Do not ignore continued investment in existing mission-critical analog and P25 voice systems because you believe voice over LTE broadband that is mission-critical is just around the corner. Many elected officials in federal, state, and local agencies seem to believe this so continued investment in existing channelized voice systems is not needed. While a lot of progress is being made in the world of broadband voice, it will be sometime in the future (undefined) before all of the pieces and parts of mission-critical voice as defined by NPSTC are included in LTE. Even then there may be limitations that will hinder the Public Safety community or require some changes to how voice systems are used today.
