Helium is the largest active decentralized IoT network today. There are nearly 300,000 hotspots worldwide and the number continues to increase every day.
Before diving into the details, let’s take a quick look at all the devices to date that use the Helium network. Most of the Helium-related products are sensors or sensor-based solutions that transfer or utilize small amounts of data passed over the network. For instance a sensor might monitor air quality or temperature. This data is transmitted to a Helium hotspot and then across the Helium network.

Advantages of using the Helium Network
Helium provides a global IoT network of hotspots. Being a part of the Helium system means you can collect and transfer data from helium devices anywhere in the world. For instance you can make air quality measurements anywhere your sensors are deployed. Previously the only option was to use cellular infrastructure like 3G or 4G.
One big advantage is cost. Every 24 bytes sent on the Helium network costs 1 Data credit = $0.00001. On an LTE network, 24 bytes costs $0.000072. So the cellular network is seven times as expensive. Also unlike traditional wireless networks, the Helium Network has no annual fee and you only pay for data you use. Finally with cellular you have to get a different plan depending on the country you’re in and that can complicate things. Helium is global so your data credits apply anywhere in the world.
Disadvantages of using the Helium Network
The Helium network is growing fast. We should exceed 300,000 hotspots soon. However there are major gaps in coverage. Take a look at the USA for instance. There’s a high concentration of miners (indicated by the green colored regions) in major metropolitan areas like San Francisco for instance and very spotty coverage in many states – for example Wyoming, Idaho, Nevada and Utah.
As the HNT rewards associated with coverage go down, there will be fewer and fewer incentives for people to add and maintain hotspots in the future. As a result, these major coverage holes could go unfilled. That means you will not be able to use sensors in these locations. You will also not be able to track a lost motorcycle or lost pet using Helium trackers in these areas.
The two things that will change things is if either
- the price of Helium continues to appreciate to offset the reduction in rewards or
- network use increases significantly as miners are compensated for transferring data.
At the present time the network is very unstable. It’s early days for many hotspot manufacturers and device operation is as yet unreliable. Often times I find my miner goes offline despite having a reliable Ethernet link at the back end. This might be fine in areas with high miner concentration like New York City, where if one miner goes down there are others that can pick up the job of transferring data. But it doesn’t work well in areas where there’s only one miner across a large geographic area.
The Helium network is growing rapidly as are the number of devices that are being designed to operate on it. In this post we have provided a list of devices. This is the first global IoT network of its kind and all signs are pointing to future growth. Developing for this network is not without risk and in this post we have also provided some pros and cons of investing in it.
