Quick Information

  • Brand Name: Friendcom
  • Model Number : FC-621


We have been devoted in research and design of RF mesh network CFDA for AMR/AMI applications since 2001. CFDA (Cellular Fixed-wireless Digital Access) RF Mesh Network has been successfully used in AMR system of power meters.  Over 3 million CFDA RF modules have been running in the field worldwide especially in China and Asia. It’s a good and practical solution for AMR system with proven experience.

Key features:

§                                            Wireless self-organized mesh network, robust and reliable.

§                                            Strong performance of each node with good penetrating capability .

§                                            Self-adapting frequency hopping, to enhance the anti-interference performance of the system.

§                                            Intellectualized installation----plug and play, no need to configure on the site or configure before installation.

§                                            High data transmission speed: air speed 19200bps.

§                                            Support DL/T 698 and DL/T 645 protocols etc.

§                                            Cellular topological network structure, support network infrastructure of large area with multi base stations, able to connect with large master station system easily.

§                                            Comprehensive network management platform, can easily realize the multi- network management to ensure the optimized status of network.

The essential two parts of CFDA are DAU (Data Access Unit) and CAC(Cellular Access Center). They work in ISM frequency band (UHF/VHF) with good penetrability and diffraction capability and the data speed can reach 20kbps. Its RF part is designed on narrow-band technology with high sensitivity and adopts standard two-stage IF and FSK modulation with features of good anti-jamming capacity and long transmission distance. It also suits other complicated industrial applications.

Besides the good RF performance above, CFDA is remarkable for its mesh routes technology. DAU can relay and forward signal from other DAUs. It adopts seven-layers eight-hops Mesh network structure, This makes wider coverage range possible. A two-way configurable self-organized routes allocation is adopted, this makes the below features available for the mesh network:

. DAU alarm for convenient self-maintenance

. DAU real-time login the network for easy dynamic extension of the nodes

. DAU real-time routes refresh for reliable data transmission

. DAU supports the handheld device to dynamic access for convenient and easy system maintenance.
