subject: Around The Base Stations, Base Station Into The Cost Cell Coordination Exorbitant Rent And Owners [print this page] In the communication network construction, the construction of base stations is essential, the three major domestic carriers have invested heavily for this. Mobile communication base stations to provide wireless communications coverage of the necessary means, which provide access to services for mobile devices, to achieve comprehensive network coverage, or to maintain good cell phone signal, you must set up the base station, or will not be able to provide users with regular communication service .
Along with the continuous progress of urbanization, the influx of urban population is increasing. According to statistics, China's mobile phone users every hundred person ownership has reached 41.6, urban residents of the mobile phone ownership is even higher, both now and in the 2G or future 3G, residential area of network coverage are the construction of mobile operators focus on In the base station construction, undertake the construction of national infrastructure network operators is difficult.
Cell base station positioning difficulties
Neighborhood is more dense urban areas, but also the largest mobile communications user complaints region, 90 percent of district residents will be reflected in the above cell phone coverage is not ideal. Face with row upon row of buildings of varying structure, the only way is through the district in a reasonable set up base stations, in order to resolve the phenomenon of weak signal coverage. This idea does not exist from the technical difficulties, mainly due to the problems faced by human factors, specifically expressed in the following three points.
Electromagnetic radiation hazards
In recent years, increasing awareness of environmental protection, electromagnetic radiation and environmental pollution has become the focus of attention. For environmental advocates, we duty-bound; but for electromagnetic radiation, due to over-promote some of the media, led to a misunderstanding of the electromagnetic radiation that is to launch wireless electromagnetic wave as long as the equipment will cause harm to human body. When the operator for network coverage in residential areas need to set up base stations, residents are often carried out by blocking harmful health grounds, and even interrupt the base stations already in operation, interfere with the normal operation of the national communications network, to the country caused some economic losses.
High rents
Operators set up base stations in residential area is not free, pay to the owners of the venue charges, commonly known as the base rent, the specific amount of leased space under the area to agree. Some residential property or residents in the face to discuss personnel carriers, quote rates ten times higher than the local housing rent your rental amount, in fact, part of setting up the base station only a few square meters of outdoor space, indoor part of not more than 20m2, the actual discount off the rent per unit area even more than the sale price of their houses, so it is difficult for operators.
To stop construction
Operators to set up a base station, several aspects need to complete the work before it is put into operation, such as room decoration, the construction of tower or pole, installation of equipment, power transmission connection of the introduction and so on, the basic work of this series by the different construction units to complete. Some owners do not recognize a letter of introduction, all construction projects need to be charged with costs, such as transmission connection of the need to set up from outside the district or laying cable into the base station, the grounds of the owners to collect all kinds of overhead costs, if operators are not paid on block construction, impact of the construction progress of the normal base station, or even more serious circumstances can not be properly opened up to a year, causing great losses to the state.
Concern excess base station radiation
State Radio Regulatory Commission to conduct on-site monitoring of the base station, especially from residents that the base station to track and monitor the launch, including the largest range of electromagnetic radiation in the 0.2 ~ 0.8mW/cm2, from the national standard "electromagnetic environment health standards" GB9175-88 requirements of a standard (field 10mW/cm2) there is a great margin, and all operating units set up base station radio management office must be approved and tested, such as to determine the technical indicators such as output power, spurious, intermodulation, in line with the national technical standards and ensure standards of electromagnetic radiation in a less than before giving approval. In addition, the State Radio Management Office also requires operating units to ensure their equipment at any time be in good condition, but also track and monitor regularly to ensure that the electromagnetic radiation within the safety limits. Therefore, the residents for the base station radiation is completely unnecessary.
The urban area, the base station transmit power are less than 20W, even lower than the base station configuration high 10W, I came out from the antenna receiving the electromagnetic radiation generally only 0.001mW, electromagnetic radiation is to exponential decay, usually to receive mobile phone Conversion success rate of the signal strength is only 7 ~ 10mW, these values and appliances such as microwave radiation emitted relatively far apart.
Cost a lot of money into the cell base station
Stationed in the base station cell as a result the current increased the difficulty of various unfavorable factors, in addition to district residents resent the base station, but also cost carriers put their own concerns. The major cost of building the base station has the following four aspects.
Coordination fee owners
Operators through the pre-design and survey to determine the new base station within a certain district, certainly need to seek the consent of the owners quarters, which is commonly known as rent station operators. If the owners agree to set up base stations, its follow-up work is the amount of rent negotiations, but often the owners or the property for various reasons to delay or refuse, operators need to coordinate repeatedly to get permission, it stops during the entire rental cost of the property of the required coordination costs for the owners.
Base rent
Rent residential area than in other areas of the base stations are often the rent is higher, though generally less than the area of the base station room 20m2, but generally not less than the annual rent price of a three-bedroom rent, some even higher. And in recent years as rising house prices, rents are increasing the base station, making the operator's costs continue to increase.
Relationship Maintenance fee owners
Once the operators and owners of a plot formed a base station lease between the time the lease contract base period is usually five years. During this period, the equipment operators need regular maintenance, upgrades and even transformation, require the assistance and cooperation of the owners. In order to ensure the smooth conduct of these efforts to build a good working relationship, allocate certain expenses per year to maintain relations with the owners of the lease.
Self-built costs
Operators in the district set up base stations, sometimes the owners will only provide a roof, no spare room as a room rental, so operators need to own the new activities room, an activity room of the cost as high as 30,000. And some communities, owners reluctant to set up base stations in the top of the building, operators will need to create a single control tower, a 30m single-tube towers need 200,000 yuan. In addition, the district residents would be the conventional base station antennas are usually very sensitive and not always feel beautiful, but also hazardous to their health. Operators as they can in the cell base station antenna using landscaping, but the cost of the antenna than the general beautification of the antenna 4 to 5 times expensive. These costs have increased in virtually operator input.
