EWA developed “Cumulative Overlap Percentage” to determine the general suitability of one shared frequency over another. Using your requested system parameters, Cevo will first identify channels that are available for certification in compliance with the FCC’s operational and technical rules, and will then rank the available channels by determining the gross cumulative percentage overlap of all co-channel interfering contours that penetrate the proposed system’s predicted service area. For example, one co-channel interfering contour may overlap your customer’s service area by only 5%, and a second co-channel system may overlap your customer’s predicted service area by 50%. The cumulative overlap would be reported as 55% for that particular channel. Other available channels that report significantly higher levels of cumulative overlap may not be the best choices. In all cases, we recommend that you review as well the list of co-channel licensees that are also automatically available through Cevo Pro, to help you determine which channels may be optimum. Co-channel user lists may be accessed on the same page where cumulative overlap results are reported, and the same page where you may make your frequency selections. User details include technologies is use, user classes and other relevant information. With your local knowledge, coupled with cumulative overlap and co-channel user information at your fingertips, the process of selecting shared channels is significantly improved.
I plan to use Cevo Pro because it will permit me to apply my knowledge and experience of local market conditions. What tools does Cevo Pro provide that will enable me to select the “best” shared channels for my customers?
