Band n53 adds premium midrange spectrum to the premium performance of XCOM RAN. As midband spectrum, it provides a balance of speed and coverage for 5G with download speeds up to 250 Mbps and upload speeds up to 100 Mbps, wider coverage than millimeter-wave frequencies and greater efficiency than lower bands for better throughput. If you run the wireless networks that run the world, the combination of band n53 and XCOM RAN is a marriage made in heaven. Learn more in the Terrestrial Wireless section at www.globalstar.com.
