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.
