit they previously used (see Figure 6-11).
