CLEAR is the actual provider, but the other 3 are simply "virtual operators" or really "Network Service Providers" while Clear provides the towers. So it's no wonder that they all look exactly the same except for the ID: because they are all coming from the same exact radios at the base station. If there was more than one WiMAX provider in your area (not just CLEAR and 3 others reselling CLEAR under their own name) then you'd see different results.
