                      Collaborating with Qualcomm experts
                      The project required close coordination between Qualcomm
                      ESG and the operator’s engineering team. To ensure
                      successful communication and collaborate with the operator,
                                                                                                                              Key Considerations

                      The Qualcomm SME identified several pre-deployment
