The laws of physics work against RF engineers, forcing design tradeoffs in mmWave systems. Beam steering, frequency reuse, and greater spectral efficiency can help.
5G radios increase emphasis on compliance testing
Compared to 4G and previous generations, 5G’s mmWave frequencies and tight integration increase the complexity of both performance and regulator compliance testing.
Open RAN functional splits, explained
Open radio access networks offer the option of placing network functions in different places along the signal path. That option, called a functional split, lets network engineers optimize performance and make tradeoffs.
