  • The M2M, Iot & Wearable Technology Ecosystem
    +44 20 8123 2220 [email protected] The M2M, IoT & Wearable Technology Ecosystem: 2015 – 2030 – Opportunities, Challenges, Strategies, Industry Verticals and Forecasts https://marketpublishers.com/r/M9ED14DF916EN.html Date: November 2015 Pages: 1113 Price: US$ 3,500.00 (Single User License) ID: M9ED14DF916EN Abstracts As consumer voice and data service revenues reach their saturation point, mobile operators are keen to capitalize on other avenues to drive revenue growth. One such opportunity is providing network connectivity for M2M (Machine to Machine) devices like smart meters, connected cars and healthcare monitors. Despite its low ARPU, M2M connectivity has opened a multi-billion dollar revenue opportunity for mobile operators, MVNOs and service aggregators, addressing the application needs of several verticals markets. By enabling network connectivity among physical objects, M2M has also initiated the IoT (Internet of Things) vision - a global network of sensors, equipment, appliances, smart devices and applications that can communicate in real time. Another key opportunity is the monetization of wearable technology. Mobile device OEMs are aggressively investing in wearable devices, in order to offset declining margins in their traditional smartphone and tablet markets. As a result, the market has been flooded with a variety of smart bands, smart watches and other wearable devices capable of collecting, sending and processing data over mobile applications. Eyeing opportunities to route huge volumes of traffic from these wearable devices, many service providers are now seeking to fit wearable technology with their M2M offerings, targeting both consumer and vertical markets. SNS Research expects that M2M and wearable devices can help IoT service providers pocket as much as $231 Billion in service revenue by the end of 2020, following a CAGR of 40% between 2015 and 2020.

  • Initiating Coverage of Mergers and Acquisitions in Iot
    INITIATING COVERAGE OF MERGERS AND ACQUISITIONS IN IOT THE GOLD RUSH OF THE 21ST CENTURY BACKGROUND The IoT sector is beginning to feel like the frontier of the Wild West in the mid-nineteenth century. Yes, indeed, it was the Gold Rush where Americans, European hunters and trappers, and wealth seekers from around the world risked everything to chase their fortunes in California. Over approximately a five-year period, 250,000 miners found a total of $200 million in gold (worth tens of billions in today’s dollars). However, the vast majority of miners arriving late to the party ended up exhausted and broke. As panning gave way to more sophisticated and expensive mining technologies, so did the individual miner to large gold companies. At that stage, success on the frontier was defined by the ability to create and defend a community, improve productivity and use of the land, development of new markets, and ultimately, the conquest of competitors. Like the Gold Rush of the 1800s, IoT has started small and gathered momentum, changing company strategy, technology and social norms along the way. The question in front of every IoT entrepreneur and investor now is: Where will you fit into the spectrum of success in this new era, the “Gold Rush of the 21st Century?” Over the past couple of years, Mirus has become increasingly involved with the rapidly developing IoT sector from a variety of perspectives (see our most recent report on Mergers and Acquisitions in Manufacturing Automation and recent blog articles on the topic), including advising multiple companies across a variety of application domains on their growth and M&A strategy, as well as recently completing an important sell- side transaction in the space (see Eutecus press release).
