                      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
                      a Qualcomm subject matter expert (SME) worked at the                                                    • EV-DO Site Placement

                      The Qualcomm SME identified several pre-deployment
                      projects, including the creation of a network Request for
                      Proposal (RFP) document; an evaluation of infrastructure
                      vendors; and an assessment of the operator’s capabilities and
                      deficiencies.
