n25 (1900 MHz)

The n25 band, commonly known as the 1900+ band, operates around a central frequency of 1900 MHz. The "1900+" designation represents the band's position in the PCS (Personal Communications Service) spectrum, with its frequency block assignments being higher, or "up", from the original 1900 MHz allocation. As an FDD band, it is used for 5G NR communication. Historically, the 1900+ band was used for 2G GSM and 3G UMTS services and was later leveraged for 4G LTE, primarily in North America. This band might see limited usage in other regions due to spectrum allocation and regulatory considerations.
