How to choose a suitable full-band signal blocker

by LIU YIFA 17 Jun 2024

There are many types of signal blocking devices on the market today. This type of device is called a full-band signal blocker. People also call it a cell phone blocker, signal blocker, signal jammer, wifi signal blocker, etc. The working mode of the full-band signal blocker is determined by the power of the sound wave emitted. The emitted signal can form a shielding space for all signals in a specific space in a spherical or fan-shaped manner, which makes mobile phones and other communication devices lose their connection with the base station. After the full-band signal blocker is turned on, the signal will be directly blocked after the 3-second startup time has passed, so that the effect of mandatory prohibition can be achieved.

Full-band signal blockers can be used in various examination rooms, conference halls, gas stations, cells and other places, and the full-band blocker in the examination room is the most common one for us. Candidates who have applied for the exam are connected to the full-band signal blocker, which is also to ensure that the fan-shaped test is fair and reasonable.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
