T-Mobile plans to launch standalone 5G in 2020. Standalone (SA) technology differs from the 5G NR NSA (non-stand-alone) technology that has been launched to date, which is dependent on, and integrated with, a 4G LTE network. Toward its goal, T-Mobile successfully tested 5G NR SA technology in its labs, a first in North America. The test was the first in the world with a multi-vendor network, including equipment from Ericsson, Nokia, and Cisco. The 5G mobile device tested used a MediaTek chipset. The 5G network that Dish plans to build will also use 5G NR SA technology.
