With narrowband line widths at intensities unmatched by globar sources, QCLs have been incorporated into DF instrumentation for chemical sensors, cavity ringdown spectroscopy, and analysis of aqueous samples, as well as microscopy.
This paper presents newly researched and developed network layer protocol for narrowband power line communication (PLC) within the last mile of advanced metering management systems.
Smart meters are interconnected by means of communication links, usually narrowband power line communication to data concentrators at the transformer stations.
This paper analyzes the characteristics of narrowband power line communication (NB-PLC) channels and assesses their performance when used for advanced metering infrastructure (AMI) communications.
In this paper, data transmission through distribution transformers is investigated by means of multiple-input multiple-output (MIMO) narrowband power-line communication (NB-PLC) system, utilizing orthogonal frequency-division multiplexing (OFDM) technology.
In this paper, a multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) system is proposed for narrowband power-line communication (NB-PLC) applications in medium-voltage (MV) networks.
Microsoft's Web sites brought in a trickle of advertising revenue, which did not grow fast enough to offset the disappearance of the narrowband access business.
Although high-voltage transmission lines generally use narrowband PLC for control system operations, the present work implemented both narrow and broadband analyses.
An important decision was to determine which filters the observations would use; WFPC2 is equipped with forty-eight filters, including narrowband filters isolating particular emission lines of astrophysical interest, and broadband filters useful for the study of the colours of stars and galaxies.
"We firmly believe that this business is about having broadband, narrowband, local, long-distance, wireless, and wire-line capabilities, and we think companies that don't have those capabilities are severely limiting their opportunities," the executive said.
