Private networks present a number of challenges for testing and assurance. By their nature, private networks are delivering some type of service aspect that cannot be achieved via the public network, whether that be more secure access, targeted coverage, or more sophisticated features such...
A new survey of enterprises interested in adopting private networks lays out two primary reasons that they want to do so—and it's not driven by vertical-specific, high-performance use cases.
Instead, they see the primary value of private networks as providing increased security and network...
PIM is an escalating issue in 5G midband networks deployed in TDD spectrum
Passive intermodulation is interference that is generated when two or more simultaneous signals interact in a nonlinear environment, where passive components (as opposed to transmitting ones) can cause new, unwanted signal noise...
Keysight Technologies said that it has received Global Certification Forum approval for the first validated test cases for 5G New Radio Release 16 power-saving features; specifically, demodulation and radio resource management (RRM) in Band n78 (3.5 GHz).
