What is the principle of the 4G module?
The wireless technology carried by the 4G LTE module gives the communication module high spectral efficiency, high speed, low latency, low cost, and other characteristics. The 4G module integrates high-quality voice and broadband data, integrates multiple operator services, and has an advanced integrated mobile bandwidth wireless system.
What is the transmission rate of the 4G module?
Calculated at the maximum serial port transmission baud rate of 115200, considering the influence of the speed of the wireless network, it is usually greater than 100KB. In fact, faster speeds can only guarantee shorter delays.
What is the dial-up principle of the 4G module?
The download speed of the 4G LTE system is 100Mbps, which is 50 times faster than the dial-up network, and the upload speed can reach 50Mbps, which can meet the needs of most users for wireless services. On the other hand, 4G LTE Advanced uses carrier aggregation technology to achieve a peak downlink speed of 150Mbps. In addition, 4G can be placed in areas not covered by DSL or cable modems, thereby expanding to the entire area.
Obviously, 4G has outstanding advantages. The 4G module is PPPD/RNDIS/ECM dialing mode. The user issues a special RNDIS dialing command, the handheld terminal and the network start signaling negotiation, and then allocate IP addresses to complete the work together.
Purpose of 4G module
1. 4G module is used to collect office data of express cabinets in real time, monitor the safety of express cabinets, and provide 24-hour uninterrupted real-time stable transmission, which reduces the working capital of express companies and improves service capabilities.
2. 4G module is now widely used in automotive video surveillance, handheld tablets, industrial routers and other fields.
3. The charging pile is connected to the 4G module, and quickly transmits a large amount of real-time data and real-time monitoring information to the office center and users, and optimizes the handling of loose charging stacking, saving manpower and material resources, thereby achieving low cost.
4. Self-service terminal equipment requires a large amount of data to be transmitted by the network. Through the 4G module high-speed network, all terminal transaction data and equipment operations are transmitted to the transaction center in real time, thereby reducing the operating capital and planned processing operations of the transaction center.
