I feel HedEx is great tool to get all techanical knowledge. I joined Huawei couple of months back & didnt get chance to have traing on Huawei LTE stuff however, with help of HedEx, I never feel need of training to get through the huawei features and counters. HedEx is really is very helpful as it covers all knowledge in very systematic way. It includes all meaning, definations, engineering guidelines, related parameters & counters. Really apriciate it. Thanks.
