4 Who are we? What are our motivation? UWB From a Wireless Networking Point of View Very wide bandwidth Trade power for bandwidth: very low emitted power Lots of multipath Random signature for concurent transmitters Excellent robustness against fading Interference not an issue anymore: much simpler MAC design Hard to take advantage of the multipath Have a proper receiver Estimate the channel Channel synchronization and acquisition R.

9 Requirements and Challenges of a UWB Interference Platform Very wide bandwidth RF components must have a wide flat frequency response Antennas, filters, amplifiers, up/down-conversion Platform v1: 500 MHz in the 4 to 5 GHz band Many pulse/signal generators Coherent receiver Fast sampling at several GS/s or analog components? Easily reconfigurable receiver R. Merz 6 / 8
