for any gsm network you must study the loaded traffic which will be applied on this cell(how many subscribers will talk at the pic power and this measres known by erlangs,and this mission for cell planing group so check for cell planing manuals to calculate how many subscriber will use this sites to consider the size and kind of site needed as macro,micro and pico sites to make hierarashical coverage foe whole area to get best performance

hey guys, Do you guys know how to design a base station grid for GSM 900 system.

consider an urban area(small to medium city) having a rectangular shape of length 30km and width 25km. if the available base stations have their radiating powers 3w each, the antenna masts are 30m high, the antennas are omnidirectional, and have their gains of 2dB. assuming that mobile antennas are elevated to 1.5m, and have a gain of 0dB. Assume also that minimum signal strenght is -90dB.

hi all
the GSM 900 frequency is:
uplink is 890-915 MHZ
DOWN LINK IS 935-960
GSM (DCS)1800 frequency is:
up link 1710-1785MHZ.
down link is 1805-1880 MHZ.
gsm(PCS) 1900 frequency:
up link 1815-1910 MHZ
down link 1930-1990 MHZ

890-915 & 935-960 is GSM 900 Band.

What about CDMA in India ?

i miss typed the downlink frequency. it is 935- 960 Mhz

akshay - 20th March 2004  (11:56 GMT)

base station transmit at down link ferquency band of930--960mhz because as u know higer the frequency lesser is the travelled distance.so in case of base station we can transmit at higer power and at higer frequency.
,while ms(mobile station )should be transmitting at lower frequency band ie---890--915Mhz(uplink) Mhz so it is more easy for mobile station to transmit to the base transiever station at lower power and that will consume less battery power .

Scot - 19th March 2004  (18:24 GMT)

What is the frequency band used in India for CDMA ?
Other than 800 MHZ Band is there is any other bands ( standard )?
