What kind of training should I do if I want to find a job of network maintenance and optimization planning after graduation from undergraduate communication engineering? Are there any good training institutions? Both ZTE Huawei and MOTO(CP02 BSS 1 1) have primary network optimization training and certification. Work experience (orz) is required, mainly familiar with OMC of several manufacturers, traffic statistics, wireless parameters, and training is a bit expensive. I also understand the details. Let's add a good friend to each other. I also communicate and help each other. Personally, Cisco is too difficult. .
