After many difficulties along the way, Armstrong launched his own radio station in to demonstrate the effectiveness of FM.
To accommodate this and other stations following on the FCC allocated a band of frequencies between 42 and 50 MHz. Although there was some initial pain because a few hundred thousand radios had been sold, the band was accepted globally and it is the VHF FM band we know today. The nature of FM meant that signal strength variations did not affect the operation nearly as much as if it had been an AM signal.
When using a frequency modulated signal it is very helpful to have a measure of what is effectively the level of the modulation. This is useful in defining parameters like whether the signal is a narrow band or a wide band frequency modulated signal.
It is also very useful in ensuring that all transmitters or receivers in a system are set to accommodate a standardised level of modulation as it affects parameters like the receiver bandwidth, channel spacing and the like.
To define the level of modulation, figures known as the modulation index and deviation ratio are used. One of the key elements of an FM signal is its bandwidth.
With any frequency modulated signal, sidebands extend out either side. These actually extend out to infinity, but the intensity of them falls away. Fortunately it is possible to limit the bandwidth of an FM signal without affecting its quality unduly. Frequency modulation is widely used in many areas of radio technology including broadcasting and areas of two way radio communication.
Facilities Management resources can also assist in tracking various types of authorized traffic within a facility. FM software is specifically designed to aid in the transparency of health and safety benchmarks and outcomes. It can aid in the documentation of best practices for avoiding workplace accidents, or, in the worst-case scenario, the documentation of the facts around a workplace accident.
Various kinds of health and safety features can save time and effort for busy management teams while also helping the company gain a better reputation. Although it is very useful for day-to-day operations management, CAFM can also be very useful for big picture changes and decision support for the leadership when it comes to making momentous decisions. CAFM systems are invaluable to modern facility managers because they offer all of these features.

To keep growing its subscriber base, Netflix is constantly negotiating new licensing deals with TV shows, networks and film producers, or investing in its own content production. Licensing content involves obtaining rights from the owners of a TV show or movie to stream the content through a service such as Netflix. These gadgets record data about the channel or programme watched by the family members or selected people.
