7. doc.: IEEE 802.11-04/311r0 Submission March 2004 Peter Ecclesine, Cisco SystemsSlide 7 US NTIA Position Create a low tax and limited regulatory environment that promotes our growing economy. Work with industry and government engineers to reduce interference and promote spectrum “best practices”. Remove government obstacles to development of new communications technologies and applications. Use sharing where technically feasible to increase the amount of spectrum available for wireless services and streamline the process of licensing when licenses are required.
