The FG3603 is a family of very high frequency (VHF) radios which is designed for use in smart mobile communications systems. This family of radios offers a wide range of features, including multiple antenna connections, advanced modulation schemes, high-power capability, wide bandwidth coverage, and the ability to integrate into cellular and mobile communications systems. This article will provide an overview of the FG3603 application field and working principle.

FG3603 Application Field

The FG3603 family of radio systems is designed for use in cellular and mobile systems. This includes cellular networks, mobile radios, and cordless telephones. The radios can be used in many different contexts, from short-range communications to long-distance connections. They have the ability to function in all land mobile radio bands, including the 800 MHz, 900 MHz, and 1.2 GHz bands. The radios are also capable of extending coverage to low-frequency (LF) and very low frequency (VLF) bands, as well as taking coverage of multiple frequency bands by using multiple antennas.

The FG3603 family of radios is also designed for use in public safety and security systems. These radios can be used in a variety of applications, including fire and police communication systems, search and rescue operations, and military networks. The radios are also capable of providing secure data transmission for medical, aviation, and industrial applications.

The FG3603 family of radios is also capable of providing coverage in high-traffic areas. They can be connected to a network of multiple antennas, which can cover large geographic areas and provide access to mobile radio, cellular, and cordless telephone systems. This is especially useful in areas where land mobile radio coverage is limited or unavailable.

FG3603 Working Principle

The FG3603 family of radios operates using a time divisional multiplex access (TDMA) technique. In this technique, the radio system is divided into a number of timeslots. Each timeslot is allocated an equal amount of time. When a transmission is requested, the timeslot is assigned, and the transmission takes place during that timeslot.

The FG3603 also uses frequency hopping to reduce interference and enhance transmission security. In this technique, the radio transmits at different frequencies in rapid succession. This makes it difficult for an unauthorized party to “listen in” on the transmission and also helps to reduce radio interference from other radio users.

The FG3603 also uses a spread spectrum technique. This technique spreads the information to be transmitted across a wide range of frequencies. This makes it more difficult for an unauthorized party to intercept the transmission. At the same time, it also helps to reduce the likelihood of interference from other radio users. All of these techniques help to ensure that transmissions are secure and reliable.

Conclusion

The FG3603 is a family of VHF radios designed for use in mobile communications systems. These radios provide high-power and wide coverage, as well as the ability to integrate into cellular and mobile communication systems. They also feature multiple antenna connections and advanced modulation schemes for secure and reliable data transmission. The radios employ TDMA, frequency hopping, and spread spectrum techniques to reduce interference and enhance security. The FG3603 radios are ideal for use in public safety and security systems, as well as for extending coverage to LF and VLF bands.
