The Open Networking Foundation (ONF) has launched a ‘Software-Defined Radio Access Network’ project aimed at developing open-source RAN solutions using an ‘app store’ model for network optimization features.
This effort will be helped by the open RAN (ORAN) and virtual RAN (vRAN) movements now gaining steam, but it will also confront some of the same hurdles facing open RAN – including opposition from incumbent major vendors.
• Dynamic spectrum sharing (DSS) can improve the coverage and capacity of 4G/5G networks by allowing both technologies to efficiently share the same finite, licensed spectrum.
• Spectrum-sharing goes beyond 4G/5G, including 2G and 3G and potentially Internet of Things technologies, increasing its value and diversity.
As the 5G era dawns, a technology known as DSS has become a hot topic. DSS allows operators to use the same spectrum bands simultaneously for different radio access technologies. Specifically, the industry’s 3GPP standards enable using 4G and 5G in the same spectrum. It’s “dynamic” in that the network is continually re-evaluating user activity and reallocating spectrum to 4G and 5G traffic as needed – sometimes as often as every millisecond.

Enterprise RAN vendors CommScope and Dali each won damages in countervailing patent infringement cases last week, but an injunction against two Dali products may be of interest to the broader industry.
That injunction is suspended pending appeal. It may be rendered moot by expiring patents, and its impact may be mild even if upheld. Still, additional suits could foster lingering uncertainty in this space.
A legal battle over patent infringement between enterprise RAN vendors CommScope and Dali Wireless came closer to resolution last week, but a key aspect – an injunction that would prevent Dali from selling two primary products – remains uncertain. A Dallas judge upheld a jury verdict rendered last year that awarded damages to both companies in a patent infringement suit and related countersuit. CommScope was ordered to pay almost $9.5 million, plus additional interest, and Dali was ordered to pay about $6 million, plus interest.

• In their first round of quarterly results since the widespread outbreak of COVID-19, network operators provided few specifics on the true impact of the pandemic on 2020 outlooks.
• Most operators remain hopeful that a fuller picture of the impact of the disease will emerge in time for Q220 earnings releases, but that is likely to vary significantly by region and country.
With most of the world’s largest network operators now having chimed in on Q1 2020 earnings, what is clear is that little remains clear in terms of how COVID-19 will impact them this year. Most operators have withdrawn full-year guidance and have indicated that a reliable picture will not emerge until the true trajectory of COVID-19 becomes clear. Since that answer can vary significantly from country to country, region to region, and city to city, most operators lack the tools to provide reliable guidance.

• Nokia has been excluded from the latest wave of 5G RAN rollouts by major Chinese mobile operators
• Though Nokia has strategies to overcome this obstacle, the underlying trends of geographic polarization don’t bode well for the industry.
Reporting its Q1 2020 earnings today, Nokia acknowledged that it has essentially been shut out of the Chinese 5G RAN market – the largest such market in the world.
This news didn’t come as a shock to anyone who had seen recent reports that – despite a fresh deal to supply China Unicom with a 5G core platform – Nokia was not named as a supplier in the latest wave of 5G RAN contracts awarded by China’s three major mobile operators. As usual, these procurements went mostly to China’s two major equipment vendors, with Huawei earning the lion’s share, and ZTE’s much smaller share still towering over that awarded to Sweden-based Ericsson.

Ericsson provided the most level of detail yet on the steps it has taken, both internal and customer-facing, in the wake of COVID-19.
Advanced planning emerges as a key feature of Ericsson’s approach, helping drive a number of important steps that should serve as a template for managing future crises.
As it released its first earnings report since COVID-19 began its rapid global spread, Ericsson took the opportunity to outline the various steps it has taken, both internally and externally, to plan for the known impacts and to predict the unknown effects. The actions taken by the company, which was one of the earliest to make the difficult decision to withdraw from this year’s MWC event in Barcelona, should serve as a case study for ‘how to get it right’ in the case of a crisis. For example: Continue reading “COVID-19: Ericsson’s Proactive Approach Serves as a ‘How To’ in Crisis Management”→
The COVID-19 pandemic could accelerate investment in wireless solutions for the digital, ‘big data’ transformation of enterprise verticals sometimes called ‘Industry 4.0.’
Changes made in response to both social distancing and recession-induced workforce reductions could last long after the threat of the virus subsides.
The COVID-19 global pandemic is already expected to transform society in fundamental and irrevocable ways that we can’t yet fully predict. One effect of this transformation may be to accelerate initiatives to deploy cellular network technologies, such as LTE and 5G, to fundamentally reorder industrial operations across a range of enterprise verticals. This trend is already underway, as enterprises investigate the benefits of wireless networks that provide more reliability, and lower latency, than WiFi. However, the sudden and severe disruption that COVID-19 has wrought could force near-term changes among enterprises that lead to lasting practices. For example: Continue reading “COVID-19 Could Accelerate Wireless Industry 4.0”→
• The COVID-19 pandemic is likely to increase demand for fixed wireless access (FWA) solutions to fill gaps in fiber broadband networks.
• 5G FWA has a mixed reputation but is improving; meanwhile, LTE-based FWA may be useful for serving some immediate needs
The COVID-19 global pandemic has resulted in a sudden and widespread explosion in telecommuting, as countless employees who can work from home now do. In many cases, these new telecommuters are using live videoconferencing tools that are sharing home-broadband bandwidth with children who have been sent home from school. The result is a sharp increase in home broadband needs. Where residences have access to fiber, these capacity needs may not be hard to meet. But fiber doesn’t reach every residence; any number of obstacles – including geographical or regulatory ones, or even sheer distance – might get in the way. Thus, demand is likely to increase deeply for fixed-wireless access solutions to fill in the gaps in fiber broadband networks.

• Huawei promoted several new RAN solution launches at an event held in London this month, including a Super Uplink solution for increasing 5G network capacity and radios utilizing 400 MHz of bandwidth.
• Huawei also emphasized the value of both frequency- and time-division spectrum.
At an event held February 20 in London, Huawei updated press and analysts on its latest 5G moves. The vendor cited its ability to provide end-to-end solutions for 5G networks, including RAN, core, and Multi-Access Edge Computing, which helps deliver 5G’s low-latency requirements. This comprehensive approach could also enable more cohesive network slicing, a key capability for enabling 5G’s ultimate value proposition.
The UK government has proposed limits in how much Huawei 5G RAN gear mobile operators deploy.
Exactly how operators will implement those limits is unclear, raising several questions.
The National Cyber Security Centre (NCSC), the UK’s technical authority on cybersecurity, made big headlines this week by issuing recommendations for UK operators regarding how to honor national security concerns in selecting 5G network suppliers. But, beyond the headlines – primarily regarded as a win for Huawei, since the NCSC allowed a role for Huawei in UK 5G networks despite pressure from the U.S. – the NCSC’s actions raise plenty of questions about how UK operators will source, plan, and deploy their 5G radio access networks (RANs).
