” the whole world moves the flow of the broadband data to increase by 500 times in the following 10 years ” ,You perhaps will suspect one’s own ears to hear this information. But increase with moving the explosion type of the abundant day by day and intelligent terminal of the intersection of Internet and the intersection of business and kind, the application which moves broadband will be broader and broader, increase by 500 times and does not overstate in 10.
Wireless communication progresses fast because of moving the high bandwidth demand of business too, already progressively ripe LTE LongTermEvolution at present Technology can offer and is higher than 3G speed by dozens of times, shorter wireless business of prolonging is experienced when continuing, realize that / falling exceeds 50Mbit / second and 100Mbit / second’s transfer rate and better carrying to the quality guarantee of end separately. According to GSA ‘ The whole world moves supplier’s association The latest report of official side released a few days ago, 218 operators of 81 countries in the world were investing in the construction of LTE network including FDD and TDD two rules ,Present growth trend by a wide margin more than 98 in 2010. Up to the end of 2011, it is estimated 91 LTE networks will put into commercially. LTE terminal station increases correspondingly fast too, rises to 161 style of July of 2011 from only a fund at the end of 2009.
We can see, the globalized development of LTE has already been the trend of the times. Every telecommunication apparatus trader of the industry, include Ericsson, China catch the network technique and update this great opportunity for the intersection of Alcatel and Lucent, the intersection of Nokia and Siemens and resurgence,etc. one after another, accelerate technological innovation paces, improve the ability of market exploring, make every effort to occupy one’s own one seat at LTE age. Distributed to see from LTE key patent owning amount and market at present, have traditional Ericsson, China of advantage can still occupy the leading status for the intersection of Nokia and the intersection of Siemens,etc. and major producer too at LTE age in 2G/3G. Reveal datas newest of ISOInternational Standards Organization 3GPP whether since 2010,China for LTE patents standards key count to exceed 230 items, rank the industry first, it is thereafter producers such as Ericsson, Alcatel Lucent, Nokia Siemens, Samsung and high pass,etc. sequentially. According to LTE progress report that GSA released, the whole world has been already in 35 commercial LTE networks formally a commercial network may have been disposed by many manufacturers ,China is and Ericsson has obvious advantages, 18 LTE commercial networks among them, by China in order to dispose, 15 are disposed by Ericsson; Nokia Siemens demonstrates more powerful competitiveness too, has disposed 11 commercial networks. In addition there is commercial arrangement of small quantity in Alcatel Lucent and resurgence, though the quantity does not preponderate, but enthusiasm and efforts of investing LTE of two producers were not weakened: The intersection of Alcatel and Lucent main contractor for the construction one of, VerisonFDD-LTE of U.S.A., ‘ Another contractor for the construction is Ericsson ; The up-and-coming youngster’s resurgence has been thinking all the time the future LTE market is the moment of the real creation miracle, and reveal ” on the future income from sales of network equipment ” to the media many times, third in the world of goal ” Ambition,shorten with Ericsson and China to disparity, last Nokia the pursuits of the Siemenses it stop.
A famous saying spreads in the circle of communicating at present: ” it has the future that is there frequency spectrum ” ,With the arrival of the digital flood, the operator pays more and more attention to the development of MBB, frequency spectrum will become the resources that have key competitiveness most, TD-LTE technology of the high spectral utilization ratio solves the limited problem of spectral resource effectively, will become the best choice of operator. Until the intersection of video and business popularize, TDD from head to foot competent to dispose bandwidth while being flexible, share spectral advantage, invent apparent, can meet MBB better era bear the weight of according to the intersection of business and upper and lower competent the intersection of asymmetry and characteristic and the intersection of trade and diversified business of market. In addition, operators on the major market such as China, Japan and North America generally adopt frequency spectrum of TDD large bandwidth, can realize dilatation of many signal carriers very conveniently. So, the industry generally keep an eye on the newcoming advantage of TD-LTE.
In China, since undertaking the construction of TD-SCDMA network in China Mobile, actively promotes TD users to distribute telephone numbers to promote the utilization ratio of the network to promote on one hand, consider actively TD network launches LTE now under the direction of engineering letter one the network proves to the smooth gradual progress of subsequent TD-LTEs at the same time. By September of 2011, six major cities of Shanghai, Nanjing, Hangzhou, Guangzhou, Shenzhen, Xiamen finished testing at the first stages of one hundred stations of cities of TD-LTE, include Ericsson, China participate in 7 apparatus traders inside for, Nokia Siemens and resurgence, finish the intersection of LTE and the intersection of group and the intersection of network and function, performance and end reach the intersection of end and scheme,etc. prove second stage 9 city expand scale, test and start conceptual design at present.
More notice at the same time we,is it in the world a lot of TD-LTE construction pace of operator let’s walk already in in front of China Mobile. By the end of November of 2011, have already signed 14 TD-LTE commercial contracts soft silver and Saudi Arabian Mobily of Japan among them have already released commercially in the whole world . Because Chinese producer researches and develops the progress and takes the first chance comparatively fast, for outshine others, obtain among them 10 contract including exclusive the intersection of Polish and Aero2, the intersection of Saudi Arabian and Mobily and the intersection of Danish and the intersection of Hi3G,etc. and 7 networks of construction China, and undertake the construction of Tokyo, Osaka, Nagoya of soft silver of Japan,etc. network of key district ,Signed the contracts of areas such as Swedish H3G and Japanese soft silver Hokkaido, Fukuoka,etc. in 2010 in resurgence. Ericsson and Nokia Siemens that has deep accumulation in the field of FDD begins to pay attention to TD-LTE field this year, and have an effect continuously: Ericsson sign two commercial to cooperate in TD-LTE with the intersection of Indian and Augere and the intersection of Australia and NBN successively, Nokia Siemens has obtained Brazilian Sky-TV exclusive TD-LTE and built the qualification, this causes resurgence not to reap the new TD-LTE commercial contract yet from the year 2011 till now to a certain extent too. It is the biggest TD-LTE commercial network in the world in the soft silver TD-LTE network of Japan of construction at present, especially key area such as Tokyo, Osaka, Nagoya, the number of LTE website is density over 30 / Km2 require 100 / Km2 in the future ,So extremely dense urban group’s network, bandwidth of base station, power ability to the apparatus producer, and double-current BF The beam is composed and appeared , the maturity in technology such as MIMO proposes being called the harsh challenge. Can be expected, construction and operation of this key area can offer the valuable reference experience for the fact that the subsequent intensive urban area of megalopolis of China is built and run.
Can believe, as the operator realizes the flexibility advantage that TDD rule utilizes in the frequency progressively, constant completion of the industry chain such as being absorbed and terminal of and the major apparatus producer continuously in the field of TDD, TD-LTE will get more extensive popularization and application in the world, will become the future by mainly bearing the weight of technology of hundredfold data business that increases rapidly.
