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.
Electromagnetic waves exist with an enormous range of frequencies. This continuous range of frequencies is known as the electromagnetic spectrum. The entire range of the spectrum is often broken into specific regions.
