The Abeeway Micro Tracker is a pocket sized geolocation device that supports multiple location technologies. It is a small battery powered unit that can either be put in your pocket, attached to a key-ring or put inside something else.
GPS. Just the same technology as your sat-nav in your car or your smart phone uses. It relies on receiving signals from multiple satellites in orbit around the planet. Location accuracy can be as good as a couple of metres but this is dependant on getting signal from a lot of satellites, 10m accuracy is common. Even though GPS is a “receive only” system, it is quite power hungry because it takes a long time (minutes rather than seconds or even milliseconds) to lock on to multiple satellites. It’s free to use and there is global coverage. However you really need to be outside, if you are inside a building it sometimes works near a window.
LP-GPS (aka Low-Power GPS). This is a proprietary technology and requires the use of Abeeway’s own software platform. The idea is that most of the location processing is done on a server instead of the device itself so time, CPU usage and therefore battery power is saved. I can’t comment on the operation of this at the moment as I am yet to give it a try.
Wifi Sniffing. I find this technology really interesting and yet a bit scary at the same time. Because there are wifi networks literally all over the place these days, you are usually within range of several of them anywhere except remote or rural areas. Companies such as Google or Apple collect the IDs and locations of wifi networks and store them anonymously. Your smart phone makes use of this data to determine it’s own location quicker than waiting for a GPS lock, your smart phone also collects this data and sends it back to the databases of the likes of Apple and Google. The Abeeway tracker makes use of this technology as a way of getting a pretty accurate location by simply sniffing for wifi networks in range. The tracker simply sends the IDs of nearby wifi networks to the LoRaWAN Network Server. It is then up to you to convert this into a normal location (latitude & longitude) on your own application. The raw data looks like this:
That’s a list of wifi bssids and rssis my tracker has sniffed. It doesn’t connect to any wifi network, it simply scans for their IDs. Any wifi network broadcasts these ID numbers (along with the SSID you more commonly see in a list of networks to connect to on your computer). The rssi numbers are the signal strengths for each network which can optionally be used to get a more accurate location .
To do something useful with this information you need to convert that raw data into a location. Google provide an API to their mapping system called GeoLocate, it does many things but one of them is converting these wifi networks into a real location just like you’d get from GPS – a latitude and longitude.

It stands for Narrowband Internet-of-Things. It is a low powered wide area network (LPWAN) radio technology that is part of the LTE/4G family.
Essentially a cut down version of the LTE technology that your mobile phone probably uses but using a narrower bandwidth (hence the name).
It has similar design goals to other LPWAN technologies (such as LoRa and Sigfox). These are mostly ultra-low power usage, long range, low cost, small data usage.
The main difference between NB-IoT and LoRa/LoRaWAN is that an NB-IoT network is provided by a mobile network operator rather than individuals buying and operating their own gateway devices.
It’s a brand new technology, the standard was only finalised in mid-2016, as yet there are no commercially available NB-IoT services in the UK. There are some available in central Europe. At the moment, Vodafone UK are the only operator currently rolling out the service but as I understand it, O2 and EE will soon follow. The Vodafone service is currently in the trial stage and coverage is limited to certain areas of the country.
It’s my opinion that NB-IoT will become a popular LPWAN standard in years to come so I am excited to be able to give it a try. Alliot’s plan is to offer NB-IoT related services and sensors as soon as they are commercially available.
Trying out NB-IoT
As I said, Vodafone are currently trialling their NB-IoT service, this means that they are making SIMs available to certain partners for testing. I have obtained some SIMs for testing, I cannot get any for anyone else at the moment. Alliot plan to provide SIMs as soon as we can.
Because it’s so new, there’s not much hardware around at the moment that supports NB-IoT. So to test I have so far bought a Pycom Fipy development board:
The NB-IoT node will send and receive data via the network operator’s network, they will assign an IP address to the node and it can then communicate with the Internet. To test, you will need a server/computer that is publicly accessible on the Internet. In my case, the Vodafone trial limits usage to UDP only so I made a simple Python script on a test Amazon AWS server that accepts UDP packets and logs the contents to a file. All very simple stuff and not very useful but it’s pretty cool all the same! It all works as expected.
The Pycom board simply sends a “hello world” message every ten minutes, the Arduino board does this too but I also made it report it’s battery voltage since I’m powering that from a rechargable LiPo battery.
What next, what use is this?
I’ll expand on this to connect some real sensors to both devices so they are sending something more useful. I will then make the server part log to a database and produce some graphs in Grafana to visualise the data.
I have also sourced some commerically available sensor devices so will be testing them, another post on that will follow.
Verdict on NB-IoT testing
This experimentation has taught me a few things.
This is very new technology indeed, it’s much less mature than LoRaWAN for example. There’s scant information on the Internet so far, getting the Arduino board to work for example involved finding and reading the low level documentation for the uBlox chip on the board and the Arduino source code for their NB-IoT library.
You’re at the mercy of a network provider. If you have no coverage then it’s tough luck, no buying a gateway as with LoRaWAN or Sigfox. Although if there is coverage, then great, you don’t need to buy a gateway (also the case for Sigfox). You will always have to pay a network operator for use of the network.
It needs more power than LoRaWAN, considerably so in my opinion. For example, just connecting to the network takes multiple seconds and this will eat batteries. In comparison to LoRaWAN where a sensor can wake up, fire off a message and go back to sleep in a matter of milliseconds. Feel free to get in touch and correct me but I cannot see how NB-IoT can be anywhere near as frugal as LoRaWAN.
It’s more synchronous than LoRaWAN. It’s still designed for tiny amounts of data but connections involving multiple requests & their responses are possible. A protocol called Constrained Application Protocol (CoAP) can be used which is like a cut down version of HTTP.
The technology is a reality and the mobile networks are starting to roll it out. I think NB-IoT will be big and sit alongside other LPWAN technologies.
The UK seems to be behind central Europe again. There’s much more evidence online for people using NB-IoT in places like Germany.

LoRaWAN technology has a wide range of applications. The sky is the limit when it comes to creating LoRa IoT solutions to help your business run more smoothly. This blog post covers a few examples of how different types of LoRa sensors can be used, and some of the advantages of switching to LoRa technology.
Smart Metering / Energy Monitoring
Reduces the need for traditional manual processes allowing instant, remote updates of electricity, gas, water & heat consumption.
Retrofit sensor systems to existing client infrastructure.
Improve efficiency by highlighting and targeting areas of unusually high energy consumption.
LPWAN technology is perfectly suited for environmental monitoring due to the wide range of solutions available. Gather data on temperature, humidity, light, air quality (carbon dioxide, PM2.5 etc), smoke detection & water quality to name but a few.
Carbon monoxide sensors for homes managed by others such as Housing Associations or landlords to ensure the occupants are living in safe conditions.
Transport & Asset Tracking
In the realm of transport infrastructure, railways are big users of sensor networks. These can be used, for example, to monitor potentially damaging vibrations in bridges, through deformation of the tracks, to movements in embankments that could indicate potential collapse.
Keeping track of anything from logistics equipment (trolleys, fork lift trucks etc) right through to entire fleets of vehicles by installing a discreet, long lasting GPS tracker. The sensor not only tells you the location of the equipment in real time, it can also ensure they are being used more efficiently which could in turn assist with fleet management & inventory decisions.
Even agriculture gets in on the act, with smart farms monitoring soil moisture levels and crop health, providing machinery diagnostics, keeping an eye on crop storage conditions and tracking & monitoring livestock.
Temperature sensors could be used to ensure the optimal conditions for Chicken Farmers to maximise their yield.
A smart sensor system can help maximise a farmers yield therefore reducing water consumption, optimising the use of fertilizers and pesticides which increases production & lowers costs.
BT have announced they are launching a Smart Water project with Northumbrian Water which will be deployed across Sunderland, with around 150 sensors installed to capture water flow, pressure and quality enabling Northumbrian Water to gain visibility into operational insights.
Just last month water meters were deployed across the south east to gather real time information on water capacity levels, consumption and pass through; this is fed back to Icosa Water via a smart metering platform.
Beer Keg Supply Chain Optimisation
A novel application developed at the University of Wollongong in New South Wales, Australia, involved fitting smart sensors to beer kegs. Called the Binary Beer project, it uses LoRaWAN to transmit the fill levels and environmental conditions of kegs back to the brewer in real time.
The IoT landscape continues to develop. More and more infrastructure is being added, most recently (24/7/2019) Norfolk County Council’s Digital Innovation and Efficiency Committee has approved a proposal to launch a LoRaWAN network to enable early adopters to test IoT (Internet of Things) applications.
The proposal includes a number of Gateways around Norwich connected to The Things Network that will receive information from Sensors placed around the city.
It does not take long to set up a LoRaWAN network either, everything should be in place by September 2019.
To the uninitiated IoT can be seen as a dark art when the reality paints a very different picture, especially when you have the right partner.
The kit list can be broken down into the following categories;
Nodes / Sensors –
These are the devices that will collect & transmit the data
Concentrator / Gateway –
These will collect the data signals and send it to…
Network Server –
This collects all of the data via the Concentrators / Gateways and links that data to an…
Application Server –
Which interprets the data that can then be reviewed against a set of tolerances and can be used to automate actions based on the data that has been received, for example triggering an alarm.
