n20 (800 MHz)

This FDD band, used for 5G New Radio (NR) networks, operates around a central frequency of 800 MHz. Initially seeing major usage for 4G LTE 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.
