Enhancing Signal Blocking Efficiency for 1800MHz Frequency Band
Cell Phone Jammers are devices designed to block signals from various mobile communication standards such as 2G, 3G, 4G, and 5G. To effectively shield these signals, a standard 5G Cell Phone Jammer must cover a frequency range from 700MHz to 4960MHz. While seamless coverage is not necessary within this wide bandwidth, it is crucial to target the frequency bands used by mobile phones. Among these bands, the 1800MHz frequency band stands out as it encompasses different standards used by China Mobile, China Unicom, and China Telecom. This article explores the significance of frequency division in Cell Phone Jammers, particularly for the complex and congested 1800MHz frequency band.
The Complexity of the 1800MHz Frequency Band
The 1800MHz frequency band, ranging from 1805MHz to 1920MHz, is the most congested and complex frequency band for Cell Phone Jammers. According to the latest planning standards from the Ministry of Industry and Information Technology, the 1805-1830MHz range belongs to China Mobile’s 2G band, 1830-1860MHz is allocated to China Unicom’s 3G and 4G bands, 1860-1880MHz is assigned to China Telecom’s 3G and 4G bands, and 1885-1920MHz is designated for China Mobile’s 4G or 5G bands. Each communication operator deploys 3G or 4G base station signals based on their specific requirements. Therefore, it is crucial for Cell Phone Jammers to prioritize and strengthen the blocking power for the 1800MHz frequency band while ensuring a reasonable division of shielding modules.
Optimizing Frequency Division for 1800MHz Frequency Band
Currently, mainstream Cell Phone Jammers typically adopt a frequency division scheme that divides the band into two segments: 1805-1880MHz and 1880-1920MHz. However, this is not the most optimal solution. To achieve better signal blocking efficiency, it is recommended to divide the 1800MHz frequency band into three segments: 1805-1830MHz, 1830-1880MHz, and 1880-1920MHz. This division aligns with the frequency range and allocation of different communication operators, ensuring comprehensive coverage and improved signal blocking performance.
Cell Phone Jammers play a crucial role in blocking signals across various mobile communication standards. The 1800MHz frequency band, with its complexity and congestion, requires special attention in terms of signal blocking power and module division. By adopting a three-segment division for the 1800MHz frequency band, Cell Phone Jammers can achieve enhanced signal blocking efficiency. This optimized frequency division approach ensures effective shielding of signals from China Mobile, China Unicom, and China Telecom, ultimately improving the overall performance of Cell Phone Jammers.
