That being said, LTE is not fully baked by any means and requires some technology advancement to be fully realized. LTE also comes in two different flavors: Frequency-Division Duplexing (FDD) used in the west, and Time-Division Duplexing (TDD). If youâve used it on a carrier with sufficient bandwidth, LTE is fast.
An electromagnetic spectrum is defined as the entire range of electromagnetic waves from low to high frequency. An example of an electromagnetic spectrum is the low frequency radio to the high frequency gamma ray waves. the complete range of frequencies of electromagnetic waves from the lowest to the highest, including, in order, radio, infrared, visible light, ultraviolet, X-ray, and gamma ray waves.
The EM spectrum is the range of all possible frequencies of electromagnetic waves. At one end of the spectrum are the waves with the lowest frequencies. At the other end are the highest frequency waves. The spectrum is broken up into regions that define each of the different wave types.
