During March, Indonesia, Madagascar, Bolivia and other countries were hit by rainstorm to varying degrees. The stability and durability of outdoor communication equipment have become a focus of attention.
Mobile phone signals usually weaken in rainy weather because rainwater absorbs and scatters radio waves, especially 4G/5G high-frequency signals.
In addition, humid air and accumulated water can also hinder signal propagation, leading to a decrease in signal strength.
In this context, the combination of waterproof signal booster with outdoor panel antennas and grid antennas with waterproof functions is becoming a key solution to ensure smooth outdoor communication.
The waterproof design of the mobile phone signal booster ensures that signal transmission is not affected by rainy weather, and through use Outdoor Plate Antenna and Grid Antenna with waterproof function
to enhance signal strength and expand coverage.

Callboost launches two high-power signal boosters, CB90C Series Signal Booster and CB95C Series Signal Booster.
1. IP65 waterproof function. Through these materials and designs, the signal amplifier can operate stably in outdoor or humid environments, achieving an IP65 waterproof rating (dustproof, anti low voltage water spray.：
（1）Waterproof shell
Made of high-strength engineering plastics (such as ABS or polycarbonate) or metals (such as aluminum alloy), equipped with sealing rings and waterproof rubber strips to prevent moisture from entering.
（2）Sealing design
Use waterproof joints or rubber sealing rings at the interface to ensure waterproofing at the gaps.
（3）Waterproof coating
Circuit boards and internal components are coated with waterproof coatings (such as nano coatings or epoxy resins) to prevent erosion from humid air or water vapor.
（4）Breathable valve
Install a waterproof breathable valve to balance the internal and external air pressure while preventing moisture from entering.

2. AGC 、MGC function ensure communication stability:
(1) Signal amplification and stability
Compensate for signal attenuation: rainstorm weather may increase the loss of signal transmission media (such as shaft cable, optical fiber, etc.), or reduce the receiving efficiency of the receiving antenna, resulting in a decrease in signal strength. The signal booster with AGC function can monitor signal strength in real time, automatically adjust the gain of the amplifier, keep the output signal stable, ensure that the signal strength is within the range that the device can handle, and avoid receiving interruptions or quality degradation caused by weak signals.
Adaptive signal fluctuation: in rainstorm, the signal may fluctuate rapidly due to scattering, absorption and other factors of raindrops. The AGC function can quickly respond to changes in signal strength, adjust the gain in a timely manner, keep the output signal relatively stable, reduce the impact of signal fluctuations on the receiving equipment, and ensure the continuity and stability of the signal.
(2) anti-interference ability
Suppression of noise interference: rainstorm may introduce various noise interference, such as lightning interference, raindrop noise, etc. The AGC function can adjust the gain to effectively suppress the amplification of noise while amplifying the signal, improve the signal-to-noise ratio of the signal, and enable the receiving device to more accurately decode the useful signal.
Reduce interference impact: The MGC function can manually adjust the gain according to the actual situation. When encountering interference signals at a specific frequency, the gain can be reduced to reduce the impact of the interference signal, while maintaining the strength of the useful signal and improving the signal's anti-interference ability.
(3) Improve equipment adaptability and flexibility
Adapt to different signal intensities: in rainstorm weather, different regions and different receiving equipment may receive different signal intensities. The AGC function enables the amplifier to automatically adapt to different signal strengths without the need for frequent manual adjustments, improving the adaptability and ease of use of the equipment.
Flexible gain adjustment: signal booster with flexible gain adjustment function also means MGC function provides users with the flexibility to manually adjust the gain. Users can flexibly adjust the amplifier gain within a certain range according to their actual needs and signal characteristics, in order to achieve the best signal amplification effect and meet the personalized needs of different users for signal strength.
