Spectrum management

The event launched the Plum Consulting study on behalf of Cisco on the case for more spectrum for Wi-Fi.  Speakers included:

          • Mr Hokmark, MEP
          • Brian Williamson, Plum Consulting
          • Roberto Viola, Deputy Director-General DG CONNECT
          • Jim Scott, Managing Director Mobility Vertical EMEA – Cisco
            The study recommended that the European Conference of Postal and Telecommunications Administrations (CEPT) assess Wi-Fi sharing additional spectrum at 5 GHz, as shown see below (where DFS refers to a detect and avoid technology to enable to Wi-Fi to share available spectrum).   The full study is available

          .

This change would offer two key benefits:

        1. The additional spectrum would increase Wi-Fi capacity by 95%, even though the amount spectrum is only increased by 70% (since it would allow the removal of guard bands in the middle of the band) 
        2. The availability of a larger contiguous block of spectrum at 5 GHZ supports wider channels which, with the 802.11ac Wi-Fi standard, would support significantly higher speeds
