TECHNOLOGICAL SOLUTIONS FOR THE TRANSMISSION OF THE GSM SIGNALS IN CONFINED AREAS
Marc Heddebaut · 1993
This paper explores the feasibility of expanding the coverage of radio frequency systems to confined areas. The system considered is the GSM ( Global System for Mobile telecommunications) which works into the 900 MHz frequency band. The paper considers the electromagnetic problems involved and gives elements to choose a radiating system among three different technologies: antennae, leaky feeders, and mode converters.
