Typically one GSM BTS hardware can cover a few numbers. Also, some numbers can also be covered by more than one GSM BTS. Since one cell is covered by exactly one BTS, the cell id uniquely identified the concrete BTS.

Why is a rectifier needed for a GSM BTS?
This is bcoz we need -48V for Gsm BTS, -48 DC is used to control Fluctuation So the main function of this is 1) To convert AC to DC 2) To control overloading
How many bts can be connected to a single bsc?
Up to hundreds (Wikipedia). There are technical limits, but the GSM standard doesn't say something about a maximum.

Why you use feeder between BTS to GSM Antennae?
There may be something to this question that we're missing, but here's the answer to the obvious interpretation: The BTS equipment is typically housed either in a shelter (building) or else in a ground-mounted equipment cabinet. On the other hand, in order to achieve the design area coverage, the GSM antenna is typically on the roof or wall of a building, on a monopole, or on a tower, located several tens of meters above the ground level. The fundamental design of the entire system requires that the transmit RF from the BTS output be guided to the antenna, and also that the RF received by the antenna be guided for processing to the BTS receiver, both with as little RF loss as possible. The "feeder" ... also called 'transmission line' and implemented in either coaxial cable or waveguide ... is the means to accomplish the transfer of RF energy in both directions with low loss.
Why is the gsm 900 better than gsm 1800 and gsm 1900?
As the frequency increase its penetration power decreases.The signal travels a lesser distance.Hence for a perticular area more no of towers need to be erected in 1800/1900 than in 900MHZ for full coverage...Hence vodafone( 1800MHZ) has more towers per unit area than Idea Cellular ( 1800+900) ..... Band of 900 is from 890-915( uplink) 935-960Mhz( downlink).... Band of 1800 is from 1710-1785(uplink) and 1805-1880MHZ(Downlink).... Same property is followed here.....The uplink is lower ( MOBILE -BTS) than the downlink frequency (BTS-MOBILE)...so that this may help the uplink signal to travel futher without consuming much power...BTS due to its increased power ,has higher frequency to tavel the same distance....
Area code for texting English phones from America?
First of all, replace the leading 0 of a UK domestic mobile number with country code +44. For example, the mobile number 07700 900123 becomes +44 7700 900123. If you have a GSM mobile, enter the number in international format, beginning with +44. If you have a non-GSM mobile, replace the plus sign with the international access prefix 011.
Why GSM has to be Encrypted?
