B47 (5800 MHz)

Band 47 sits in the 'unlicensed' 5.8 GHz spectrum, employing 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)…). This band functions within the Licence Assisted Access (LAA) framework, enabling mobile network operators to utilise unlicensed spectrum in conjunction with their primary licensed spectrum, thus augmenting network capacity.

Band 47 is tailored for vehicle communications, termed "V2X" (Vehicle-to-Everything). This designates its role in facilitating communication between vehicles and other entities, be it infrastructure, networks, or even pedestrians. Operating in the 5 GHz range, Band 47 ensures reliable and efficient connectivity for vehicular communications, promoting safer and more informed transportation ecosystems.
