Let’s discuss the similarities and differences in bandwidth, data rate and throughput. In the wireless industry, these words are used interchangeably and can sometimes be a little bit confusing. All three of these terms help define the speed at which a device or network sends and receives data. Let’s define them and then discuss the differences and similarities as we use them in the world of wireless.
A Wireless Spectrum Analyzer can be described as a frequency-selective, peak-responding voltmeter adjusted to display the rms value of a sine wave. It can be used to display power directly but cannot be used as a power meter. This can only be done as long as we know some value of the sine wave and the resistance across which we measure this value, only then one can calibrate the Wireless Spectrum Analyzer to indicate power. Here is a study of the fundamentals of Wireless Spectrum Analyzer:
A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. They examine the spectral composition of electrical, power, acoustic or optical waveform. The Spectrum Analyzer works by splitting a signal into amplitude and frequency component. From sub audio, audio and radio frequency analyzer, today, there are different varieties of Spectrum Analyzers to choose from.
Bandwidth refers to how fast a device can send data over a single cable usually measured in bits per second. A great example of bandwidth is to imagine a Four-lane highway with traffic going in the same direction. The total width of the highway determines how many cars if side-by-side can fit on the road.
Over the years, video surveillance has become almost a necessity for any home and business security plan. Along with Video Monitoring & Surveillance Devices, high tech locks, access control systems, security alarm, etc. are being widely used by a number of house owners all around the world. For homes, the installation of video surveillance ensures that there is no trespassing, forced entry or theft. Likewise, businesses are vulnerable to various crimes and security issues; thus, installing a video surveillance system helps in monitoring the workplace and the entire system.
