How does MQTT help IoT devices communicate with each other?

Vaibhav Kothia May 26, 2023 0 Comments

MQTT is a lightweight messaging protocol designed specifically for use in IoT networks. It is an open protocol that enables devices to communicate with each other over the Internet in a secure and reliable way. The protocol is designed to be lightweight and efficient, making it ideal for use in IoT networks with limited resources.

MQTT helps IoT devices communicate with each other by providing a simple and reliable messaging protocol. It uses a publish/subscribe model which allows devices to communicate without the need for direct communication between them. For example, a temperature sensor can publish its readings to an MQTT broker, and any other device connected to the broker can subscribe to the readings and use them as needed. This makes it easy for devices to share information without the need for complex networking protocols.

What are the main differences between LoRaWAN and other wireless technologies?

LoRaWAN is a low-power wide-area network (LPWAN) protocol designed for use in wireless sensor networks. It is based on the LoRa modulation scheme and provides a long-range, low-power communication solution for the Internet of Things (IoT).

Compared to other wireless technologies, LoRaWAN has several advantages:

1. Long Range: LoRaWAN has a much longer operating range than other technologies such as Wi-Fi, Bluetooth, and Zigbee. It can provide coverage up to 15 km in rural areas and up to 5 km in urban areas.

2. Low Power: LoRaWAN requires very low power consumption, making it suitable for battery-operated devices. This can result in longer battery life and lower maintenance costs.

3. Low Cost: LoRaWAN devices are relatively inexpensive compared to other wireless technologies. This makes it an attractive solution for applications with a large number of devices.

4. Security: LoRaWAN provides strong encryption and authentication to protect data transmitted over the network.

5. Scalability: LoRaWAN is highly scalable, allowing it to support a large number of devices. This makes it suitable for large-scale deployments.

What is the purpose of TCP/IP?

Vaibhav Kothia May 26, 2023 0 Comments

TCP/IP, or Transmission Control Protocol/Internet Protocol, is a set of communications protocols used to connect hosts on the Internet or a network. It is the primary set of protocols used to connect computers to the Internet. TCP/IP is responsible for ensuring that data is correctly formatted, addressed, transmitted, routed, and received.

For example, when you type a website address into your browser, the browser uses the TCP/IP protocol to connect to the website’s server. Once connected, the browser sends a request for the web page, which the server then sends back to the browser. The browser then displays the page on your screen.
