Electricity metering data exchange - Lower layer PLC profile using Adaptive Multi Carrier Spread-Spectrum (AMC-SS) modulation

This Technical Specification specifies the physical layer, medium access control layer and logical link control layer for communication on an electrical distribution network between a master node and one or more slave nodes using adaptive multi-carrier spread spectrum (AMC SS) technique. The adaptive cellular communication network technology provided in this specification may be used for automated meter reading as well as for other distribution network applications.
