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.
