Small data crucial to IoT

Published

on

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.

Appdate: No wallet? No problem?

In his app roundup, SEAN BACHER highlights VodaPay Masterpass, Charge Running, South African App Integrator Directory, uKheshe Health and LocTransie.

VodaPay Masterpass

Digital mobility is now a way of life and most are using smartphones to pay bills. 

To meet this need Vodacom and Mastercard have launched VodaPay Masterpass, which enables Vodacom customers to load any bank card into a secure digital wallet, downloaded as an app on their smartphone. Once loaded, these cards and the secure credentials associated with them are safely stored, enabling customers to start transacting immediately without the hassle of entering card details each time they make a purchase.

Vodacom customers can buy prepaid data, airtime and SMS, or voice bundles, directly through the app. They can also select the Pay Bills menu option to settle their DStv accounts, pay a utility bill or take care of a traffic fine.

With the app’s Scan to Pay functionality, users can scan a QR code to pay for goods and services wherever Masterpass is accepted, including all SnapScan and Zapper merchants. Once a QR code is scanned, users select the card they wish to use, and enter their bank PIN number on their own device to complete the transaction.

Platform: Android and iOS

Expect to pay: A free download and users will not be charged for any transaction fees.

Stockists:  Download VodaPay Masterpass for iOS here and for Android here.

Charge Running

Most running apps track data like pace and distance and, in some cases play audio designed to motivate you, but don’t give you the push you get when you run with a friend. Charge Running is an app that lets you run alongside other runners, virtually, as well as giving live coaching to help you go the distance.

The app includes features such as:

·       Unlimited access to live running classes and virtual races  

·       The ability to compete with runners anywhere in the world in real-time

·       A live leaderboard that shows where you are in the pack to keep you pushing

·       Live, personalised feedback from professional trainers 

·       Group chats with coaches and fellow runners throughout the run

·       On-demand runs for times when you can’t join the live groups 

·       A choice of difficulty levels and race types 

Platform: Android and iOS

Expect to pay: A free seven-day trial; thereafter R150 per month

Stockists: Visit the Charge Running site here for downloading instructions.

South African App Integrator Directory

The South African App Integrator Directory from Xero is designed to solve the complexity of choosing apps for small business owners.

The directory is now available in South Africa with six partners, including Realm Digital, Radical Cloud Solutions, Nimacc, Insights, Iridium Business Solutions and Creative CFO. According to Xero, these are all organisations with a proven track record of successfully integrating marketplace apps into Xero businesses. There are also currently over 700 apps in Xero’s App Marketplace worldwide, 21 of which are South African born.

As small businesses become more tech-savvy, they need to know exactly which apps to install on their devices and how the apps will help them. They also need to be able to install these apps from a trusted integrator so they know for what they are paying. 

Platform: Any device with an up-to-date Internet browser.

Expect to pay: A one month trial version is offered, after which the App Integrator ranges from R125 to R245 per month, depending on the company’s needs.

Stockists: Visit Xero here for downloading instructions.
