The PEF 3452 H V1.3 interface is a unidirectional RF-interface for point-to-point and point-to-multipoint communication. It is highly suitable for telecom services provided in both frequencies and bands. The PEF 3452 H V1.3 is standardized in ETSI EN 30 489-2, covers multipoint applications in the CP-FSK and FLEX formats and is interoperable with both domestic and international systems.

The PEF 3452 H V1.3 application fields include high speed satellite communication, both terrestrial and maritime mobile services, digital radio streaming, data broadcasting, and remote and terrestrial control. It is an ideal solution for remote video surveillance, low-power digital radio streaming, and mobile WAN communication, utilizing high stability of signal parameters and low warming of the RF chain.

The PEF 3452 H V1.3 supports full-duplex transmission of data and voice communication over RF links. It features low transmission delay and high transmission speed, making it suitable for the transmission of multimedia services. It is also easy to integrate into existing systems, since it uses standard communication protocols and interfaces.

The PEF 3452 H V1.3 working principle is based on the forward-error correction (FEC) scheme, which provides error-free data transfer. It encodes received data packets into symbols. Each symbol is then written into the transmit buffer. The FEC decoder reads the symbols from the transmit buffer and applies FEC error correcting algorithms to detect and correct errors in the data stream.

At the receiving end, the FEC decoder is reverse-activated and reads the symbols from the receive buffer. These symbols are decoded and the FEC algorithms are applied again to correct errors. The decoded data is then sent to the required application.

The PEF 3452 H V1.3 supports both analog and digital transmission, making it suitable for a wide variety of applications. It provides excellent performance in terms of speed, accuracy and stability. Its features make it a reliable, cost-effective solution for telecom services.
