5G focuses on OTA

In 5G, highly integrated massive MIMO antenna systems that support beamforming are superseding classic sector antennas. These systems must be characterized over the air – a challenge for T&M manufacturers and system developers alike. Achieving the needed high channel capacity in a 5G network requires rolling out massive MIMO base stations along with networks and mobile stations implementing both microwave and millimeter wave technologies. In 5G, the microwave range is designated as frequency range 1 (FR1, 410 MHz to 7.125 GHz) and the millimeter wave range as frequency range 2 (FR2, 24.25 GHz to 52.6 GHz).
