One of the most important focuses of MWC2017 is undoubtedly 5G technology. This technology may not have to wait until 2020. At present, operators, chip companies and communication equipment companies are actively participating in the competition. They may promote this technology to be commercialized in the next two years. .
Operators are eager to pushUS operator Verizon announced that it will provide 5G services in 11 cities in the United States this year. It is so eager to launch because of the sweet taste when it comes to 4G commercial use.
At that time, 3G technology HSPA had the early speed with LTE, so AT&T operating HSPA was not eager to launch LTE network, and Verizon's CDMA2000 technology could not be compared with HSPA. In desperation, Verizon took the lead in setting up LTE network to deal with AT&T competition. As a result, AT&T quickly discovered that its HSPA technology could not compete with LTE, and announced its opening of its LTE network a year later.
Several major operators in China are now experiencing similar competition. China Mobile has a first-mover advantage in the 4G era. Its TD-LTE network precedes the one-year construction of China Telecom and China Unicom's LTE-FDD, and with its capital advantage, it has built a coverage rate close to GSM in one year. The 4G network, as of 2016, the number of 4G users of the three operators is 535 million, 122 million, 104.6 million, China Mobile is leading by absolute advantage.
In order to change this competitive disadvantage, China Telecom is actively promoting the testing of 5G networks. As early as April, China Telecom Jiangsu will deploy more than 600 5G base stations in its service area.
Although China Mobile has a leading network coverage advantage for 4G networks, TD-LTE technology is not as good as Unicom and Telecom's LTE-FDD, so it is also rapidly advancing 5G network testing. This year, 4 to 5 cities will be selected in each city. Seven sites were built for system verification, but I am afraid that this progress will be accelerated by China Telecom.
Competition of telecommunications equipment vendorsEricsson used to be the world's largest telecommunications equipment supplier. However, after being defeated by Huawei, the performance in these years has not been very good. It is putting hope on 5G, and hopes to promote the development of 5G to find space for development. It has 5G technology advantages. .
Ericsson is the leader of the European 5G standard and is striving to promote LTE-FDD to 5G to ensure that its 5G standard has a dominant advantage. At the same time, Cisco, which is aligned with it, is also challenged by Huawei. Both hope to suppress Huawei's. The challenge, of course, hopes to promote the development of 5G.
As the largest telecom equipment supplier, Huawei is not willing to lag behind. It also hopes to become one of the leaders in the 5G standard and realize the transformation from technology followers to leaders.
Last year, its main Polar Code solution became the 5G control channel eMBB scenario (uplink/downlink) coding scheme. This is the embodiment. With the largest market in China, if you can commercialize 5G first, you will be able to obtain more 5G patents in practice. In the past few years, it has also been actively working with China's largest operator, China Mobile Commercial 4G+ to verify part of the 5G technology.
Samsung is the world's largest mobile phone company and a leading chip company. In addition, it cannot be ignored that it is actively entering the field of telecommunications equipment.
In the 4G standard, data from Taiwan's "National Research Institute" and ETSI statistics show that Samsung has a large number of 4G patents, and Qualcomm and Huawei rank among the top three 4G core patents worldwide. Leading the way in the development of baseband technology, Samsung is one of the three chip companies in the world to support 1Gbps. The other two are Qualcomm and Intel. Huawei, the largest telecom equipment vendor, has not yet launched a baseband supporting 1Gbps.
On the 24th of this month, British communications company Arqiva and Samsung Electronics jointly announced that they will try to operate the UK's first 5G network in London this year, which will use Samsung's 5G base station and equipment, which means Samsung has officially entered the field of telecommunications equipment. , competing with Huawei, Ericsson, etc.
Chip company competitionQualcomm is undoubtedly the leader in the development of baseband chips for 5G technology. It is the first to introduce a baseband supporting 1Gbps. Recently, it has introduced a baseband supporting 1.2Gbps, and has released the X50 supporting 5G technology, which can support up to 5Gbps downlink.
Since the 3G era, Qualcomm has been threatened by China's Taiwanese chip company MediaTek. Before 2014, 4G commercial is the main 4G chip supplier. After China began commercial 4G in 2014, it only had Qualcomm for half a year. And Marvell provided 4G chips, and MediaTek and Huawei HiSilith introduced mobile phone chips supporting 4G technology until the same year.
Today, MediaTek's upcoming helio X30 only supports 600Mbps downlink. Qualcomm certainly hopes that 5G will continue to become the dominant player in the mobile phone chip market with its technological advantages.
Intel has not made progress in the mobile market in the past few years. Until last year, Apple began to introduce Intel's baseband on the iPhone7. This year, Intel's XVM7560-based support for 1Gbps is expected to continue to be used by Apple. Intel is hoping for the Internet of Things era in the 5G era, and hopes to make breakthroughs in the field of ICT integration by virtue of its advantages in the server market, and of course actively promote the development of 5G.
In addition to its success in the telecom equipment market, Samsung is also actively deploying on the chip. In addition to the upcoming release of Exynos9 supporting 1Gbps, it recently announced that its 5G RF chip (Radio Frequency Integrated Circuit, RFIC) is commercially ready. And announced that it will launch a commercial solution next year.
In summary, with the active promotion of all parties, 5G commercials should not wait until 2020. The 2018 South Korea Pyeongchang Winter Olympics will use 5G mobile communication technology for the first time. I believe other operators will follow up quickly.
