ISBO NG WiNeTs Demo Storyline Peter De Cleyn IBBT-PATS, University of Antwerp

Demo introduction

 Three separate but complementary demos  One theme: spectrum efficiency  Stacked approach

  Integration path

2

DEMO 1: Sensing Interference

 First step is to measure the spectrum occupancy

 500 Mhz – 2.5Ghz  Large range  Lots of networks to detect  Low Power

 Needed to develop network detection algorithms  Verification of algorithms  Coupling with sensing engine

3

Demo 2: Avoiding interference

 Avoiding interference  Detect bad channel conditions  Avoid using “occupied” channels

 Single sided, non-cooperative  Both parties can use their needed share of the bandwidth

 Demo  Sensor and WiFi networks competing for spectrum

4

Minimizing interference

 We shouldn't waste resources   Collaborating networks can decrease

the usage of spectrum   Communication between

  homogeneous technologies   Optimize routes to minimize hop counts   Minimize channel usage

 Heterogeneous networks   Relay traffic to other networks   Minimize channel usage

 Optimize the available resources over the boundaries of networks and devices

5

Conclusions

 First steps are taken  We will demonstrate techniques which (will) all

contribute to a higher spectral efficiency  Road looks promising

 Refining, extending and, most of all, combining all techniques will further increase spectrum efficiency.
