WHAT IS LPWAN- LOW POWER WIDE AREA NETWORK?
LPWAN is a communication method between linked devices that was founded and developed by Sigfox. The fundamental advantage of LPWAN is that it permits low-bit-rate communication among devices dispersed across a large geographical area.
LPWAN refers to a set of communication technologies (Sub 1GHz, NB-IoT, LTE CAT M, ZIGBEE) used to link devices, sensors, actuators, controllers, and so on. The goal of creating a low power wide area network is to create a communication channel for the Internet of Things network that uses less power and has a lower data rate.
Sub-1 GHz RF, as the name implies, operates at low-frequency ranges less than 1 GHz. It operates in the ISM band, which has a frequency range of less than one gigahertz. This technology is mostly relevant for RF IoT applications. Some of its advantages are as follows:
Sub-1 GHz RF has a greater range while using the same output power. Because of its vast range, it can go more than 100 kilometres.
Power usage is quite low.
Ability to deal with interference more effectively.
NBIoT, or Narrowband IoT LTE, is a self-contained LPWAN technology. It enables the mass deployment of IoT devices. NB-IoT is often used to transport data at a low frequency. When a message is sent via NB-IoT, it consumes very little bandwidth. Among the advantages of NB-IoT are:
Devices can be deployed in bulk.
Excellent choice for embedded sensors.
CAT M is another LPWAN technology that operates on 1.4 MHz of bandwidth. It enables higher total data rates, more location accuracy, and shorter latency. It allows voice calls and mobility mode. CAT M has the following advantages:
The maximum data rate is 375kbps.
VoLTE functionality is supported.
There is complete mobility assistance provided.
LTE in-band mode of operation
The IEEE 802.15.4 standard is used to operate ZIGBEE networks. It’s appropriate for high-level communication protocols. It is primarily intended for small-scale IoT projects for personal use, such as home automation, where wireless communication is required. ZIGBEE has the following advantages:
It supports several network topologies.
Battery life is extended.
Spectrum of direct sequence spread
LoRaWAN is a well-known worldwide standard for LPWAN networks based on LoRa technology. The LoRaWAN standard for low-power wireless networks was created to link devices that run on batteries. LoRaWAN allows for highly seamless information transfer over the internet between smart devices without the need for complicated installations. Some of the advantages of LoRaWAN include:
The device linked to the LoRaWAN network may send data from a distance of 1 km to 10 km.
Because AES128 is used between network servers and end nodes, it enables high-security data encryption.
A single Lora Gateway may connect thousands of devices.
Because of the adjustable data rates, it consumes less bandwidth.
LoRaWAN’s basic architecture makes it simple to deploy.
The following are the advantages of LPWAN technology:
Less power consumption: LPWAN operates at extremely low power consumption.
Long-distance transmission: LPWAN permits device connectivity across distances of up to 20 kilometres.
Long battery life: Because LPWAN requires less power, the gadget battery may last for more than ten years.
Reduced Gateways: Because LPWAN permits device connectivity over greater distances, fewer gateways are needed for communication.
