System Overview
A few days ago, the Guangdong Provincial Communications Administration announced the base station construction data of basic operators in the first half of the year. Statistics show that the number of mobile communication base stations in Guangdong Province this year has reached 612,000, while the number of mobile communication base stations nationwide has reached 6.24 million. The energy consumption of the base station is mainly electricity. With the increase of electricity costs and the expansion of mobile networks, the electricity expenses of the base station computer room are gradually increasing.
According to data, taking a base station in a certain area as an example, its annual electricity expenditure is as much as 25,000 yuan, and the base station air-conditioning electricity expenditure accounts for a larger proportion.
According to statistical analysis, the average electricity expenditure of each base station air conditioner accounts for about 54% of the entire base station electricity expenditure. Air conditioners have become the main power-consuming equipment in the base station computer room.
Total power consumption of base stations nationwide: 6.24 million base stations x 25,000 yuan per base station 156 billion yuan
The total electricity consumption of base station air conditioners nationwide: 156 billion x 54% = 84.24 billion yuan
If the national industrial electricity consumption is 1 yuan/kWh, the annual base station air-conditioning power consumption exceeds 84.24 billion kWh, and roughly calculated, 1 kWh electricity bill needs to emit 0.87kg of carbon dioxide. That is, a year is equivalent to 73.2 billion kilograms of carbon dioxide emissions. Therefore, energy saving and environmental protection in this solution greatly reduces power consumption while ensuring the coverage of the base station remains unchanged, and truly achieves the perfect coexistence of high-quality mobile networks and green environmental protection.
Because the communication base station plays an important role in the wireless communication system. The communication signal is mainly transmitted through the base station. The base station transmits the signal received from the mobile phone to the server, and the server sends the signal to the base station after processing, and the base station sends it to the target mobile phone to complete a communication.
Anrecson industrial computer mainly implements the necessary maintenance and management functions in the portable base station subsystem. Therefore, the portable base station no longer requires a large amount of floor space, base station tower, computer room, and power supply system to the traditional communication base station in the past, thus greatly saving energy and resources.
System specification
GSM base station is mainly composed of three parts: base station subsystem (BSS), network subsystem (NSS), and operation and maintenance subsystem (OSS). And each subsystem is a huge and complex system. I won’t go into details here, but only introduce the main functions of IPC-606 in BSS at present. The BSS base station subsystem includes two parts: BTS and BSC. IPC-606 carries LMT maintenance software and is connected to BTS, BSC, transmission terminals and other equipment. So as to realize the management and maintenance of local equipment:
BTS includes the following main functional units: Transceiver Radio Interface (TRI), Transceiver Subsystem (TRS). The TRS includes the transceiver unit (TG) and local maintenance.
TRI has a switching function, which makes the connection between BSC and TG very flexible; TRS includes all wireless devices of the base station; TG includes all wireless devices connected to a transmitting antenna; LMT is a user interface for operation and maintenance functions, which can directly Connect to the transceiver.
The transmitter subsystem includes all the wireless equipment of the base station, mainly including the transceiver unit (TG) and the local maintenance terminal (LMT).
A transceiver unit is composed of multiple transceivers (TRX) connected to the same transmitting antenna.
Outdoor small BTS should support the following capacities: Omnidirectional BS should support the following configurations: 1-2 TRX and 1 2MBit/s port.
For the above configuration, when required by the operator, it should be able to expand to a larger configuration while recording the reduced impact on the actual operation, and the BTS can be expanded on site.
System Requirements
Since the system is actually arranged in a closed aluminum alloy box, the box contains IPC-606, RS-485 ARK data acquisition module, 4G module, signal transceiver and other system modules, the overall layout is relatively compact, and equipment interference Larger, the temperature of the case is higher, and if it is installed on an outdoor pole, the temperature is higher.
Anrecson industrial computer has the advantages of energy saving and environmental protection, small size, flexible installation, excellent wide temperature performance, and ultra-low power consumption. It is the first choice for this type of customer to choose it as a small mobile communication base station controller.
