Information Service Needs
Multiple Networks of different Network_Types may be available in a particular geographical area:
802.11, , Cellular
For each Network_Type (such as ) there may be several operators, providing several instances of a particular Network_Type
Operator_A, B, etc. may all have networks
The properties of these network instances may be different
Network Standards they support (.11a/b/e/g/i/n/p/r/s/u/v…)
Cost, Security, Roaming Agreements etc. for these networks may be different
For each of the above Network Instances, there are different PoAs (APs for )
The properties of these APs may differ: Location, Subnet Information, Capabilities, etc.
