Deutsche Telekom is preparing the roll-out of its 5G-ready LTE-M technology in 2019 with the accelerated development of LTE-M products. The company has unveiled the finalists of the hubraum LTE-M Prototyping programme at a summit in Vienna, Austria. The initiative was established by Deutsche Telekom's in-house tech incubator hubraum in cooperation with its ICT services arm T-Systems. It builds on successfully implemented prototyping programmes for NB-IoT products.
Almost 150 start-ups and IoT specialist companies from across Europe and the US submitted LTE-M-based proposals to the new programme. Eighteen partners from twelve countries spanning various industries were selected for further cooperation in prototyping LTE-M use cases. With Deutsche Telekom's support, they have implemented LTE-M connectivity and tested the prototypes in either Krakow, Berlin, Reutlingen, Rotterdam or Vienna, where local LTE-M test networks are already available. The tests were conducted to validate the first LTE-M connections for their prototypes and to explore commercial aspects.
The hubraum LTE-M Prototyping finalists have developed innovative tools in several industry sectors, most notably in the areas of smart city, wearables, e-Health and smart tracking.
Neebo in the UK, for example, has created a miniature wearable so small it can be placed around a newborn baby's wrist and monitor his or her vital signs.
The Dutch company Babbler has developed a high-value industrial asset tracking tool. It tracks cargo containers over long distances and connects them to security alarms to alert to theft or damage.
Security is also the focus for Inshoerance in Germany, which has invented smart insoles with a built-in alarm sensor which can be activated by tapping one's feet together. These safety shoes can be used by professionals in dangerous workplaces or people at risk of being kidnapped.
LTE-M can also support smart city and smart building applications, such as connecting energy meters or air conditioning, in environments which require more than the periodic one-way transmission of small amounts of data or need to be mobile.
For example, Polisens.io in Estonia has developed air quality sensors that are attached to buses and provide a holistic map of air pollution across a city.
LTE-M is specifically designed for IoT connectivity. It enables long battery lifetime and supports low-cost modules, while providing fast data throughput as well as good indoor coverage. LTE-M combines the advantages of both NB-IoT and LTE technologies, and can therefore address a different set of use cases.
When compared with NB-IoT, LTE-M offers higher data rates (up to 1 Mbps), lower latency, connected mobility (i.e. the ability of a technology to do a handover between cells), SMS support and, at a later stage, also voice (VoLTE). Its indoor coverage and expected battery life are nearly as good as that of NB-IoT. When compared with M2M (LTE), LTE-M offers much lower energy consumption and better indoor coverage, and up to 50 percent lower module cost.
As LTE-M is based on the LTE 3GPP standard, it is 5G-ready and only requires a software update in the network. 3GPP has agreed that the NB-IoT and LTE-M technologies will continue evolving as part of the 5G specifications, meaning that Deutsche Telekom can already leverage investments and continue as part of the 5G evolution. This underlines the long-term status of these technological developments.
