Which of the following describe LPWAN's drawbacks?

LPWAN has a number of drawbacks and is not suitable for high data rate applications because it only supports modest data rates. It provides extremely long latency between end-to-end nodes. LPWAN is hence not the best choice for low latency applications. For more details, see the LPWAN technologies' corresponding drawbacks.

Why is MQTT the ideal protocol for Internet of Things?

The finest messaging technology to use for your IoT network is without a doubt MQTT. It is affordable, quick, light, and scalable. Although MQTT has some security concerns, a partnership with a dependable cellular provider may guarantee that your IoT network uses MQTT securely and without any problems.

Describe the LoRaWAN module.

Modules for LoRaWAN. A Low Power Wide Area Network (LPWAN) specification called LoRaWAN is designed for wireless, battery-powered devices that are connected to local, regional, or international networks. LoRaWAN focuses on important IoT requirements including geolocation services, mobility, and secure bi-directional communication.

Does LoRaWAN require a SIM card?

A wireless protocol called LoRaWAN uses low power, great range, and slow data rates. In the Americas/ANZ it operates at 900MHz, while in Europe/Asia it operates at 868MHz. No SIM card is needed to access these networks; only a LoRaWAN radio and individual ID are needed.

Utilizes AWS MQTT?

Device connections that use the MQTT protocol and MQTT over WSS protocol and that are identified by a client ID are supported by AWS IoT Core. The suggested methods for connecting devices to AWS IoT Core are supported by the AWS IoT Device SDKs.

Do NB-IoT devices need SIM cards?

With our 4G LTE-M/NB-IoT devices, you'll need a SIM card that works on these networks in order to connect to the internet. It can be confusing to use different designations for the same network; for example, Cat-M1 and LTE-M are often used interchangeably.
