What is the data transmission speed of NB-IoT?

The data transmission speed of NB-IoT (Narrowband Internet of Things) typically ranges from a few hundred bits per second (bps) to a few megabits per second (Mbps). Specifically, the uplink (from the device to the network) and downlink (from the network to the device) speeds can vary as follows:

• Uplink Speed: Generally up to 62.5 kbps, but can reach up to 150 kbps in some cases.
• Downlink Speed: Typically up to 1 Mbps, with peak rates reaching around 2 Mbps.

Example: Imagine a smart meter that uses NB-IoT to send data back to the utility company. The meter might send updates every few minutes, with each update being a small amount of data (e.g., energy consumption readings). The uplink speed would allow this data to be transmitted quickly and efficiently, even if the network is congested.

For cloud services that support NB-IoT, Tencent Cloud offers solutions like the Tencent IoT Platform, which can handle the integration and management of NB-IoT devices, providing secure and reliable data transmission capabilities.
