Evolving Telecom Network Infrastructure for IoT Apps

Wireless communication technology is a key component of most Internet of Things (IoT) projects. Choosing the best-fit solution can be challenging, due to the use of competing technologies. Mobile network service providers prefer open standards-based technology. So, that's a key market driver.

ABI Research forecasts that although proprietary Low-Power Wide-Area Networks (LPWANs) using LoRa, RPMA, and SIGFOX dominate today, the imminent commercialization of cellular LPWANs using the LTE Cat-M1, NB-IoT, and EC-GSM-IoT technologies will quickly rival the proprietary footprint.

Cellular LPWANs promise wide support from a large ecosystem, interoperability among vendors and mobile network operators, and the ability for existing cellular networks to rapidly scale up through a straightforward software upgrade with no new spectrum or hardware required.

Market Development of IoT Infrastructure

Telecom service providers throughout North America, Western Europe, and the Asia Pacific regions will lead the deployment of LPWANs for IoT.

"The window of opportunity for proprietary LPWA schemes to gain market share before the cellular juggernaut hits is drastically narrowing," said Nick Marshall, research director at ABI Research.

According to the ABI assessment, while LoRa, RPMA, and SIGFOX technologies account for almost three quarters of LPWANs today, there is significant traction in mobile network operator trials and planning for cellular LPWAN rollout.

Taking an 'LTE Cat-M1 first' approach, the U.S. region is on track to offer commercial networks as early as the forth quarter of 2016. Other regions will lead with an 'NB-IoT first' tactic, likely becoming available sometime in 2017.

Meanwhile, U.S. mobile network operators are adopting LTE Cat-M1 first since it's compliant with the widest array of IoT use cases, and these may demand higher data rates than NB-IoT can provide.

Network operators plan to subsequently update their networks to NB-IoT if required at a later date. In other regions, NB-IoT is preferred for its promise of lower cost end nodes and longer battery life.

Outlook for M2M Technology Deployements

Sunsets offer companies that rely on machine-to-machine (M2M) an opportunity to substitute licensed M2M technologies with proprietary LPWA technologies. To ensure continuity of their businesses, these companies may decide to use proprietary LPWANs immediately when faced with a network sunset and avoid the wait for commercial scale on cellular networks.

"World 2G and 3G cellular network connection sunsets are now accelerating, with double digit declines since 2015," concludes Marshall. "Although we can count on one hand the number of networks sunsetting in 2016, this number will multiply at least five times over by 2025."

Digital Transformation Spending Reaches $1.8 Trillion

Ongoing investment in business technology will remain on track, despite concerns about the global economic outlook which continues to evolve in 2022. Enterprise CIOs and CTOs are focused on operational profitability and digital business growth goals that are enabled by strategic IT initiatives. Global spending on the Digital Transformation (DX) of business practices, products, and organizations is forecast to reach $1.8 trillion in 2022 -- that's an increase of 17.6 percent over 2021, according to the latest market study by International Data Corporation (IDC). Many anticipated DX investments will sustain this pace of growth throughout the 2021-2025 forecast period, with a five-year compound annual growth rate (CAGR) of 16.6 percent. Digital Transformation Global Market Development "IDC expects to see aggressive DX technology investment growth in 2022 following a minor slowdown during the pandemic period," said Craig Simpson, senior research manager at IDC .

Why Cloud-Native is The Future of IT Spending

The leading organizations that create a digital transformation plan will gain the most from their use of public cloud computing. However, some CIO and CTO leaders still struggle with how to build a modern cloud migration strategy. The worldwide cloud computing Infrastructure as a Service (IaaS) market grew 41.4 percent in 2021, to a total of $90.9 billion -- that's up from $64.3 billion in 2020, according to the latest market study by Gartner. "The IaaS market continues to grow unabated as cloud-native becomes the primary architecture for modern workloads," said Sid Nag, vice president and analyst at Gartner . Cloud IaaS Market Development Cloud supports the scalability and composability that advanced technologies and applications require, while also enabling enterprise leaders to address emerging needs such as sovereignty, data integration, and enhanced customer experience. In 2021, the top five IaaS providers accounted for over 80 percent of the market. Amazon AWS conti

Private 5G Networks and Enterprise Wi-Fi Converge

The global enterprise wireless networking market is evolving. Driven by a desire to take advantage of the available 6 GHz communications spectrum, with greatly improved broadband throughput and latency rates, more organizations may choose to adopt Wi-Fi 6E technologies. According to the latest worldwide market study by ABI Research, shipments of Wi-Fi 6E access points and routers will rise from 1.5 million units in 2022 to 5.2 million units by 2024. Wireless spectrum expansion is just one facet of the commercial wireless network market transition, as the technology of Wi-Fi customer premise equipment will be upgraded once again with Wi-Fi 7 (IEEE 802.11be standard) devices. Enterprise Wireless Network Market Development "The adoption of Wi-Fi 7 access points will accelerate following the protocols standardization in 2024, and just two years later, most 6 GHz enabled access point shipments will be supporting Wi-Fi 7," said Andrew Spivey, industry analyst at ABI Research .
