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.
