What are the advantages of domestic LoRa module technology?

At present, point-to-point wireless star network communication cannot effectively solve the 1 km invisible wireless transmission of equipment in a building, a community, an industrial park, or an urban village in the market. The market feedback that the domestic LoRa module technology of the ten-level routing can effectively solve the problem of the nearest 1km of the Internet of Things, with low network cost and large communication distance coverage. The domestic LoRa module technology is mature, the networking technology is simple, and the embedded R&D personnel requirements are low. favored by the market. LoRa module technology has the following advantages:

Briefly describe the functions of domestic lora modules

The domestic lora module is an ultra-long-distance wireless transmission scheme based on backbone spread spectrum technology. At present, there are free frequency bands such as 433, 868, and 915MHz in the world. Lora module communication technology is characterized by high sensitivity, long transmission distance, low power consumption, and many networking nodes. Mainly used in the Internet of Things industry, such as wireless meter reading (electricity meter/water meter), industrial automatic control, environmental monitoring, environmental monitoring, etc.

Principles of visible light communication

Principles of visible light communication

Visible light communication (VLC) is a technology that offers significant advantages over the more commonly used radio frequency (RF) in some applications. Aside from its obvious use for data transfer from one point to another, VLC has attracted a lot of attention for its ability to provide a highly accurate and secure indoor positioning system. Implementing a VLC system presents specific challenges involving system integration and power management, especially for those unfamiliar with the technology. This article will explore some applications of VLC, including the principles of the VLC positioning system, and discuss how the latest devices provide a minimal risk design path.

How TurMass™ is made

How TurMass™ is made

TurMass™ adopts the original mGFRA technology, which can be regarded as the combination of multi-channel time slot ALOHA and massive MIMO receiver. The core idea is to use frequency division multiplexing and space division multiplexing to support parallel access of a large number of users. The system is divided into multiple channels, and each user randomly selects a channel for pilot and data transmission. On each channel, the gateway uses the received pilot signal to obtain the channel estimation of each user, and then uses beamforming to demodulate the superimposed user data signals, thereby recovering the data sent by each user. The complete process of mGFRA includes signal transmission at the user end and signal processing at the gateway end: 1) The terminal randomly selects the pilot; 2) The terminal randomly selects the channel; 3) User detection and channel estimation; 4) Beamforming and signal demodulation.
