Hyperscalers, Open RAN, Private 5G and chip announcements were top news at the MWC show in Barcelona last week. Based on disclosures at the show, Open RAN looks to go commercial in 2023 and 2024, hyperscalers are obtaining contracts to carry an increasing amount of telecom-related workloads, Rakuten Symphony is amassing a growing list of partners, Qualcomm/Marvell and other chip companies are taking front-stage at MWC, and there were a variety of new private 5G-related announcements including those from Cisco, Huawei, Mavenir and Federated Wireless. We took some time to compile some of the most noteworthy announcements, sorted by company.
DISH chairman says 5G deployment is 6 months behind schedule. DISH says it fell behind on a technical level and that it realized it has to become the systems integrator. Expects to light up 25 metro regions in June, representing 20% population coverage. Huawei is pivoting towards fiber in certain markets like the home market. It announced, for instance, Fiber to the Room (FTTR) and contrasted it to Wi-Fi which it claims has a variable experience. Huawei's wireless Chief, Ryan Ding, keynote speech noted several points. By the end of 2021, Huawei signed more than 3,000 commercial 5GtoB contracts with Chinese operators and partners for industry applications (implies operators involved in all), including coal mining using remotely controlled shearers communicating over 5G. Mavenir showcased End-to-End 5G Core, IMS and automation hosted on AWS. The company calls this a "pilot" and asserted that using a core on AWS system would reduce TCO and speed up rollouts. Mavenir also announced 5G Radio Units from 8T8R to 64T64R (Massive MIMO) that use Qualcomm chips and that it plans to develop vDU RAN software based on the Qualcomm X100 5G RAN Accelerator Card, both systems of which are expected to be available for global deployment in 2023. Telefonica advocated for OpenRAN and explained its selection of technology suppliers such as radio/RRU/AAU (NEC, Comba, Airspan), Baseband (Altiostar/Rakuten Symphony), Small Cell (Node-H, Askey, Qualcomm), RIC (Nokia), as well as Intel, Mavenir, Parallel Wireless, IBM/Red Hat and VMWare. It says it selected NEC as the systems integrator. The pan-European operator said that Open RAN reduced vendor lock-in and is most cost-efficient over the medium/long term, however suffers from integration with OSS and the time to carry out interoperability tests until Open RAN is mature. It expects Pilots to continue during 2022, then initial deployments in 2022/2023, followed by "massive deployments" beyond 2023 (we think this means 2024). Rakuten Symphony announced it had acquired San Jose, CA based Robin.io, an automation and orchestration software company. Rakuten Symphony also announced an Open RAN trial at MTN that includes Accenture and Tech Mahindra. Symphony also said AT&T will use Rakuten's Site Manager, a software system that designs workflows for network deployments; additionally, AT&T's proprietary capacity planning tool. Cisco and Rakuten announced a partnership described as a joint go-to-market model. Nokia is Rakuten's first "Symworld" partner, whereby Nokia's core software will be made available to Symphony customers. Qualcomm. Made announcements about private 5G automation, a partnership with Microsoft about Private 5G, Mavenir portfolio expansion (also discussed elsewhere in this article), Fujitsu mmWave, and 5G FWA. Orange announced plans to use Ericsson 5G SA core for Belgium, Spain, Luxembourg and Poland, Nokia 5G SA core for France and Slovakia and Oracle for 5G core signaling in all countries. It plans to launch SA commercially in 2023. Microsoft Azure announced Operator Distributed Services, which is a combination of its 2021 acquisition of AT&T Network Cloud Services and Azure for Operators tools. The company explains that it will enable operators to run all their workloads, including RAN, core, mobile and voice core, OSS and BSS, on a single carrier-grade hybrid platform. Microsoft also announced that AT&T is integrating its 5G network with Microsoft Azure Private Multi-access Edge (MEC) computing to develop AT&T Private 5G Edge. Telstra collaborates with Ericsson and Microsoft to begin 5G-enabled edge compute trials. Cisco announced ORAN partnerships with private 5G vendors like Airspan and JMA Wireless and said it is in customer trials with both vendors. As it had said a month earlier with its private 5G launch, this is being offered as a subscription service operated by Cisco, and Cisco will allow customers to use their own brand to market the service. Cisco announced it is on a variety of Private 5G projects including at Chaplin, Clair Global, Colt Technology Services, ITOCHU Techno-Solutions Corporation, Maderia Island, Network Rail, Nutrien, Schaeffler, Group, Texas A&M, Toshiba, Virgin Media O2, and Zebra Technologies. ZTE announced lighter Massive MIMO radios, its UniSite NEO and a new "Gen 2" FWA CPE based on Qualcomm Snapdragon X65 and X62 5G Modem-RF platforms. Marvell announced 5G-related product line enhancements, including a reference design with DELL technologies that creates a server based baseband processing system.

In conjunction with its recent Rakuten earnings call this week, Rakuten Mobile disclosed some more of its plans. This mobile operator is becoming a telecom vendor. Specifically, it said that “by expanding the Rakuten Communications Platform (RCP) globally, Rakuten aims to evolve from a Japan-headquartered tech company to a global leader in telecom.” We see this as an explicit statement that the company plans to sell its telecom software and related services to operators worldwide. For instance, Rakuten Mobile just announced a partnership with Saudi-based operator, stc. This move pits Rakuten against Microsoft (who just acquired telecom companies and runs a cloud), Oracle (who runs a cloud and made telecom company acquisitions), and the rest of the telecom industry (traditionally Nokia, Ericsson, Huawei, ZTE, Amdocs, Netcracker and others).
In offering RCP to other operators around the world, its unique value, as we see it, is that Rakuten has successfully built an LTE and now a 5G network based on Open RAN. What we find interesting is that the company has developed a significant amount of intellectual property in-house or through technology sharing. In an interview today with Tareq Amin, Rakuten Mobile executive, we asked what technology has been developed in-house by Rakuten. Here’s what we learned.
Some other components are not developed by Rakuten (the radios come to mind), but this is an exciting development. RCP would be delivered as a “private cloud” on the premises of carrier customers (partners). The terminology Rakuten is using for this “private cloud,” is it’s a “pod.” RCP’s plans are a very interesting development in the industry. There is one more thing. Rakuten said it is working with a technology supplier that will sell Rakuten a server card that would allow a combined router and RAN processing function to co-exist on a server. Today, the servers it uses to support its Open RAN radios use an FPGA NIC. These servers can support up to 16 base stations. We see the addition of routing to this card as an extension of the capability – but it means there may be a diminished need for cell site routers.  Before the consolidation in the Mobile Radio Access Network (MRAN) market that occurred in the past decade during Huawei’s ascendancy, there were a dozen major RAN vendors. They included Motorola, Lucent, Alcatel, Siemens, Nokia, Ericsson, NEC, Fujitsu, Samsung, Nortel, Huawei and ZTE, and they hailed from the US, France, Germany, Finland, Sweden, Japan, Korea, Canada and China. As Huawei entered the market, using a price aggressor strategy, it catalyzed mergers, resulting in the elimination of Motorola, Lucent, Alcatel, Siemens, Nortel, plus a reinforcement that led to the Japanese and Korean players to sell primarily to their home markets. The result is that in many markets during recent years, there were only two vendors left, and that left operators with little choice but to look elsewhere. The punchline is that going forward, due in part to Open RAN, and in part to the response of operators looking outside their traditional supplier base, we now have 10 RAN players who can bid on projects. And there is a multiplier on top of the 10 players, because going forward, operators can buy radio heads from different vendors than their primary RAN baseband vendor, essentially doubling the number of choices an operator has when making mobile RAN vendor decisions. Here is how we arrive at the conclusion that there were only two players per major geography. Just a couple years ago, the state of affairs was quite different; we had only Nokia, Ericsson, Huawei and ZTE as players, and last year, it became clear that in the US, only two major players were left. In China, the same could be said, with Huawei and ZTE as main suppliers (Ericsson has won business there and Nokia ceded the market in 2019). And in 2020, we’ve seen much of Europe and English-speaking Asia whittle down to two suppliers, as well. And here is how the procurement teams at operators have much choice in the future. The “Open RAN” vendors are now deemed viable given the success at Rakuten and the push by operators to demand Open RAN compliance, and these include Altiostar, Mavenir and Parallel Wireless. Nokia and Ericsson are invited to most, if not all bids worldwide. Huawei and ZTE are invited to many, but a declining number of bids in markets that are siding with the US viewpoint. We saw a turning point in late 2018 when AT&T announced it will buy from Samsung, who has now gotten a strong foothold in both India and the US. And, more recently, we have seen two Japanese players, NEC and Fujitsu, in some way filling in the void left by Huawei and ZTE’s woes in the US/China spat, as they get wins (Fujitsu recently won DISH) and get invited to bid (NEC and Fujitsu are being asked to bid on UK projects). Add these up and we have Altiostar, Mavenir, Parallel Wireless, Nokia, Ericsson, Huawei, ZTE, Samsung, NEC, Fujitsu. There are other factors at work that are adding to more RAN choices, as well. Two such trends are Facebook’s efforts, ONF’s efforts and the variety of radio head vendors who are now viable with Open RAN/FB/ONF efforts. Facebook has promoted projects such as Telecom Infra Project (TIP) that have many goals, including one that supports the goal of $1,000 radio heads (these cost much more from the major vendors). The Open Network Foundation (ONF) supports projects such as SD-RAN and Aether. Radios can be purchased from non-traditional sources, as well because with all three projects we have mentioned above (TIP, ONF SD-RAN and Open RAN), these allow radio purchases to be made separately from baseband purchases, literally doubling the choices that operators have when building out a roster of vendors. The trends in mobile RAN have changed significantly. Vendors with little to lose (startups and players entering new markets) are getting aggressive to grow their businesses. Incumbent vendors are at risk, as their business practice of selling baseband and radio simultaneously to captive operators is coming to an end. We may look back at this early 5G era and say there was a lot more to it than just the upgrade to 5G, and it begs the question, who will acquire whom to consolidate the market once again and get pricing under control. We review the new announcements Cisco made public for the now-cancelled MWC20 show, and they are: BNG on unified control plane, Unified Domain Center-to-DNA Center interoperation, IoT Control Center, SP Services Edge (CDN), new Open RAN partners, NCS 540 router with CPRI support, and Crosswork automation platform. Since MWC is a show primarily focused on mobile and wireless, we think the two announcements that are most “wireless” in nature were: (a) Unified Domain Center announcement, which will unify management of WiFi to cellular operator LTE is interesting and (b) the partnerships Cisco announced with Open RAN vendors like Parallel Wireless, NEC and World Wide Technology.

Keynotes at the NFV World & Zero-Touch Congress in San Jose, California were very interesting today. We share our observations and view of the main themes from these interesting presentations by Nokia, NEC/Netcracker, Google, CenturyTel. The main theme of these presentations, we think, is this: NFV/SDN is now deeply in the deployment and commercial phase, where compared to 3-4 years ago, it was just a concept. Nokia. The company announced that its Airframe server platform, which is an OCP based design, comes available with either embedded acceleration or pluggable acceleration. This comment includes its software acceleration. The company explained that its Reefshark chipset can be equipped on the Airframe server and can perform better than a non-accelerated server:
In explaining functions that an Airframe with Reefshark can perform, the company gave a good example: massive MIMO beamforming can be assisted by the machine learning capabilities.  Nokia's Henri Tervonen at NFV and Zero Touch World Congress NEC/Netcracker. Enrique Gracia presented several uses cases of the NEC/Netcracker customers that related to NFV/SDN. He explained that 16 customers have deployed one or more of these uses cases. Full Stack OSS/BSS/MANO. A customer deployed this system in 12 weeks to launch a VNF. The system managed both physical and virtual devices. Expand to a new territory using VNFs from home region. A customer now delivers services to a customer outside the home territory by deploying the software and service from the network location at the home location. In this particular case, NEC/Netcracker and its customer do revenue sharing and VNFs include SD-WAN, virtual firewall and others. The service provider is expected to expand its customer addressable base by 40%, mainly targeting small/medium businesses in this non-home region. This system uses MANO, OSS, BSS and the marketplace. The company says in this case, time to revenue is expected to take 50% less time to deploy new VNFs in the future. uCPE (Universal Customer Premises Equipment) deployment instead of branded hardware. The company worked with a service provider company to enable uCPE to be deployed as an alternative to Cisco, Juniper and others' gear.  Enrique Gracia of NEC/Netcracker at NFV and Zero Touch World Congress Google Cloud. Vijoy Pandey, who represented Google Cloud, presented on the topic of using AI/ML to reconfigure its data center system. The company's cloud data center architecture has been evolving continuously since it was first introduced. Currently, the company is using its own AI/ML system to learn from current network traffic patterns in order to design its future network architecture.  Vijoy Pandey, Google Cloud, presenting at NFV and Zero Touch World Congress CenturyTel. The company has deployed Broadcom based Ethernet switches using its own Network OS. These switches do their own packet forwarding. Additionally, the company has built its own orchestration system called VICTOR. It draws upon Ansible, NetCONF, uses the service logic interpreter from ONAP and uses parts of Open Daylight. The company plans to open source this development and the spokesperson Adam Dunstan said, perhaps jokingly, that this might be called ONAP-lite.
