China Unicom and domestic vendor ZTE have completed a successful field test of 5G New Radio (NR) technology, achieving peak download speeds of 2Gbps. The trial used a pre-commercial 5G base station using 100MHz of bandwidth in the 3.5GHz frequency band, massive multiple-input, multiple-output (Massive MIMO), low-density parity check (LDPC) and other key 5G technologies.
