In today's CES Symposium - 'Mobile Innovation: How 5G Will Support the Future,' we explain why, and while the 5G standard has been approved and has undergone a series of successful tests, and by 2018 the four major U.S. carriers Two of them plan to deploy it, but the related hardware is not yet ready, but this situation will change soon, let's take a look at the 5G put into practical application.
What is 5G in the end?
Increasing the speed of current data connections by 10 to 100 times, reducing response delays to 'unobtrusive', increasing security, and essentially increasing the size of each network are all given by the 5th generation cellular network technology (5G) Promise of.
With higher bandwidth radio signals, multiple antennas working together and faster processor support, the 5G is expected to blur the line between wired broadband and wireless connectivity earlier this week at Samsung's CES press conference, Its executive Tim Baxter said the 5G 'inserts fiber-optic cables into their pockets, "although the 5G range is far greater than pocket devices.
5G in the end how much impact?
If you believe in AT & T, Qualcomm, Samsung, T-Mobile and Verizon, the 5G wireless network will affect almost everything, including devices and industries that were previously tapped only by cellphone services. At the CES seminar, Qualcomm implemented Vice President Cristiano Amon said: 'On a 5G basis, everything is wireless, it's not just mobile, it's basically ubiquitous.' 'Verizon executive Hans Vestberg ) Also said that 5G will change industry and society, which is the most important.But how it changes:
High bandwidth: 5G will replace the broadband cable service, enabling streaming media support 4K VR / AR or even 8K video
Low latency: will enable unmanned vehicles to constantly coordinate with the transportation system and other vehicles
Safety: From the start, it is guaranteed that the vehicle can not be taken over and weaponized
Larger networks: There is enough free capacity to host millions of IoT devices, including low-bandwidth devices that intermittently connect to the Internet
Larger Scale: Large-scale public and private spaces, including entire cities, hospitals and manufacturing facilities, will be remotely accessible online, such as cameras, computer systems and small devices in these spaces, 5G intentions and designs initially Is commercialized and such an automated business can use 5G remote management
Predict these things is easy, but they really happen?
The seminar attendees suggested that 5G technology is likely to be much faster than 4G technology given that many people are now connected and required to provide services. In addition, 5G has great potential to change society. In the CES seminar, Qualcomm Amon said that 4G smartphones have helped to change the banking industry: Today, average users have more banking applications than the physical department, and the speed, reach and scale of 5G services will make people expect more.
Lu Yi, Baidu's CTO, explained at CES that the impact of the 5G video will be enormous and over time will "replace a lot of written language exchange." He also predicts that Dialog AI, driverless cars and the future Infrastructure for public-private partnerships in the city will all get 5G of help.
What is fixed 5G and mobile 5G?
Fixed 5G refers to 5G services that are used in homes, businesses, or schools alone, and mobile 5G refers to networks that move as you travel outdoors or in various forms of transportation. T-Mobile claims that AT & T and Verizon are primarily focused While providing fixed 5G technology instead of moving 5G, the former may be easier to achieve, while the latter faces many unique technical hurdles.
AT & T seems to be dismissing the claim and saying it will begin shipping Mobile 5G in 12 markets by late 2018. In this panel discussion, Verizon's Vestas appears to confirm T-Mobile's suspicion and points out Verizon plans to roll out its 5G program in three to five markets by 2018, focusing on residential broadband using pre-standard 5G hardware so it can grow confident about its 5G technology and network, which VW says: "Although Small, but Verizon will take the lead and this is the most important. '
What are the key 5G technologies?
Here's what you need to know to bring 5G technology to life requires new technologies and major updates to existing technologies:
Radio waves and radio equipment
If you've ever heard of 'cellular radios' on your cellphone, it's because cellular technology relies on transmitting and receiving radio waves. The more information you get from' cells' or 'cell towers,' your cell phone ' Cell tower communications consume more power just as 4G or LTE replace 3G and 3G replace 2G or EDGE, operators need to install new 5G radio hardware on the towers to support new devices that receive and send data.
On the broadcast side, Qualcomm offers a 'tunable' radio solution that can be tuned to thousands of possible frequencies, either broadband or narrowband, to accommodate 4G to 5G conversion, while devices also require new wireless chips And the antenna.
Millimeter wave broadcast
You may have heard of millimeter waves in airport security areas and may be further concerned about their radiation effects because they provide 5G wireless service anywhere.They are separate technologies that show that millimeter waves have no effect on organic matter and are said to be The same is true for radio waves, which are chosen for 5G because they are particularly good at carrying large amounts of data and can transmit data over very long distances with very little energy. In addition, millimeter-wave bands are used around the world All are open.
However, these waves are not good at penetrating buildings and often require 'line of sight' to connect their broadcast and reception points. They can be scattered by objects and even rain, although Verhon's Von Hoearth said that the millimeter Wave transmission test 'proved to be much better than we thought.' However, 5G suppliers need ...
Multi-frequency support
Low frequency, medium frequency and high frequency radio waves will be used to distribute 5G data, of which low frequency (600mHz) can easily penetrate buildings and provide some bandwidth improvement in mid-frequency (1900mHz) and high frequency 60000mHz) can not penetrate buildings or objects, but can work long distances. Medium frequency waves are currently used in mobile devices, and in extreme cases compromise.
T-Mobile has been buying low-frequency spectrum throughout the United States and promised to use it for 5-g coast-to-shore communications, but the company acknowledged that the 5G may require low, medium and high frequency radio spectrum.In the panel discussion, Qualcomm Amon also mentions the same thing, saying there will be 5 bands in the 'bands',' bands' 6 and the middle 'reused existing bands.' Armon said: '5G is not alone Millimeter-wave or low-frequency selection, which is related to all wave frequency and spectrum, a gigabit LTE foundation covering more dense millimeter waves, Gigabit, all of which are unified.
5G face the restrictions
As US carriers are eager to plug their 5G banner across the United States, the hardware is not ready, and as Qualcomm pointed out, 40 companies have come together to accelerate the standardization of 5G and 'the most important Christmas gift is the A 5G standard 3GPP is approved. "But in spite of this, there is no final chip or device yet.
Amon said he hopes to show 'a 5G cell phone powered by Snapdragon processors' at CES next year, indicating that Qualcomm is not expected to introduce a mobile 5G product by 2018.
Today, companies can prototype devices with prototyping chips and antennas to test the prototype network, but chips and antennas are not available until the 5G standard is complete. Actual products may not be released in the near future unless a large number of related products are available. Different products, from development to release cycle usually takes one to two years.
Testing of fixed 5G and mobile 5G products has been going on for some time, and Baidu Lu Yi said most of the work and testing in the United States will spread to China and the rest of the world by 2018. The U.S. carriers will largely 2018 Considered the year leading to the '5G Road', where 'bridge technology' faster LTE advanced data and huge MIMO antenna arrays will be deployed before 5G arrives Verizon's Vital Technology said 2018 will be 5G ecosystem to develop and test the product, and integrate it into the year.
It is worth noting that although South Korea has been actively deploying 4G networks, it has not yet started the deployment of 5G, and the European plan will not be announced at the earliest next month at the Mobile World Congress in Barcelona .
5G when will really come?
Although AT & T announced at a press briefing prior to the CES opening that 12 mobile 5G deployments will be available by the end of 2018, Verizon also promised to launch its first fixed 5G deployment prior to AT & T, but panelists seem to believe that 5G May 2019 or 2020 to large-scale promotion.
Amon, a Qualcomm company, said that "flagship smartphones" may be on shelves as early as the beginning of 2019 and the first consumers will begin the transition to 5G, so in a sense, T-Mobile is expected to deliver 5G by 2020 Full deployment and deployment in 2019. In other words, keeping a close eye on CES in 2019 should be a real opportunity for the 5G, and the main task for this year is to lay the groundwork for that.
