Intel FlexRAN™ gets boost from AT&T; faces competition from Marvel, Qualcomm, and EdgeQ for Open RAN silicon
Dell’Oro Group estimates the RAN market is currently generating between $40 billion and $45 billion in annual revenues. The market research firm forecasts that Open RAN will account for 15% of sales in 2026. Research & Markets is more optimistic. They say the Open RAN Market will hit $32 billion in revenues by 2030 with a growth rate of 42% for the forecast period between 2022 and 2030.
As the undisputed leader of microprocessors for compute servers, it’s no surprise that most of the new Open RAN and virtual RAN (vRAN) deployments use Intel Xeon processors and FlexRAN™ software stack inside the baseband processing modules. FlexRAN™ is a vRAN reference architecture for virtualized cloud-enabled radio access networks.
The hardware for FlexRAN™ includes: Intel® Xeon® CPUs 3rd generation Intel® Xeon® Scalable processor (formerly code named Ice Lake scalable processor), Intel® Forward Error Correction Device (Intel® FEC Device), Mount Bryce (FEC accelerator), Network Interface Cards – Intel® Ethernet Controller E810 (code name Columbiaville). Intel says there are now over 100 FlexRAN™ licensees worldwide as per these charts:

FlexRAN™ got a big boost this week from AT&T. In a February 24, 2022 blog post titled “Cloudifying 5G with an Elastic RAN,” Gordon Mansfield, AT&T VP Mobility Access & Architecture said that “AT&T and Intel had co-developed an industry-leading advanced RAN pooling technology freeing 5G radios from the limitations of dedicated base stations, while enabling more efficient, resilient, and green 5G networks. DU-pooling will eventually be usable by the entire 5G operator community to drive the telecom industry’s goals of green and efficient wireless networks forward.”
DU pooling technology was made possible by combining AT&T’s deep knowledge of Open RAN technologies as one of the co-founders of the O-RAN Alliance with Intel’s expertise in general purpose processors and software-based RAN through its FlexRAN™ software stack running on Intel 3rd generation Intel® Xeon® Scalable processors. The open standards for communications between radios and DUs that were published by O-RAN enabled its development, and the result is a technology demonstrator implemented on FlexRAN™ software.

Intel is now facing new Open RAN competition from several semiconductor companies.
Marvell has just unveiled a new accelerator card that will slot into a Dell compute server (which uses x86 processors). Based on a system called “inline” acceleration, it is designed to do baseband PHY layer processing and do it more efficiently than x86 processors. A Marvell representative claims it will boost open RAN performance and support a move “away from Intel.” Heavy Reading’s Simon Stanley (see below) was impressed. “This is a significant investment by Dell in open RAN and vRAN and a great boost for Marvell and the inline approach,” he said.
Qualcomm, which licenses RISC processors designed by UK-based ARM, has teamed up with Hewlett Packard Enterprise (HPE) on the X100 5G RAN accelerator card. Like Marvel’s offering, it also uses inline acceleration and works – by “offloading server CPUs [central processing units] from compute-intensive 5G baseband processing.”
There is also EdgeQ which is sampling a “Base Station on a Chip” which is targeted at Open RAN and private 5G markets. Three years in the making, EdgeQ has been collaborating with market-leading wireless infrastructure customers to architect a highly optimized 5G baseband, networking, compute and AI inference system-on-a-chip. By coupling a highly integrated silicon with a production-ready 5G PHY software, EdgeQ uniquely enables a frictionless operating model where customers can deploy all key functionalities and critical algorithms of the radio access network such as beamforming, channel estimation, massive MIMO and interference cancellation out of the box.
For customers looking to engineer value-adds into their 5G RAN designs, the EdgeQ PHY layer is completely programmable and extensible. Customers can leverage an extendable nFAPI interface to add their custom extensions for 5G services to target the broad variety of 5G applications spanning Industry 4.0 to campus networks and fixed wireless to telco-grade macro cells. As an industry first, the EdgeQ 5G platform holistically addresses the pain point of deploying 5G PHY and MAC software layers, but with an open framework that enables a rich ecosystem of L2/L3 software partners.
The anticipated product launches will be welcomed by network operators backing Open RAN. Several of them have held off making investments in the technology, partly out of concern about energy efficiency and performance in busy urban areas. Scott Petty, Vodafone’s chief digital officer, has complained that Open RAN vendors will not look competitive equipped with only x86 processors. “Now they need to deliver, but it will require some dedicated silicon. It won’t be Intel chips,” he told Light Reading in late 2021.
…………………………………………………………………………………………………………………………………………………………………………………………………………………………..
Inline vs Lookaside Acceleration:
While Marvell and Qualcomm are promoting the “inline” acceleration concept, Intel is using an alternative form of acceleration called “lookaside,” which continues to rely heavily on the x86 processor, offloading some but not all PHY layer functions. This week, Intel announced its own product refresh based on Sapphire Rapids, the codename for its next-generation server processors.
Simon Stanley, an analyst at large for Heavy Reading (owned by Informa), said there are two key innovations. The first involves making signal-processing tweaks to the Sapphire Rapids core to speed up the performance of FlexRAN™, Intel’s baseband software stack. Speaking on a video call with reporters, Dan Rodriguez, the general manager of Intel’s network platforms group, claimed a two-fold capacity gain from the changes. “In the virtual RAN and open RAN world, the control, packet and signal processing are all done on Xeon and that is what FlexRAN enables,” he said.
The other innovation is the promise of integrated acceleration in future Sapphire Rapids processors. Sachin Katti, who works as chief technology officer for Intel’s network and edge group, said this would combine the benefits of inline acceleration with the flexibility of x86. That is preferable, he insisted, to any solution “that shoves an entire PHY layer into an inflexible hardware accelerator,” a clear knock at inline rivals such as Marvell and Qualcomm. Despite Katti’s reference to inline acceleration, Stanley does not think it is Intel’s focus. “None of this rules out an inline acceleration solution, but it does not seem to be part of the core approach,” he told Light Reading. “The key strategy is to add maximum value to Xeon Scalable processors and enable external acceleration where needed to achieve performance goals.”
Both inline and lookaside involve trade-offs. Inline’s backers have promised PHY layer software alternatives, but Intel has a major head start with FlexRAN™, which it began developing in 2010. That means lookaside may be a lot more straightforward. “The processor is in control of everything that goes on,” said Stanley during a previous conversation with Light Reading. “It is essentially the same software and makes life very easy.”
Larger network operators seemed more enthusiastic about inline during a Heavy Reading survey last year. By cutting out the processor, it would reduce latency, a measure of the delay that occurs when signals are sent over the network. That could also weaken Intel, reducing power needs and allowing companies to use less costly CPUs. “If you use inline, you probably need a less powerful processor and less expensive server platform, which is not necessarily something Intel wants to promote,” Stanley said last year.

On the network equipment side, Samsung Electronics recently won a 5G contract with Japanese telco NTT DOCOMO, as it seeks to challenge incumbents like Huawei, Ericsson, and Nokia in the telecom equipment business, according to media reports.
In India, Samsung Electronics is likely to apply for a production-linked incentive (PLI) scheme for telecom equipment manufacturing, benefiting from India’s program to locally make 4G and 5G gear and other equipment – for sales both in India and overseas, ET recently reported.
Samsung would then join other global manufacturers such as Cisco, Jabil, Flex and Foxconn, besides European telecom equipment vendors Nokia and Ericsson in applying for the PLI scheme that seeks to boost local production of telecom equipment and reduce imports.

Analysis by Zacks Equity Research:
Nokia has long struggled to undertake additional investments related to its 5G powered ReefShark SoCs. These SoCs are best known to leverage a single computer chip to operate an entire system. Unfortunately, its inability to develop ReefShark portfolio has hindered its cost-efficiency feature, compromising its profitability to rivals like Ericsson ERIC, which spends hefty amounts on R&D. Dearth of resources and geared up 5G spending cycle have also put Nokia at the risk of losing out on upcoming commercial launches.
The latest collaboration comes as a savior for the Finnish company to cater new vertical markets especially in the face of burgeoning network traffic and dynamic 5G plans. Dubbed as a key partnership, it is expected to reduce Nokia’s technical disparities and address the complex requirements of 5G NSA, SA, NR specifications for future 5G network deployments.
Nokia’s gross margin was negatively impacted by a high cost level associated with its first generation 5G products, product mix and profitability challenges in China. Despite a 4.2% rise in revenues in third-quarter 2019, the performance was marred by pricing pressure in early 5G deals and temporary capital expenditure constraints in North America related to the proposed merger of T-Mobile US and Sprint. This was followed by its decision to suspend dividend payments and slash guidance for 2020. The company has also decided to retrench about 180 employees in order to trim operating costs.
It remains to be seen whether Nokia will be able to script a turnaround amid a challenging macroeconomic environment and geopolitical uncertainties.
