This report represents an initial set of guidelines to assist smart grid designers and developers in their independent evaluation of candidate wireless technologies. While wireless holds many promises for the future, it is not without limitations. In addition wireless technology continues to evolve. Priority Action Plan 2 (PAP02) fundamentally cuts across the entire landscape of the smart grid. Wireless is one of several communications options for the smart grid that must be approached with technical rigor to ensure communication systems investments are well suited to meet the needs of the smart grid both today, as well as in the future.
