With the advent of the 5G era, the use of mobile phones has reached new heights. In order to effectively block all signals, including 2G, 3G, 4G, 5G, as well as WiFi 2.4G and ?, mobile signal blockers have undergone significant changes. Looking back 6-10 years ago, when mobile phones were still operating on 2G and 3G networks, only 4-6 modules were required to block these signals. At that time, the majority of mobile signal blockers utilized external antennas. However, this external antenna configuration had its drawbacks, such as antenna misalignment or detachment during repeated assembly.
The Challenges of External Antennas:
The external antenna configuration, although popular at the time, began to reveal its limitations. The repeated assembly of mobile signal blocker antennas often resulted in loose or twisted connections. This not only compromised the effectiveness of the signal blocker but also posed a risk of damage to the SMA connectors. In situations where the signal blocker was not securely fixed, operators would inadvertently pull on the antenna, leading to the breakage of SMA connectors. In more extreme cases, during fixed installations, antennas were forcibly removed or even discarded, causing damage to the device’s power amplifier. Furthermore, the increasing prevalence of 4G and 5G networks has necessitated the use of 10-12 antennas in modern signal blockers. This multitude of external antennas not only compromises the aesthetics of the device but also resembles a hedgehog.
The Transition to Integrated Antennas:
To address the limitations of external antennas, a shift towards integrated antennas has emerged. Integrated antennas are designed to be built-in, eliminating the need for external attachments. This new configuration offers several advantages over the previous model. Firstly, the risk of misalignment or detachment during assembly is significantly reduced, ensuring a more reliable and stable connection. Secondly, the integrated antennas enhance the overall appearance of the signal blocker, providing a sleek and streamlined design. This is particularly important in today’s market, where aesthetics play a crucial role in consumer preferences.

As mobile technology continues to advance, the evolution of mobile signal blockers has become imperative. The transition from external to integrated antennas represents a significant improvement in terms of functionality and aesthetics. By eliminating the drawbacks associated with external antennas, integrated antennas offer a more reliable and visually appealing solution. As we embrace the 5G era, it is crucial for manufacturers to adapt to these changes and provide consumers with signal blockers that effectively block all signals while maintaining a modern and attractive design.
