The Telecommunications landscape is in a
constant flux of change. For the Non-Technical professional, Technical
competence is strategic in this ever-changing Industry. The ABCs
of Telecommunications is a three (3) day course which provides Non-Technical
Professionals the fundamental Technical concepts in the area of
Wireless and Wireline Technology.
The course starts from a discussion on Modulation and Multiplexing
techniques and proceeds to branch out into Wireless Technologies:
AMPS, NMT, TACS, GSM, GPRS, HSCSD, EDGE and Third generation technologies.
Transmission Technologies are also covered: PDH, SDH, Wireless local
loop.
For the Wireline Technologies, the course branches into Telephony,
Intelligent Networks and Data communications: LAN and broadband
networks: ATM, Frame relay, ISDN. New Technologies such as Bluetooth,
Multimedia Messaging and Wireless LAN Technologies are also discussed.
A discussion on Telecommunications business trends is also covered.
The Non-Technical Professional will highly benefit from this three
(3) day course and will form a foundation for the individual to
branch out into the more Technical courses under Telecommunications.
