PLC is the acronym for ??PowerLine Communication?? and means data communications via power wiring. PLC was initially used for tele-protection and tele-monitoring of electrical substations by means of high voltage power lines, in order to avoid costs of microwave or fiber optic links. More recently, PLC has been also adopted for automatic smart metering. However, only with the advent of low-cost digital...
The work presented in this paper is related with time synchronization for wireless networks. In particular, it is focused on the proposal and experimental evaluation of a low-cost and high precision timestamping technique based on Ultra Wide Band (UWB) signalling. In recent years, the use of such systems has gained an increasing success thanks to their robustness to interferers and multipath. In this...
The standards for wireless sensor communications usually do not pose severe constrains on time synchronization methods. In fact, when used for communication purposes, an overall time synchronization accuracy on the order of tens of microseconds is well enough. For this reason, timestamping mechanisms (the basic feature exploited by all algorithms) are often not specified. Real world transceivers,...
