n20 (800 MHz)

This 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, used for 5G New Radio (NR) networks, operates around a central frequency of 800 MHz. Initially seeing major usage 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… services in Europe, it is now being repurposed for 5G deployments globally. The lower frequency range of the n20 band enables excellent coverage and signal penetration, suitable for both urban and more remote regions. However, the n20 band might overlap with similar bands such as n28 (700 MHz) in some regions, requiring careful coordination for deployment. As it overlaps with n28 it is not used in Australia or New Zealand. Interestingly, n20 has a lower frequency downlink frequency range than its uplink, leading to a negative duplex value.
