What is Microwave Technology?

Microwave Technology occupies a specific wavelength range in the electromagnetic spectrum, which is a kind of radio frequency that covers the range of UHF, SHF, and EHF, and is widely used in the field of wireless communication, such as; cellular network, fiber optic transmission, etc.

At the same time, microwave technology is critical to the transmission of analog signals, especially in television broadcasting and radio communications, to maintain signal quality and integrity. This range of wavelengths not only ensures efficient and stable communications, but also supports a wide range of connections from urban to remote areas.

Physical properties of microwaves

Wavelength and Frequency

Microwaves are part of the electromagnetic spectrum and have specific wavelengths and frequencies: the wavelength range is 1mm to 1m, and the frequency is 300MHz to 300GHz. This allows microwaves to provide extremely high speed and efficiency when transmitting data, and it is a key element in the realization of modern wireless communication technologies.

Differences between Microwaves and Millimeter Waves

Millimeter wave is a more advanced precision communication technology than microwave technology. Millimeter wave frequencies are ranged from 30 to 300 GHz and utilize extremely short wavelengths to penetrate the air, enabling fast and efficient information transfer. It is more suitable than microwave technology for high-density data transmission applications, such as 5G wireless networks, virtual reality, and the future of wireless high-speed network services.

Microwave Technology with Different Frequencies

Impact of the Natural Environment on Microwaves

Microwave communications are affected by changes in weather conditions and terrain. When it is raining or in a mountainous area, the signal will be poorer than normal. Through advanced prediction techniques and signal conditioning, communication efficiency can be maintained under different weather conditions. In this paragraph, we will discuss the effects of terrain and climate on microwave communications as well as propose solutions accordingly.

Impact Scenario 1: Shading Effect of Mountains

The occlusion or reflection effect of mountains is a very serious challenge to the propagation of microwave signals. Especially in areas with complex terrain, the signal path can be seriously affected. Therefore, when we are located in mountainous areas, we often experience poor signal and no connection to the Internet.

Solution

The effects of mountainous terrain on microwave communications can be overcome by tuning the positioning of all antennas and setting up relay stations. Precise calculation of antenna deployment position and angle, as well as setting up repeater stations at critical locations, can effectively bypass terrain obstacles and ensure stable signal transmission.

Impact Scenario 2: Wet Weather and Rain Failure

Rain attenuation is a common phenomenon in humid weather conditions, as raindrops can absorb and scatter microwave signals, resulting in a reduction in signal strength, which in turn affects the quality and stability of communications. Since the microwave wavelength of 10 GHz is much larger than the diameter of a raindrop, it will affect the signal transmission and significantly reduce the transmission quality. In addition, rain attenuation can be caused not only by precipitation near the antenna, but also by precipitation at a distance, which requires rethinking and redesigning of satellite communications and terrestrial point-to-point links that rely on precise signal transmission.

Solution

The impact of rain fade can be minimized through techniques and strategies such as station diversity, uplink power control, variable rate coding, larger receiving antennas and hydrophobic coating. These methods help to enhance signal interference immunity, ensure communication continuity and stability, and maintain good communication performance even under extreme weather conditions.
