What is NB-IoT – LPWAN, why a separate network for IoT?
The full form of NB IoT is the NarrowBand Internet of 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 them each month.
To overcome the 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 its 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 IoT devices. The new RAT type p[rovides more extended DRX and Paging Time Window timers, as compare to EUTRAN and other RAT Types.
