MWC 2021: Qualcomm Demos Enhanced Wide-area 5G OTA Testbeds

In this MWC 2021 demo, we showcase how Qualcomm is pushing the boundaries of 5G, with recent upgrades to our wide-area 5G OTA test network in San Diego. This multi-cell system operates in the 3.5 GHz spectrum with 100 MHz bandwidth, supporting two gNodesBs with advanced multi-user massive MIMO and 5G NextGen Core.

Qualcomm is taking another step closer to 5G full-duplex. Our 5G OTA test network can now support subband half-duplex, which enables dynamic TDD operation and allows for more flexible service multiplexing as well as improved latency and coverage.

The second demonstration in this video shows our prototype of single-cell and multi-cell 5G positioning in a joint OTA effort, which showed that it can meet 3GPP Rel-16 accuracy targets. In parallel, we also used our own test network to showcase the benefits of machine learning (ML) and sensor fusion for 5G positioning.

Qualcomm is constantly working to push the boundaries of 5G technologies. Through its investments in cutting-edge deployments and designs, Qualcomm is demonstrating how to go beyond the boundaries of data communications.
