| Self-synchronizing a CDMA cellular network
|
1999-09-09 |
| This paper describes the concept of utilizing the normal messaging of mobile stations operating in an IS-95 CDMA network to transfer time between various BTSs (Base Station Transceivers). IS-95 is a time-synchronous system in that all BTSs operate from a common time reference, which is specified to be the same as the time scale used by the Global Positioning System (GPS). This design choice provides the CDMA network with several advantages over an asynchronous design, but does require some means to distribute time throughout the network |
