Does NB-IoT provide both uplink and downlink communication?



  • NB-IoT supports bidirectional communication, but the more common direction is uplink transmission. Only half-duplex is supported, i.e. uplink and downlink don’t take part simultaneously.

    • UL peak rate up to 230 kbps
    • DL peak rate up to 250 kbps

    Please note that these are not the datarates meanwhile. Current datarates are maximum 20Kbps UL/DL due to single tone transmission.
