5G Technology World

A report by Information Gatekeepers (IGI Group) says that the two largest U.S. carriers are not spending enough on 5G rollout. That’s what author Clifford Holliday told 5G Technology World. In Analyst: 5G is all about the traffic, telecom industry analyst Clifford Holliday explained how 5G must acquire the traffic from 4G LTE because LTE…

5G’s antennas and the devices that drive them generate more heat than their LTE predecessors. That creates new cooling problems for wireless devices and systems. If you listen to and read the hype surrounding 5G, you’ll come away thinking that 5G is truly hot. That’s the marketing perspective. From an engineering design perspective, 5G is…

The Tektronix RSA7100B wideband RF signal analyzer and streaming recorder lets engineers working on wideband designs in communications, radar, and electronic warfare capture and analyze signal in the frequency domain. It provides more than 2.5 hours of streaming RF storage with 800-MHz real-time bandwidth. Its 16 kHz to 26.5 GHz frequency range covers a broad…

In Digital modulation basics, part 1 we examined the concept of quadrature modulation and signal generation. We showed a common block diagram for generating a quadrature signal (Figure 1). There is a corresponding receiver block diagram to extract the Inphase (I) and Quadrature (Q) components of the signal (Figure 2). The signal is converted to…

Keysight Technologies has created a slim version of its high-bandwidth oscilloscopes for analyzing wireless signals, including 5G NR. When you think of high-bandwidth oscilloscopes, you may think that their sole use is for measuring the integrity of baseband digital signals—in the time domain. RF engineers typically work in the frequency domain using swept or real-time…
