Although the system of the individual purpose exists in a home, a network for home use does not exist. There are three important problems to home network realization. It is cost's being cheap, and there being no necessity for construction, and being able to communicate anywhere in a network, if it is domestic again. In order to realize this, the network system which works simultaneously two com...

Automatic Meter Reading (AMR) is the remote collection of consumption data from customer’s utility meters over telecommunications, radio, power line and other links. AMR provides water, electric and gas utility−service companies the opportunities to streamline metering, billing and collection activities, increase operational efficiency and improve customer service. Utility company uses technolo...

This paper presents the first results of a propagation model applied to PLC in aircraft to get the narrow band and wide band channel characteristics. One of the possible applications deals with data communication for the cabin lighting system. Index Terms PLC, Aircraft, Propagation Model, Path loss, Delay Spread.

Presented in the paper is the PLC symbol naming rules in order to simulate the virtual factory which is operated by the PLC control logic. In the PLC simulation, the corresponding model, normally called as the plant model, to the PLC receives the PLC output signal, operates virtual devices, and sends the changed PLC input signal which is updated by the virtual device movements. Therefore the pl...
