How LoRaWAN and AI Are Helping Erbil Prepare for Flash Floods

Flash flooding is a serious challenge for many cities, particularly where heavy rainfall can quickly overwhelm drainage systems and threaten populated areas. In Erbil, the capital of the Kurdistan Region of Iraq, a new AI-driven flood early warning system is demonstrating how Internet of Things (IoT) connectivity, environmental sensors and artificial intelligence can work together to improve disaster preparedness.

The system has been developed and deployed by local technology company TimeNet, using TEKTELIC KONA Macro LoRaWAN gateways to provide connectivity across Erbil and surrounding areas. The deployment uses eight strategically positioned gateways to connect a distributed network of environmental monitoring sensors, providing continuous information about changing weather conditions and potential flood risks.

The monitoring infrastructure collects information from several types of sensors, including river water level sensors, rain gauges, temperature sensors, lightning detectors, and wind speed and direction sensors. These measurements are transmitted over the LoRaWAN network to TimeNet's locally developed smart city platform, where the information is analysed to identify abnormal conditions and assess potential flood risks.

LoRaWAN (Long Range Wide Area Network) is particularly suitable for this type of application because it enables small amounts of sensor data to be transmitted over long distances while consuming relatively little power. This makes it useful for monitoring equipment installed in remote locations, drainage systems, riverbanks and other areas where installing wired communications infrastructure may be expensive or impractical.

The TEKTELIC KONA Macro gateways are designed for outdoor, carrier-grade deployments, with protection against harsh environmental conditions and radio-frequency interference. They also support remote management, which is particularly important for infrastructure that needs to remain operational during severe weather. Each gateway collects transmissions from nearby LoRaWAN sensors and forwards them towards the network and application infrastructure.

An important part of the Erbil deployment is the use of AI-driven analytics. Rather than simply displaying current sensor readings, TimeNet's platform combines live and historical environmental information to assess developing conditions, identify potential dangers and generate flood risk forecasts. This allows authorities to receive earlier indications of possible flooding and make more informed decisions about emergency preparations.

The system is also connected to a public-facing mobile application that provides flood risk notifications, danger-level updates and location-specific warnings. It is worth distinguishing the two communications functions here: LoRaWAN provides the connectivity for collecting environmental sensor data, while the mobile application provides information and alerts to authorities and citizens. The AI-based analysis sits between these two functions, converting sensor measurements into information that can support decisions and warnings.

Although the deployment demonstrates a promising use of IoT and AI, the published case study does not provide detailed information about the AI models, forecasting accuracy, warning lead times or the number of deployed sensors. These are important considerations when evaluating how effectively such a system can predict flooding and support public safety operations. Communications resilience, including gateway backhaul, power availability and the delivery of alerts during network disruptions, is another important consideration for operational flood-warning infrastructure.

Nevertheless, the project provides an interesting example of how relatively simple wireless sensors, wide-area IoT connectivity and locally developed AI applications can be combined to address real-world challenges. It also demonstrates that smart city connectivity does not always require high-bandwidth technologies such as 5G. For applications involving periodic environmental measurements, a low-power network such as LoRaWAN can be an effective part of the solution.

As cities increasingly face extreme weather events, deployments such as Erbil's flood early warning system show how connectivity and intelligent data analysis can contribute to making urban infrastructure more resilient.

Laser Inter-Satellite Links (LISLs) in a Starlink Constellation

When we first talked about Starlink back in 2019 , we saw in the video that the concept involved laser communication to communicate between the satellites. While the initially launched satellites did not have the laser communication mechanism built in, it looks like they are being added to the newer ones.  A report from Fast Company in late 2021 said: One of the next big upgrades in telecom will involve satellites firing lasers at each other—to beam data, not blow stuff up. The upside of replacing traditional radio-frequency communication with lasers, that encode data as pulses of light, can be much like that of deploying fiber-optic cable for terrestrial broadband: much faster speeds and much lower latency. “Laser links in orbit can reduce long-distance latency by as much as 50%, due to higher speed of light in vacuum & shorter path than undersea fiber,” SpaceX founder Elon Musk tweeted in July about the upgrade now beginning for that firm’s Starlink satellite constellation. ...

China’s Growing Constellations, Ambitions and the Future of Satellite Broadband

China is increasingly asserting its presence in the low Earth orbit (LEO) satellite broadband arena, with two major constellation programmes, one state-backed and one commercially driven, now under active deployment. The government’s strategic plan for global communications infrastructure includes the Guowang network, targeting as many as 13,000 satellites, and the municipally supported Qianfan, also known as “Thousand Sails,” which aims for around 15,000 satellites. As of November 2025, Guowang has exceeded 100 satellites in orbit following a launch of nine satellites on 10 November. The Qianfan project, by contrast, has deployed around 90 satellites to date, a fraction of its target for regional coverage by the end of 2025. Both networks face significant challenges including manufacturing scale-up, launch cadence, orbital debris and regulatory timelines, yet their evolution has direct implications for the future architecture of global broadband, the integration of satellite and terre...

IEEE 802.11bn Ultra High Reliability (UHR), a.k.a. Wi-Fi 8

Back in 2020 we looked at the introductory post of Wi-Fi 7 which was followed up by a more detailed post in Feb 2022. We are now following on with an introductory post on the next generation Wi-Fi.  A new paper on arXiv explores the journey towards IEEE 802.11bn Ultra High Reliability (UHR), the amendment that will form the basis of Wi-Fi 8. Quoting selected items from the paper  below: After providing an overview of the nearly completed Wi-Fi 7 standard, we present new use cases calling for further Wi-Fi evolution. We also outline current standardization, certification, and spectrum allocation activities, sharing updates from the newly formed UHR Study Group. We then introduce the disruptive new features envisioned for Wi-Fi 8 and discuss the associated research challenges. Among those, we focus on access point coordination and demonstrate that it could build upon 802.11be multi-link operation to make Ultra High Reliability a reality in Wi-Fi 8. The IEEE 802.11bn UHR: Whose ...
