Understanding the Effective Interference Range and Proper Installation of Signal Blockers
Signal Blockers are commonly used in examinations to prevent cheating through unauthorized communication devices. However, there are certain misconceptions that need to be addressed to ensure their effective use. This article aims to shed light on two important aspects of using Signal Blockers: the effective interference range in different environments and the proper installation guidelines.

Effective Interference Range in Different Environments
The effective interference range of Signal Blockers varies depending on the signal strength in the area. It is crucial to select the appropriate jammer based on the specific circumstances. The strength of the signals present at the location directly affects the interference range. Therefore, it is essential to assess the actual conditions before choosing the appropriate jammer.
Proper Connection of Antennas
Each antenna of a Signal Blocker corresponds to a specific position. Before activating the jammer, it is imperative to ensure that each antenna is securely connected. Under no circumstances should the device be used without antennas. In case of accidental disassembly of the jammer’s casing, it is advised not to arbitrarily dismantle or reassemble the antennas.
Temperature Increase during Prolonged Operation
After prolonged operation, the surface temperature of the jammer may rise above 40 degrees Celsius. This temperature increase is a normal phenomenon caused by the conversion of electrical energy into heat by internal components. Therefore, there is no need to be concerned about this temperature rise.
Proper Installation Height and Location
The Signal Blocker should be installed at a height of 1.8m-2.5m, ensuring there are no obstacles between the jammer and the target shielding area. This installation height allows for optimal signal interference without any hindrances.
To effectively utilize Signal Blockers in examination settings, it is crucial to understand the effective interference range in different environments and follow proper installation guidelines. By considering these factors, educational institutions can ensure a fair and secure examination environment, free from unauthorized communication devices.
