VIVILED launched new generation RF module for cross

Transmit distance for from computer indoor: 20 meters with 5 solid walls between


Most of the crosses use wireless as the transmit mothod, can use WIFI, RF or bluetooth, and cross operators normally sit before computer inside the buiding, then they usually has 1 or more than 1 walls betweeen the computer and the cross, in this condition, the operators may have to walk outside and carring a computer to setup the cross or send program, because most of the wifi, bluetooth and normal RF module can’t send signal when the distance is more than 10 meters with solid walls between, while our new RF modules use new LoRa technology can make this happen, led pharmacy cross operators can send program from 20 meters away, 2 or 3 walls can’t block the signal.
