Problems solved by technology

This calculation method is mainly based on the total construction investment of each scene and the actual coverage area of ​​the wireless signal (the actual coverage area of ​​the wireless signal is less than or equal to the building area). It is difficult to effectively obtain the actual coverage area of ​​wireless signals, resulting in a large gap between the cost calculation results and the actual construction investment and investment
For example, when making statistics on the historical samples of the target area, it is difficult to test the actual coverage area in each construction area, and there are a lot of human factors (underreporting or raising the average construction cost) in the process of reporting data, resulting in deviations in the final measurement results
The scene to be built has no signal coverage yet, so it is difficult to estimate the actual coverage area of ​​the wireless signal. Reporting the actual area of ​​the building will cause the statistical area to be too large and affect the calculation results
Second, this method is only for the cost test of the indoor distribution system, without considering its supporting transmission equipment and access optical cables for calculation, resulting in inaccurate calculation results of the total cost of the one-way project

Abstract

The invention discloses a comprehensive cost method and system for an indoor coverage project, which belongs to the technical field of mobile communication, including obtaining the construction sample data of a historical indoor sub-system in a region, obtaining the building area covered by a single source; using a single source to cover the building area and Based on the actual building area of ​​the construction project, calculate the number of signal sources required for the project to be constructed; based on the base station optical cable access strategy of the project to be constructed, determine the number of signal sources connected by a single optical cable; according to the number of signal sources required for the project to be constructed and the number of signal sources connected by a single optical cable to determine the number of source groups; use the pre-set cost calculation model to process the number of signal sources and the number of source groups required for the project to be constructed, and calculate the comprehensive total of the sub-systems of the project to be constructed. cost. The present invention sets different calculation models and adds the cost of the access optical cable and the cost of the transmission equipment to the comprehensive total cost, so as to better match the actual project composition.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a comprehensive cost method and system for indoor coverage engineering. Background technique [0002] As the current urban buildings are getting taller and the construction area is getting bigger and bigger, due to the limited penetration of wireless signals, the construction of outdoor macro base stations and micro base stations alone cannot meet the indoor area communication requirements, so indoor distribution systems have emerged as the times require. The indoor distribution system is a successful solution aimed at indoor user groups and used to improve the mobile communication environment in buildings. It uses the indoor antenna distribution system to evenly distribute the signals of mobile base stations in every corner of the room, so as to ensure that the indoor area has ideal coverage. signal coverage. According to different transmission media, indoor distri...
