Andrew Stirling (Head of Spectrum Policy for Microsoft in the UK and Europe) discusses how 'nimble spectrum regulation' and sub 1-GHz spectrum usage are key elements of the solution to support the ever-increasing demand for wireless connectivity.

1. The case for nimbleness in spectrum – in brief Comreg event on 21st July 2010 21stJuly 2010

2. Wireless data Growth European digital agenda User interaction Machine to Machine Cloud computing Ad-hoc Image: BBC News - Morph phone The need for a more nimble spectrum framework

3. Finding spectrum capacity for three usage models ? WWAN 2G 3G 4G WLAN Wi-Fi White Spaces WPAN Bluetooth UWB Wi-Gig Distance from the fibre The need for a more nimble spectrum framework

4. Flexibility with certainty Supports central infrastructure investment Enables infrastructure investment by end users Inclusive Hybrid Exclusive Provides greater service quality predictability when demand is high Provides scope for innovation Enables coexistence of multiple users/applications The need for a more nimble spectrum framework

5. Use a database Coordinating spectrum use through a database brings major benefits This deterministic approach provides: Predictable capacity to white space device users Reassurance to licensees Flexibility for regulators to retain control 5 The need for a more nimble spectrum framework

6. Wi-Fi , 5 GHz This slide shows the results of simulating the coverage that could be achieved, with 20% access point penetration, in a 1 km2 dense urban area in Fulham, London. The simulation was repeated for each of the three bands Wi-Fi , 2.4 GHz TV White Spaces – 600 MHz Source: BT Innovate & Design Sub 1 GHz is key to ubiquitous access The need for a more nimble spectrum framework

7. Summary The need for more nimble spectrum regulation becomes clearer Sharing spectrum is the only realistic way to radically increase capacity, for all user groups TV White spaces are the first major opportunity for sharing, with potential to further universal broadband access and help wireless innovation 7 The need for a more nimble spectrum framework

9. Speaker Bio Andrew Stirling heads up spectrum regulatory policy for Microsoft in the UK and Europe. As an ex-regulator, he has significant insights into the issues around digital TV switchover and spectrum management He leads Microsoft’s participation in UK and European proceedings on TV White Spaces. He also facilitates cooperation with Dell, Google and Philips in this key area The need for a more nimble spectrum framework
