GPS and GNSS have been the standards for network timing, but they have security issues. A Master clock and IEEE 1588 reduces the risk and lowers installation costs. Global Navigation Satellite Systems (GNSS) provide the critical primary reference clocks that networks need to correctly operate and seamlessly coordinate the flow of voice, data and…
5G fronthaul networks add flexibility
Flexibility in network control and distribution has created the need for separating the functions between wireless and wired network equipment. To deliver on the promise of 5G, which sometimes seems like everything to everyone, network operators will need to augment their existing network architectures, addressing some flexibility brought into existence with the new 5G technologies…
How 5G changes the V2X communications game
The concept of vehicle-to-everything (V2X) communications has been around for 20 years. So far, V2X has achieved limited uptake for several reasons. That’s about the change with the widespread deployment of 5G technology. The 5G new radio (NR) standards contain several innovations that will change the game for V2X technology, saving lives, reducing fuel consumption,…
5G does not spread biological viruses
Misinformation is getting out of hand. 5G is not the problem, people are. Over the last day, several people have emailed me about reports coming from the UK of people destroying cell towers. Indeed, it’s all over the news media as misinformation spreads that 5G is spreading the coronavirus. The belief that 5G is responsible…
Spectrum analyzers for mmWave engineers use oscilloscope front ends
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…
Ericsson’s spectrum sharing slices frequencies in time
Spectrum sharing of LTE and 5G equipment conserves bandwidth and eases the path to 5G. Demand for wireless services continuously increases. With 5G still under construction, it’s not ready to relieve LTE networks of the burden. Thus, engineers keep developing clever ways to get more from available spectrum, especially in the crowded FR1 (below 6…
Optical networks gear up for 5G
5G is bringing higher bandwidth to mobile users, which pushes more data on the optical networks. Optical networks need greater capacity and more flexibility. Every mobile phone user expects 5G to let them download movies faster and more reliably than LTE networks. Plus, 5G will open the door to new use cases we haven’t conceived…
COVID-19 forces three-month delay in 3GPP releases
3GPP the standards body for wireless standards, has delayed the adoption of the next two releases (Release 16 and Release 17) each by three months. The delay is in response to the COVID-19 virus. 3GPP Release 16 stage 3 freezing will now occur in June 2020 while Release 17 will now be frozen in June…
5G is hot, keep your components and systems cool
5G’s antennas and the devices that drive them generate more heat than their LTE predecessors. That creates now cooling problems for wireless devices and systems. If you listen to and read all 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…
OFC plenary: 5G will drive optical
China Telecom’s Qi Bi told optical engineers how 5G will change their lives, and ours. 5G is more than wireless. Included in the 5G chain is fiber, lots of it. After all, how will all those mmWave small cells connect to the wired network? Thus, 5G should keep optical engineers busy for years, but only…
