Renesas Technology Europe announced has completed development of an enhanced version of its PLC network layer RUN-M. Designed to specifically address requirements for communication over smart metering networks, the Renesas PLC solution comprises a Physical Layer (DCSK based, PLC modulation), a Data Link layer and RUN-M, the Renesas Ubiquitous Network layer for Metering. The major features of RUN-M include intelligent network setup (plug and play), self healing capabilities (response to changing field conditions), intelligent repeating mechanisms (ensuring optimal communication), and unique "NWK topology memory" (to minimise un-necessary network traffic).

Line quality information is provided to the application to allow network statistics to be intelligently used for communication path analysis and management. Cross network communication enables communication between different logical networks allowing comfortable access of handheld units to meters/nodes within range for manual read out/control and simplified load balancing management through communication between concentrators. Impostor detection prevents the network from sharing information with intruders and helps avoid the use of the same NWK & node ID within range. Finally, adjustable gain control allows a more energy efficient communication.
