According to Feng Jiahui, senior associate at Ericsson Taiwan, Hong Kong and Macau, a non-independent architecture standard to be finalized by the end of the year, users have used 4G technology when using network services in the past when VoLTE had not been widely popularized. However, When it comes to call service, the communication service will be automatically dropped to 3G, and after VoLTE is gradually popularized, it will be possible to use 4G technology for both the network and the call service at the same time. When the NSA standard enters commercial service, a similar architecture may be adopted, Since 5G uses many high-frequency spectrums to limit its network coverage, telecom operators' 5G networks should initially only cover small areas. When users leave the coverage area of 5G signals, they will need to close the 4G network , In order to achieve the goal of continuous network.
In the application section, Fung Ka Fai believes that although the company is very optimistic about the 5G in various fields, the development potential of the industry, but when the 5G business has just begun, the main revenue of communications services will inevitably be based on smart phones, such as 8K video However, due to the rapid development of automobile autopilot technology, the future of the car is likely to be followed by smart phones, another large-scale networked terminal device.At present, cars The immediacy of networking is not yet very strong, but in the age of self-driving, internet communication is needed between cars and cars, cars and pedestrians, cars and public facilities, and the response speed must be fast before they can be helped Solve various traffic problems and may even reduce the possibility of accidents caused by improper driving.
Feng Jiahui pointed out that for this car networking needs, in addition to 5G running on licensed spectrum obtained by the telecom operators, other unlicensed spectrum communication technology, due to the use of too many people, to achieve high reliability of communication there will be very With this in mind, 5G will be a key communications technology for applications like autopilot.
However, at present, not all cars have not yet used networking technology. For example, Telia, a Swedish telecommunications operator, has already installed a SIM card near the car seat to realize car Wi-Fi, which enables all car occupants Can use the Wi-Fi to access the Internet service.At the same time, Telia also cooperate with the insurance company to help them get the driver's car status immediately, as a basis for judging how to adjust the owner's premium in the future.
Feng Jiahui believes that this cooperation model with the insurance company is very important, because without such a cooperation model, simply provide only Wi-Fi service, the value brought about is obviously lower. Coupled with the depot Given the established business model, it is unlikely that the carriers' SIM cards will be installed automatically in their vehicles, so it is necessary for telecom operators to build more partners in order for the value of their network communications to be fully realized.
