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 FDDFDD: A communication technology that uses separate frequency bands for transmitting and receiving operations. This technique enables simultaneous bi-directional communication by allocating one frequency band for upstream (transmission from the user equipment to the base station) and another distinct… band, it is used for 5G NR5G NR: 5G was developed with three broad use case families in mind: enhanced mobile broadband (eMBB), massive machine-type communications (mMTC) and ultra-reliable low-latency communications (URLLC). eMBB focuses on across-the-board enhancements to the data rate, latency, user density, capacity and… communication. Historically, the 1900+ band was used for 2G GSM and 3G UMTS3G UMTS: UMTS is an umbrella term for the third generation radio technologies developed by the 3GPP. UMTS specifies a complete network system, for which the radio access component, known as UTRAN, uses WCDMA technology to offer greater spectral efficiency and bandwidth to mobile network… services and was later leveraged for 4G LTE4G LTE: 4G LTE (Long Term Evolution) or the E-UTRAN (Evolved Universal Terrestrial Access Network), introduced in 3GPP Rel. 8, is the radio access component of the Evolved Packet System (EPS) - a purely IP based mobile network standard. As an evolution to 3G UMTS, 4G LTE shares many similarities, such as…, primarily in North America. This band might see limited usage in other regions due to spectrum allocation and regulatory considerations.
