Lowband 5G is a type of 5G that uses low frequencies, just as 4G does. Lowband 5G has long range (meaning you can be far away from a tower or inside a building and still get signal) but slower speeds than other types of 5G. Lowband 5G is only a little bit faster than the LTE (Long Term Evolution) version of 4G. Lowband 5G usually has speeds of around 100 Mbit/s.
