The method of sluice control applied to reservoir is executed manually in field at present. To fix this problem, sluice remote monitoring system based on GPRS and PLC is provided. Some advanced technologies used in system are discussed. The system structure and principle are introduced. The system realizes wireless network connections between local control unit and center control unit based on ...

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...

Power-line communications (PLC) are employed in home networking as an easy way to provide highthroughput connectivity. IEEE 1901 [3] is the dominant MAC protocol for power-line networks, and its most popular implementation is HomePlug AV. This technical report introduces guidelines for measurements in HomePlug AV testbeds. We describe two tools that manage and configure PLC devices. These tools...

Power line communications (PLC), thanks to the widespread availability of power line infrastructure, is considered as a low-cost alternative for data transmission. Power lines, however, remain hostile environments for communication signal propagation. In this paper, we propose a new transceiver scheme for orthogonal frequency division multiplexing (OFDM)-based broadband power line communication...

A broadband power amplifier designed and implemented in Doherty configuration is illustrated in this paper. Both input and output networks adopt the broadband matching topology. Additionally a compensation network, consisting of a series transmission line shunted with a capacitance, is set behind the peak amplifier to avoid in-band power leakage in the low-power section while at the cost of pea...

“Faster, higher, stronger”– the Olympic motto is being pursued and practised in the design of broadband wireless communication systems. Motivated by the huge demands for fast and reliable communications over wireless channels, broadband communication systems are required to provide faster (lowcomplexity) data processing, higher data throughput and stronger (lower error rate) performance. In pra...
