High-end commercial buildings, airports, large venues, large shopping malls, high-end residential communities and other large traffic and VIP scenarios are suitable for co-deployment of MIMO solutions. What are the advantages of this solution? (Multiple choice)
Which of the following types of warm wires are commonly used? (multiple choices)
Before coverage analysis, it is necessary to obtain basic data such as the planning plan, site distribution, base station configuration, antenna feeder configuration, RS power and service load characteristics of the optimized target area. Then obtain the information of the existing network data, conduct a comparative analysis, and find out the areas where the coverage problem may exist.
