3. Apple's 5G mobile phone
iPhone 12 Pro Max, iPhone 12 Pro, iPhone 12, iPhone 12 mini.
4. ZTE
ZTE Axon1Pro 5G is another domestic first-to-market 5G mobile phone. Based on Qualcomm Snapdragon 855+ processor, it supports 5G network by plug-in X5 5G baseband. The supported 5G network architecture is NSA, which is a non-independent networking mode.
5. Samsung
Samsung Note1+ 5G is Samsung's latest 5G flagship mobile phone for the world. Like ZTE Axon1Pro 5G, Samsung Note1+ 5G relies on Snapdragon X5 external baseband to support 5G network. Samsung S1 5G version, although Samsung S1 on the market is equipped with Qualcomm Snapdragon 855 processor, but the key 5G baseband X5 or the latest X55 is not matched with it. If you need to use 5G network, you can only wait until the 5G version of S1 is updated.
6.OPPO
OPPO, Yijia, Nubia and other manufacturers have announced the prototype of 5G, which has realized the access to the 5G network, but there is still a period of time before mass production is brought to market.
5G standard:
on December 21st, 217, at the 78th plenary meeting of 3GPP RAN, an international telecommunication standard organization, the first release version of 5G NR was officially released, which will be the first commercially deployable 5G standard in the world. Among them, China Mobile Communications Group Co., Ltd., as the reporter and chief editor of the protocol, led the completion of the research project of 5G air interface scenarios and requirements, and exported the programmatic document of 5G air interface technology, which was taken as the criterion for all subsequent technology research and development and standardization.
5G network:
The biggest difference between 5G mobile phones and other mobile phones is that they support 5G networks. Of course, the premise is that there is a 5G network, and the three major operators need to build the network first. Mobile phones supporting 5G networks naturally have the advantages of 5G networks. Like the early 2G, 3G and 4G mobile networks, the 5G mobile 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 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. Transceivers allocate channels from a common frequency pool, which 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.
Main advantages:
The main advantage of p>5G network is that the data transmission rate is much higher than that of the previous cellular network, with the highest rate of 1Gbit/s, which is faster than the current wired Internet and 1 times faster than the previous 4G LTE cellular network. Another advantage is lower network delay (faster response time), less than 1 millisecond, while 4G is 3-7 milliseconds. Because of the faster data transmission, 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. Previous cellular networks provided low data rate Internet access for mobile phones, but a cell phone tower could not provide enough bandwidth economically as a general Internet provider for home computers.
network characteristics
the peak rate needs to meet the Gbit/s standard, so as to meet the high-definition video, virtual reality and other large data transmission.
the air interface delay level needs to be about 1ms, which can meet the real-time applications such as automatic driving and telemedicine.
super-large network capacity, providing the connection capability of hundreds of billions of devices to meet the communication of Internet of Things.
the spectrum efficiency is more than 1 times higher than that of LTE.
with continuous wide-area coverage and high mobility, the user experience rate reaches 1 mbit/s.
traffic density and connection density have been greatly improved.
the system is collaborative, and the level of intelligence is improved, which is characterized by multi-user, multi-point, multi-antenna, multi-intake collaborative networking and flexible automatic adjustment between networks.
the above is the key that distinguishes 5G from previous generations of mobile communication, and it is the result of the gradual transformation of mobile communication from technology-centric to user-centric.
