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.

Wireless Communication, The Very Basics | ||||
Introduction to wireless communication systems | Video clips one by one | ||||
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 | ||||

![]() 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 | |||

![]() 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". | ||||
![]() | 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 | |||
![]() 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 |
