How Netze BW Deployed Fleximodo LoRa Mini Sensors on Germany's Largest LoRaWAN Network

Deployment Snapshot

The Client

Netze BW GmbH is Baden-Württemberg's largest distribution network operator and a wholly owned subsidiary of the EnBW Group — one of Germany's four major energy companies. The company operates approximately 95,000 kilometres of electricity, gas, water, and fibre optic infrastructure serving 3 million households and businesses, making it Germany's third-largest grid operator.

Crucially for this deployment, Netze BW operates Germany's largest LoRaWAN network: 3,000 gateways spanning its entire service region, supporting smart metering, water monitoring, and municipal IoT applications. The LoRaWAN infrastructure is managed from EnBW's own data centres, ensuring data sovereignty — a critical requirement for German utility operators.

The Challenge: Adding Smart Parking to an Existing LoRaWAN Ecosystem

With 3,000 LoRaWAN gateways already deployed across Baden-Württemberg, Netze BW has the connectivity infrastructure but needs a compatible LoRaWAN parking sensor. The company's municipal clients — cities and utilities across the region — are requesting smart parking as an extension of the IoT services already running on Netze BW's network. The challenge is not infrastructure build-out (which already exists) but finding a production-ready smart parking sensor that integrates seamlessly with the existing LoRaWAN network, supports the utility's operating model, and delivers the accuracy municipal clients expect.

The Solution: OPEX-Free Mini Sensors on Existing Infrastructure

Netze BW's June 2023 order deployed Fleximodo LoRa Parking Sensor Mini units under an OPEX-free pricing model — a significant choice that reveals how the utility plans to position parking within its service portfolio.

The deployment included:

• LoRa Parking Sensor Mini — Surface-mount sensors connecting to Netze BW's existing 3,000-gateway LoRaWAN network with no additional infrastructure required
• OPEX-free pricing model — No annual subscription fees. Backend connectivity included for the hardware's lifetime. Support available at €95/hour (minimum 30 minutes) on a pay-per-incident basis.

The OPEX-free model is strategically important for a utility operator. By paying upfront for hardware and lifetime connectivity with no recurring Fleximodo fees, Netze BW can set its own pricing to municipal clients — bundling parking sensor data alongside smart metering and water monitoring within its existing LoRaWAN-as-a-Service offering. The Mini sensor format (surface-mount, no drilling) enables rapid deployment across multiple municipal sites without road works coordination — critical when deploying across dozens of towns in a utility service area.

Fleximodo IoT Parking Sensor Mini: Technical Profile

The Mini sensor's LoRaWAN connectivity and surface-mount installation make it the natural choice for a network operator looking to scale a LoRaWAN parking sensor deployment across its existing gateway infrastructure.

Specification	Detail
Detection method	3-axis magnetic field + nanoradar (dual-sensing)
Detection accuracy	99.7%
Dimensions	95 × 95 × 65 mm
Weight	230 g
Battery	3.6 V, 13 Ah (6-year operational lifetime)
Connectivity	LoRaWAN Class A/B/C
Installation	Surface-mount (no drilling required)
Ingress protection	IP67
Operating temperature	-40 to +85 °C

Because the Mini's magnetometer-based detection method is inherently sensitive to temperature-driven drift in its magnetic reference point, Fleximodo builds automatic temperature compensation into the sensor firmware. This keeps the 99.7% accuracy figure stable across the full -40 to +85 °C range, so a Baden-Württemberg winter freeze or summer heatwave doesn't introduce false occupancy readings on Netze BW's network.

Why This Deployment Works

Netze BW's existing LoRaWAN infrastructure eliminates the single largest barrier to smart parking deployment: connectivity. With 3,000 gateways already covering Baden-Württemberg, every Fleximodo sensor placed in the region immediately has network access. The OPEX-free model removes the second barrier — recurring costs — allowing Netze BW to amortise sensor costs over the hardware lifetime while generating its own recurring revenue from municipal IoT service agreements. This is how a utility company turns a parking sensor into a line item on an existing managed services invoice.

Frequently Asked Questions

What is Netze BW? Netze BW GmbH is Baden-Württemberg's largest distribution network operator and a subsidiary of EnBW, one of Germany's four major energy companies. The company operates 95,000 kilometres of electricity, gas, water, and fibre optic networks serving 3 million households. Netze BW also runs Germany's largest LoRaWAN network with 3,000 gateways — supporting smart metering, water monitoring, and municipal IoT services from EnBW's own data centres.

What is the OPEX-free pricing model for Fleximodo sensors? Under the OPEX-free model, clients pay upfront for sensor hardware with backend connectivity included for the hardware's lifetime — no annual subscription fees. Technical support is available on a pay-per-incident basis (€95/hour, minimum 30 minutes). This model suits operators like utilities and telecoms who prefer capital expenditure over recurring costs and want to control their own pricing to end customers.

How many LoRaWAN gateways does Netze BW operate? Netze BW operates 3,000 LoRaWAN gateways across its entire Baden-Württemberg service region — making it Germany's largest LoRaWAN network. This infrastructure, managed from EnBW's own data centres, supports multiple IoT applications including smart metering, water monitoring, environmental sensing, and now smart parking, all on a single connectivity platform.

What is automatic temperature compensation in a magnetometer parking sensor? Automatic temperature compensation continuously corrects the magnetic reference baseline that a magnetometer parking sensor uses to detect vehicles, offsetting the drift that heat and cold otherwise introduce. Without it, seasonal temperature swings could cause false occupied or vacant readings. Fleximodo's LoRaWAN parking sensors use automatic temperature compensation to hold consistent accuracy across a -40 to +85 °C operating range.
