Small data can be described as a building block for the IoT and the volume of data that the billions of devices lying at the edge of the Internet of Things will need a strategy for processing and analysing, writes RESHAAD SHA, CEO at SqwidNet.
The volume of data that the billions of things lying at the edge of the Internet of Things (IoT) will generate needs a comprehensive strategy for protocol mediation, processing, analysing, storing, securing, applying, and even sharing data to deliver value-creating and scalable use cases to industries and consumers. But, while trying to figure out how to manage “Big Data”, it is easy to forget that, when it comes to the IoT, it is actually the little things that matter. With the objective of maximising energy efficiency, many sensors are configured to only send small packets of data which, for convenience sake, can be called small data.
Small data is, for example, the temperature inside the storage area of a truck carrying perishable goods, sent out once every 10 minutes. It is the data relayed from a sensor placed above a parking bay that notes when the space is taken. Or the tiny packet of data relayed once a day from a water level sensor inside a reservoir, logging whether it is submerged or not. Small data gives context and enables us to identify patterns in behaviour, enabling machine learning, and driving data analytics, opening up a big world of opportunity.
The need for small data
The amount of data sent out in each case is minuscule – often no more than just a few bytes in size. And it needs to be, since larger data packets can place a heavy payload burden on the base station of a wireless IoT network that needs to connect and service millions of things. Hence, while it is easy to say “don’t sweat the small stuff”, for the IoT, it is the small stuff that truly matters. This is because all these small data packets eventually make up larger data sets from which to draw certain information. Take for example the parking-bay-sensor data mentioned earlier. Using the collected data from a parking lot over a period of months, the shopping centre management can trace a pattern of busy periods and quiet ones. This enables them to notify tenants when to run specials to attract more customers.
Even more important in future
As IoT usability expands, the reliance on small data packets that deliver more points of context become even more important. In certain use cases, a whole cascade of events will be triggered as soon as one sensor sends through specific data. One case in point is a patient being monitored at home – something we will see a lot more of as telehealth becomes more commonplace.
When accelerometer data from a wearable on an aged patient records an abrupt stop, it might indicate an injurious fall. This will trigger an automatic notification to the next of kin and the patient’s doctor. If no further movement from the patient is detected for a certain time, emergency services will be alerted to dispatch an ambulance. Furthermore, the patient’s smart home security system could also send out an access code once the ambulance crew arrives. This complete range of events is subject to the reliability of a small data sensor and a trustworthy network.
A network to depend on
To ensure the dependability of small data emanating from IoT sensors, SqwidNet, a subsidiary of DFA, is rolling out the SIGFOX IoT network in South Africa. The SqwidNet network is purpose built for listening to and delivering small packets of contextual data from these billions of connected things. Importantly, the SIGFOX standard ensures low-power usage, which is key to maximising sensors’ battery life.
Since our launch in November 2016, we have successfully deployed the network across all of South Africa’s eight major metros and we currently cover over 47% of the population. The network will exceed 85% of the population by the end of the year.
While the growth of IoT is a given, it is important to ensure that the foundations being laid now are stable and futureproof. To this end, securing small data’s place in the setup remains crucial. It its one small step for data; one giant leap for IoT.

LG G7 arrives in SA
LG this week introduced South Africa to its latest premium smartphone, the LG G7 ThinQ, focused on bringing useful and convenient AI features to the smartphone experience.
Powered by the latest Qualcomm Snapdragon 845 Mobile Platform, the LG G7 ThinQ offers 4GB of RAM and 64GB of internal storage to run demanding tasks and apps with. It is equipped with a 6.1-inch Super Bright Display, but the LG G7 ThinQ remains compact enough to use with one hand.
Sporting a new design aesthetic for the G series, the polished metal rim gives the LG G7 ThinQ a sleeker, more refined look, complemented by Gorilla Glass 5 on both the front and the back for enhanced durability. Rated IP68 for dust and water resistance, the LG G7 ThinQ is also awarded MIL-STD 810 c certification, having been subjected to a range of extreme temperature and environment tests designed by the United States military.
The LG G7 ThinQ has an 8MP camera up front, rendering clear and natural selfies, with two 16MP cameras at the back that deliver higher resolution photos with more detail, as well as a Super Wide Angle configuration.
As with other leading brands, LG has evolved its signature camera by including AI functionality. The AI CAM offers 19 shooting modes for intelligence-optimised shots. Users can also improve their photos by choosing from an additional three effect options should the AI CAM recommendation not suit their taste.
The new Super Bright Camera captures images that are up to four times brighter than typical photos shot in dim light. Through the combination of pixel binning and software processing, the AI algorithm adjusts the camera settings automatically when shooting in low light.
Live Photo Mode records one second before and after the shutter is pressed for snippets of unexpected moments or expressions that would normally be missed. Stickers uses face recognition to generate fun 2D and 3D overlays, such as sunglasses and headbands, that can be viewed directly on the display.
New to the G series is Portrait Mode, which generates professional-looking shots with out-of-focus backgrounds. This effect can be generated using both front and rear standard lenses as well as the rear Super Wide Angle lens.
LG G7 ThinQ offers further AI functionality with the inclusion of Google Lens features. Google Lens is a new way to search using the AI and computer vision. Google Assistant and Google Photos allow users to access more information on objects such as landmarks, plants, animals, and books. It can identify text or visit websites, add business cards to contacts, events to the calendar or look up an item on a restaurant menu.
A button just below the volume keys launches the AI functionality. A single tap of this button launches the Google Assistant, while two quick taps launches Google Lens. Users can also hold down the button to start talking to the Google Assistant without the repetition of the OK Google command.
With Super Far Field Voice Recognition (SFFVR) and the highly-sensitive G7ThinQ microphone, the Google Assistant can recognise voice commands from up to five meters away. SFFVR is able to separate commands from background noise, making the LG G7 ThinQ an alternative to a home AI speaker, even when the TV is on. Commands for the Google Assistant have been increased in the LG G7 ThinQ so users can get more done with their voice alone.
“The LG G7 ThinQ is strongly focused on the fundamentals and its launch marks a new chapter for our company,” said Deon Prinsloo, General Manager for Mobile Communication, LG Electronics S.A Pty Ltd. “Through the combination of personalised and useful AI functionalities with meaningful smartphone features, this is LG’s most convenient and in the moment smartphone yet.”
