Recently, many people are interested in the day when Chengdu will have a 5G network, but in fact, most people don't know much about the day when Chengdu will have a 5G network. Bian Xiao has compiled relevant information for everyone, hoping to bring help to everyone. 1. When will there be a 5G network in Chengdu? It will be listed as soon as 2065438+September 2009, and will be fully popularized in Chengdu in 2020. On June 6th, 20 19, the Ministry of Industry and Information Technology issued 5G commercial licenses to China Mobile, China Unicom, China Telecom and China Radio and Television. Subsequently, major operators released their respective 5G operation plans. According to the plan of China Mobile, Chengdu can use the 5G network as early as 2065438+September 2009. 2. What 5G coverage areas are there in Chengdu? Chengdu High-tech Zone and Tianfu New District have achieved 5G network coverage in important areas such as Chunxi Road Business Circle in Taikooli, High-tech South Financial Affairs Zone, Xibo City, Xinglong Lake, Metro 10 Line and Chengdu Shuangliu Airport. Third, how fast is Chengdu's 5G network experience? The most intuitive feeling of 5G is that it is fast, with a speed of 1GB/S and an average download rate of about 700 m/s. According to the test, when downloading at full speed, it only takes a few seconds to download a high-definition movie. It is worth mentioning that the 5G network has lower delay and faster buffering speed. The delay of 5G network is shortened from 50 milliseconds of 4G to 1 millisecond, and the network congestion that troubled everyone before will disappear. What is the basic concept of 4.5G network? Like the early 2G, 3G and 4G mobile networks, 5G network is a digital cellular network. In this network, the service area covered by suppliers is divided into many small geographical areas called cells. Analog signals representing sounds and images are digitized in mobile phones, converted by analog-to-digital converters and transmitted as bit streams. All the 5G wireless devices in the cell communicate with the local antenna array and low-power automatic transceiver (transmitter and receiver) in the cell through radio waves. The transceiver allocates channels from a common frequency pool that can be reused in geographically separated cells. The local antenna is connected to the telephone network and the Internet through high-bandwidth optical fiber or wireless backhaul connection. Like existing mobile phones, when users cross from one cell to another, their mobile devices will automatically "switch" to the antenna in the new cell. The main advantage of 5G network is that the data transmission rate is much higher than the previous cellular network, and the highest data transmission rate can reach 1Gbit/s, which is faster than the current wired Internet and 100 times faster than the previous 4GLTE cellular network. Another advantage is that the network delay (faster response time) is lower than 1 millisecond, while 4G is 30-70 milliseconds. Because of the faster data transmission speed, 5G network will not only provide services for mobile phones, but also become a general home and office network provider, competing with wired network providers. In the past, cellular networks provided low data rate Internet access for mobile phones, but as a general Internet provider of home computers, cellular phone towers could not provide enough bandwidth economically. Well, the above data was collected by Bian Xiao for everyone, about the day when there was a 5G network in Chengdu. I believe that everyone who has carefully read this article must have a clearer and deeper understanding of the day when Chengdu had a 5G network. I hope my answer is helpful to you! In case of doubt, legal advice is welcome. Wish you a happy life!
