A standalone (SA) 5G network uses a 5G core and is built specifically for 5G service. Some other networks were built for 4G and had 5G capabilities built over them as a way to get 5G service to the market faster. 5G SA service offers ultra low-latency, larger capacity, faster speeds, and more reliable and secure service.
T-Mobile today announced that it achieved 5G download data speeds on its SA network faster than 4.3Gbps using eight aggregated channels of high-band mmWave spectrum without requiring low or mid-band signals to anchor the connection. Four channels of aggregated mmWave spectrum were used to deliver upload data speeds faster than 420Mbps.
