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 |
---|---|---|---|
Downlink Fequencies | 935.2 to 960MHz 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)) | - | - |
