Problems solved by technology

However, in this current method, the number of antennas and the optimal position of each antenna are still determined by technicians, and only simulation tools are used to evaluate the wireless signal coverage effect
By manually changing the number and location of antennas deployed many times, the indoor wireless signal coverage effect can be guaranteed to meet the needs of telecom operators. Therefore, this method also has a huge workload, and cannot guarantee the final number and layout of antennas. The location is the best, only to meet the needs of network construction
According to the information consulted by the inventor, there is currently no document that records the method for automatically determining the distribution of indoor antennas.

Abstract

The invention discloses a grid-based automatically-determining indoor antenna requirement and arrangement method. The method comprises the following steps: firstly, utilizing a grid modeling module to build antenna position grids and target user location grids; secondly, calculating the field strength and the coverage rate of a target coverage area; finally, automatically determining antenna quantity and antenna positions meeting coverage requirements of users eventually through an iterative loop. The method can automatically determine the minimal antenna quantity and the optimal antenna arrangement positions meeting the requirements of the construction of an indoor wireless network, so that the design efficiency and the quality of an engineering technical worker are improved, design labor is saved, and wasteful investment is avoided; the method is is practical and effective, and easy to realize and popularize.

Description

technical field [0001] The invention belongs to the technical field of communications, and relates to a method for determining the distribution of indoor antennas, in particular to a method for automatically determining the requirements and arrangement of indoor antennas based on gridding. Background technique [0002] Indoor is the main scenario where mobile communication services occur, and the indoor wireless communication network carries most of the user's communication traffic such as voice and data. The signal source of the multi-antenna indoor distribution system is relatively pure, the interference is relatively small, and the signal source power is evenly distributed indoors, which can attract indoor user traffic, so it is currently one of the most important indoor wireless network solutions for telecom operators. [0003] A major issue in the engineering design of indoor distribution systems is how to design the number and location of each antenna in the indoor dis...
