What is NB-IoT – LPWAN, why a separate network for IoT?
The full form if NB IoT is, NarrowBand Internet of the things. NB IoT is the technology to extended a device battery life and deeper coverage. In IoT, the devices connected over the Internet, to use the Internet a device uses SIM cards. A mobile phone is also an IoT device.
But the most important issue is the battery life for the IoT devices. If a company sells car tracking devices with a battery life of only a few days. It will be impossible to sell the devices and no one wants to charge or replace each month.
To overcome problem GSMA standardized new technology called NB-IoT. NB-IoT uses low power wide area network(LPWAN) technology.
What is LPWAN?
The low power wide area network(LPWAN), is a new radio type. Which provides low data transfer speed and wide coverage. Due to lower speed, it provides a longer battery life. It is estimated that within a few years there will be billions of devices connected to the NB-IoT. So LPWAN is a suitable network for the IoT devices. The new RAT type p[rovides more extended DRX and Paging Time Window timers, as compare to EUTRAN and other RAT Types.
