References 2 IoT Cellular Networks 1. In Brief 01. In brief 1. IoT connectivity opens doors to new markets, but also allows for easy entry of new competitors through proprietary technologies in the unlicensed bands. 2. To provide LPWAN (Low Power Wide Area Network) connectivity operators may choose proprietary technologies, such as Sigfox or LoRa, 3GPP standardized systems such as EC-GSM, LTE- M or NB-IoT, or a mix of both. 3. LPWAN proprietary technologies have been in the field for some time, while standard solutions are already available but still starting. 4. The unlicensed spectrum used by proprietary technologies could represent a difficulty in terms of reliability and service level assurance due to the high number of competing technologies sharing the same spectrum, while licensed spectrum used by 3GPP standardized systems allows for the control of quality of service. 5. Proprietary solutions have lower prices and achieve higher levels of penetration with simpler deployments, while 3GPP cellular technologies offer the quality of mobile networks, enable higher throughputs and take advantage of existing operational and business systems. 4 IoT Cellular Networks 01. In brief 6. The prices of the communication modules continue to decrease, but are still far from the target prices, with Sigfox presenting hard-to-beat prices (around $1 per module vs $12 per NB-IoT module in 2018). (1) 7. Partnering with LPWAN vendors, such as Sigfox, fosters a fast entry into the market, but may limit the definition of the operator's strategy as it becomes dependent on third-party decisions.

  • Long-Range Wireless Radio Technologies: a Survey
    future internet Review Long-Range Wireless Radio Technologies: A Survey Brandon Foubert * and Nathalie Mitton Inria Lille - Nord Europe, 59650 Villeneuve d’Ascq, France; [email protected] * Correspondence: [email protected] Received: 19 December 2019; Accepted: 11 January 2020; Published: 14 January 2020 Abstract: Wireless networks are now a part of the everyday life of many people and are used for many applications. Recently, new technologies that enable low-power and long-range communications have emerged. These technologies, in opposition to more traditional communication technologies rather defined as "short range", allow kilometer-wide wireless communications. Long-range technologies are used to form Low-Power Wide-Area Networks (LPWAN). Many LPWAN technologies are available, and they offer different performances, business models etc., answering different applications’ needs. This makes it hard to find the right tool for a specific use case. In this article, we present a survey about the long-range technologies available presently as well as the technical characteristics they offer. Then we propose a discussion about the energy consumption of each alternative and which one may be most adapted depending on the use case requirements and expectations, as well as guidelines to choose the best suited technology. Keywords: long-range; wireless; IoT; LPWAN; mobile; cellular; LoRa; Sigfox; LTE-M; NB-IoT 1. Introduction Wireless radio technologies, such as Wi-Fi, are used daily to enable inter-device communications. In the last few years, new kinds of wireless technologies have emerged. In opposition to standard wireless technologies referred to as “short-range”, long-range radio technologies allow devices to communicate over kilometers-wide distances at a low energy cost, but at the expense of a low data rate.

Chaudhari *,1, Marco Zennaro 2 and Suresh Borkar 3 1 School of Electronics and Communication Engineering, MIT World Peace University, Pune 411038, India 2 Telecommunications/ICT4D Laboratory, The Abdus Salam International Centre for Theoretical Physics, Strada Costiera, 11-I-34151 Trieste, Italy; [email protected] 3 Department of Electrical and Computer Engineering, Illinois Institute of Technology, Chicago, IL 60616, USA; [email protected] * Correspondence: [email protected] Received: 7 January 2020; Accepted: 4 March 2020; Published: 6 March 2020 Abstract: Low power wide area network (LPWAN) is a promising solution for long range and low power Internet of Things (IoT) and machine to machine (M2M) communication applications. This paper focuses on defining a systematic and powerful approach of identifying the key characteristics of such applications, translating them into explicit requirements, and then deriving the associated design considerations. LPWANs are resource-constrained networks and are primarily characterized by long battery life operation, extended coverage, high capacity, and low device and deployment costs. These characteristics translate into a key set of requirements including M2M traffic management, massive capacity, energy efficiency, low power operations, extended coverage, security, and interworking. The set of corresponding design considerations is identified in terms of two categories, desired or expected ones and enhanced ones, which reflect the wide range of characteristics associated with LPWAN-based applications. Prominent design constructs include admission and user traffic management, interference management, energy saving modes of operation, lightweight media access control (MAC) protocols, accurate location identification, security coverage techniques, and flexible software re-configurability.

  • Wireless RF: the Ins and Outs of LPWAN Technologies
    Wireless RF: The Ins and Outs of LPWAN Technologies Semtech October 2020 Wireless RF: The Ins and Outs of LPWAN Technologies semtech.com/LoRa Page 1 of 21 Technical Paper Proprietary October 2020 Semtech In this article we discuss radio frequency (RF) fundamentals and build upon these concepts to help the technical architects responsible for designing Internet of Things (IoT) solutions understand the impact of RF on low power wide area networks (LPWANs). The goal of this article is to help technical architects choose from among the different LPWAN options to best meet the needs of their LPWAN solutions. In the first section, RF fundamentals, we cover the basics of radio frequency and explain how the frequency chosen has a direct relationship with the amount of data that can be transmitted, the range the signal can reach and the power requirements of the device. If you are comfortable with radio frequency basics, skip to the section on RF-based Networks for IoT. Next, we’ll touch on wireless personal area network (WPAN) solutions like Wi-Fi, Bluetooth, Zigbee and Z-Wave, and explain why these are not suitable when building a network that needs to run over a wide area, as these all have a relatively short range. Finally, we will review some of the most commonly-used LPWAN options with a focus on cellular technologies (NB-IoT and LTE-M), and those using unlicensed bandwidth, LoRa®/LoRaWAN® and Sigfox. We’ll also explore the differences among these technologies to help you select the right option for your use case.

  • Ienbl: the Ultimate Low Power, Wide Area Network, Rapid
    White Paper iENBL: The Introduction To date, the machine-to-machine communication (M2M) business has Ultimate Low been dominated by the owners of the wide area cellular networks (WAN), namely, the mobile network operators grouped under the Power, Wide Area GSMA and 3GPP associations. Only customers of these operators had wide area connectivity to their devices. The new wireless technologies Network, Rapid operating in unlicensed Industrial, Scientific and Medical (ISM) bands are designed to provide low data rates, long-distance reach, deep Development building penetration, low energy consumption and low cost for connectivity services and end devices. During the past two years, Platform these technologies have significantly changed the WAN connectivity landscape of Internet of Things (IoT) devices. A Development Kit for In the near future, a myriad of simple and ultra-low-power devices will permeate all aspects of our daily lives. They will be part of our homes, Rapid IoT Application the buildings we visit, our modes of transportation, our apparel and Prototyping and Field more. Those devices will interpret our world by collecting data that will be used to provide valuable, actionable insights to help inform Testing our decisions. Low Power Wide Area Networks (LPWAN) like LoRa and Sigfox, which are the two most widely deployed, are changing the “smartphone IoT hub” paradigm that allows IoT devices to connect to the Internet only when a smartphone is nearby. LPWAN enables us to sense our world by transforming everyday objects into smart objects, cities into smart cities, and workplaces into smart work environments. Unlicensed, open and no-cost frequencies are good for consumers, but not for mobile carriers that have spent billions of dollars acquiring the exclusive use of licensed frequencies.
