Radio Frequency engineering is an important yet often overlooked area in today's wireless world. This course provides a grounding in RF theory and practice for wireless, cellular and microwave systems.
Those working with wireless, cellular and microwave systems.
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.
Transmitters: Antennas: Isotropic, Dipole, how antennas achieve gain.
Schemes, bandwidth, AM, FM, FSK, PSK, QAM,
QPSK, interference, performance.
Hands on Interference and performance.
FDMA, CDMA, TDMA, CSMA/CA.
Cellular (GSM, UMTS), Wifi, WiMax, others: GPS,
DBS, RFID, radar, Bluetooth.
Hands on cellular.
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
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.
