AT&T and Vodafone Business want to bridge the IoT divide between the United States and Europe with a roaming deal that allows customers to access to their respective narrowband IoT (NB-IoT) networks across six countries.

The operators say this will make it easier to build IoT deployments that work across the U.S. and parts of Europe. This includes AT&T’s country-wide NB-IoT network and the Vodafone networks in Spain, Germany, Italy, the United Kingdom, and the Netherlands. It will be available to customers by the end of 2019, according to the operators.

NB-IoT is a low power wide area (LPWA) network designed specifically for IoT devices that require long battery life, high-signal penetration and low data volumes. AT&T has targeted four market segment with its NB-IoT network: consumer for home sensors, appliances, and door locks; smart cities for parking garages and utility meters; agriculture for soil, wind, and air quality monitoring; and enterprise for waste management, on/off buttons, and storage container monitoring.

“For the IoT to live up to its promise, it must be global,” said Chris Penrose, SVP of advanced mobility and enterprise solutions at AT&T in a statement. “More and more of our enterprise customers are launching IoT applications across multiple countries. Working with Vodafone we can offer our customers simplified deployments to help scale their IoT plans across the U.S. and Europe.”

Vodafone’s 2019 annual IoT Barometer found that 34% of companies now use IoT, up from 29% in the previous report. What’s more, 74% of these adopters believe that within five years companies that have not adopted IoT will have fallen behind their competitors.

“We want to make technology adoption simpler for our customers to help them achieve their business outcomes and by pushing forward the standards and linking up our IoT network with AT&T’s, we’re doing just that,” added Vinod Kumar, CEO of Vodafone Business, in a statement.

The IoT partnership builds on an earlier announcement in February that AT&T and Vodafone Business are offering LTE for machines (LTE-M) roaming across their respective networks in the U.S. and the Netherlands.

AT&T added more roaming partners in June with an agreement between AT&T, KPN, Orange, and Swisscom that enabled roaming between their respective LTE-M networks in Europe and North America.

Both AT&T and Vodafone Business say they are committed to expanding their NB-IoT and LTE-M roaming footprints globally to put LPWA on a similar global footprint to 4G. NB-IoT and LTE-M are also expected to be included in the global standards for 5G massive IoT.

LTE-M and NB-IoT are the two mobile IoT technologies promoted by the GSMA, and they were standardized by 3GPP in the Release 13 specification.

At least 110 operators have launched commercial IoT networks using NB-IoT or LTE-M technology, according to GSMA. The international trade group also predicts there will be 1.9 billion LTE-M and NB-IoT connections by 2025.
