I believe everyone wants to know, what is 5G? How fast is 5G technology? Why do you have the experience of the future “super-interconnected” era? Today, we will take you to 5G common sense, and learn to steal it!
1. What is 5G?
First of all, what is 5G? Simply put, 5G is the fifth generation of communication technology.
Three major features of 5G: large bandwidth, low latency, and all things connected.
The main features of 5G: the wavelength is millimeter.
2. How fast is 5G?
American chipmaker Qualcomm believes that 5G can achieve 10 to 20 times faster browsing and download speeds under actual (rather than laboratory) conditions. In other words, you can download a high-definition movie in about 1 minute.
And we are talking about the 5G network built on the existing 4G LTE network, just the first generation 5G modem; the future 5G chip is likely to be faster.
Independent 5G networks can operate at very high frequencies (such as 30 GHz), making it easy to achieve gigabit or higher browsing speeds. However, this scenario is unlikely to occur within a few years.
3. 5G faster than 4G
At present, the fastest 4G mobile network provides a network speed of about 45Mbps (megabits per second), compared to 5G.
The 5G transmission rate will be 1Gb/s, which is more than ten times faster than the current 4G. This means that downloading a 1GB HD movie using 5G technology takes only 10 seconds to complete, and a “Blade King” trilogy with a longer Blu-ray of more than 70 GB is about 1 minute.
5G’s large bandwidth transmission capability, even if you look at 4K HD video, 360-degree panoramic video and VR virtual reality experience, there will be no Karton situation.
4. 5G can dry up
So, what can 5G do? Speaking out will really scare you.
5G will bring fiber-like “zero” delay access rate, and will increase the energy efficiency of the network by a hundred times, reduce the bit cost by a hundred times, and narrow the distance between people and all things, and finally achieve “all things can be reached and in fact, in addition to the above, 5G can bring, and more are new business that we can’t predict. For example, 5G will bring more high-definition video and higher energy efficiency to driverless cars, augmented reality AR/virtual reality VR, drone work group, etc., and make the city more intelligent Internet of Things.
In general, if you are a gamer, then with 5G, the delay between pressing the controller button and displaying the effect on the screen will be shorter. Video playback on mobile devices is faster and more stable. Video chat quality will be clearer and smoother.
5. 5G radiation is big?
First of all, it can be affirmed that under the daily life scene, the 5G mobile phonewill not increase the radiation of the body. Mobile phone manufacturers must go through various rigorous audits and tests before they can list new mobile phones. They need to meet relevant national standards before they can go public.
The 5G frequency band requires high base stations to be denser, so the radiation is large. This understanding is misunderstood. On the contrary, the radiation from 2G to 3G to the 4G base station is getting smaller and smaller. In the 2G era, a base station is tens of kilometers in a circle, and a base station is a few hundred meters in a 4G radius. The number of base stations in the 5G era is more. Due to the power control, the denser the base station, the smaller the radiation.
6. 5G key wireless technology
So, what are the key wireless technologies for 5G? This involves professional knowledge, let us know.
5G key wireless technologies: large-scale antenna, ultra-dense networking, flexible duplex, full-duplex, spectrum sharing, advanced modulation and coding, terminal straight-through technology, full spectrum access, new multi-access, and new multi-carrier.
SDR: Universal hardware + software upgradeable.
MIMO: multi-antenna transmission, multi-antenna reception + boost channel capacity.
CCFD: Simultaneously transmit and receive electromagnetic wave signals at the same frequency to improve spectrum efficiency.
OFDM: Orthogonal Frequency Division Multiplexing.
7. how much is 5G mobile phone?
Since 5G mobile phones support more modes, standards, and frequency points than 4G mobile phones, new technologies such as “millimeter wave” and “MIMO multi-antenna”, chips, structural components, and RF components will all bring about an increase in hardware costs.
The 5G mobile phones listed on the market will be placed on the high-end models, and the price is expected to be more than 700 dollar. Looking back at the price of 4G mobile phones, almost all the way down, the current fifty dollor mobile has fully supported 4G. In the 1-2 years after 5G commercial use, the number of models will increase rapidly, and the price of 5G mobile phones will also become lower.
8. 5G arrived
Most countries are unlikely to launch 5G services by 2020, but Qatar’s Ooredoo said it has launched commercial services, while South Korea plans to start next year, and South Korea’s three largest network operators agree to start serving at the same time. China is also striving to launch 5G services in 2019.
At the same time, regulators around the world have been busy auctioning spectrum to telecommunications companies that have been experimenting with the new business with handset manufacturers.
