LPWAN stands for Low Power Wide Area Network. In simple terms, its connectivity designed for IoT devices that:
Cellular LPWAN uses existing mobile networks, so there’s no need to build or manage your own infrastructure.
In the UK, there are two main cellular LPWAN technologies in use today: NB-IoT and LTE-M.
LTE-M vs NB-IoT in simple terms
Both technologies are designed for low-power IoT devices that send small amounts of data and need to operate reliably for years.
If you’re connecting sensors that send small amounts of data and need long battery life, LTE-M and NB-IoT are the two cellularLPWAN options designed specifically for the job.
Choose LTE-M when you need:
Choose NB-IoT when you need:
Quick rule of thumb:
If the device moves or needs more interaction, lean LTE-M.
If the device is static and sends tiny updates, lean NB-IoT.
At Lister, we help UK organisations select the right technology and deliver it as a dependable, supported service.
This table focuses specifically on cellular LPWAN technologies — LTE-M and NB-IoT — which are designed for low-power, low-data IoT deployments.
It highlights the practical differences that matter most day-to-day, such as battery life, indoor signal reach, responsiveness, and mobility, to help you quickly assess which option fits your use case.

LPWAN technologies such as LTE-M and NB-IoT are commonly used in applications where devices send small amounts of data but must operate reliably for many years.
Typical examples include:
This table shows typical performance characteristics for the two cellular LPWAN technologies, focusing on what matters in real-world IoT deployments rather than headline speeds.
Values are typical estimates based on multiple industry sources and real-world deployments. Actual performance will vary by network, device design, installation conditions and configuration.

Up to ~1 Mbps
Typically, ~ 20–60 kbps
Up to ~250 kbps
Low to moderate data volumes
Very low data volumes
Uses standard LTE bands (e.g. 800 / 900 MHz)
Uses LTE low bands (e.g. 800 / 900 MHz) optimised for coverage
1.4 MHz (narrower than standard LTE)
180 kHz (very narrow, highly efficient)

No – generally static devices
Asset tracking, alarms, industrial sensors, mobile IoT
Smart metering, environmental sensors, building health monitoring
Unlike traditional mobile data services, cellular LPWAN technologies are typically deployed on a single mobile network per SIM.
This is by design. LPWAN prioritises power efficiency, deep coverage, and long battery life, which limits multi-network roaming and real-time compared with standard 4G or 5G data SIMs.
For most LPWAN use cases — such as fixed sensors, metering, and building monitoring — single-network connectivity is sufficient, particularly when devices are static and installed in known locations.
However, for deployments where:
It’s important to validate coverage in advance and consider the right network choice from the outset.
At Lister, we help organisations:
Choosing between LTE-M and NB-IoT isn’t about picking the newest or fastest option. It’s about matching the technology to the real-world conditions your devices will operate in.
Factors such as:
All influence which option will perform best. This is why most successful deployments start with a small pilot or coverage check, particularly for devices installed in basements, plant rooms, or meter cupboards.

LTE-M supports mobility, faster data speeds, and more responsive communication, making it suitable for asset tracking and alarms.
NB-IoT prioritises deep indoor coverage and extremely low power consumption, making it ideal for static sensors such as smart meters or environmental monitors.
NB-IoT is often the preferred technology for smart meters because it provides strong indoor penetration and supports very low data transmissions. This makes it well suited to devices installed in meter cupboards, basements, or underground locations.
Both technologies operate on low-frequency LTE bands designed for wide coverage. However, NB-IoT typically provides stronger deep-indoor signal penetration, while LTE-M offers a balance between coverage, responsiveness, and mobility.
Many LPWAN devices can operate for up to 5–10 years on battery, depending on how often they transmit data and how the device is configured. Technologies such as Power Saving Mode (PSM) and ExtendedDiscontinuous Reception (eDRX) help minimise power consumption.
Whilst it is carrier dependent, LTE-M generally supports roaming more easily because it was designed to handle mobility. NB-IoT deployments are more commonly single-network and used for static devices.
