The development trend positioning function of 5G cellular network
When I heard this comment at ION international technology conference last month, the comment caught my attention: "there are a lot of problems between 5G and PNT communities. I think 5G people are very important to PNT, and the PNT community missed an opportunity. "
Wifi network has provided enough convenience for people, but the development of technology has not stopped, so 5G and WiFi Internet development in the future.
World mobile news release conference, referring to the 5 g good statement has a lot of, the typical "5 g catalyst of a better future" - in the morning yesterday began to encroach on my Gmail inbox, it is like a good time for investigation. I'm not familiar with technical issues, but here's a quick summary of what's coming next in cellular communication positioning.
The data rate of 5G cellular standard is 10 gigabit per second, strong network reliability and accurate positioning accuracy. Positioning awareness is the basic requirement of many new markets, so positioning is regarded as one of the important components of 5G mobile network system design.
The honeycomb industry is in the process of implementing a long-term evolution that could be called the evolution of plain old LTE and the combination of "real 4G" mobile broadband. The demand for new mobile communication systems is increasing, and it is necessary to further enhance the network signal function, which is the fifth generation (5G) cellular network system in the future. 5G will handle communications 10 times faster than 4G, according to experts. Enough to download a 3D movie within 30 seconds of 5G network. The current 4G network will take at least six minutes.
With the development of science and technology, the development and promotion of 5G cellular mobile network will become an important development trend in the future. At present, there are also many technology manufacturers studying the technology related to 5G network. 5 g signal jammer, for example, it belongs to a kind of cell phone jammer device, now 5 g signals, however, were not popular, so its development is relatively slow some, but as the 5 g cellular network, it will surely follow.
The most popular event at the moment is the sporting event at pyeongchang, South Korea. The conference's vigilance technology expert watchers have taken note of the 5G cellular network operation. Live sled and taxiway, allowing the audience to enter the virtual driving seat, test drive this month from Seoul to pingchang, a few hours' journey, without any human intervention. These are the best examples of 5G networks. The event is an important preview of the 2020 Tokyo Olympic Games, and the 5G network will be well promoted in major cities around the world.
At the mobile world congress in Barcelona, the 5G cellular network was trumpeted, and AT&T announced that it would first launch three 5G locations, including Dallas, Texas. WACO, Texas, and Atlanta, Georgia.
Adaptive array technology has many advantages for PNT: mainly to reduce multipath and interference and shielding. Adaptive antenna arrays with digital beamforming (DBF) are increasingly important for PNT in challenging signal environments. DBF combines multiple antenna inputs to generate gain on the arrival direction of the desired satellite signal and creates space zero in the direction of interference. With the promotion of 5G, the availability of adaptive array technology will increase and the cost is expected to decline dramatically. In addition to GNSS, adaptive array technology can also be used to support short distance relative PNT applications.
In addition to the precise positioning of mobile phones provided by 5G, the two technologies also have an outstanding technology: adaptive array antennas for digital beamforming. The emerging application of DBF in 5G involves a dense microcell network, which usually covers small cell base stations in small indoor areas. The 5G cellular architecture will use adaptive array technology to achieve high data rate, spectrum reuse and communication robustness. The PNT meaning of 5G architecture is mainly about the efficient operation of the directional link, which requires a certain degree of knowledge about the user location of pico cell.
