·US51 (T750SE):The"SE" stands for Sector External. Instead of sending a Wi-Fi signal in all directions, it isolates the signal into a narrow120-degree wedgeto blast internet over far distances down a specific path or corridor. It also features dedicated physical RF ports if you need to plug in a custom, external directional antenna.

·US01:This is the baseline, flagship standard configuration. It features anomnidirectional internal antenna arraythat covers a full 360-degree circle around the unit. It also includes onboard GPS tracking hardware, allowing network mapping applications to automatically pinpoint the unit's exact outdoor location on a map.

·US02:This model is identical to the US01, but the factory build omits the physical GPS tracking module to reduce cost. It still maintains the same full 360-degree omnidirectional Wi-Fi coverage.
