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).

5G networks' density, increased bandwidth, and mid-band...
Passive intermodulation (PIM) 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 to be generated that impacts the performance of the RF system.
Why...
Broadband Forum has launched a new technical project focused on enabling 5G Fixed Wireless Access to more efficiently serve multi-dwelling units (MDUs) via the re-use of existing property infrastructure cabling.
Broadband Forum described several issues with using 5G FWA—particularly at mmWave frequencies, which provide the...
Verizon also took home Opensignal's first award for live video speeds via 5G
T-Mobile US continues to dominate 5G download speed and availability in Opensignal's rankings, but Verizon narrowly beat out T-Mo on 5G upload speeds and maintained its lead in performance in terms of...
Keysight Technologies is making the move to acquire real-time digital twin company ESI Group through a share buy-out which values the company at nearly $1 billion. The company said this week that it has already made a binding offer to some shareholders in order...
Open Radio Access Networks pose both an opportunity—for new flexibility and agility within the RAN and the ability for network operators to re-set vendor relationships—and a challenge of interoperability among freshly disaggregated network elements.
