p Some customers are expecting more than can be realistically delivered with licensed spectrum Internet of Things connectivity technologies, a major European telco has warned.
Suggesting that customers' expectations about what can be achieved with the Narrowband Internet of Things (NB-IoT) technology must be managed, Deutsche Telekom's Jens Olejak said: "We have some customers, large customers, who expect they can use NB-IoT for constant locating of objects.
"We've been talking to these customers, telling them, 'Guys, you have to change some of these parameters.
Olejak's remarks came as part of a panel discussion at Tuesday's LPWA conference in London on the broad topic of what telcos have learned from deploying low-powered wide area network (LPWAN) technology.
He was referring to the typical demands of Deutsche Telekom's customers from their IoT equipment: namely, ability to communicate with the network from an indoor location, running from a "small" battery and with a lifespan of at least 10 years.
Highlighting how customer feedback was that "indoor penetration was better than expected" with NB-IoT, Olejak said: "In terms of data volume... some customers realised they had to change something so it's not feasible to use more than a megabyte per month.
