(2) Network communication technology enables objects to connect with each other, exchange data and remote control through the Internet.
(3) the data processing platform is used for receiving, storing and analyzing mass data generated by the Internet of Things equipment,And provide corresponding applications and services.
The application of Internet of Things technology is very extensive, covering smart agriculture, smart city, industrial automation, smart transportation and other fields.
4G technology is the fourth generation mobile communication technology, which provides higher data transmission rate, lower delay and more stable network connection.To meet the growing demand for mobile data.4G uses LTE technology as its core network technology to make the response time of data transmission shorter, which is useful for real-time applications.For example, remote control is very important.With the construction of more and more base stations by operators, 4G can provide stable mobile network connections in a wider area.This enables people to enjoy high-speed mobile Internet services in urban, rural and remote areas.
LTE Cat 1 technology is born for the Internet of Things, and it meets all the needs of medium-speed, low-latency Internet of Things devices.
In the process of intergenerational migration of cellular Internet of Things connection, LTE Cat 1 module takes advantage of its own advantages.It supports a terminal downlink rate of up to 10 Mbps, which enables the terminal to operate at lower power consumption and lower cost.IoT devices are connected to the LTE network, which perfectly solves the communication scenario requirements of medium-rate Internet of Things devices.
At present, the number of 4G base stations in China has exceeded 5 million.Based on this mature LTE network deployment, it can take advantage of the existing 4G infrastructure.Provides wide area coverage with low power consumption and stable signal quality,It enables Internet of Things devices to connect to cloud platforms or other remote servers through LTE Cat 1.The functions of data transmission, remote control and monitoring are realized.
LTE Cat The application of 1 mainly focuses on smart agriculture, smart city, smart home appliances, industrial sensors, hydrological and water conservancy detection, port logistics and so on.These requirements for broadband rates are not high,At the same time, it is also an application scenario with high requirements for battery power supply, power consumption and data transmission stability.
In addition to LTE Cat 1, there are other Internet of Things communication technology standards, different technical standards according to different needs and application scenarios.Different features and functions are provided.
In terms of network coverage, LTE Cat 1 can seamlessly access the current mainstream LTE network without upgrading the hardware and software equipment of the base station.The network coverage cost is low; In terms of chip cost, after many system optimizations, the hardware architecture of the module is simpler and more integrated.With the improvement of competitiveness, prices are also declining steadily. Cat, by contrast, will cost more.
The transmission rates of LTE Cat 1 and LTE Cat 4 greatly influence their respective application areas.LTE Cat 1 is applied to medium and low speed data communication services, and is suitable for industrial sensors, hydrology and water conservancy, logistics tracking and other scenarios;LTE Cat 4 is used in vehicle networking, smart grid, real-time video and other scenarios, which requires higher bandwidth and stability.
High-speed data transmission
4G LTE Cat 1 supports a higher data transmission rate, with an uplink peak rate of 5Mbit/s.The downlink peak rate is 10Mbit/s.This enables the data acquisition device to quickly and efficiently transmit the collected data to the cloud or other data processing platforms.Real-time or near real-time data transmission is realized.
Wide area coverage
The 4G LTE Cat 1 network has a wide network coverage and can achieve worldwide mobile communication coverage.This means that the data collection device can perform data collection in a variety of geographic locations and environments,And carry out remote data transmission through a 4G network.
Real-time monitoring and control: Due to the higher data transmission rate of the 4G LTE Cat 1 network,Users can remotely control the data acquisition equipment through the cloud or other terminal devices.Including setting parameters, adjusting settings, sending instructions, etc.This is very important for some applications that need real-time monitoring and remote control, such as irrigation control and environmental monitoring in smart agriculture.
Remote maintenance and upgrade: The 4G LTE Cat 1 network enables remote maintenance and upgrade of data acquisition equipment.The operation and maintenance personnel can remotely access the equipment through the network for fault diagnosis, parameter configuration, firmware upgrade and other operations.This reduces the need for on-site maintenance, saving time and cost.
High reliability and stability: The equipment usually needs to run for a long time to maintain a stable connection with the network.The 4G LTE Cat 1 network can provide a stable data transmission connection to ensure data accuracy and integrity.
