Basic RF measurements go a long way toward characterizing today’s communication systems.

Software-defined radio addresses problems and limitations found in hardware-based radios, such as hardware obsolescence and rigidity.

Mobile phones are still phones. 5G devices need the ability to fall back to LTE when network voice support isn’t available. Here’s how and why.

As frequency increases, the effects of PCBs gain in importance for signal fidelity. Specifying PCB material, signal power and return planes, and signal layout all play a role.

IEEE 1588 PTP and SyncE protocols keep radio units, switches, and distribution units in sync.

The open standards for radio access networks offer options for locating network functions. These functional split options depend on network services and available transport links.

If properly architected, there’s now a world of applications in which AI enables 5G, and a world where 5G enables AI, all collapsed in a transparent manner for enterprise, telco, and the edge. 5G brings wireless convenience combined with the speed and reliability of wired connections as where AI brings unprecedented intelligence to machines through…

Engineers designing 5G base stations must contend with energy use, weight, size, and heat, which impact design decisions.

The 5G mid-band spectrum offers a compelling balance of capacity and coverage necessary for new applications and use cases.

The 5G femto application platform interface (5G FAPI, or simply FAPI) published by the Small Cell Forum (SCF) is a suite of specifications that enable small cells to be built up piece-by-piece using components from different suppliers. It can be viewed as a subset of the network functional application platform interface (nFAPI), also published by…
