As far as I know, India uses S-band ranging around  1500Mhz. for their DTH(Direct To Home) satelite service.

For the record, S-band (IEEE) is considered between 2GHz and 4GHz. 1.5GHz is down in the L-band (IEEE). Frequencies below C-band are generally limited to terrestrial use. This chart may help:
Band Frequency range Origin of name
HF band 3 to 30 MHz High Frequency
VHF band 30 to 300 MHz Very High Frequency
UHF band 300 to 1000 MHz Ultra High Frequency
L band 1 to 2 GHz Long wave
S band 2 to 4 GHz Short wave
C band 4 to 8 GHz Compromise between S and X
X band 8 to 12 GHz Used in WW II for fire control, X for cross (as in crosshair)
Ku band 12 to 18 GHz Kurz-under
K band 18 to 27 GHz German Kurz (short)
Ka band 27 to 40 GHz Kurz-above
V band 40 to 75 GHz
W band 75 to 110 GHz
mm band 110 to 300 GHz

Thanks for the details. C band starts from 4 GHz.(actually we get as low as 3.5 Ghz as C band in satellite transmission). I will try to find the link to 1.5 Ghz as S band)

As specified, the list I posted is as published by IEEE. C-Band variations around the world include:
Band Transmit Frequency (GHz) Receive Frequency (GHz)
Standard C-Band   5.8506.425 3.6254.200
Extended C-Band 5.8506.725 3.4004.200
INSAT Super-Extended C-Band 6.7257.025                                         4.5004.800
Russian C-Band     5.9756.475 3.6504.150
LMI C-Band 5.72506.025 3.7004.000
