China Mobile launches bidding for 4G equipment bid for LTE network design

On June 20, China Mobile launched a bidding for TD-LTE wireless network survey and design involving 170,000 base stations, which opened the prelude to its bidding for over 4 billion yuan of 4G equipment this year.

"China Mobile is going to 4G, and this year, this is basically a thing." A person from the equipment manufacturer told reporters that the equipment standard for equipment manufacturers has not been finalized due to differences in network construction paths. In the first place, the survey bid can save time for the entire network construction process to a certain extent, "first make the smaller part of the uncertainties".

Survey and design is an important part of engineering construction. The equipment supplier said that although there is no strict sequence relationship between the survey design and equipment bids from the bidding process, "whichever is first to start", but in the case of equipment bids dragging and dragging, this time 170,000 The launch of the base station survey bidding, on the one hand, means that the entire network construction has begun to be put on the agenda, on the other hand, it also hints from the side that China Mobile's internal differences in equipment bidding.

Multiple networking solutions

According to the announcement issued by China Mobile Procurement and Tendering Network on June 20, this tender called "2013 Centralized Procurement of TD-LTE Wireless Network Survey and Design Services", with a scale of 170,000 base stations, requires 28 bidders in the country Provinces, cities, and autonomous regions (excluding Beijing, Guangdong, and Inner Mongolia) provide survey and design services. Each province is divided into 1 independent standard package, for a total of 28 standard packages. The time for the bidder to purchase the bidding documents is June 24-28.

"Beijing, Guangdong and Inner Mongolia are not included in the scope of this survey bid. It may be that the survey and design of these places already have suitable suppliers or have other arrangements." The above equipment vendors believe that the survey of 170,000 base stations The target scale, plus Beijing, Guangdong and Inner Mongolia, the total scale is roughly the same as China Mobile's previously clear 200,000 base station TD-LTE network construction scale this year.

Survey and design bidding is different from equipment bidding. The former is for communication design companies and the latter is for equipment suppliers. According to the information previously shown in multiple channels, within this year, China Mobile's new phase of TD-LTE bidding will build 200,000 base stations, covering more than 100 cities across the country, and involving equipment bids exceeding 20 billion yuan. However, the original 4G bidding that the industry expected to launch in April this year has not yet been officially launched. On June 20, a number of communication equipment vendors all told reporters that they still have not received information on the bidding initiation from China Mobile.

"China Mobile has not yet formed a unified opinion on the network construction plan, and we can only wait." A person from the equipment supplier told reporters that the bidding for the 200,000 base stations that the equipment supplier wanted to see was delayed on the agenda because China Mobile Internally, there are still different opinions on whether to build or upgrade.

At present, the frequency bands available for China Mobile's network construction are at least the F-band and the D-band. Among them, the D-band is the global mainstream TD-LTE band determined by the International Telecommunication Union. The Ministry of Industry and Information Technology of China has also clarified that the total frequency of this band is 190MHz (2500-2690MHz). For TD-LTE. F-band is the main frequency band of China Mobile's TD-SCDMA.

In this way, China Mobile's 4G network construction has F-band, D-band, and F / D hybrid networking and other solutions, and F-band has two solutions based on the original TD-SCDMA base station upgrade and co-site new construction. In the face of their choices, not only China Mobile's internal disputes, but equipment vendors based on different interests have also been divided into different camps.

Among them, Ericsson believes that from the perspective of technical indicators and long-term benefits of operators, the new construction plan is more ideal. The reason is that the location of the F-band is complicated, including both PHS and TD-SCDMA, the inherent lack of radio frequency performance of the device, and the phenomena of blocking and spurs, which will cause interference to the network and affect network performance. Only through large-scale The problem can only be solved by replacing the RRU of the original 3G equipment; secondly, TD-LTE uses the time division duplex mode, and the uplink and downlink time slot ratio determines the time resource allocation of the two schemes. The F-band upgrade scheme will cause the downlink capacity to decrease by about 25 Third, the TD-LTE technology is quite different from the existing 2G and 3G networks, and puts forward different requirements for network optimization. The upgrade plan will increase the difficulty of network optimization for operators in the later stage.

However, ZTE believes that the upgrade solution can not only achieve rapid deployment, but also help operators save investment. In terms of cost, the investment cost of equipment newly built using the F-band is nearly 50% higher than that of upgrading the F-band. However, if the D-band is used for construction, the same coverage area in the same area will be constructed using the F-band only, and the D-band only. In comparison, the D-band needs to build about 26% more base stations. Relevant persons of ZTE believe that if the existing 3G network of a city meets the requirements of the LTE network structure, the F-band upgrade is the most reasonable solution. Only when the structure of the 3G site is not reasonable, such as the site, station height, and station If the spacing is not reasonable, it is necessary to adopt a new construction method for this part.

Global 4G users broke 100 million

Regarding the timetable for bidding for China Mobile's 200,000 base stations, many equipment vendors are reluctant to comment publicly, saying only that they have made all preparations. "Everyone says it's fast, it's fast, maybe it's really fast." One person from the equipment manufacturer said.

Some equipment vendors said privately that no matter when the 4G license is issued, China Mobile ’s 4G network construction is basically certain this year, which means that China Mobile has been asked to make a quick decision in time.

According to Ericsson ’s “LTE Roadshow” event held in Guangzhou on June 20, according to GSA statistics, as of May this year, there were already 175 LTE commercial deployment networks worldwide, and it is expected that 87 countries will deploy 248 by the end of this year Commercial network. In terms of LTE terminals, there are currently 97 manufacturers offering 821 commercial products. Global LTE users have exceeded 100 million, reaching 107 million. In terms of shipments, Ericsson has accounted for more than 50% of the global LTE market share. Currently, nine of the top ten mobile operators in the world by revenue have chosen to cooperate with Ericsson.

Ericsson predicts that by 2018, the number of global mobile users will exceed 9 billion, and the number of smartphone users will exceed 3 billion, especially the deployment of LTE networks will enter an explosive period.

"This year will be the beginning of China's 4G." Eric Chang, China's chief marketing officer, Chang Gang believes that more and more innovations and applications depend on the mobile communication network as an infrastructure. "For example, mobile healthcare has deployed After 4G, doctors can transmit the CT scan results to the hospital in real time in an ambulance, so as to make timely pre-judgment. "

GSA data shows that it also reached 50 million users, GSM took 60 months, WCDMA took 48 months, and LTE took only 34 months, which means LTE has become the fastest growing communication technology in history .
