The shielding range of the mobile phone jammer is determined according to the size of the Radiation Blocking Cell Phone Case power supply. If the on-site test is based on the strength of the local environmental signal, the shielding range is different, for example, the weak shielding range of the indoor signal is large, and the outdoor use accessories include GSM base stations.
The GSM signal is close to the outdoor shielding range!
- As we all know, 2G, 3G, 4G and 5G: Before buying, you need to know which signals you want the cell phone jammer to block.
- Can selectively block ordinary mobile phone signals (2345G).
- If only 23G or only 34G is shielded, this can be adjusted before leaving the factory, and there are 2.4GWIFI, 5.8GWIFI and other frequency bands.
- Generally, ordinary signals can be quickly shielded.
- Shielded frequency bands: CDMA800, GSM900, SCDMA1800, DCS1800, PHS1900, TD-SCDMA (Mobile 3G), CDMA2000 (Telecom 3G), WCDMA (Unicom 3G).
In recent years, due to the multi-faceted popularity of mobile communication tools such as mobile phones, cheating using mobile communication tools such as mobile phones has become a "secret weapon" for some candidates to improve their test scores. Relying on some illegitimate means, listening to some unscrupulous traders, or organizations and individuals who make profits by providing answers, want to use their mobile phones as answering tools or transmission tools, and obtain ideal test results by fraudulent means, causing serious damage to the fairness of the test and seriousness! For other students who usually study hard and seek truth from facts, it is a great harm! In order to strictly enforce the discipline of the examination room and ensure that every examiner is fair and impartial, by installing Radiation Blocking Cell Phone Case
Mobile phone jammers play a crucial role in maintaining the integrity of examinations and ensuring fair assessment practices. With the widespread availability of mobile communication devices like smartphones, cheating using these tools has become a significant concern in educational settings. Candidates may resort to illegitimate means, such as receiving answers from unscrupulous sources or using mobile phones to transmit information during exams, jeopardizing the fairness and credibility of the assessment process.
To combat cheating and uphold the sanctity of examinations, educational institutions and examination authorities rely on mobile phone jammers. These devices effectively block mobile phone signals within designated areas, preventing candidates from using their phones for illicit purposes during exams. By installing mobile phone jammers in examination rooms, authorities can enforce strict discipline and ensure that every examinee adheres to the rules, promoting fairness and impartiality in assessments.
The shielding range of a mobile phone jammer depends on factors such as the size of the power supply and the strength of local environmental signals. Indoor environments with weaker signals may have larger shielding ranges, while outdoor use near GSM base stations may affect the jammer's effectiveness. It's essential for users to determine the specific signals they want the jammer to block—ranging from 2G to 5G—and select a device with the appropriate frequency bands accordingly.
Mobile phone jammers can selectively block various signals, including CDMA, GSM, 3G, 4G, and 5G frequencies, as well as WiFi signals. These devices are designed to quickly and effectively shield targeted frequency bands, ensuring that unauthorized communication is disrupted within the designated area. By deploying mobile phone jammers strategically, educational institutions can create secure and controlled testing environments, safeguarding the integrity of examinations and upholding academic standards.
installation of mobile phone jammers is a proactive measure to prevent cheating and maintain the fairness and credibility of examinations. These devices offer a reliable solution to combat illicit communication during tests, ensuring that all candidates are evaluated based on their knowledge and abilities alone.
