Spectrum Dashboard should show band information from service rules not just allocations
At present the Spectrum Dashboard appears based solely on the allocation table. In some cases there are no service rules for parts of bands for a given service so the data indicated is misleading. For example, a search on 854-894 MHz indicates that Part 90 and cellular overlap. Business/Industrial Land Transportation Service is shown as being in 854 - 894 MHz for example. In reality, the services rules in Part 22 and Part 90 make it clear that they don't. Part 90 ends at 869 MHz.
This is a general problem since the allocations are often broader than the service rules and makes the current Spectrum Dashboard somewhat misleading.
It will take time to dig the actual band edges from the service rules, but not much more effort than has already been invested. It is worth the effort.
