    White Paper 5G for IoT? You’re Just in Time. A SIERRA WIRELESS WHITE PAPER With all the talk about 5G these days, it can be hard to decipher what is applicable for IoT applications, when it will be available and what the transition looks like for platforms currently on 2G, 3G or 4G technologies. The good news is that for companies in the IoT, true 5G is still on the horizon, making now the perfect time to start planning for its arrival. The 5th generation of cellular technology, commonly referred to as 5G, is slowly becoming a reality. What started in 2012 in the standards bodies has now evolved into a set of wireless technologies that are making the transition from standardization to commercialization. This paper looks at what that means for deployments in the Internet of Things (IoT). White Paper HOW ARE CELLULAR 5G is Coming in Waves STANDARDS DEFINED?

  • Iot Whitepaper
    IoT Solution Whitepaper WHITEPAPER, MARCH 2019 THE GAME CHANGER FOR THE INTERNET OF THINGS 1 IoT Solution Whitepaper INTRODUCTION The Internet of Things (IoT) is rapidly creating new ecosystems, revealing new insights and efficiencies, and enabling a vast array of new services and business models. While headline- grabbing IoT applications such as augmented reality or self-driving cars capture the imagination, many IoT use cases do not need to rely on high-performance wireless modules and low-latency, high-bandwidth connectivity. For Low Power Wide Area (LPWA) applications—such as smart metering, tracking of assets, and monitoring equipment—the key requirement is the ability to periodically exchange small amounts of data easily, reliably, and cost-effectively. Unlike most other existing mobile communications technologies, Narrowband IoT (NB-IoT) is optimized for these types of applications—making NB-IoT an ideal network technology for a broad array of IoT solutions. Billions of devices Low data volume Low energy consumption Deep indoor penetration Up to 100x more devices per cell Bidirectional, infrequent transmission Up to 10 years of battery-powered +20 dB link budget (compared (compared to GSM) of low data volumes.

  • 5G Wireless Infrastructure Semiconductor Analysis
    5G WIRELESS INFRASTRUCTURE SEMICONDUCTOR ANALYSIS SIA CONFIDENTIAL | 5G INFRASTRUCTURE ANALYSIS | 1 2 | 5G INFRASTRUCTURE ANALYSIS EXECUTIVE SUMMARY On behalf of SIA, a wireless market intelligence firm has analyzed all of the semiconductor function product families within the key elements of a 5G radio access network (RAN)- baseband unit (BBU) and active antenna unit (AAU)/remote radio unit (RRU) systems for 5G base stations along with the current domestic United States and foreign/international semiconductor suppliers. Our conclusion is that despite the United States maintaining overall market-share leadership in semiconductors with a 45% share of the global market, substitutes for U.S. components exist for nearly every semiconductor product family required to build a complete RAN infrastructure. In fact, our analysis indicates that of the more than fifty critical semiconductor elements necessary to design, manufacture, and sell a competitive 5G RAN network1, only 3 components could face supply constraints outside the United States in the event of an export restriction. For each of those three components, we have further concluded that alternatives are currently being deployed or under active development, especially within China by Huawei’s semiconductor design arm, HiSilicon. 8 | 5G INFRASTRUCTURE ANALYSIS | SIA CONFIDENTIAL OUR CONCLUSION FOR THE BASEBAND UNIT SYSTEM FOR A 5G BASE STATION IS THAT THE TWO KEY SEMICONDUCTOR PRODUCT FAMILIES THAT MAY PRESENT SUPPLY ISSUES OUTSIDE OF THE UNITED STATES ARE: • Commercial off-the-shelf Field

  • Overview of Risks Introduced by 5G Adoption in the United States
    CRITICAL INFRASTRUCTURE SECURITY AND RESILIENCE NOTE July 31, 2019; 1200 EDT OVERVIEW OF RISKS INTRODUCED BY 5G ADOPTION IN THE UNITED STATES KEY FINDINGS The Department of Homeland Security (DHS)/Cybersecurity and Infrastructure Security Agency (CISA) assesses that Fifth Generation Mobile Network (5G) will present opportunities and challenges, and its implementation will introduce vulnerabilities related to supply chains, deployment, network security, and the loss of competition and trusted options. Use of 5G components manufactured by untrusted companies could expose U.S. entities to risks introduced by malicious software and hardware, counterfeit components, and component flaws caused by poor manufacturing processes and maintenance procedures. 5G hardware, software, and services provided by untrusted entities could increase the risk of compromise to the confidentiality, integrity, and availability of network assets. Even if U.S. networks are secure, U.S. data that travels overseas through untrusted telecommunication networksi is potentially at risk of interception, manipulation, disruption, and destruction. 5G will use more components than previous generations of wireless networks, and the proliferation of 5G infrastructure may provide malicious actors more attack vectors. The effectiveness of 5G’s security enhancements will in part depend on proper implementation and configuration. Despite security enhancement over previous generations, it is unknown what new vulnerabilities may be discovered in 5G networks. Further, 5G builds upon previous generations of wireless networks and will initially be integrated into 4G Long-Term Evolution (LTE) networks that contain some legacy vulnerabilities. Untrusted companies may be less likely to participate in interoperability efforts. Custom 5G technologies that do not meet interoperability standards may be difficult to update, repair, and replace.
