Lets look at IoT in the beginning. When modems were modems and GSM was the standard, 9600 baud, with provenance back to <\/span>Emile Baudot<\/span><\/a>, the inventor of one of the early telegraphic codes, creating a yardstick for data communication. One baud (Bd) is one bit per second (b\/s). \u00a0\u00a0Early IoT was a mixture of data-over-GSM. (Remember AT commands? Another thank-you and acknowledgement to <\/span>Dennis Hayes<\/span><\/a> \u2013 names which are part of the near forgotten start of the internet.)<\/span><\/p>\n

The point is \u2013 there wasn\u2019t much of a data rate, so, the idea of sending data was tricky. \u00a0Remote devices tended to be \u201cthings\u201d such as water level meters, alarms, power billing, asset tracking. \u00a0Because it was hard to establish a data session, a lot of data used to be transmitted by SMS \u2013 a quirk of mobile communications. \u00a0SMS was an almost accidental byproduct of designing a GSM service. It was a way of sending 160 characters to-and-fro over the mobile network via a protocol which is unknown to many \u2013 \u201cSS7\u201d or Signalling System No.7.<\/span><\/p>\n

SS7 is still in use across the globe and a lot of the messaging which isn\u2019t Whatsapp or iMessage is SS7. \u00a0It\u2019s simple, robust and just works. However, with a small payload of 160 characters (or multiple lumps of 160 characters), it\u2019s really only useful for a remote sensor to say \u201cI\u2019m too hot\u201d, \u201cI\u2019ve used this much power\u201d, \u201cI\u2019m here\/there\u201d, or \u201cI\u2019m broken \u2013 please fix me\u201d. \u00a0This was the earliest IoT \u2013 mostly around monitoring of remote devices. <\/span><\/p>\n

However \u2013 as we progressed from GSM, to GPRS (General Packet Radio Services), we now had the luxury of many tens of kilobits per second (!). But most importantly this was a continuous data stream, and so it was possible to have two way data dialogues \u2013 and to manage the overhead of encryption within that dialogue. \u00a0Now we had devices saying \u201cI\u2019m too warm, please tell me what I should do?\u201d i.e to move from monitoring, to monitoring and control. Now we have open loop systems, where the smart decisions are not being made on the device, but by a centralised system. This has revolutionised IoT from an intelligence perspective, because centralised decisions can be made which allow the control of a myriad of devices in the field. For example \u2013 the device may say \u201cthe water level is too high in the reservoir\u201d \u2013 the answer from the central system \u201cplease open the sluice gates and discharge water downstream\u201d. \u00a0<\/span><\/p>\n

This is a revolution, but if the wrong reservoir was emptied (or multiple reservoirs) at the wrong time, towns could submerge or worse. \u00a0As this technology was embraced, what was a commodity industry of \u201cmobile connectivity\u201d became more important. As our own group of telecoms operators have evolved over the last two decades, we\u2019ve strived to create secure-by-design services, which provide an extra layer of control and assurance. \u00a0As long ago as 2008, we created a remote connectivity service, which could allow, via an API , for our partners to configure end devices to only communicate back to their control platform. This layer of extra security helps to provide part of the defence-in-depth approach to securing the devices which control our cars, wind turbines, traffic signals and health monitoring.<\/span><\/p>\n

At the same time as we\u2019ve built this security into our systems, we\u2019ve also realised it\u2019s had some great peripheral benefits. For example, we can provide SIMs for innovation \u2013 secure data SIM cards which can only talk to the control platform for the device, building in an extra layer of security to the innovator. \u00a0We\u2019re now starting to see the industry not just want low-cost connectivity to remote devices, but the recognition of the importance of secure connectivity.<\/span><\/p>\n

Talking of innovation, we\u2019ve been working alongside the Leeds City Region where we are based. Over the last 5-10 years, we\u2019ve seen a growth in the ecosystem, including the <\/span>Open Data Institute Leeds node<\/span><\/a>. It\u2019s this journey that is creating a connected society, changing the world with tech advances that are truly transforming the world we live in.<\/span><\/p>\n
