people can make calls.
# it is some antennas that are connected with cables to a small room
called a shelter that contains the following equipment:
–BTS ..base Tran receiver station
–Microwave.
–Air condition (A/C)
–Fire Alarm Box.
–.Fire Sensor
–Temperature Sensor.
–Power Distribution Panel
–Batteries.
–Cable Tray
–Duct.
–DC Cables
–BIB Cables.
–DDF box
–RF cables.

BTS cabinets
Base Transceiver Station (BTS)
1.Consists of the radio transmitters, receivers and the antenna system required to provide the coverage area for one cell.
2.Converts the GSM radiosignals into a format that can be recognized by the BSC.
3.Records and passes to the BSC the periodic power measurement reports.
4.Performs the network end function for the ciphering/encryption process.
Power Distribution Panel
it is the box that contains all the circuit breakers of all the equipment in shelter from the lights to the bts
cabinet
Batteries
•The batteries work when the current (3 phase) is cut down so that BTS still provide coverage.
•The batteries is connected to the rectifier.
DDF BOX
•DDF box contain 5 krones which the wire is connected to.
The wires are
–the BIB cable which carry the E1 to the BTS cabinets
–The route cable which carry the E1 from the Krone of the link.
–The PIX cable which carry the alarms to the BTS cabinet.
•The wires must be connected good so it do it’s job.
•The wire must be moving in a proper way in the box.

CABLE TRAY
•The picture shows that the RF cables must be far from the DC cable from the BIB cable.
•The cables must be labeled so we can know from the look the where it come from and to where it is going.
•It is not acceptable that the cables comes cross to each other.
AIR CONDITION
•It is used to lower the temperature of the shelter and the equipment.
•The 2 a/c switch with each other so that no one is overloaded.
•Note: the a/c circuit breakers must be on when you leave the shelter.

MICROWAVE INDOOR STAND
•The stand contains the microwave link and it’s DDF.
•The link connect the site to the another site or to the BSC through the microwave dishes.
•The microwave stand must be connected good to the floor and must be connected to the main earth bar of the shelter.
DUCT
The duct is a plastic path that contains the PCM alarm cabe and the BIB cables that are going to the DDF box.

FIRE ALARM BOX
SENSOR
•There are 3 sensors
1 sensor for the door
2 sensor for temperature which are adjusted for the temperature we need
RECTIFIER
–It is used from AC 3 phase to DC .
–The batteries, the link and the BTS cabinet through circuit breakers.
