China Broadcasting Network (CBN) has recently accomplished a significant milestone by successfully conducting field verification of crucial technologies for a 5G-A low-altitude private communication network in Shanghai. The burgeoning use of drones in logistics, inspection, emergency response, and cultural tourism has spurred a transformation in economic activities, shifting from traditional two-dimensional ground-based operations to dynamic three-dimensional low-altitude endeavors. This evolution necessitates advanced communication networks to support these new dimensions.

In response, China Broadcasting Network has introduced a cutting-edge 4.9GHz low-altitude private communication network solution, emphasizing "dedicated frequency, dedicated network, and exclusive use." Remarkably, the network's measured uplink speed surpasses 200Mbps, while the cell edge rate exceeds 25Mbps, effectively catering to business requirements such as the transmission of 4K ultra-high-definition video.

The verification process employed a 4.9GHz 128TRx AAU module with independent carrier-to-air transmission capabilities. By leveraging technologies like handover coordination and interference management, the solution tackles the challenges of fragmented coverage and frequent handovers inherent in low-altitude communications. This ensures that drones maintain uninterrupted connectivity to the low-altitude private network throughout their operational flights.
