I would like to know why the Base station transmits higher frequencies
a)when the power required to transmit higher frequencies is more.
b)Higher the frequency shorter is the distance travelled by the wave.
Thanks and Regards

The power saving should be at the mobile station. While the base station aims at low interference (high signal quality) they use higher frequencies.

can some1 help me out in knowing the Uplink and downlink frequencies of GSM 1800.
chachu.14th February 2004 at 10:55 #36977ManuGuest
Uplink 824-849 Mhz
Downlink 869-894 Mhz14th February 2004 at 18:23 #36978Assem Asa’dGuest
Reference to your first reply about the question of our friend Madan, It is Ok that the power saving should be at the mobile station due to its low power budget while the base station has a reliable and continuous power resources, but the question is what is the relation between signal quality and the frequency if it is higher or lower.
Thanks in Advance

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

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 .20th March 2004 at 13:34 #36981akshayGuest
i miss typed the downlink frequency. it is 935- 960 Mhz25th March 2004 at 19:07 #36982ScotGuest
890-915 & 935-960 is GSM 900 Band.
What about CDMA in India ?

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
