How to upgrade the existing full-screen mobile phone signal blocker in the examination room to interfere with 5G?
In various examinations, such as the middle school entrance examination, the college entrance examination, the Chinese language examination, the professional certification examination, etc., it is not uncommon for candidates to encounter a sudden loss of signal on their mobile phones in the examination room. This is because the full-screen mobile phone signal blocker is used to prevent cheating. However, with the widespread popularization of 5G technology, the old full-screen mobile phone signal blocker can only interfere with 4G signals, so how to upgrade to interfere with 5G?
At present, most of the full-screen mobile Cell Phone Jammers used in the examination room adopt a modular design. Different frequency bands are covered by different modules, and the modules can be replaced efficiently for quick repair or increase of frequency bands. Upgrading to interfere with 5G is a problem for many manufacturers because the original design lacks interference modules suitable for different frequency bands. If upgraded to 5G, it is necessary to add an independent module that can interfere with 5G signals to the existing signal jammer, or to launch a full-screen mobile phone signal blocker specifically for 5G jammer.
JAMMERSIGNAL Information Technology Co., Ltd., a manufacturer of full-screen mobile phone signal blockers for examination rooms, took these factors into consideration during the design, and the design allows the addition of different frequency band modules later to meet the needs of functional expansion. By accumulating heat sinks and leaving enough space for heat pipe heat sinks, the original 12-channel air outlet can be expanded to 24-channel air outlets, ensuring that there is no need to worry about insufficient heat dissipation space when more frequency bands are added in the future. By expanding to 24 interference frequency modules, a large number of signal frequencies can be effectively interfered, and the signal shielding level can be improved by optimizing signal frequencies in various scenarios.
