Dish Wireless this week announced the successful completion of simultaneous 5G 2x uplink and 4x downlink carrier aggregation (CA) for Frequency Division Duplex (FDD) spectrum with partners Samsung and Qualcomm.
Dish recorded 200 Mbps uplink peak speeds with just 35 megahertz of 5G spectrum, and its network executed 1.3 Gbps downlink peak speeds with just 75 megahertz of 5G spectrum, both across FDD bands n71, n70 and n66. Compared to Time Division Duplex (TDD), which is another spectrum usage technique and uses a single frequency for both uplink and downlink, FDD uses separate frequencies for the uplink and the downlink, and in general, is considered better for coverage.
