5G Technology World and EE World present our first 5G handbook, digital edition.
Dynamic spectrum sharing of 5G and LTE networks addresses the need for spectrum, particularly at mid-band frequencies. Here’s how it works.
Performing these three steps can improve mmWave and beamforming performance.
Engineers designing 5G base stations must contend with energy use, weight, size, and heat, which impact design decisions.
To meet 3GPP specifications, a 5G New Radio (NR) implementation must meet demanding processing requirements and RF capabilities. Compared to LTE, this results in a need for higher performing, more flexible 5G NR hardware. Looking at 5G’s technical challenges, we see the frequencies and spectrum supported now include a sub-6 GHz range, FR1, with bandwidths…
Over-the-air testing requires different antenna setups for 5G FR1 and FR2. Temperature is a significant factor in calibration and validation.
Designing an antenna into a wireless embedded or IoT device requires special care to maximize performance.
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…
The laws of physics work against RF engineers, forcing design tradeoffs in mmWave systems. Beam steering, frequency reuse, and greater spectral efficiency can help.
Compared to 4G and previous generations, 5G’s mmWave frequencies and tight integration increase the complexity of both performance and regulator compliance testing.
