Interviews with experts who laid the foundations of modern wireless communication. The playlists of these items are in M3U format. M3U playlists allow winamp or other media players to play a sequence of audio and video clips, streamed with the http protocol. Some of these interviews have been broadcast on our Internet radio station in 1998 - 2002, and are now available as podcasts.

	Interactive learning web pages	Wireless Communication, The Very Basics A presentation by Tim Moulsley addresses applications, standards, services, technologies for the novice. Just listen to his talk or use the interactive version with quiz questions.
		Introduction to wireless communication systems		Video clips one by one
	history.m3u	History of Communications by Randy Katz. From smoke signals to the Internet. Starting with muscle powered communications, all the way to modern wireless multimedia.		Text Slides
	massey.m3u	Jim Massey "Coding Theory, the Phoenix of Communication".
	diversit.m3u	Diversity Reception An explanation of why diversity helps in a multipath channel, the basic principles of various diversity methods, why Maximum Ratio Combining performs best. The playlist continues with interviews with Ernst Bonek and Zeke Bar-Ness. Smart antennas and interference cancellation become increasingly important.		Text Slides
		CDMA and the Internet by Phil Karn		Text
		Multiuser Detection by Sergio Verdu
	pgrant.m3u 49'02"	CDMA Array Processing by Peter Grant, Distinguished IEEE Lecturer. Multipath propagation, CDMA systems, Array Processing, performance results.		HTML tekst, listing of audio files.
	randacc.m3u 32'19"	Random Access Data transmission differs from circuit-switched telephony. Particularly for bursty data or multimedia traffic, random access schemes are needed. The ALOHA system was the first implementation of a wireless packet data network. Such networks can exhibit instability problems. Boris Tsybakov invented the "stack algorithm" to ensure stability. Similarly, Frits Schoute's "Dynamic Frame Length ALOHA" also is stable. Jim Massey's "Protocol Sequences" allow guaranteed throughput even if no feedback is available.
	massey.m3u Preview.	Jim Massey In an interview Jim Massey covers his protocol sequences that allow reliable random access even if no feedback channel is present. After that he presents his talk "Coding Theory, the Phoenix of Communication".
	story.m3u	The Story of Big Solitude and Mostly Silent. How to explain GSM to your kids? This fairy tale presents the digital TDMA cellular system, using mediaeval technology, i.e., messages attached to arrows shot from bows, and scratch-paper signal processing.		Text
	aes.m3u 55'46"	Copy Management in the Digital Era, AES Workshop, Amsterdam, May 1998 Paul Jessop of the IFPI describes the position of the music industry regarding illegal copying of music. Technological measures to protect content include watermarking, a spread-spectrum type of technology to embed copyright data into the music itself. Markus Erne covers the state-of-the-art. Lawyer Don Jerrard is an expert on consumer's rights-to-copy and "fair use."		Slides and One by one
