Answer:
1. High-Power Metropolitan-Area Network ( HPMAN)
2. Low-Power local-Area Networks (LPLAN)
3. Low-Power Wide-Area Networks (LPWAN).
Step-by-step explanation:
- What is internet of things?
Internet of things, also refer to as internet of everything is the interconnection via the Internet of computing devices installed in functional objects in the environment for execution of specific task. It functions by collecting, processing data they acquire from their surrounding environments using embedded sensors, processors and communication hardware. IoT is characterized by connecting things to the internet but it is difficult to evaluate what type of network connectivity is best for a given IoT solution because there are numerous numbers of options. Examples of network connectivity are WiFi, Bluetooth, satellite, RFID, NFC, LPWAN, and Ethernet but the perfect network connectivity option must consume extremely little power, have huge range, and would be able to transmit large amounts of data (high bandwidth). The network connectivity are grouped into three major group
- High Power Consumption, High Range, High Bandwidth
To wirelessly send a lot of data over a great distance, it takes a lot of power. A great example of this is your smartphone. Your phone can receive and transmit large amounts of data (e.g. video) over great distances, but you need to charge it every 1–2 days. Connectivity options in this group include cellular and satellite. Cellular is used when the sensor/device is within coverage of cell towers. For sensors/devices that are, say, on a ship in the middle of the ocean, satellite becomes necessary.
- Low Power Consumption, Low Range, High Bandwidth
To decrease power consumption and still send a lot of data, you have to decrease the range. Connectivity options in this group include WiFi, Bluetooth, and Ethernet. Ethernet is a hard-wired connection, so the range is short because it’s only as far as the length of the cable. WiFi and Bluetooth are both wireless connections with lower power consumption than cellular and satellite and with up to or greater than the bandwidth. However, as I’m sure you’ve experienced just walking around your home, the range is limited.
- Low Power Consumption, High Range, Low Bandwidth
To increase range while maintaining low power consumption, you have to decrease the amount of data that you’re sending.Connectivity options in this group are called Low-Power Wide-Area Networks (LPWAN).
