7. doc.: IEEE 802.15-06/??r0 TG4a PresentationSlide 6 Detect and avoid (DAA) Offers protection to incumbent services by detecting their presence and not transmitting in their band Minimises interference while allowing UWB operation where possible But the DAA problem is challenging – how to avoid the hidden terminal problem? Any solution needs to be: –Highly accurate –Low cost –Spanning a range of different services –Agreed by all parties ETSI asked to work on a DAA specification in parallel to TG3 work – expect this to take some time

8. doc.: IEEE 802.15-06/??r0 TG4a PresentationSlide 7 Low Duty Cycle (LDC) operation Restrict the time that a device can transmit to limit the harm that it can cause to other services Possible problems with LDC –Will still cause some harm to incumbents –Limits what the UWB device can be used for –Agreement largely depends on acceptance by incumbents

9. doc.: IEEE 802.15-06/??r0 TG4a PresentationSlide 8 The “interim measure” The 4.2-4.8GHz band is currently free of users likely to suffer significant interference from UWB (although NATO actively lobbying against allocation) hence no additional restrictions are currently needed However, it is possible it might be identified for 4G at some point Our view is that it should be used by UWB until future uses are identified, then regulations can be changed if appropriate Advantages Somewhere UWB can immediately go Reduces the likelihood of illegal US imports Increases the possibility of a world-wide UWB standard Maximises spectrum utilisation and consumer benefit Disadvantages Might require a migration process in due course Band clearance, if needed, could take many years

10. doc.: IEEE 802.15-06/??r0 TG4a PresentationSlide 9 The longer term vision – above 6GHz There are fewer interference issues above 6GHz – this is mostly because given the type of service to use this spectrum proximity with a UWB device is less likely However, at present devices cost more to manufacture and the range is lower –Manufacture costs will drop over time –We are in favour of considering an increase in the allowed power above -41dBm in parts of the 6 - 8.5GHz band to overcome the loss of range Critically, we believe it should be the market, not the regulator, that decides on whether this transition is appropriate and when it should occur and that is why we support the interim approach.

11. doc.: IEEE 802.15-06/??r0 TG4a PresentationSlide 10 What’s next in the regulatory process Europe has largely reached consensus on most issues – an outcome that did not appear possible at one time Main issue of controversy is interim allocation in 4.2 - 4.8 GHz Still a lot of work to be done on DAA and LDC. Closing date for comments on EC consultation 19 th May. Closing date for comments on ECC consultation 29 th May. EC decision on UWB above 6GHz likely to finalised in June. ECC decision likely on UWB below 5GHz in July. EC are then likely to mirror ECC decision below 5GHz. EC would normally place max 6 month timescale on implementation dates for nation states.
