DNA’s IoT service capabilities has been further enhanced, with the LTE-M technology for real-time, bidirectional IoT services now widely deployed in DNA’s mobile network. Both LTE-M and NB-IoT are now available in DNA network in Southern, Western and Central Finland.
DNA IoT customers now have two LPWA (Low Power Wide Area) options to choose from to select the technology best-suited to their needs to increase the lifespan, energy efficiency and cost efficiency of their IoT devices.
The LTE-M technology enables significantly higher data transfer speeds and volumes for IoT services. LTE-M can transfer data symmetrically both ways at an maximum rate of 1 Mbps. LTE-M is well-suited to real-time use, because the delays are remarkably short (10–15 ms) compared to the NB-IoT option (1.6–10 s).
Just like normal mobile phones, devices connected to LTE-M can move from one place to another without losing the data connection. Typical use cases for LTE-M include logistics and security systems, as well as safety bracelets for the elderly. The advantages of the NB-IoT technology include low energy consumption and high reliability in areas with coverage challenges.
