In May 17th, China Mobile comprehensive reduction of GSM charges, amounting to 15%~40%, at the same time in the global set within a substantially increased Internet traffic. This action, the industry is expected, the result data service and old equipment has been more pressure on GSM network, will usher in greater test.
Plus China Mobile since this year the largest GSM expansion is expected to purchase results recently published, it also further stimulate the local GSM network expansion project to accelerate the.
All progress is not a
3 early Securities Agency issued a report, called the China Mobile is conducted 2011 GSM network expansion bid $2000000 carrier frequency. Although this number has not been confirmed but China Mobile China Mobile, previously on the capital market for 2011~2013 years capital spending plan respectively 132400000000 yuan, 130400000000 yuan, 125600000000 yuan, than previous market expectations have grown substantially, but in 2011 GSM expansion due to strong demand, the TD network investment will be reduced.
Due to the current GSM network to replace the old equipment proportion is larger, plus the site resources, producing electric resource is nervous, so the GSM expansion in addition to a base station equipment procurement, also includes power matching, matching, matching equipment such as base station transmission.
In many places in the reporter that communication, different province city branch in GSM expansion project in addition to the building is a, time is different. For example, Jiangsu mobile is just the fourteenth phase expansion project, the scale of approximately 90000 a carrier frequency, the number of base stations each month according to the demand of the emergency degree partial report.
Beginning in March, Guangdong Mobile GSM fifteenth phase expansion project to add frequency 6900; Guangxi mobile GSM fifteenth first stage of expansion project includes new base station base station 1129, relocated in 11; Zhejiang mobile GSM expansion and technological transformation project has been to eighteenth.
In 2010 China Mobile GSM network expansion was carried out on the 1000000 carrier purchasing amount. In 2011 the GSM expansion of guidance, Huawei, ZTE, China Mobile on Nokia Siemens Communications 900MHz, 1800MHz expansion device relatively high satisfaction. Securities Agency forecast, at this year's GSM expansion in the procurement of ZTE is expected to take nearly 20% share.
Multi carrier, to increase the proportion of distributed base station
According to the GSM expansion at the end of 3, China Mobile issued a 2011 GSM network construction guidance.
The new base station requirement, mobile group to put as much as possible around the common base station, based on the same BSC construction 900MHz, 1800MHz base station, " foot " 900MHz perfect coverage; and to accelerate the introduction of 1800MHz improve the capacity of the network, promote the two network traffic balance, and suggested to vigorously promote the multi-carrier base station, a distributed base station, C-RAN, application of new technologies such as MSC POOL; also asked to remote areas using " distributed base station remote coverage ", " power ", with " base station tower ", " to replace the high gain antenna ", " super-far coverage technology ", " the tower covers " and other technology to carry out edge network construction, reduce the new station siting.
China Mobile Design Institute of radio by a project manager is also mentioned, the GSM expansion is mainly based on multi-carrier and distributed base station, address the room shortage, at the same time, many system under wireless environment is more and more complex, the GSM expansion project will focus on solving system and save the system interference problem. " In the new technology, 3G distributed base station in 2G network application is a good method, can solve the problem of computer resources. "
