T-Mobile US Inc (NASDAQ:TMUS) is planning to launch an Internet of Things (IoT) network by mid-2018.

T-Mobile says that its decision to focus on IoT comes after the completion of successful tests for Narrowband tests. Narrowband is a network for IoT that uses small amounts of dedicated spectrum to transfer data. This is possible because IoT devices don’t require large amounts of data for use.

T-Mobile notes that the live tests of Narrowband IoT took place on its networks in Las Vegas. The company also mentions that these tests took place with the help of Qualcomm, Inc.(NASDAQ:QCOM) and Telefonaktiebolaget LM Ericsson (NASDAQ:ERIC). Now that the tests are done, TMUS is preparing to launch the new network for IoT devices.

“By investing in Narrowband IoT now, we’re ensuring our customers will be able to bring their products to market faster with better performance, vastly improved battery life and big cost savings — all on a dedicated highway that’s purpose-built for connected devices,” Neville Ray, Chief Technology Officer for T-Mobile, said in a statement.

T-Mobile is hoping that IoT will continue to grow and that it will be offering its network to a large amount of customers. Data from Gartner says that there are currently 8.3 billion IoT devices in the world. It expects this number to increase to 20.4 billion by 2020.

T-Mobile also announced that it is already working with the city of Las Vegas to set up a IoT network in the city. This will include Narrowband IoT and several devices that will help the city monitor and control water, lights and other parts of the city.
