Finnish network operator Elisa recently announced that they have created a new record for the world's 4G mobile network speed. It is worth noting that they are using Huawei technology to create new records. Elisa said in the report that they have made the speed of 4G mobile networks reach 1.9Gbps. In theory, it takes only 44 seconds to download a Blu-ray movie on a very high-speed mobile network. Analysts believe that such a high speed is a bit difficult to become a reality on the real network.
At present, the fastest commercial network speed is only 300Mbps, and Elisa is six times faster. ElisaCEO Mattila said: "As far as we know, no network has achieved such a high speed so far."
In February of this year, a university team had made the 5G mobile network speed 1Tbps. The team has nothing to do with any network operator. It is 50 times faster than the Elisa 4G network.
In an interview with the BBC, Matila said that 1Gbps mobile networks will be launched in Finland in the next two or three years. Matila believes that with ultra-high-speed networks, mobile VR, AR and high-quality 4K video will have better opportunities for development.
Still, two analysts still doubt the practicality of ultra-high-speed networks in the real world. Nick Wood, assistant editor of international communications professional media, Total Telecom, said: "Deploying a network that can support 1.9Gbps ​​speed does not mean that customers can get 1.9Gbps ​​of mobile bandwidth. Why? Because of network capacity Need to be assigned to different customers. In the real world, customers will feel a moderate increase in overall network speed, stability will be improved, but not as exciting as 1.9Gbps."
Ernest Doku, a uSwitch telecommunications expert, points out that if we play streaming HD content on Netflix, the speed of the network will be as long as 5Mbps, and Elisa is 400 times faster. He believes: "It will take a long time for the UK infrastructure to provide such a high speed." Doku said that Elisa's new record shows that 4G has great potential to tap.
Matila believes that Elisa's record-breaking proves that 4G networks can continue to evolve and bring better download speeds to mobile customers. He said: "5G technology is still in the early stages of development and will soon be tested in the technical world. If 4G can run faster, we don't need to use 5G for the time being. According to my personal prediction, there will be 5G next year. Network trial operation, 5G large-scale deployment may be postponed after 2020."
Sensors can be classified into various types based on their functionality and application. Some common sensor classifications include:
1. Temperature Sensors: These sensors measure and monitor temperature changes in the environment or in a specific object. They are commonly used in weather stations, HVAC systems, and industrial processes.
2. Pressure Sensors: Pressure sensors are designed to detect and measure changes in pressure. They are used in applications such as automotive systems, medical devices, and industrial machinery.
3. Proximity Sensors: Proximity sensors detect the presence or absence of an object within a specified range. They are commonly used in automation, robotics, and security systems.
4. Motion Sensors: These sensors detect movement or changes in position. They are widely used in alarm systems, gaming consoles, and automatic doors.
5. Light Sensors: Light sensors measure the intensity or presence of light. They are used in applications such as automatic lighting systems, photography, and solar panels.
6. Humidity Sensors: Humidity sensors measure and monitor the moisture content in the air or in a specific environment. They are commonly used in weather monitoring, HVAC systems, and industrial processes.
7. Gas Sensors: Gas sensors detect and measure the presence of specific gases in the environment. They are used in applications such as air quality monitoring, gas leak detection, and industrial safety.
8. Accelerometers: Accelerometers measure acceleration or changes in velocity. They are widely used in motion detection, navigation systems, and electronic devices like smartphones and gaming controllers.
9. pH Sensors: pH sensors measure the acidity or alkalinity of a solution. They are commonly used in water quality monitoring, chemical analysis, and agriculture.
10. Force Sensors: Force sensors measure and detect the force or pressure applied to them. They are used in applications such as weighing scales, robotics, and industrial automation.
These are just a few examples of sensor classifications, and there are many more specialized sensors available for specific applications.
