What is spectrum?
Spectrum is radio waves that are used to transmit data. Radio waves are measured by wavelength and frequency with most communication networks operating between 300 MHz and 6 GHz frequency.
Why is licensed spectrum needed for private networks?
Licensed spectrum is used for private networks because there is a licensing fee which gives the user the exclusive right to transmit data on their assigned frequency without interference.
What are the benefits of licensed versus unlicensed spectrum?
For private cellular networks, regulators have made mid-band spectrum in the 3.4-4.2 ghz range available. This makes it the optimal frequency to operate large networks as it gives excellent square miles/kilometers of coverage and propagation without significant impacts from commonplace occlusions.
