RF fundamentals training course contents
What is RF?
Definition of RF, RF wave characteristics: Frequency, wavelength, power, phase, impedance, RF history, radio signals, frequency bands, safety issues, legal issues.
Microwaves, cellular/mobile RF, WLANs, other fixed wireless networks, basic RF components.
Hands on: Building a basic WLAN network.
RF system components
Transmitters: Antennas: Isotropic, Dipole, how antennas achieve gain.
Schemes, bandwidth, AM, FM, FSK, PSK, QAM, QPSK, interference, performance.
Hands on: Interference and performance.
Multiple access schemes FDMA, CDMA, TDMA, CSMA/CA
Cellular (GSM, UMTS), Wifi, WiMax, others: GPS, DBS, RFID, radar, Bluetooth.
Hands on: cellular.
Spread Spectrum technologies Spread spectrum benefits and disadvantages, how it works, Direct Sequence, Frequency Hopping, hybrids.
Models, link budget, Smith chart, RF matching with the Smith chart. cell capacity, tradeoffs: power vs. bandwidth, free space, reflection, diffraction, multipath cancellation, propagation prediction and measurement tools.
Hands on: Smith charts.
Why power rather than voltage/current, units of power, dB and dBm power conversions. Test equipment: signal generators, power meters, network analysers, spectrum analysers. RF test setups: return loss, insertion loss.
Hands on: RF testing.
Why Choose Us
SNT trainers score an average of over 90% on the three main areas of:
- Ability to teach
- Technical knowledge
- Answering questions
We limit our maximum class size to 8 delegates; often we have less than this. This ensures optimal interactivity between delegates and instructor.
"Excellent course. The small class size was a great benefit…" M.B. IBM
We write our own courses; courseware does not just consist of slides and our slides are diagrams not bullet point text. A typical chapter provides clearly defined objectives with a chapter overview, slides with text underneath, a quiz at the end to check the learning of the students. Hands on exercises are at the end and are used to reinforce the theory.
