Capacity and Cell Sizes
Cell sizes should be calculated based on the number of users, the applications
being used (for example, data/video/voice), and the number of XS-3900 units
available at the location. The capacity of a cell is defined as the minimum data rate
desired for each sector multiplied by the total number of sectors being used.
The following chart shows the maximum recommended cell sizes for each data
rate.
