What should you do if a customer wants to provide certain areas within wireless coverage at a specific data rate?
A.
Perform a single survey
B.
Map out higher data rate cells only
C.
Find out where the coverage pool is for one data rate, and calculate the rest based on that information
D.
Find out how much throughput the user will require

There will be “pools” of coverage at each data rate. If the customer wants to provide certain areas with coverage at a specific data rate, you may have to perform multiple site surveys. You may have to survey at each data rate and find out where the coverage pool is for each.
The Cisco Aironet Site Survey Utility surveys are at a given rate and do not rate shift. You will need to map out the higher data rate cells so they can be shifted to the proper areas. You will need to map out the lower data rate coverage cells with an eye on the overlap of these cells and on frequency selection.
Remember, an overlap of approximately 15 percent is required for smooth, reliable handoffs between access points (APs). This mapping can be time consuming but may well be necessary, depending on the customer’s needs. Before you start surveying, you should find out how much throughput the users will require. This will be one of the factors that will help you determine where you need to place the APs.
