General Bureau of Radio, Film and Television and telecommunication walk in with the attitude of cooperating for the first time.
A few days ago, ” TD-SCDMA wireless city and trade application experience exchanging meeting ” held in the department that believes worker Go, Lu XiangDong, Vice President of China Mobile, reveals, are regarded as a policy of fostering TD, the mobile phone television standard CMMB of General Bureau of Radio, Film and Television can only cooperate with TD within the next 3- 4 years, China Mobile is its only cooperative partner.
At the beginning of this year, the intersection of Engineer and letter department issued and fostered 15 measures that TD develops, among them has already involved the relevant policy of CMMB; In December of 2008, first TD CMMB cell-phones will network the releasing and establishing the foundation for the cooperation of both sides of the card.
In April of this year, General Bureau of Radio, Film and Television signs the cooperative agreement with China Mobile; May 7,of last radio Co., Ltd. call in the following text “in wide to move ” Have signed and moved the multimedia broadcast and television CMMB with China Mobile formally With the third generation of movement communication TD-SCDMA Project business cooperative agreement.
According to agreement, of both sides range of cooperation include TD cell-phone, the intersection of TD and card of surfing Internet and TD surf the Net one. Have already generally loaded CMMB function in the 2009 listing TD cell-phone, surfing the Net in future TD card of surfing Internet and TD will load CMMB module and mobile phone TV function in one.
Lu XiangDong introduces, China Mobile will be responsible for the sale of the range CMMB of China for General Bureau of Radio, Film and Television, undertake the charging function at the same time.
According to planning, up to the end of this year, 337 prefecture-level cities in China will finish CMMB network to cover, meanwhile, the network that China Mobile will finish 38 provincial capitals in China too covers, when the time comes, all ” one Liang of networks” Cover the users in the area and can all enjoy the corresponding service synchronously.
China wide to move the intersection of Vice President and TingJun Liu, say CMMB at least can offer 6 TV programme and 4 broadcast programs future, including CCTV1, CCTV3, CCTV5, CCTV news, this province and every of this city TV programme; 4 broadcast programs include the 1 every of Central People’s Broadcasting Station, China Radio International, this province and this city People’s Broadcasting Station program.
It to consumer is quite attractives to be, present CMMB serve as free. Lu XiangDong says, after July, General Bureau of Radio, Film and Television will only keep a free channel, when the time comes, China Mobile will combine TD terminal sale and charging which is responsible for China formally.
But important the intersection of chip and enterprise of CMMB create firm the intersection of video-information and relevant person, say to three, moderate breeze city that cover newly, the plan really in encrypting CMMB, but open 37 cities of CMMB in the first batch to being including Beijing, Shanghai, there is not a clear charge time table yet.
Because the mobile phone TV is one of the most representative value-added services in 3G era, so become the important market that the operator fights for. It is different to develop CMMB mode with China Mobile, 3G business that CHINAUNICOM appears on the market in the first batch has mobile phone TVs too, but as far as reporter know, what the mobile phone TV of UNICOM used is UNICOM WCDMA network.
Up till now, TD users of China Mobile have been already up to 830,000, besides mobile phone TV, 3G value-added service that China Mobile is planning also includes, realize mobile phone paying, mobile phone readers, mobile phone cartoon and moving 139 communities of Internet SNS website,etc. that SIM card combines with RFID.

On the development gradual progress of the wireless mobile communication standard, some characteristics of TD-SCDMA are being paid attention to, have adopted the technology too, and absorbed the design philosophy of some TD-SCDMA in every follow-up standards such as LTE,etc.. Duplexing technology, much location access technologies, three pieces of key technology based on that many aerial technology of MIMO/SA is TD-LTE standards based on OFDM of TDD.
TD-SCDMA the third generation of mobile communication standard that China acts on one’s own Development that gradual progress each being old for stage: First stage is from 3GPP the third generation of partner’s plan R4 standard is standard, second to R5/R6/R7 for subsequent TD-LTE TD-SCDMA gradual progress technologies subsequent stage Gradual progress standard.
Through the research, development of TD-SCDMA products, we see TD-SCDMA is because of TDD duplexing time as one Standard and technology,its technological last a lot of advantage characteristic. See, on the development gradual progress of the wireless mobile communication standard, some characteristics of TD-SCDMA are being paid attention to at the same time, have adopted the technology too, and absorbed the design philosophy of some TD-SCDMA in every follow-up standard.
TD-SCDMA has a lot of advantages
The technological characteristic of TD-SCDMA: The first is based on the duplexing technology time. The second is TD-SCDMA flexible much location way, for the management and managing and bringing convenience of resources, have offered the space for improving network performance. The third is that the intellectual aerial technology brings the advantage for respects such as network covering, interference inhibiting from, data speed,etc.. Fourth is a short code CDMA code division multiple access With the low yard of speed, and complete time slot structure. The fifth is empty mouthfuls of course optimized, one layer of application that has actually drawn lessons from TD-SCDMA of physics in TD-LTE. The sixth is the synchronous mechanism of the system, TD-SCDMA technology is to need the system to be synchronous, the assessment to LTE-FDD performance, also set up and pay analyzing on the basis of moving ahead simultaneously.
The mobile communication system has the three basic characteristics: First, the dynamic characteristic of the channel; Second, the mobile subscriber’s dynamic characteristic; Third, the dynamic characteristic of the mobile communication business. Three major dynamic characteristics of mobile communication, in fact has determined us to systematic research, course of standard gradual progress development of mobile communication too.
Datang move, consider development and the intersection of gradual progress and question, pairs of TD-LTE, IMT-Advanced senior international mobile communication on the basis of TD-SCDMA TDD orientates as the gradual progress edition of TD-SCDMA, extends and develops the achievement of China in the field of 3G.
TD-LTE three major key technology
There are several pieces of key technology in TD-LTE: The first is the duplexing technology based on TDD. Inside TDD way, the duplexing way switched over in TDD time is the duplexing course of defining it in a frame structure.
Consider FDD divide while discussing TDD system frequently duplexingly The system, in TDD/FDD bimodulus, LTE norm offered the commonality of technology and standard. We will notice the basic difference between TDD and FDD. Different to spectral demands at first, it is different to receive and dispatch the working way of the radio frequency. TDD apparatus needs to carry on the frequent change-over switch of receiving and dispatching, FDD needs to isolate and send and receive the duplexing wave filter of the passway; It is a time interval that TDD mode is distributed, it is a frequency band that FDD mode is distributed. Secondly, TDD and upper and lower competent channel of FDD symmetry different, the intersection of P2P and reciprocal network technique in the future Will feel this difference while employing obviously. Finally, two kinds of systematic ones demand synchronously to be different. Compared with difference of FDD system, make us need to consider wholly when the key parameter of the system is designed in the future through TDD.
Second key technology is OFDM perpendicularity divides and replies and uses technology frequently . Among them there are two keys, first, OFDM technology and MIMO input and export more more How to combine technology, make the systematic function of mobile communication further promote; Second, OFDM technology is under the terms of group’s network of mobile communication of the honeycomb, how to overcome and organize the question that the network brings frequently.
OFDM has one’s own advantages, for example it is multipath to resist and propagate and the alternative decline ability of frequency is strong, dynamic channel assign technology make system reach most large transfer rate, resist ability better than single signal carrier system to whom pulse interfere with, spectral efficiency is higher than the serial system.
The interference question in the Residential Area in OFDM, in order to have wireless inserting, wired maturity technology that inserts now, the interference in the Residential Area can be dispelled or avoided more easily.
The third is many aerial technology based on MIMO/SA. Intellectual aerial technology is through composing the shape, offer and cover and coordinate the technology of ability with the interference. MIMO technology offered different transmission ability through many aerials, the ones that offered the space to reply and use were gained, these two kinds of technology are very important technology in the subsequent gradual progress systems of LTE and LTE. We pay close attention to MIMO technology and combination on the subsequent gradual progress of intellectual aerial technology very much at the same time.
Adopt many aerial technology, on one hand performance needs, on the other hand it is a need of the follow-up standard gradual progress. Many aerial technology proposes some indexes, can offer the space to reply and use and transmits and grade in many aerials are used.
The dispositions of many aerials in LTE, falling can support the sending of single antenna, two aerials, four aerials, support the application of the intellectual aerial at the same time, can be with over four aerials, such as the application of eight aerials. It is that a single antenna is sent to upgo, do not get rid of application of many aerials in follow-up. In the standardized course that many aerials employ inside LTE, through many kinds of efforts, in last April, 3GPP standard organization accept intellectual the intersection of application and as TDD mode characteristic one of of aerial finally.
3GPP has already started LTE-Advanced project at present, need to support higher peak value speed, higher spectral efficiency, and higher user’s throughput and user’s number, also need further improving the experience of the edge users of Residential Area.
Raising one’s head and looking and substituting X25-M solid condition hard disk with third of Intel that wishes will release soon, Intel is called ” Postville Refresh ” the research and development coaxiality of X25- M G2 ,He has inherited the appearance of X25-M series products since 2008. Adopt IMFT flashing memory chip of 25 nanometers of craft processes, this means realizing the memory capacity of turning over time at same price. Though Intel 25 the intersection of MLC NAND and flashing memory kind produces, seen SSD driver yet so far. It is said before producing NAND in batches, there are a lot relevant process craft of 25 nanometers to need adjusting. The third generation driver would emerge in the first quarter of 2011, all serial capacity are from 40GB X25-V To 600GB.
Third generation SSD driver specification index of revealed secrets
Though Intel calls listing X25 – M new to only support SATA 3Gbps standard, its internal SATA norm staging reaches ATA8-ACS of standing, perhaps after Intel chip set offer primary SATA 6Gbps to support, SATA 6Gbps official side that Intel will open the own solid condition hard disk supports.
Characteristics and specifications of the new drivers are all greatly improved. The comparison between the two is as follows:
If accurate parameter these, X25-M G3 should in the same horizon by beautiful mere Crucial RealSSD C300 or SandForce SF-1200 scheme. Certainly will also a lot of different routes will be tested, so the test data float. Please note, because is still carrying on much adjustment at present, the characteristic may be known and improved when it emerges. Have to say that looks at the present characteristic level, the pricing of Intel can preferably have advantages even more, because I drive and full of more expectation SandForce of future generation.
