Bad news, mobile operators: Unlicensed IoT tech rocketing ahead of NB-IoT and LTE-M – report

Plus global mobe mobs name Sigfox top IoT tech lag


Internet of Things connectivity tech firm Sigfox is the market daddy, having left competing mobile operator-backed techs for dust – so sayeth ABI Research.

In a briefing distributed to world+dog this morning, the consultancy said: "In 2017, SIGFOX had the largest share of public LPWA [Low Powered Wide Area] connections worldwide benefiting from its first mover advantage in Europe."

The research outfit also noted that "private LPWA networks", those built by IoT customers without the involvement of mobile networks, "accounted for 93 per cent of connections in 2017".

This is not good news for mobile network operators, which are mostly pinning their IoT connectivity hopes on the NB-IoT and LTE-M connectivity specs. Both of these operate in licensed spectrum, whereas private networks using standards such as Sigfox and its LoRaWAN competitor use unlicensed spectrum, relying on the low probability of interference to maintain quality of service.

LoRa itself saw 54 per cent year-on-year growth, according to ABI's findings. Though the consultancy did not break out absolute numbers, it attributed this increase in popularity to China, where it reckoned 40 Chinese cities had deployed LoRa for uses such as smart meters, parking sensors, air quality sensors and the like. Those desperate to know more will have to register to buy the full report.

The consultancy also said smart meters would experience a 53 per cent compound annual growth rate between now and 2023. Such a prediction about the growth of IoT tech, while in line with others, may or may not come to pass as mobile network operators continue to promise big and deliver little with NB-IoT and LTE-M, even with the promise of 5G's native support for IoT connectivity. ®

  • AMD refreshes Ryzen Embedded line with R2000 series
    The target? Thin clients and industrial devices – with new SoC family running up to 4 independent displays

    Embedded World AMD is bringing to market a new generation of Ryzen chips for embedded apps promising more CPU cores, enhanced built-in graphics and expanded I/O connectivity to drive kit such as IoT devices and thin clients.

    Crucially, AMD plans to make the R2000 Series available for up to 10 years, providing OEM customers with a long-lifecycle support roadmap. This is an important aspect for components in embedded systems, which may be operating in situ for longer periods than the typical three to five-year lifecycle of corporate laptops and servers.

    The Ryzen Embedded R2000 Series is AMD's second-generation of mid-range system-on-chip (SoC) processors that combine CPU cores plus Radeon graphics, and target a range of embedded systems such as industrial and robotic hardware, machine vision, IoT and thin client devices. The first, R1000, came out in 2019.

  • What if ransomware evolved to hit IoT in the enterprise?
    Proof-of-concept lab work demos potential future threat

    Forescout researchers have demonstrated how ransomware could spread through an enterprise from vulnerable Internet-of-Things gear.

    The security firm's Vedere Labs team said it developed a proof-of-concept strain of this type of next-generation malware, which they called R4IoT. After gaining initial access via IoT devices, the malware moves laterally through the IT network, deploying ransomware and cryptocurrency miners while also exfiltrating data, before taking advantage of operational technology (OT) systems to potentially physically disrupt critical business operations, such as pipelines or manufacturing equipment.

    In other words: a complete albeit theoretical corporate nightmare.

  • DeadBolt ransomware takes another shot at QNAP storage
    Keep boxes updated and protected to avoid a NAS-ty shock

    QNAP is warning users about another wave of DeadBolt ransomware attacks against its network-attached storage (NAS) devices – and urged customers to update their devices' QTS or QuTS hero operating systems to the latest versions.

    The latest outbreak – detailed in a Friday advisory – is at least the fourth campaign by the DeadBolt gang against the vendor's users this year. According to QNAP officials, this particular run is encrypting files on NAS devices running outdated versions of Linux-based QTS 4.x, which presumably have some sort of exploitable weakness.

    The previous attacks occurred in January, March, and May.
