GRCon 2012: SIMONES

• Develop simple, unaFended operaGon and low cost monitoring units. •  Support spectrum monitoring and management tasks. • Complement commercial units with specific funcGonaliGes that are not standard in internaGonal systems.

SIMON

•  TESData and Web Interfaces.


TESData

•  Spectrum monitoring tool. • Developed by TESAmerica in Colombia, widely used in LATAM. • Perform measurements. • Program measurement plans. • Control mulGple devices.

DEMO Demo video 1: TESData and the USRP.

Web Interface

•  The foundaGon of a new version of TESData. •  The interacGon model for spectrum analysis has been the same since 1960s. •  Legal concerns are based on frequency allocaGon tables. • Consider the experience of TESAmerica.

GUI concerns

•  Frequency allocaGon table. •  Start frequency. •  Stop frequency. •  4MHz detail.

• Current services in the band. • Reduce the learning path.


DEMO Video demo 2: How it looks.

What are we working on?

•  Improve remote processing tasks. •  There’re six related presentaGons, today!!!

• Add TESData funcGonaliGes to the web applicaGon. • Add automated measurement and spectrum management tasks to the SIMON. •  IdenGfy possible license violaGons.

•  Evolve to ControlPort.


Future work

•  Strategic program in spectrum management. •  TESData 2.0 and SMS4DC. •  RDFS (Radio DirecGon Finding). •  GNU Radio 3.7 and new devices: MEDAV and ETTUS.

• Wireless communicaGons laboratory. •  Undergraduate program of TelemaGcs Engineering. •  GNU Radio based tools. •  DVB-‐T2 STB.
