What are some of the characteristics of the AP cluster?

A six point PMP 100 AP (FSK) cluster can simultaneously serve a maximum number of 1200 SM units. All AP clusters must be synchronized and set to identical downlink percentage and range. AP clusters must be synchronized via GPS to provide for proper operations in all support configurations. Clusters are available in the 900MHz, 2.4 GHz, 5.2 GHz, 5.4 GHz, and 5.7 GHz frequencies.
