## difference between GSM900, DCS1800 and PCS1900-GSM900, DCS1800, PCS1900

This page compares GSM900 vs DCS1800 vs PCS1900 and mentions difference between GSM900, DCS1800 and PCS1900.

Specification GSM900 DCS1800 PCS1900
925.4 to 935 MHz(extended band)
1805 to 1880 MHz 1930 to 1989.6 MHz
Uplink Frequencies 890.2 to 915 MHz
880.4 to 890 MHz(extended band)
1710 to 1785 MHz 1850 to 1909.6 MHz
Channel numbers and number of available channels 1 to 124 = 124 channels
975 to 1023 =49 channels(extended band)
512 to 885 = 374 channels 512 to 810 = 299 channels
Formula to convert frequency and channel number-Downlink n = ARFCN = 1-124
F(DL)=(935.2+0.2*(n-1)) MHz
n=ARFCN = 512-885
F(DL)= (1805.2 + 0.2*(n-512)) MHz
n=ARFCN=512-810
F(DL) = 1930 + 0.2* (n-512) MHz
Formula to convert frequency and channel number-Uplink F(UL)= (890.2+ 0.2*(n-1)) MHz F(UL)= (1710.2+0.2*(n-512)) MHz F(UL)= (1850.2+0.2*(n-512)) MHz
Formula to convert frequency and channel number-Extended Band-Downlink F(DL)= (935.2+0.2*(n-1024)) MHz - -
Formula to convert frequency and channel number-Extended Band-Uplink F(UL)= (890.2+0.2*(n-1024)) - -
