Today, Alan Weckel participated in Intel's webinar on how technology is changing from the edge to the cloud. It was clear working on this project that the data center is rapidly innovating to next-generation technologies to keep pace with data growth. How will networks for communication service providers (CoSPs), cloud service providers (CSPs), and enterprises evolve to handle the dramatically increasing data volumes expected in the coming years? Increasing data volumes are being driven today by smartphones, laptops, IoT, and, in the near future, by emerging 5G-enabled services. 650 Group's internal projections indicate that data entering/exiting the data center (north/south) is driven mostly by consumer content (e.g., video). In contrast, a wide range of use cases ranging from enterprise applications, consumer data, and cloud applications drive data between machines.
As part of the webinar, we authored a white paper on how quickly technology is involving in the data center. As we did our end-user interviews during the last few months, we saw many advancements in technology to support the growth of data in the cloud. We are excited to see all the new announcements coming as we close out 2020 and enter 2021.

Ericsson has served the mobile service provider industry well over the years. Most devices connected to its customers’ networks are mobile phones; this, however, is changing. Internet of Things (IoT) devices are entering the fray and provide an avenue for growth, as is the enterprise market. Additionally, Ericsson’s channels have mostly been to operators, at a time when enterprise growth is expected to provide additional cellular industry growth. Ericsson’s portfolio, until the Cradlepoint acquisition, was not particularly well-positioned to benefit from IoT and enterprise growth vectors.
IoT devices come in all shapes and sizes, and they use a number of different connectivity methods, from cellular to Wi-Fi to Bluetooth to LoRa and many others. In 2020, we expect only 16% of IoT and wirelessly connected devices will connect to cellular systems; the rest connect to more popular (and mostly free) connectivity types. We see cellular connections growing in the future, but as a percentage of all IoT and wirelessly connected devices, we expect it will drop to 13% of all such devices five years from now. The reduction in the fraction of IoT and wireless devices connected to cellular is why the “cellular to other” gateway market (Cradlepoint’s main market) makes sense. There are some use cases where cellular backhaul connections to connect Wi-Fi, Bluetooth, Zigbee and others are vital.
With US-based CBRS and European nations’ private enterprise spectrum opening up the opportunity that enterprises will build their own networks – without needing a mobile operator’s help with sub-leasing licensed spectrum – the folks at Ericsson had a choice to make. The choice was to continue selling to and through mobile operators and hope that mobile operators keep their share of enterprise and IoT growth, or to acquire products and distribution channels to access enterprise growth.
Ericsson’s competitors were partnering with Cradlepoint with some success. Recently, Nokia’s enterprise revenues hit about 10% of revenues, in part because it was selling LTE gear to customers in verticals such as utilities, mining & exploration, and logistics & shipping. Many of these customers were using devices such as Cradlepoint’s. Ericsson is now invited to these ongoing dialogues as these networks expand and change.
We would be remiss if we didn’t mention 5G in relation to Cradlepoint. Some enterprises seek a secondary wireless connection to supplement their primary wired broadband connection. Gear such as Cradlepoint routers can serve this need well. In this sense, we can see why Ericsson uses messages such as “Ericsson accelerates 5G for Enterprise with the Cradlepoint acquisition.”
This acquisition is not without controversy, in our view. The Swedes are acquiring a company located in Boise, Idaho, and as such, managing from afar may present challenges. Cradlepoint sells its devices differently (mainly through channels) from how Ericsson sells its gear (mainly direct); these two distribution methods may conflict. Ericsson sold its cell phone business many years ago because it conflicted with its mobile infrastructure business. Similarly, Cradlepoint gear is focused mainly on enterprises, we see a similar conflict because Cradlepoint’s customer base liked its independence from cellular gear-makers. If Ericsson can manage through these challenges, it may enjoy exposure to IoT, enterprise and 5G gateway growth opportunities.
Alex Choi, SVP, Head of Strategy and Technology Innovation at Deutsche Telekom, presented at Day 2 joint keynote broadcast for ONF's Spotlight event on 5G and open source. He shared several comments about DT’s strategy that we thought were interesting and showed that the German telco is looking to break away from old ways of doing business.
Activity surrounding Open RAN is hitting a fever pitch. We have been seeing accelerating operator and vendor announcements supporting Open RAN, and now the Open Networking Foundation has announced that it is launching SD-RAN to complement Open RAN. The plan for SD RAN is to open up critical portions of the RAN architecture, allowing both open source and vendor based microservices, called xApps, software connect to the SD RAN architecture’s Radio Ixxx Controller (RIC).
To date, we’ve seen vendors like Parallel Wireless, Mavenir, Altiostar, Samsung and Nokia throw their weight behind Open RAN. Japanese operator Rakuten has been very vocal about its successful commercial launch in April 2020 that uses Open RAN and a virtual computing system to support various RAN functions such as baseband. ONF’s SD RAN project takes things another step, though, by allowing operators and vendors to to leverage open source in the RAN environment.
Getting there presents a challenge. With its announcement, the ONF will support a nRT-RIC and xApps, this is the intelligence that needs to be opened up, according to Timon Sloane, VP for ecosystems and marketing for the ONF based in Menlo Park. He says that functionality from a powerful RIC and xApps can finally deliver the integration and benefits needed for an open approach to work.
Adding some muscle, the open RAN development community, and associated carriers globally, have shown their support for this latest project, a software defined RAN that will put a focus on open systems for 5G and the deeper integration.
The ONF’s SD-RAN project specifically is backed by a coterie of industry players: The O-RAN Alliance, Telecom Infrastructure Project (TIP), and Facebook. Also, global carriers and cloud providers like AT&T, Google, China Mobile, China Unicom, DT and NTT. Lastly, system/chip companies like Intel, Sercomm and Radisys.
The ONF’s proposed µONOS-RIC, is a microservices SDN controller based on ONF’s ONOS platform. 650 Group is bullish on this effort as previous attempts have not come to fruition and the ONF has already had lots of success with its CORD/cloud edge data centers and broadband access with the likes of AT&T DT and Comcast.
Today, HPE Aruba announced its Aruba Air Pass cloud service that allows for a hand-off between cellular and Wi-Fi networks. The service is enabled by Passpoint, which is a standard created by the Wi-Fi Alliance. The idea is that a mobile operator customer can go into a building with Wi-Fi coverage and, without having to "log on" to the Wi-Fi, the user's phone will automatically connect. Using Air Pass means that mobile operators won't need to build a cellular infrastructure in these buildings for customers to continue with their phone calls.
For mobile customers to see the benefit of seamless roaming from the Air Pass service, mobile operators will need to engage in a relationship with the property owners of the building. While this seems like a lot of work, connecting to Air Pass will be far easier than it would be for a property owner to install a cellular network inside the building. Examples of in-building cellular that can operate either on licensed, shared or unlicensed spectrum is a Distributed Antenna Systems (DAS) system or licensed small cells. Building owners or operators have to build new, in-building cellular if they want cellular coverage. Managed Service Providers, such as Federated Wireless, have begun selling a service to property owners where they will manage the cellular infrastructure for the owner.
Aruba has some competition for its service to allow Wi-Fi sharing to mobile operator customers. In February 2020, Cisco announced its Unified Domain Center as a means of sharing Wi-Fi coverage with mobile operators, as well, and claimed that it is at the proof of concept stage with operators. Also, Swedish software and services company, Aptilo, has created systems that allow SIM-based device users to roam onto Wi-Fi, as well. We applaud the efforts of Aruba, Cisco, Aptilo and many others who have built systems to allow device users to roam between cellular and Wi-Fi networks.
There has been a lot of excitement by mobile operators and cellular equipment suppliers about the 5G opportunity to expand to enterprises. In November 2019, for instance, Nokia discussed how enterprises are adopting its Private LTE systems to allow cellular coverage at customers such as utilities and shipping ports. We have been cautious on the idea that mobile operators will get lots of new revenue from providing cellular coverage to the enterprise; a year ago, we laid out our thoughts on the 5G Enterprise hype at the MWC19 show.
The implications of the emergence of services like Air Pass and the capabilities of Unified Domain Center is that Enterprise Wi-Fi coverage will be leveraged in the 5G era far more than all the hype about "5G" wiping out the need for Wi-Fi. However, we also feel that cellular systems will see growing popularity in certain enterprise verticals, as was evident at the MWC-Americas 2019 show.
Qualcomm made many wireless-related announcements today from its San Diego, CA headquarters, in place of making a presentation at #MWC20 in Barcelona. Top announcements included its FSM100xx 5G small cell chips customer announcements, RF-chip availability, Wi-Fi 6E demonstrations, and 5G smartphone customer announcements.
FSM100xx 5G RAN endorsements. Qualcomm announced its FSM 5G RAN platform in May 2018, targeting small cells and remote radio heads and enabling bothmmWave and sub-6 GHz spectrum using 10 nm process geometry. The company listed multiple vendors and operators in its press announcement relating to FMS100xx chips. Each of the vendors shared some interesting statistics, the most important of which we share here:
Qualcomm ultraSAW Filter. Expect availability in 2H20. Hit parity in performance in 2019 and now claims that its ultraSAW Filter will exceed performance of competitors, especially in high-bands.
Wi-Fi 6E. Qualcomm demonstrated 6 GHz operation between its Networking Pro Series (Wi-Fi 6 chips for Wi-Fi infrastructure like access points and routers). Qualcomm was not specific about the timetable for delivery of 6 GHz systems, but the company hinted that the 6 GHz demonstration “underscores Qualcomm’s readiness to extend its successful Wi-Fi 6 portfolio into the 6 GHz band for a transformative Wi-Fi 6E performance, pending regulatory approval.” The company expects that mobile devices using its Snapdragon 865 Mobile chips (intended for user devices like smartphones) can operate more than 3 Gbps when using the new 6 GHz spectrum, or 1.8 Gbps when using existing 2.4 GHz and 5 GHz available today. Qualcomm said its Networking Pro Series (Wi-Fi 6 chips) have been “deployed in more than 200 designs shipping or in development.”
Qualcomm Snapdragon 865 Mobile Platform. The company announced that its chip system for mobile phones that features its second-generation 5G Modem-RF system, the Snapdragon X55, has been “announced or are in development” in over 70 designs, including those from top vendors such as OPPO, Samsung, Xiaomi and ZTE.
Additionally, the company made VR devices and Personal Computer (PC) announcements including partners such as Facebook (VR) and Microsoft (PC).
Cisco’s many MWC announcements include a system to unify WiFi, LTE, CBRS, 5G called Unified Domain Center
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.
Summary of announcements by Cisco:
Unified Domain Center
IOT Control Center
SP Services Edge
Converged SDN Transport “New Engines”
Automated Network Operations
Trusted path routing
Last week, at Nokia's analyst meeting in Helsinki, it discussed its achievements and its challenges. The company’s successes include its traction and product introductions on the enterprise market, its market traction in selling Nokia’s end-to-end portfolio, and its 5G market momentum. Management reiterated that Nokia has signed 50 5G deals and its products are involved in 16 live 5G network. The company addresses some of its challenges, as well, including its delays in Systems on Chip (SoC) development progress, its diminished operating margins, competitive challenges in China, and an acknowledgement of increased price competition in the 5G era. We focus our writeup on two main topics: Enterprise and semiconductors.
Enterprise. The company leads with private LTE in selling to mostly outdoor environments where mobility needs are key. Nokia calls these networks “private wireless.” Generally, the target companies are those that are asset-intensive businesses, and Nokia has no current plans to go down-market. Nokia has sold to 120 enterprise customers as of September 2019, up from 80 as of June 2019.
Semiconductors. The company discussed semiconductors at great length at the meeting. Here is a summary of the main chips that were discussed.
Big themes at the show were WiFi-6, 6 GHz, and 802.11ah. We share some comments about the following organizations: WiFi Alliance, Commscope, Newracomm, Celeno, Cambium, Juniper Networks, On Semiconductor, Extreme Networks, Webb Search, Facebook, UK's Ofcom, Huawei, and 650 Group.
The WiFi Alliance and a handful of other speakers commented that WiFi-6 has lower latency than 5G, but the Alliance conceded that cellular had better mobility. We think the WiFi community is not doing enough to promote WiFi-6’s low latency capabilities
Commscope expects 6 GHz 802.11ax products to be shown at the CES show in January 2020 and that FEM and filters are not available today but will be by year-end or early 2020.
Newracomm is an 802.11ah (900 MHz WiFi) chip company that had won an award at the show. It claims to be an early leader in the market and based on comments made during presentations, we expect by 2H20, we will see systems and IoT services based on these types of chips.
Celeno, a stand-alone WiFi chip company, demonstrated radar on WiFi chip capability - the company won multiple award at the show. The company expects that a year from now, its Doppler on WiFi will emerge in products from SPs such as BT, Orange, and Comcast. The Doppler service only consumes about 3-5% of throughput capability when using Doppler and enables some very interesting capabilities such as fall detection, proximity detection, people counting and arm gestures.
ON Semiconductor's Quantenna group won an award at the show.
Cambium, in a presentation, explained that it is looking at an expansion to CBRS, 5G FWA backhaul, and 60 GHz.
Juniper Networks has been hiring in Europe as it expands its enterprise sales capabilities. It’s recently hired team made a positive impression on the audience. We tweeted about how great and fun the presentation by recent hire Jussi Nivikiemi’s presentation.
Extreme Networks presented its view that Artificial Intelligence won’t replace IT workers - it will just make them better.
A spectrum consultant - Webb Search - said that DFS is not working in the UK in 5 GHz and wastes a lot of bandwidth - most WiFi products don’t bother trying to operate one the spectrum covered by DFS. He advocated for using a database in the sky approach similar to what is being proposed for 6 GHz.
UK's Ofcom representative, Christina Data, explained that it is researching both 5 GHz and 6 GHz as a comprehensive solution. Ms. Data acknowledged that DFS may have some challenges and was diplomatic in response to questions about how 6 GHz will emerge.
Huawei advocated for an unpopular viewpoint (at a WiFi show) that 6 GHz device makers should register for IMT designation. In a panel that included German WiFi equipment vendor Lancom and Commscope, the other two vendors made counterpoints, including that this move to IMT will delay the rollout of 6 GHz by at least four years.
Facebook is advocating a non-AFC approach to low power 6 GHz in the US market. We have learned through multiple sources that it has recently a demonstrated a prototype of an AFC, however.
650 Group. The Chris DePuy presentation hit on three topics: unlicensed and shared spectrum impact on WiFi, WiFi and WiFi-6 shipments, and WiFi semiconductors.
We attended the operator and vendor consortium of 5G Americas. The themes of the show were: 5G, spectrum, cell siting, Asia-Pacific operator progress. For the second time in the past couple weeks, we saw FCC Commissioner Michael O'Reilly present, and his key messages were similar both times, focusing on CBRS, C-Band and 6 GHz. In attendance from the North American service provider side were AT&T, T-Mobile US, Shaw, and Sprint (we focused on NA operators mainly in this write-up). Notable vendors included Cisco, Commscope, Ericsson, Intel, Kathrein, Mavenir, Nokia, Qualcomm, and Samsung. We would say the most important theme from the show is the surge in interest in unlicensed spectrum, both for the use of mobile operators, as well as competing carriers, as well as by enterprises both for indoor and outdoor applications. For this write-up, we are focusing primarily on comments made by some of the leading operators who attended the conference.
AT&T discussed mmWave, future 3GPP releases, 5G phones, Mobile Edge Computing and indoor cellular, mid-band spectrum strategies, 5 GHz spectrum usage, Mobile Edge Computing (MEC), StandAlone (SA), among other topics. AT&T views mmWave as just a tool in the toolkit, so to speak, and not the only spectrum that is useful in 5G. It considers mmWave to be most helpful in urban and potentially indoor settings. Representatives said that future 5G-oriented Releases 16 & 17 are expected to be software upgrades to existing hardware and won't require new equipment to incorporate these new capabilities which will include network slicing. AT&T is making a big deal about its Mobile Edge Computing (MEC) initiative. At the conference, it emphasized MEC as having two main parts: a) expansion to about 100 edge sites (mostly Central Offices) from about 20 central locations in the LTE era and initially supporting packet core, and b) Microsoft Azure services managed end-to-end by AT&t. The company also emphasized that it plans to pursue some indoor cellular opportunities, some that currently leverage 5 GHz using LAA technology, some that will leverage CBRS and some that will leverage mmWave. We get the impression from AT&T that it is open in how it pursues future mid-band spectrum strategies. Its strategy could change based on: a) the timing of the CBRS PAL licenses (currently slated for June 25, 2020), b) the potential for C-Band private auctions (potentially in the mid 2020 timeframe), c) the potential for some or all of the 6 GHz spectrum availability (where Wi-Fi 6 would co-occupy), as well as other factors. We learned that, at least in certain regions, the company is making very ample use of 5 GHz spectrum using LAA techniques. AT&T seeing its picocells (small cells) get around 100 Mbps from LAA out of a total 130 Mbps inclusive of around three other licensed spectrums. We were surprised the company makes such ample use of unlicensed spectrum where Wi-Fi currently exists. The 5 GHz experience of AT&T leads us to think that 6 GHz, which promises to offer far more spectrum that the 5 GHz swath presently available, could be very beneficial to mobile operators and their consumers, as well as the Wi-Fi industry, and its consumers. AT&T expects that by this time next year, it will be "pushing" 5G to all its customers, part as a result of handsets adopting 5G capabilities, part the result of its network seeing nationwide coverage. Of the services that AT&T operates, it is installing mainly Packet Core in its MEC systems. AT&T is also planning to run Microsoft Azure services in its MEC locations. It expects that both Packet Core and Azure will see a 10-20 ms latency reduction by being located in MEC locations. AT&T says that StandAlone (SA) is "just new software," and downplayed the significance of the upgrade from EPC/NonStandAlone (NSA) to SA.
Sprint "is all-in on 2.5 GHz mid-band deployments for 5G services." Given the company's potential merger with T-Mobile USA, we view its network-build-out choices as being somewhat limited. It has limited options because it increases its near-term value to its acquirer, T-Mobile, if it deploys 5G in 2.5 GHz. Likewise, it is doesn't implement in mmWave, this reduces overlap with T-Mobile, who is deploying there. The company reiterated that it had launched 5G in 9 markets. It is seeing its peak speeds on 5G (aided by the fact that it has simultaneously upgraded hardware to Massive MIMO) be about 3-5 times that of its 8T8R LTE systems. It currently covers 11M POPs and 2,100 square miles with 5G. Sprint also shared that it sees RFPs from customers to replace Wi-Fi with 5G, though it didn't share more about this topic. The company's experience is that in upgrading its macro base stations to Massive MIMO 64T64R capabilities, it is getting 3-4x faster throughput than its 8T8R systems, though in the field these measurements vary widely. Additionally, Sprint said that its Massive MIMO systems relative to earlier systems show "generally the same coverage," with 1-2 dB better sometimes. Sprint is exploring ORAN and vRAN but "not adopting near term."
Shaw (Canada) presented its mobile LTE and 5G efforts and plans. Shaws plans are interesting because the company has significant cable services deployed in Canada. The company said nearly all the mobile technology it has installed in the past three years are "5G-ready." It will use 5G first in 600 MHz, then in mid-band (probably in 3.5 GHz) and the last in mmWave. Shaw expects that low-band 5G handsets will be available in 2020, and, similar to what AT&T said, it expects that is when 5G mobile will start in earnest in Canada. Shaw admitted that it is behind where the US operators are in deploying 5G, but offered no apologies, as it felt it is where it needs to be from a competitive standpoint in Canada. Almost laughing, Shaw explained that it would never consider deploying mmWave along highways, and that only high-density locations would get mmWave coverage. Shaw's view that mmWave is for high-density locations was shared universally by other operators in attendance, including AT&T, Sprint and T-Mobile US.
T-Mobile US spokespersons explained that mmWave has seen some challenges, relative to initial expectations and that while it does get mmWave to operate beyond near-line-of-sight, the view of T-Mobile is that mmWave is "just part of 5G." T-Mobile expects 3GPP Release 16 to be completed in 2020, but that it will be 2021 before it deploys Release 16, which won't require "a massive hardware refresh" and which will incorporate industrial and connected vehicles features. T-Mobile views 5G as being appropriate for indoor installations because while mmWave has challenges penetrating glass and concrete, but when 5G operates in low and mid-band spectrums, the "issue goes away." By 2020, T-Mobile expects StandAlone packet core to be ready, but since its current EPC/NonStandAlone (NSA) systems are already virtualized, the upgrade to SA is "not a forklift" upgrade. T-Mobile says virtual RAN (vRAN) "will take time," and that it will "need accelerators," which we take to mean FPGA-based Network Interface Cards (NICs) or the like to allow servers to operate faster than just x86 processors will allow.
