Abstract

PURPOSE:To enable an arbitrary communication between radio sets and to achieve high performance communication for electric works, by containing each communication set to a relay device possible for the change in elecromagnetic waves and picking up and using it as required. CONSTITUTION:Six sets of communication sets 6 are respectively contained to each bed set of a relay device 1. Each set 6 is provided with a receiver 7, a microphone 8 and a handset 9. The relay set 1 incorporates an electromagnetic wave modifier and receives radio communication from the set 6, modifies it into different electromagnetic waves and makes transmission to the respective set 6.
