6 Low-Power Wide Area Networks (LPWAN)
What are the characteristics of LPWAN?
- long range - low data rate - connect things - things that operate with battery (low power) - low cost
What are the data rate of LoRa?
0.3Kbps - 27Kbps
What is LoRaWAN?
A cloud-based MAC protocol that acts as a network protocol; management of the communication between gateways and end devices.
What is NarrowBand IoT (NB-Iot) based on?
A subset of LTE standard, Licensed LTE bandwidth
How does the devices in the LoRaWAN work?
Devices are asynchronous and they transmit to multiple gateways.
Where is NB-IoT and LTE-M from?
From 3rd Generation Partnership Project (3GPP)
What are the use cases of NB-IoT?
Highly optimized energy efficient applications.
What are the difference between LTE-M and NB-IoT?
LTE-M have higher data rate, mobility, bandwidth and cost, and support voice.
What are LoRa?
License-free sub-gigahertx radio frequency bands
What are the coverage of LoRa?
More than 10km
What is included in the LoRa physical layer?
Variation of Chrip Spread Spectrum (CSS) and FEC codes
What are the use cases of LTE-M?
Wide range cIoT applications with mobile support
Where is data forwarded in LoRaWAN?
to application servers
