B25 (1900 MHz)

LTE Band 25, referred to as PCS 1900 G, is an extension of the primary PCS spectrum. Positioned in the 1900 MHz range, it differentiates itself by incorporating an additional guard band. This inclusion was a strategic decision aimed at reducing interference risks with neighbouring frequencies.

While its primary deployment is observed in the United States, the technical nuances of Band 25 have influenced spectrum management discussions in other regions. Its evolution serves as an example of the industry's approach to maximising spectral efficiency and managing interference challenges.
