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.

RF systems
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.

Modulation
Schemes, bandwidth, AM, FM, FSK, PSK, QAM, QPSK, interference, performance.
Hands on: Interference and performance.

Multiple access schemes FDMA, CDMA, TDMA, CSMA/CA

Wireless systems
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.

RF propagation 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.

RF testing 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
“Excellently presented by a very knowledgeable and enthusiastic trainer.” P.D. General Dynamics

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.
