SLC

SLC: conduction and radiation software

Attention, ouverture dans une nouvelle fenêtre. Imprimer

  SLC tool is the SILICOM simulation software calculating waves propagation prediction  depending on the following modes : 

1. The radiation from a transmitter EM to a receptor RC

2. The conduction of the wave generated by a source EC along a cable and measured by a probe SO

3. The coupling wave radiated by a transmitter then the conduction of this wave measured by a probe

4. The conduction of the wave generated by a source EC along a cable whose radiation is captured by a receptor

SLC components and applications

Attention, ouverture dans une nouvelle fenêtre. Imprimer

  Simulation components are following : 

· Radiating noise captured by the receptor and diffused noise along the cable

· The source is defined by the power, the frequency, the antenna (radiating pattern), gain vs. frequency, elevation an azimuth angles, and the transmitted spectrum

· A source is defined by the tension, the frequency and the spectrum.

· The cable is defined by the geometry (details of sub-segments), the section, the impedance, the loads RLC…

· The receptor and the probe are defined by the antenna, the tuning frequency and the selectivity

Some application examples 

· Base stations et cellular mobile communications (GSM, GPRS, UMTS, DECT…),

· Wireless transmitters (WiFi, 802.11, Bluetooth, RLAN),

· Hardware devices  (screens, cables, computers, wire less keyboards-mouse),  

 

SLC Physical models

Attention, ouverture dans une nouvelle fenêtre. Imprimer

Propagation models included in SLC software simulate phenomena between 50 Hz and 5 GHz in various environment types :

· Indoor

· Outdoor

· Both

For propagation mode, SLC software uses various radiation models in order to provide field level, from a transmitter at a defined position ( a receptor position or a point along a cable) :

· Free path losses

· Indoor  model : 3D ray tracing

· Deygout model

· Outdoor model : Deygout + 3D ray tracing 

For conduction or coupling mode, the SLC software uses :

· Simple model from open source

· Built model from electromagnetic software (MoM). 

SLC software provides various maps :

· Field level

· C/I level taking with the noise

· Best server » positions

· Rate

Optimisation  method, based upon  image treatment, allows to obtain these kinds of results (ray tracing in-door, reflexions and transmission) in a time of less than 1’30 per transmitter.
