B53 (2400 MHz)

Band 53 operates in the spectrum immediately adjacent to the commonly used 2.4 GHz WiFi band. Adopting a Time Division Duplexing (TDDTDD: A wireless communication technique that uses a single frequency band for both transmitting and receiving operations but separates these operations in time. In a TDD system, upstream (transmission from user equipment to base station) and downstream (transmission from base station to user equipment)…) configuration, this band was introduced by the 3GPP in June 2019. Its establishment was primarily to accommodate the collaboration between NokiaNokia: Nokia Corporation is a Finnish company engaged in the network and Internet protocol (IP) infrastructure, software, and related services market. The Company's businesses include Nokia Networks and Nokia Technologies. The Company's segments include Ultra Broadband Networks, IP Networks and… and GlobalstarGlobalstar: . In the United States, Globalstar holds rights to this particular spectrum. This collaboration aimed at exploring new avenues for LTE deployments and maximising the use of available spectrum, especially in areas where standard 2.4 GHz WiFi bands are congested. The integration of LTE within this adjacent band allows for enhanced network performance and the potential for improved coexistence with traditional WiFi networks.
