Title: Telephone system with relay stations - has fixed and mobile subscriber stations forming transmission network
Inventor: HEROLD WOLF DR ING
IPC: H04J13/00
Filed: 1973-12-22
Abstract: Simultaneous access of mobile stations to the allocated relay station is realised in the same frequency band by the code multiplex method, in which individual address codes form transmission channels.
