What is the Internet of Things?

What is the Internet of Things?

The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected, and interacted with through various devices and technologies such as information sensors, radio frequency identification technology, global positioning systems, infrared sensors, and laser scanners. , and the collection of various required information, such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., as well as the ubiquitous connections between things and people through various possible network access. The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc. It enables all independently addressable common physical objects to form an interconnected network.

Introduction to domestic RF chip knowledge

Introduction to domestic RF chip knowledge

Strictly speaking, domestic RF chips generally refer to chips that transmit and receive RF signals. In mobile phones, they are approximately equivalent to baseband chips. But signal transceiver and modulation and demodulation are two necessary links, so put the above two functions together into one chip, which is the baseband chip. The baseband chip is small in size and low in power consumption.

Faced with so many lora mods, how to choose?

Faced with so many lora mods, how to choose?

Lora module technology breaks the balance between transmission power consumption and transmission distance, and changes the situation in the field of embedded wireless communication. It presents a new communication technology for people, which can achieve long distance, long battery life, large system capacity, and low hardware cost, which is exactly what the Internet of Things needs. However, there are various types and choices of lora modules, so how to make a choice in the face of so many modules?

Domestic lora module manufacturers: What are the characteristics of domestic lora technology?

Domestic lora module manufacturers say that the LoRa network is mainly composed of terminals (built-in LoRa modules), gateways (or base stations), network servers and application servers. Its network architecture is a typical star topology. In this network architecture, the LoRa gateway is a transparent transmission relay that connects the terminal device and the back-end central server. Terminals communicate with one or more gateways using a single hop. All nodes in the gateway communicate bidirectionally with the gateway.
