Additional WNG topics of interest

This article discusses the ongoing topics of interest in wireless networking, including VoIP over WLAN, lossless data compression, software-defined radio, radio regulatory, and the requirements of WLANs in the future. It also explores the evolution of Layer 2.5, multi-radio parallels, signaling protocols, and the revolution in radio regulation.

  1. Additional WNG topics of interest Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

  2. Topics of Ongoing Interest • Topics of Ongoing Interest IEEE 802.11 04-090 • VoIP Over WLAN • Lossless Data Compression • Software Defined Radio • Radio Regulatory, ETSI/BRAN, MMAC, 3GPP • Requirements of WLANs 10 years from now Peter Ecclesine, Cisco Systems

  3. Larger trends • Evolution of Layer 2.5 - neighborhood awareness • 802.11F IAPP, Fast Handoff, 802.11k Site Report • Evolution of Multi-radio parallels 802.1 bridging into switching • 802.11MES asserts nodes may have multiplicity of radios • Signaling channels, signaling protocols • Evolution of World mode • Over The Air provisioning • Antenna Independent Interface, via signaling to ODU? Peter Ecclesine, Cisco Systems

  4. 802.11 today • Evolution of ‘Listen and Learn’ == evolution of 802.11 • Dissimilar radio detection, recognition and adaptation • Called ‘Cognitive radio’ in regulatory terms, but will generalize • More spectrum will be allowed with better coexistence • Collision Sense Multiple Access, Preamble Sense • 802.15.2 PAN/LAN Coexistence • 802.11h Dynamic Frequency Selection, ‘Other OFDM’ bit • 802.11j Regulatory Class, Coverage Class Peter Ecclesine, Cisco Systems

  5. Near and farther out • 802.11k Site Report • 802.11n channel width detection, channel training • 802.11MES Extended Service Set • . . . • 4.9 GHz Public Safety • Incident Commander controls access • 5.9 GHz WAVE controls access • . . . • Wireless Fast Ethernet • Wireless Gigabit Ethernet Peter Ecclesine, Cisco Systems

  6. Revolution in Radio Regulation • A HORIZONTAL LEAP FORWARD: • FORMULATING A LAYERED POLICY APPROACH TO INTERNET PROTOCOL • with • RICHARD S. WHITT • Director, Federal Law and Public Policy, MCI • http://global.mci.com/about/publicpolicy/presentations/horizontallayerswhitepaper.pdf Peter Ecclesine, Cisco Systems

  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. Peter Ecclesine, Cisco Systems
