RF Wireless Module Transmission Mode : Microwave Twisted-Pair

Microwave transmission

It is one of the solutions to several kilometers or even dozens of kilometers of difficult wiring location monitoring transmission. By means of RXB22 frequency modulation or amplitude modulation, the image is carried on the high frequency carrier and converted into high frequency electromagnetic wave in the air transmission. Its advantages are: low comprehensive cost, more stable performance, save wiring and cable maintenance costs; Dynamic real-time transmission of broadcast grade images, image transmission clarity is good, and completely real-time; Flexible networking, good expansibility, plug and play; Low maintenance costs. Its disadvantages are: due to the use of microwave transmission, frequency band above 1GHz, commonly used L band (1.0 ~ 2.0GHz), S band (2.0 ~ 3.0GHz), Ku band (10 ~ 12GHz), the transmission environment is open space, if used in big cities, radio waves are more complex, relatively easy to be affected by external electromagnetic interference; Microwave signal for linear transmission, the middle can not have mountains, buildings block; If there are obstacles, it is necessary to add relay to solve them. Ku band is seriously affected by weather, especially in rain and snow weather, there will be more serious rain decline phenomenon. However, there are also digital microwave video transmission products, RXB22 anti-interference ability and scalability are improved a lot.

Twisted pair transmission

It is also a kind of video baseband transmission, which converts the unbalanced mode of 75Ω into balanced mode to transmit. It is a good solution to solve the problem of monitoring image transmission within 1Km, the electromagnetic environment is relatively complex and the occasion is better, and the monitoring image signal processing is transmitted through the balanced and symmetrical way. Its advantages are: simple wiring, low cost, anti - common mold dry worry performance. Its disadvantages are: it can only solve the monitoring image transmission within 1Km, and a twisted-pair cable can only transmit the image all the way, which is not suitable for large and medium-sized monitoring; Twisted pair is weak in texture and has poor anti-aging ability, which is not suitable for field transmission. Twisted pair transmission high frequency component attenuation is large, the image color will suffer a great loss.

Wireless communication has revolutionized the way we transmit data across the globe. One of the most popular forms of wireless communication is RF wireless microwave transmission. This technology has been around for decades and has been used in various applications, including telecommunications, broadcasting, and satellite communication. In this article, we will delve deeper into RF wireless microwave transmission and understand how it works.

RF stands for Radio Frequency, which is a range of frequencies used for wireless communication. RF wireless microwave transmission uses electromagnetic waves to transmit data wirelessly. It operates in the microwave frequency range, which is between 1 GHz to 300 GHz. The wavelength of these electromagnetic waves is between 1 millimeter to 1 meter. RF wireless microwave transmission is widely used due to its high data transfer rate, low latency, and long-range capabilities.

One of the most common applications of RF wireless microwave transmission is in telecommunications. Mobile phones, Wi-Fi routers, and other communication devices use RF wireless microwave transmission to communicate with each other. These devices have an antenna that receives and transmits data in the form of electromagnetic waves. The data is then decoded by the receiving device, which converts it into a usable form.

RF wireless microwave transmission is also used in broadcasting. Television and radio stations use this technology to broadcast their programs to a wide audience. The data is transmitted from a broadcasting station to a receiving antenna located in the viewer's home. The receiving antenna captures the electromagnetic waves and decodes them into the broadcasted program.

Satellite communication is another application of RF wireless microwave transmission. Satellites orbiting the earth use RF wireless microwave transmission to communicate with ground stations. These satellites transmit data to and receive data from the ground station using electromagnetic waves. This technology is used for various applications, including weather forecasting, GPS, and military applications.

RF wireless microwave transmission has several advantages over wired communication. It allows for mobility, which is not possible with wired communication. It also has a higher data transfer rate and lower latency compared to wired communication. Additionally, it is more cost-effective than wired communication, especially in remote areas where laying wires is not feasible.

However, RF wireless microwave transmission has some limitations. The signal strength decreases as the distance between the transmitter and receiver increases. This limits its range and requires additional equipment to extend the range. It is also susceptible to interference from other devices, which can cause signal distortion or loss.

In conclusion, RF wireless module RXB22 is a popular and widely used technology in various applications, including telecommunications, broadcasting, and satellite communication. It uses electromagnetic waves to transmit data wirelessly, providing high data transfer rates, low latency, and long-range capabilities. However, it has limitations such as limited range and susceptibility to interference. Despite these limitations, RF wireless microwave transmission is an essential technology that has revolutionized the way we communicate and transmit data wirelessly.
