The 5G mid-band spectrum offers a compelling balance of capacity and coverage necessary for new applications and use cases.
What is 5G femto application platform interface (5G FAPI)?
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…
5 tips for designing with embedded antennas
Designing an antenna into a wireless embedded or IoT device requires special care to maximize performance.
Unlicensed spectrum use: What’s the technology behind it?
Unlicensed LTE lets wireless carriers offload traffic to Wi-Fi frequencies, but it must coexist with Wi-Fi and not interfere. Here’s how it works.
IoT: How 5G differs from LTE
5G extends its scope beyond consumer only to many new vertical and enterprise markets. Thanks to its flexibility and improved performance, 5G opens the door to many industrial applications. When researchers and engineers began developing 5G in 2012, they began to look at use cases. The primary motivation for launching a new generation of wireless…
mmWave signals: The effect on PCB traces, cables and connectors
The use of mmWave technology is growing across various applications, from 5G telephony to automotive systems and drones. At mmWave frequencies, signal integrity (SI) is a major concern. SI measures the signal’s ability to propagate without distortion or undue losses. It measures the quality, or distortion, of the signal passing through the printed circuit board…
How Doherty Amplifiers improve PA efficiency
An amplifier design from 1936 gets a revival by reducing power consumption in cellular radios.
Envelope tracking improves power amplifier efficiency
RF power amplifiers consume lots of energy, which is a concern associated with 5G. Envelope tracking helps reduce power consumption but has tradeoffs.
Why the 5G core converges wireless with wireline
A toolkit lets integrated operators run their mobile and fixed-line operations on a common 5G core.
How to calculate RF power amplifier efficiency
5G brings higher data rates and a need for more efficient power amplifiers. Understand and calculate a PA’s efficiency. Radio communication systems steadily improve data rates and overall system performance. With that higher performance comes increasing pressure on power consumption. A recent industry report [Ref 1] concluded that power consumed by a typical 5G base…
