Assuming we can make efficient use of the subnet mask, and address space is not a problem, this is fine. For our purposes, FA's are NOT tightly coupled to radios. This is an important assumption, becuase there will be multiple overlapping wireless connectivity options, and the applications should be able to decide which meduim to use. The architecture MUST support multiple FA's per cell. Each FA is a wholly independent IP router.
Redundancy is critical too.
