Low-power wide-area networking technologies provide another important wireless connectivity options for IoT systems. It usually uses a star or point-to-point topology, and can be deployed using a cellular network infrastructure or a proprietary network infrastructure. Learn when to use this kind of networking technology in some typical scenarios.
- [Instructor] We have used the term LoWPAN…to refer to the type of wireless PANs…charting at a low rate and a very low power applications.…As there are other wireless PANs charting…at the high rate applications.…The main features of a LoWPAN are listed here.…A LoWPAN usually consists of low power and low cost devices.…For example on the IoT device…the micro processors, radio modules, sensors or…actuators need to be kept at a low cost…and to run in the power-saving mode most of the time.…
A LoWPAN usually offers low bit rates on…a communication link.…This implies the applications requiring…a fast and high rate of communication link.…Such as multimedia streaming applications…cannot be supported well in the LoWPAN.…Similar to a wireless PAN a LoWPAN usually operates…in unlicensed frequency bands.…With the above features a LoWPAN can well support…low power IoT applications.…The typical use cases of a LoWPAN…include the home or building automation applications…such as pathway control and monitoring,…smart lighting, smart metering;…
