The project introduces the jinnan evergreen building indoor distribution system source new engineering design and construction. In order to improve the signal transmission and communication flow and the improvement of speed, to the design and implementation of planning project jinnan evergreen building room. Project specific implementation to evergreen building is located in tianjin jinnan street no. 75, chongqing underground, the 19th floor on the ground. Evergreen building 4 g CDMA coverage B1-19 f before modification and the elevator, WLAN coverage B1-19 f, good network signal. This project adopts two RRU F network as the information source, installed on the 2 F network room, 20 F elevator equipment room, through the F/L combiner subsystem and road, with the original CDMA room to LTE signal coverage of building, covering the area of about 2.6 square meters. For engineering of efficient and customer satisfaction when the installation of the equipment should be strictly carried out in accordance with the rules and regulations. Strictly control technology of the closed to prevent all kinds of serious accidents to zero accident efficient to complete the project. After reforming evergreen building 4 g LTE coverage B1-19 f and 4 elevators, network signal is good. Adjustable measurement with the base station system (applicable to the equipment supplier shall be responsible for the base station system test, only meter column construction units with the recruitment.) With networking adjustable indoor measurement cloth single-core power cable (below 16 was) indoor protection 2 core power cables (16 was the following), indoor cloth 3 core and 3 + 1 core power cable (indoor put tie soft fiber design drawings have building plan, building annunciator installation drawing and communication equipment distribution and so on. The project complete at the same time, we also want to do engineering budget and inspection standard. |
