Sub-GHz is a wireless communication technology with a frequency below 1GHz, which has significant advantages in low power, long distance communication and wall penetration. Bonwn had a practical test of Sub-GHz, the experimental results is that the longest distance away from the test point is 526 meters, as shown on the right. The communication distance of Bonwin wireless lock is more than 500 meters in the outdoor environment, the communication distance is 30 meters in indoor environment.With SUB-GHZ technology, and this technology is able to penetrate 3~4 walls to control locks.
