The Advancements in Design and Functionality
As we enter the year 2022, 5G communication technology has become widely popular. With the increasing need for 5G signal blocking, 5G signal blockers have evolved and undergone continuous upgrades from the initial stages of 2G in the late 1990s to 3G, 4G, and now 5G signal blocking. This article explores the development of signal blockers and the challenges faced in terms of frequency bands, antenna quantity, and design.
Evolution of Signal Blockers:
In the early stages of 2G/3G signal blockers, the frequency bands typically covered 4-5 bands, with a corresponding number of transmitting antennas. These signal blockers were housed in metal casings, similar to common WiFi routers, and had a compact size. However, with the widespread adoption of 4G communication technology after 2010, the existing signal blockers with 3-4 frequency band modules were no longer sufficient to block signals from all 2G/3G/4G networks. Consequently, the number of modules in signal blockers gradually increased to 6-8, along with a corresponding increase in the number of antennas.
Challenges with Existing Design:
While most signal blocker manufacturers continued to use metal casings (which also served as heat dissipators), this design approach started to reveal certain drawbacks. Firstly, as the number of modules increased, the heat generated also increased, leading to overheating issues and a higher risk of malfunctions. Secondly, the use of multiple antennas posed challenges in terms of maintenance, as external antennas were prone to damage. Lastly, the aesthetic aspect was compromised, with multiple antennas resembling a hedgehog-like appearance.
The Need for Innovative Design:
By the year 2020, as the era of 5G arrived, the number of frequency bands required for 5G signal blockers had increased to at least 12. Continuing with the traditional flat metal casing design would result in a device that closely resembled a hedgehog. It became evident that a change in the external structure was necessary.
Innovative Modular Design:
As a professional signal blocker manufacturer, we recognized the need for a new approach. Since 2011, we have independently designed and produced dedicated signal blocker molds. Currently, we offer a series of exclusive casings for 4G and 5G signal blockers. While our previous approach emphasized an integrated appearance, our upcoming 5G signal blockers will feature a more creative design: modular assembly.
The evolution of signal blockers from 2G to 5G has witnessed significant advancements in terms of frequency band coverage, antenna quantity, and design. The challenges posed by increased module count, heat dissipation, maintenance, and aesthetics have led to the development of innovative modular designs. As 5G signal blockers are set to enter the market in large quantities, we invite both new and existing customers to explore our range of products. For more information, please contact our company.
