Key Takeaways
Market Background
Digitizing metering points, heat cost allocators, and water meters in the real estate sector presents fundamental challenges. Driven by regulatory mandates such as the European Energy Efficiency Directive (EED), consumption data must be collected at increasingly short intervals. Metering service providers, public utilities, and property managers require wireless standards that reliably reach meters installed deep in basements without blowing budgets on high recurring costs.
In practice, three dominant approaches compete in this space: the established short-range standard Wireless M-Bus (wM-Bus), the licensed cellular standard Narrowband IoT (NB-IoT), and the modern, license-free LPWAN technology mioty. Choosing the right transmission protocol significantly impacts the total cost of ownership (TCO) and long-term scalability of your project.
Technology Comparison
To select the best technology for your infrastructure, it helps to examine the underlying mechanisms of these three protocols:
Classic short-range radio (868 MHz / 433 MHz). Reliable over short distances, but requires multiple gateway cascades across stairwells in larger buildings. Learn more about wired M-Bus vs. wireless options.
Leverages existing mobile networks. Offers high coverage without local gateways, but incurs monthly SIM fees and higher energy consumption under poor reception conditions.
Splits data packets using Telegram Splitting. Penetrates thick concrete walls and connects thousands of endpoints with a single central gateway. Read details in our overview of mioty technology.
Modern systems integrate the Open Metering System standard. Explore OMS in Smart Buildings for vendor-independent submetering.
Infrastructure & Total Cost of Ownership
At first glance, the main advantage of NB-IoT is the absence of local gateway infrastructure, as meters transmit directly to cellular towers. In large-scale deployments with thousands of metering points, however, this approach generates significant ongoing operational costs (OPEX) through monthly SIM subscriptions and licensing fees. In contrast, mioty and wM-Bus operate in the license-free 868 MHz band. Once installed, data transmissions carry zero recurring network service charges.
Water meters and heat meters are frequently located deep in basement rooms or reinforced utility shafts. Wireless M-Bus rapidly reaches its limits here due to strong signal attenuation through walls. While NB-IoT utilizes Coverage Enhancement techniques, this significantly drains battery life under weak reception conditions. mioty solves this problem elegantly: through mathematical Telegram Splitting Multiple Access (TSMA), mioty achieves exceptional indoor penetration while maintaining ultra-low energy consumption.
In high-density residential complexes, hundreds of meters attempt to transmit simultaneously. In an uncoordinated wireless space, wM-Bus frequently suffers data loss due to packet overlaps. Conversely, mioty can read hundreds of thousands of meters per day via a single base station without suffering packet collisions.

| Criterion | Wireless M-Bus (wM-Bus) | NB-IoT | mioty |
|---|---|---|---|
| Frequency Spectrum | 868 MHz / 433 MHz (License-free) | Licensed Cellular Band | 868 MHz Band (License-free) |
| Recurring Costs (OPEX) | None (Private Network) | High (SIM Plan per Meter) | None (Private Network) |
| Range / Penetration | Low (Limited In-Building Reach) | Very Good (Subject to Carrier Coverage) | Excellent (Deep Basement Penetration) |
| Battery Lifespan | Good (10–12 Years) | Moderate to Good (Varies with Signal Strength) | Outstanding (Up to 20 Years) |
| Gateway Requirement | High (Many Repeaters Required) | No Local Gateways Required | Minimal (One Gateway for Entire Neighborhoods) |
The LUPUS Conclusion For isolated, widely scattered measurement points lacking local infrastructure, NB-IoT can be a viable option. However, when reading entire residential complexes, commercial parks, or multi-building estates, mioty outperforms both NB-IoT (in terms of operational expenses) and wM-Bus (in terms of range and reliability) by a wide margin.
