Radio signals its way to the future
Article Abstract:
Radio quality in car and portable radios can be improved with Digital Audio Broadcasting (DAB), which is being developed in Europe. Multipath interference, experienced on FM in cars, can be avoided by DAB masking techniques. DAB splits each station's signal into several carrier frequencies, so retuning while travelling is unnecessary. Frequency blocks would reduce every frequency's data rate by 1000, limiting interference. Satellite transmission could distribute transmission over large areas and would facilitate radio networks in poor countries.

Ping! - it's Mars on the line
Article Abstract:
Vinton G. Cerf was the co-inventor of the Internet Protocol, with Robert Kahn. He argues that he became especially interested in e-mail due to a hearing loss. The Internet took off in the 1990s, but was invented in the 1970s, and Cerf has decided to look ahead 20 years in his next project. He combines business interests at MCI Worldcom with research interests and is seeking to develop a Space Internet. This project involves technical difficulties relating to the time it takes for messages to travel in space.

Mobile market decides to grow up
Article Abstract:
The UK mobile phone market is expected to expand by 33% in 1996. This is a lower rate than in previous years, but sales will become less seasonal, being no longer concentrated in the pre-Christmas period. Around 10% of the population now own a mobile phone, and there is considerable potential for greater penetration. Consumers are now seeing mobile phones as a useful item, rather than simply a fancy extra.
