The Commission makes these changes to reduce uncertainty in the rules and harmonize the rules. The intended effect for public safety licensees is to allow additional flexibility, create opportunities for public safety users to benefit from speedier deployment of new technologies in the 4.9 GHz band, and lead to expanded use of 4.9 GHz broadband networks. The intended effect for manufacturers is to allow technologies similar to those covered by part 15 to be used in the 4.9 GHz band, resulting in speedier deployment of new technologies in this band. The intended effect of the cross-banding rule change is
