product overview

LRWTD-BG20The handheld network road test terminal is designed forLoRaThe auxiliary testing equipment developed for on-site testing is divided into standard power（20dBm）Version and high power（30dBm）Version. This road test terminal can perform point-to-point communication testing, testing the surrounding signal coverage of the actual deployed gateway, and testing the background noise within the communication frequency band in the environment. When using road test terminals for gateway installation location selection, gateway actual signal coverage testing, and environmental noise testing, it can effectively reduce redundant workload and greatly improve our work efficiency.
