The issues of spectrum efficiency, transitioning to IPv6, transitioning away from the PSTN (Public Switched Telephone Network) to an all IP Network were discussed in detail at the Federal Communications Commission’s Technology Advisory Council's (TAC) second 2011 meeting held yesterday. The chairman of the Spectrum Efficiency working group Dennis Roberson, who is a vice provost and research professor at the Illinois Institute of Technology, presented the key points that the working group recommended to TAC. These included the development of spectrum efficiency metrics, receiver standards, spectrum sharing taxonomy and the acceleration of small cell deployments and spectrum sharing. Further, the group recommended removing application friction points that potentially inhibit the deployment of public and private applications such as utility and public safety applications on wireless carrier networks. The committee recommended doing more research on the types of needs from these applications that can be offloaded onto carrier networks to ensure better spectrum efficiency. To that the end, the working group seeks to solicit input at an action-oriented FCC sponsored workshop involving the various constituencies. They aim to make specific recommendations on this issue at the next TAC meeting.
