Samsung Network Vision equipment are highly distinct and fairly easy to spot compared to the equipment that other vendors are deploying. Sprint is Samsung's first extremely massive American contract (baring Clearwire) so there should be no issues in confusing these equipment for another carrier which happens often with Ericsson NV equipment.
Below are images of Samsung equipment which includes antennas, remote radio units, base stations, and their mounting configurations.
