RF antennas are a fundamental part of any wireless communication system, and can dramatically affect the performance of the underlying network. The PU-M4-315 is a type of RF antenna which is widely used in a variety of applications, from cellular networks to IoT networks, to ensure high performance and reliability. In this article, we will discuss the application field and working principle of the PU-M4-315.

Application Field

The PU-M4-315 is a 4G-type antenna which is designed for use in LTE applications. It is widely used in cellular networks, where it is employed to ensure superior performance in terms of signal coverage and data speeds. Furthermore, the PU-M4-315 also supports iFSD (In-Flight Music Streaming Data) protocols, allowing passengers to listen to music during flights, as well as MIMO (Multiple Input Multiple Output) technology, which allows for increased network capacity by multiplexing multiple data streams.

The PU-M4-315 is also suitable for use in IoT networks, where it can be used to transmit data from sensors for a range of different applications. The antenna is highly resilient, with a low power requirement and resistance to interference. It is also capable of transmitting data up to 100 m in free space, allowing for long-distance communication.

Working Principle

The PU-M4-315 operates using the frequency division duplex (FDD) approach, where a pair of frequencies are used to transmit data in both directions. The transmission frequency is 2.6 GHz, and the receiving frequency is 2.5 GHz. The antenna employs a linear polarization and directional beamforming, with a maximum radiation angle of 45 degrees. This allows for a highly directional signal beam which concentrates the transmitted energy onto the desired target.

The PU-M4-315 also employs a number of other technologies to improve performance. These include beam tracking, which increases the range and accuracy of the antenna by continuously adjusting the direction and gain of the signal beam. There is also beamforming using multiple channels, which allows for the antenna to function even in environments with high levels of interference.

The antenna is also capable of utilizing multiple access techniques to communicate with multiple users simultaneously. This is achieved by assigning different frequencies to each user, allowing for a more efficient use of the limited radio frequency spectrum available. Furthermore, the antenna is also able to detect the presence of a user at a distance, without impairing their signal, through the use of receiver beamforming.

Conclusion

The PU-M4-315 is a highly reliable and versatile antenna which is suitable for a wide range of applications, from cellular networks to IoT networks. It utilizes the FDD approach, with a transmission frequency of 2.6 GHz and receiving frequency of 2.5 GHz. The antenna also utilizes a number of other technologies, such as beam tracking and beamforming, to improve performance and ensure reliability. In conclusion, the PU-M4-315 is an excellent choice for high performance RF antennas.
