Cellular network for uplink AMI. State-of-art CDMA and path-loss models

This document contains sufficient information about the CDMA propagation model applied in our AMI (Advanced Metering Infrastructure), In this proposal the aim is to provide more supply, reading, cutting and re connections, prepaid services that focus on the specific characteristics of the inhabitants of rural areas and services that let you know the power consumption in real time in relation to the cost that represents it. To what smart meters to provide that information to our central information and be propagated in cell phone for the subscriber has its consumption without expecting a return is required. The use of CDMA technology in electrical measurement systems help reduce the costs of non-technical losses and that is where we can make the most of this new system as it would improve the quality of the electrical system getting real data readings and allowing improve communication between supplier and consumer.
