Difference between Handheld UE vs VSAT

5g ntn 5g ntn satellite communication

This page distinguishes between two main types of user terminals used in 5G NTN.

Handheld UE: A device comparable to a standard smartphone or a small IoT device. It is assumed to have a maximum transmit power of 23 dBm and a low gain omnidirectional antenna.

VSAT (Very Small Aperture Terminal): A larger, primarily stationary or vehicle mounted terminal. It is assumed to have a much higher transmit power (e.g., 33 dBm) and a high gain directional antenna (e.g., a phased array or parabolic dish).

Key differences

Summary: VSATs have significantly higher power and antenna gain, enabling better performance, while handheld UEs are designed for mobility with lower RF capabilities.
