Last week, LoRa chip company, Semtech, made several announcements that should accelerate the IoT market. First, it announced LoRa Basics Modem-E, which is a software modem. Second, it announced relationships with IoT companies, Actility and Tago.IO that surround services that can be offered to drive the IoT market. Third, the company announced the LoRa Edge Tracker Reference design, which is a "device to cloud" reference design for asset tracking applications. In our IoT research, we have forecasted a near-doubling each year over the next five years for LoRa and competing devices. We believe Semtech's recent announcements as driving the market because they make it easier, cheaper and faster to deploy IoT services.
The LoRa Basics Modem-E allows customers to use modem capabilities from Semtech, where previously the customer would have had to have developed this technology itself or commissioned a third-party software design house to develop it for them. We see it as a slight increase in the "footprint," or addressable market in each IoT device that benefits Semtech. However, Semtech's Director of LoRa Product Line Management in Semtech's Wireless and Sensing Product Group, Sree Durbha, explains, using the Modem-E can reduce the total cost of ownership of an IoT application by as much as 47% over three years for a deployment of ten thousand devices or more. The savings come from both up-front savings and ongoing savings. Upfront savings are from being able to use a smaller microcontroller unit (MCU) with a smaller footprint, reduced non-recurring engineering (NRE) spending to develop the modem, and reduced certification costs enabled by the LoRa Basics Modem-E. The ongoing savings come from maintenance and testins costs for future modem releases, which Semtech will make available to its customers and partners on a regular basis.
We spent some time discussing the cloud service with Mr. Durbha, as well, and learned that Semtech's LoRa Cloud service can enable geolocation and LoRa device and application services like GNSS almanac updates. We tried to get a general sense for the prices involved on a per device basis and learned that for the asset tracking application, each device can be tracked for under $1/year. There are many variables that come into play like usage rates, for instance, that can change this number.
All told, we think that by offering reference designs, tight relationships with service providers, developing more of the footprint of an IoT system, and reducing costs to customers, Semtech is working to accelerate the IoT market - and of course, its participation with LoRa technology.
We attended the Mobile World Congress last week in Barcelona along with an estimated 104,00 others from nearly every country in the world. We met with over 42 companies and nearly 200 people at the show and attended many press announcements. While most of the MWC19 headlines were about 5G, we were struck that much of the hyped growth will in fact be the result of deployments in enterprises and could be served using unlicensed (or lightly licensed) spectrum. Many of the presentations and product announcements suggested as much, if you read between the lines. We'll step through these two, enterprise and unlicensed next.
The Enterprise opportunity. A major theme we picked up at the Mobile World Congress show is simple: that for the mobile telecom market to grow, 5G must expand to the enterprise. We see ample evidence that without an expansion to the enterprise, the cellular market as we know it will likely experience declines as consumers expect more bandwidth for less in the future. The 5G narrative at the MWC19 show was straightforward: German & Chinese robots, trucks and drones need 5G to unlock the potential for future growth. There were robots, drones and trucks bleeping and whirring to make the point for visitors. We wouldn't argue with the contention that robots and very fast moving vehicles that are controlled remotely need very low latency; yet, there are so many use cases that don't actually need such low latencies.
Wireless is just a small part of "Enterprise." Enterprise 5G use cases being presented at MWC, including the wirelessly controlled robot, involved far more than just a wireless connection to succeed. To automate a workplace with robots, there is far more technology that has to be brought to market, including software, integration, wireline networking and the list goes on. None of these capabilities have traditionally been delivered by telecom equipment vendors; they have been delivered by vendors who have served the enterprise market (examples would be Cisco, IBM, Oracle, etc.).
Unlicensed Opportunity is Robust. In both the enterprise market and the outdoor market, unlicensed spectrum has tremendous potential. This goes for a) WiFi, which is already immensely popular, b) for in-building 'lightly licensed' CBRS (a US-only market), c) the soon-to-be released 6 Ghz spectrum, as well as d) outdoor mid-band spectrum like 5 Ghz (already very popular), e) outdoor 60 Ghz (like the kind relating to the Facebook Terragraph project) and f) 900 Mhz LoRa. While each of these unlicensed (or lightly licensed) frequencies was discussed at the show, 5G licensed was so overwhelmingly promoted it was hard for these exciting unlicensed markets to get any airtime. We think this lack coverage relatively speaking is a dis-service and we'll touch on just a few of them in this post.
Wi-Fi isn't going away. Related to the enterprise 5G topic, we found points and counterpoints about 5G versus WiFi interesting. Huawei's Enterprise group issued a press release about its 802.11ax (WiFi-6) expectations and how important WiFi is for the enterprise market. On the other hand, Huawei's telecom group was pursuing a press agenda about partnering with Operators to pursue the 5G market. Few companies on earth possess as broad a produt portfolio as Huawei, who has ample expertise, market share and credibility in both the mobile wireless market and the enterprise wireless market. We felt this dual-message (5g AND WiFi) was well-balanced. On the other hand, vendors and operators who have historically focused on cellular-only were pushing a "5G will displace WiFi" or at least a "5G is the only solution for mission critical enterprise" agenda. We feel that 5G-only in the enterprise message is to broad-based; we think 5G in the enterprise is far more nuanced because:
802.11ax/WiFi-6 is cellular-like. 802.11ax, which was launched commercially in 4Q18, incorporates many cellular-like capabilities. Many of the technical merits debates presented at MWC compared older 802.11ac WiFi against LTE and 5G NR. This is not a fair comparison because both 5G NR and 802.11ax actually began shipping commercially generally at the same time (4Q18 and 1Q19).
There is very little overlap between the Wi-Fi opportunity and that for cellular. The overlap in opportunities being discussed as the 5G enterprise opportunity at MWC have surprisingly little overlap with the vertical industries currently being served by Enterprise-class WiFi. Take manufacturing, which represents 9% of the Enterprise WLAN market by units in 4Q18. Or the outdoor WLAN market, which is only 3% of total Enterprise-class market in 4Q18 by shipments. The point is, there is very little overlap between the Enterprise WLAN market and the 5G enterprise market being discussed at MWC.
LTE will be the workhorse for many years. Additionally, let's consider the fact that many of the use-cases being discussed at MWC will initially be served by LTE, not 5G. In the enterprise market, the use of LTE in unlicensed (or lightly licensed, like the US's CBRS) bands is often called private LTE. The main difference between unlicensed LTE and licensed LTE is that with unlicensed, the enterprise can work directly with enterprise-focused VARs, resllers, solutions providers and complementary equipment suppliers, while with licensed LTE, the enterprise will need to work directly with its local mobile service provider who owns the spectrum, likely ensuring that the operators becomes the prime integrator of the project, or at least part of it. Private LTE will therefore have fewer parties involved (no operator), lower monthly costs (no operator) and will likely get the project to completion faster (fewer parties and a prime vendor/contractor/solutions-provider with expertise in the enterprise's vertical market). So, why not consider unlicensed/lightly-licensed LTE instead of licensed 5G to achieve the goals illustrated in many of the 5G use cases at MWC?
Where will WiFi lose out? If it has wheels or wings on it, Wi-Fi is not your friend - look to cellular.
To conclude, yes, 5G will fit some very exciting use-cases, especially those for low-latency applications. These are indeed exciting and deserve attention. We see it this way for the wireless industry: if the things involved have wheels or wings, or are of such high value that you must use cellular, there's a good chance LTE will cut it. And next, it makes sense to consider using unlicensed spectrum - which is just emerging as viable for many uses.
Arris held its annual investor day late last week on March 28, 2018. It was interesting: the company said "Everything is going wireless," which is an interesting admission for a company that, until about a year ago, was essentially a pureplay on wired broadband. To be sure, the company has diversified into wireless with its acquisition of Ruckus and has benefitted from the inclusion of Wi-Fi capabilities to its broadband CPE. The company sees this wireless future - and is pivoting towards it.
Arris management highlighted that it expect its future to include the following growth avenues:
Additionally, the company discussed its expectations for each division, which using its 2017 mix and various projections, calculates to a 4.7% CAGR from '17 to '21.
Enterprise Networking (Ruckus). Overall, the company's Enterprise Networking division, also known as Ruckus Networking, includes its Enterprise WLAN business (formerly Ruckus Wireless), the Brocade ICX Ethernet Switch product line (referred to by the company as Campus Switching), and other revenue streams such as CBRS 3.5 Ghz LTE Small Cells, as well as IoT radio modules that plug into the Ruckus Access Points like Bluetooth, LoRa and Zigbee. The company is targeting 20%+ growth for the Ruckus Networking group, which is far above the industry growth rates we expect for Enterprise plus Outdoor WLAN and Campus switching. This aggressive growth rate either implies share-taking, or growth in other products such as CBRS, Bluetooth, LoRa and Zigbee, or the the non-WLAN parts of what used to be Ruckus Wireless, such as Cloud-managed Wireless LAN services (that, for instance compete with Cisco's Meraki, Aerohive services and Mojo Networks). The company cited an expected Enterprise WLAN revenue growth projection slightly above our projection for the period '17 to '21, even if cloud-managed WiFi services were included.
Network and Cloud Segment. The company said this market is growing 5% annually, and described the market generally as the Cable Modem Infrastructure, optical nodes and cable video networks market. The company generally expects to take share, compared to this market viewpoint, projecting a 4-7% long-term annual growth expectation for this business segment. It was interesting that the company said that the "mobile device explosion [is] driving offload demand," because it has been several years since "Wi-Fi offload" was a growth driver, but dissecting the comment a bit more, the company is pointing to cable operators as being "well positioned to handle [the] offload." We think Arris' strong supplier position with the major Cable MSOs in the US, especially, may indicate that there should be a strong build up of WiFi and cable infrastructure coming in the future. And, this corroborates with our own research and statements from MSOs such as Comcast. In fact, the company showed a "future" network diagram that indicates it expects its MSO customers will be delivering 5G radio, Remote OLTs (PON) and Fixed Wireless Access instead the of cable modem (DOCSIS) equipment that was indicated in the "now" chart. This implied shift from DOCSIS to PON/5G/FWA would be a dramatic shift in the company's product portfolio. Very interesting, indeed.
Customer Premises Equipment (CPE) Segment. The company claims a #1 Set Top Box (STB) market share, and #2 Broadband CPE market share, with a mix of 60% video CPE and 40% broadband revenues in 2017. The company expects to grow broadband CPE to a mix of 50%+ by the year 2021, consistent with the market growth rates it cites - 4% CAGR for broadband and -.8% for video. Generally, the company is projecting long term sales trend of -5% to +1%, indicating that it lacks the direct to market exposure that would get it to a growth expectation in this segment. The company confirmed it is using NBASE-T (Multi-Gigabit Ethernet) interfaces on its home networking devices and it is planning to release 802.11ax capabilities on its portfolio, as well. Arris CPE will also include Extenders / Adapters to, at least partially, address the growth now occurring in the Consumer Mesh market.
