On-site communication sealing systemIs a can effectively shield2G/3G/4GFull-form mobile phone signalCommunication JammerTo send a corresponding interference signal for different modulated signals in order to achieve the best interference effect with a smaller interference power. ForTD-SCDMAAndTDD-LTECan be stable synchronization with the public network base station, zero interference to the upstream.Sealing systemUsing the multi-unit network mechanism,By1 main sealcontrol equipment and two small power communication interference equipment composition. Depending on the environment that is required to be sealed on site,SupportOn-site disposalMultiple machines work steadily at the same time.
Applications
Group event on-site communication shield emergency disposal
Confidential meetings
Prison
School examination room
Communications sealing of large venues
