What are the interfaces between the BTS and MS&& BTS and BSC?

BTS and MS:

- Base station subsystem is a segment of cellular telephone network that is responsible for setting signals and traffic between mobile phone sets and network switching subsystems.
- Transcoding of speech channels are carried out by BSS. BSS allocates radio channels to mobile phones, paging, transmission and reception over the air interface and many other tasks that are pertaining to the radio network.
 BTS and BSC:

- Base Station Controller provides the intelligence behind the BTSs. A BSC conrolls hundreds of BTSs.
- Allocation of radio channels, receiving measurements from the mobile phones are some of the major task handlings by BSC.
- BSC controls BTS to BTS.
- BSC acts as a concentrator in which many different low capacity connections to BTSs will become reduced to few numbers of connections towards the mobile switching center.
- BSC provides the required data to operation support subsystem(OSS) and also to the performance measuring centers
- BTS supports the key features like, frequency hopping, sectorization, and GPRS.
- The expansion and upgradation in the field are the features emphasized during its design.
- The power output of BTS is up to 80W.
