BTS ConfigurationBTS configuration is determined by the traffic volume and the traffic distribution.BTS configuration is associated with the number of the TRXs and the antenna system.BTS can be omni directionalBTS can be sectored.Number of TRXs can vary from site to site and that number determines the BTS configuration of that site.
BTS Configuration BTS supports the following cell configurations- Omni cell- One sector cell- Two sectors cell- Three sectors cell
BTS ConfigurationBTS configuration is presented as S1/1/1 where S means sector Above configuration shows that the BTS is sectored.It has 3 sectors and each sector has 1 TRX.S2/3/2 means BTS has 3 sectors.First sector has 2 TRXs, second sector has 3 TRXs and third sector has 2 TRXs
BTS ConfigurationBTS configuration can be S2 where the BTS is sectored with only one sector having only two TRXs.BTS configuration can be S3/3 where the BTS has two sectors with each sectors of 3 TRXs.
BTS ConfigurationOmnidirectinal BTS is presented as O2 where the BTS has only 2 TRX.Similarly O4 means the BTS is omnidirectional with 4 TRXs.O1 means omnidirectional BTS with only one TRX.
BTS ConfigurationSupports the omni directional and directional coverageCombination of two cabinets to form one group Combination of three cabinets to form a group.One single cabinet supports upto 12 TRXs in the full configuration.
Configuration PrincipleUse as few as possible cabinets for cell configurationsAll TRXs of a cell are configured in the same cabinetTRXs are configured in the basic cabinet in preference and the number of TRXs in the basic cabinet is not less than that in any extension cabinet
Configuration PrincipleIn full configuration, the BTS configuration will be O36 or S12/12/12.The Transmit power will be 40W or 80W.For 40W the maximum configuration is S12/12/12 or O36But for 80W BTS, additional modules called power amplifier (PA) are required so the capacity of the BTS decreases and BTS maximum configuration will be S6/6/6 or O18.
