SLC
SLC: conduction and radiation software
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
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
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.
