  • Extended range TDMA system
    Patent number: 5615215
    Abstract: A TDMA radio communication system such as GSM has a limited time period (td) over which the transmission from a mobile station (MS1 . . . MS5) can be advanced to allow for the transit time of the signal between the mobile and the base station (BS), and this limits the maximum range of the system to radius R1. By co-locating a first transceiver (TX1/RX1) operating on a first frequency band (F1) and a second transceiver (TX2/RX2) operating on a second frequency band (F0), and delaying the reception time slots of RX2 by td, the first transceiver can be used for communication up to radius R1, and the second transceiver can be used for communication for mobiles between radius R1 and radius R0. Idle mobiles are instructed to camp on F0 and RX1 is switched during access request periods to look for access requests on F0.
