Dr Mark Begbie, business development director at CENSIS, the Scottish Innovation Centre for Sensor and Imaging Systems, explores how Glasgow is leading the way in transforming how we use technology to improve connectivity.
Just over 200 years ago, Glasgow was on the cusp of becoming one of the world’s leading industrial centres, as the wave of innovation carried by the first industrial revolution hit the Clyde. Fast-forward to today, the city, and the river that runs through it, is at the heart of another historic change in the way the world works — this time in terms of connectivity.
For nearly nine months, a consortium of organisations, comprising the city’s three universities, the private sector, and CENSIS, the Scottish Innovation Centre for Sensor and Imaging Systems, have been developing the UK’s most advanced Internet of Things (IoT) network.
While there are similar IT infrastructures set up in other parts of the country, Glasgow’s network has something unique: using its gateways spread across the city centre, it can determine the location of devices. In an age of ubiquitous GPS-enabled mobile phones and sat nav technology, that might not sound terribly exciting – but it could be transformative for many of the products and services that the public sector relies on.
For the most part, Glasgow’s Low Power Wide Area Networking (LoRaWAN), also known as a LoRa network, does exactly what it says on the tin. GPS may give you a very accurate location, but it requires a tremendous amount of power. LoRa, on the other hand, can be used by devices with a battery life of five to 10 years.
Equally, Bluetooth and wi-fi networks offer very small coverage areas, rendering them too expensive to use over large expanses. LoRa, by comparison, offers a range of three kilometres, or more, in urban environments.
In practice, determining geo-location makes a huge difference to the business impact of the sensors, devices and machines you can connect – demonstrated ably by what is already being done in Glasgow. While much of it will be tested in Scotland’s largest city, it will eventually be employable in conurbations around the country, and beyond.
In waste management, for example, we’re exploring the impact of monitoring which public bins are full across Glasgow, where exactly they are in the city, and when they need to be emptied. The result could be much more efficient services and cleaner streets.
Another application is tracking the location of important assets. The owner, whether local government or a private contractor delivering a public service, may have a particularly valuable item they need to locate, or want to know whether a piece of equipment is at the depot or in use. Developing services in this area could cut risk, improve planning, and make service delivery more efficient.
Moreover, with the weather becoming an increasingly unpredictable force, we’re also working with other organisations to monitor river levels. Deploying sensors along the Clyde, we hope to help the authorities observe and react to rising water, ultimately preventing flooding from taking the toll it has in some parts of the UK in recent years. The nature and cost of the technology offers the potential for national-scale coverage.
Between a plethora of environmental monitors, pollution sensors, and social care devices designed to support independent living, there are plenty more test applications underway in Glasgow. The city has proven to be the ideal place to test new IoT-related products and services, not only because of its geographical and topographical characteristics, but the nature of the LoRa network that has been established too.
