Cellular IoT Wireless Network Technology Standards

One of the key principles that has enabled global wireless telecom network connectivity is the development and implementation of technology standards. As the Internet of Things (IoT) continues to evolve, new standards will set the stage for market development to blossom.

According to the latest worldwide market study by ABI Research, new 3GPP IoT standards will account for more than 50 percent of cellular IoT radio node unit shipments by 2021.

Moreover, Narrowband IoT (NB-IoT) is forecast to consume more than 70 percent of Release 13 shipments and more than one third of all cellular IoT shipments -- a value which is greater than legacy M2M or the current Cat-1 standard.

4G LTE Mobile Network Standards 

"While some in the industry view the new 3GPP standards as competitors to the current non-3GPP LPWA technologies and predict their demise, we believe that NB-IoT will complement LPWA," said Nick Marshall, research director at ABI Research.

However, ABI analysts believe that out of the 15 LPWA technologies that they profiled, some were designed for use cases that are unsuitable for NB-IoT -- such as where downlink data is not required.

The 3GPP Release recently finalized three, new cellular LTE-based IoT standards -- Cat-M1, NB-IoT, and EC-GSM -- that offer a cellular alternative to proprietary unlicensed Low-Power Wide-Area Network (LPWA) technologies like Ingenu, LoRa, and SIGFOX.

The standards make it easy to configure an LTE network through a simple software upgrade to the existing LTE radio interface, which is why ABI Research expects rapid growth and worldwide deployment of NB-IoT to start in 2017.

Ongoing IoT Technology Deployments

Pre-standard NB-IoT pilots and trials are already taking place, or are about to, with operators such as AT&T, China Mobile, China Unicom, Deutsche Telekom, Orange, Telefonica, and Vodafone working with equipment from vendors including Ericsson, Huawei, Intel, Nokia, and Qualcomm.

"Ultimately, the choice of IoT radio link involves trade-offs between conflicting features, which often involve capacity, licensed versus unlicensed operation, range, reliability, battery life, cost and proprietary versus standards-based schemes," concludes Marshall.

NB-IoT stands ready to unlock the full potential of IoT -- thanks to its high link budget for maximum coverage extension, low cost, and the ability to reuse existing LTE networks with carrier grade security.

Digital Transformation Investment at $3.4 Trillion

Business technology leadership matters. Across the globe, more leaders have been pursuing bold Digital Transformation (DX) initiatives with the goal of creating new sources of business value through digital products, services, and experiences. As an additional benefit, the COVID-19 pandemic revealed that digital transformation efforts improve an organization's resilience against global market disruptions. Global DX investment is forecast to reach $3.4 trillion in 2026 with a five-year compound annual growth rate (CAGR) of 16.3 percent, according to the latest worldwide market study by International Data Corporation (IDC). Digital Transformation Market Development "Despite strong headwinds from global supply chain constraints, soaring inflation, political uncertainty, and an impending recession, investment in digital transformation is expected to remain robust," said Craig Simpson, senior research manager at IDC .

Artificial Intelligence for National Border Security

National border protection agencies are under pressure to provide the highest level of security in the face of growing threats, such as increasing illegal migration and international terrorism. Now, government agencies are embracing advanced border security technologies to aid in effectively and reliably securing national borders. These solutions look to detect and identify potential threats and prevent them from escalating to a point that may jeopardize security. Security Surveillance Market Development Traditional border security patrols and Closed-circuit Television (CCTV) surveillance systems aren't adequate protection, and agencies must increasingly deploy new solutions to stay ahead of criminals and other potential threats to ensure the safety of a country’s borders. According to the latest market study by Juniper Research, the value of the border security technology market will exceed $70 billion globally in 2027 -- that's rising from $48 billion in 2022. Growing by 47 p

How to Apply Sustainability to Drive Value Creation

Global climate change policy initiatives have been an emerging topic for CEOs and their leadership teams, as they look to the future. Many organizations are preparing to play their part and help reduce carbon emissions. Eighty-seven percent of business leaders expect to increase their organization’s investment in sustainability over the next two years, according to the latest worldwide market study by Gartner. Customers are the stakeholder group creating pressure for these organizations to invest or act on sustainability issues -- selected by 80 percent of executives, followed by investors (60 percent) and regulators (55 percent). Sustainability Market Development "Sustainability enables businesses to cope with disruption," said Kristin Moyer, VP analyst at Gartner . "Economic uncertainty, geopolitical conflict and escalating materials and energy costs are forcing businesses to reexamine all forms of expenditure." According to Gartner, this focus on essentialism --
