Product characteristics:
1. Performance
The device adopts the design scheme of its channel micro-power transmission and high gain directional transmitting antenna, with no channel minimum gain of 7 dbm. As we all know, in the field of wireless signal transmission, the US will double the shielding distance per gain of 3 dbm, so the shielding distance of this smartphone signal shielder is at least five times that of the conventional shielder on the market. And its transmitting power is only 2W, the radiation value is lower than other shield!
2. Function
It can shield for a long time and save energy. The design of seven-channel frequency hopping transmitter ensures that it does not affect the upstream frequency and does not interfere with the base station.
