When deploying and sustaining an IoT fleet, one of the crucial essential choices you’ll make is your selection in connectivity. It impacts the battery life, roaming location, and total reliability of your units.

On this put up, we’ll evaluate two of the most well-liked IoT connectivity choices, LoRaWAN and NB-IoT. By the top of this put up, it is best to have a strong concept of which is true in your fleet.

What’s LoRaWAN and What’s NB-IoT?

First, let’s begin with a breakdown of those LPWAN applied sciences. LPWAN, brief for Low-Energy Broad Space Community, describes low-data, low-power networking applied sciences which have primarily been designed to swimsuit the wants of IoT.


Brief for Lengthy Vary Broad Space Community, LoRaWAN is an IoT connectivity answer constructed to maintain battery-powered units linked to the web. Somewhat than concentrating high-bandwidth connectivity in a smaller vary, it covers a bigger vary at the price of smaller knowledge packets.

Since IoT units usually solely must ship small packets of information periodically, it’s properly suited to this objective.

One downside of LoRaWAN, although, is that it’s proprietary. Customers might want to pay a small payment to entry LoRaWAN connectivity, which might restrict its availability in sure conditions.


Brief for Slender-Band IoT, NB-IoT is one other connectivity answer particularly designed for the IoT sector. It helps maintain small, low-power, short-range, low-data units linked to the web. And in contrast to LoRaWAN, NB-IoT is extra specialised for stationary units.

One of many key variations between LoRaWAN and NB-IoT is that NB-IoT is constructed on present LTE infrastructure. This makes it simpler to deploy, normally extra reasonably priced, and extra obtainable.

NB-IoT can be a proprietary expertise, so once more, customers might want to pay an extra payment to entry NB-IoT options.

What Are the Technical Variations Between LoRaWAN and NB-IoT?

As you might have realized by now, LoRaWAN and NB-IoT are very comparable applied sciences. The variations between them are largely technical. That can assist you higher distinguish between the 2, listed below are the important thing technical variations between them.

LoRaWAN Consumes Much less Power Total

LoRaWAN is healthier by way of energy consumption. Customers can rise up to fifteen+ years of battery life from units linked to a LoRaWAN community. NB-IoT, then again, solely affords 10+.

This decreased energy consumption additionally makes LoRaWAN excellent for units that require larger refresh charges, as it’ll reduce the affect these larger refresh charges have in your battery utilization.

Past that, LoRaWAN has few benefits over NB-IoT. The 2 connectivity choices are largely the identical relating to geolocation and peak knowledge throughput.

NB-IoT Offers Higher Protection and Decrease Latency

Whereas NB-IoT doesn’t fare as properly with battery life, it does present higher protection and latency total. You’ll have the ability to deploy in additional areas with much less effort.

And because of NB-IoT’s low latency, you possibly can ship bigger packets of information quicker. So for units that must transmit a bigger or extra constant knowledge stream, NB-IoT is the way in which to go.

Moreover, NB-IoT is safer than LoRaWAN. It makes use of 256-bit 3GPP encryption versus LoRaWAN’s AES 128-bit encryption. So if the info you’re transmitting is delicate, then NB-IoT is a extra dependable possibility.

When Ought to You Use Which Expertise?

To a sure extent, LoRaWAN and NB-IoT are comparatively interchangeable. Nonetheless, there are just a few use circumstances the place one outperforms the opposite. Right here’s a fast record of these use circumstances to assist your decision-making.


LoRaWAN is especially good at supporting static outside units. This consists of IoT fleets used for:

  • Good agriculture
  • Good house and constructing automation
  • Warehouse monitoring

Customers can benefit from LoRaWAN’s long-lasting battery life to set and overlook outside IoT units, as it’ll assist cut back the upkeep concerned. And whereas it could work in some indoor settings, it’s greatest to not use LoRaWAN in dense environments.


Conversely, NB-IoT works exceptionally properly in dense settings. It may well penetrate partitions, buildings, and extra with out little affect on service high quality. For that cause, it’s the higher possibility in these conditions:

  • Good road lights
  • Water and electrical programs
  • Good parking

As you possibly can see, every use case is about in an city panorama, with partitions, concrete, and different wi-fi customers to cope with. Even nonetheless, NB-IoT stays a dependable and profitable answer in these cases.

Typically, Both Will Get The Job Executed

There are some conditions the place one is simply nearly as good as the opposite. This consists of:

  • Utilities and good metering
  • Logistics and asset monitoring
  • Industrial manufacturing
  • Wearables & pet monitoring
