Turning on all cell phone jammers and running them will increase electricity consumption

Introduction to main components of cell phone jammer system

1. Detector of cell phone jammer system:

1.1 Introduction

The detector of cell phone jammer system can accurately detects such cell phone signals including CDMA、GSM、DCS、PHS (3G included) and so on. It will output a group of high level driving signals and a group of communication signals when detecting the cell phone signals.

The high level signal will be outputted into the NC box to control extension of equipments. The communication signal will be sent to the computer mainframe to record relevant information for the future inquiry.

1.2 Main technical indices of detector cell phone jammer system

1.2.1 Detecting and receiving frequency width

a. Lock receiving frequency RX frequency (CDMA) 824MHz~849MHz（133）

b.Lock receiving frequency RX frequency (GSM) 890MHz~915MHz           (134/135/136/137/138/139/158/159）

c. Lock receiving frequency RX frequency (DCS) 1710MHz~1785MHz（130/131/132 and dual-frequency cell phone）

d. Lock receiving frequency RX frequency (PHS) 1920MHz~1980MHz (PHS/3G video phone)

Demerit of only installing cell phone jammer in current school in China

·Inconvenient for switching on or off uniformly and centrally

When there are two many sets of cell phone jammers, especially when the shielding is applied to many teaching buildings, it is hard to switch on or off uniformly and centrally. Even if the power line is arranged centrally, the specific personnel should be assigned to turn it on or off periodically.

·The information concerning about working state and fault status of the cell phone jammer can not be got correctively and timely.

After energizing all cell phone jammers through the centralized power switch, the managing personnel cannot be timely informed whether the cell phone jammer works normally or not.

·Not energy-saving and environment-friendly and bad for equipment maintenance

Turning on all cell phone jammers and running them will increase electricity consumption, which is bad for energy saving and environment.
