gsm 900 less base stations compared to 1800, gsm 1800 more capacity compared to 900 in terms of traffic hence less congestion.
GSM900 transmitted power from BTS: 39dBm GSM1800 transmitted power from BTS: 36dBm
GSM900 holds more subscribers than GSM1800 because of the lower frequency needed to transmit signals. Information from base station to mobile station and vice versa is lower for GSM900 compared to GSM1800. So there is more coverage even in rural areas, contributing more subscribers.
Scientifically it is proved that The higher you go in the GSM number, the lesser the wavelength. Therefore GSM900 Is preferred than Gsm1800. But 3G uses 2100 what is the reason?
No, Malaysia only operate on GSM900, 1800,1900 and 3G
Two UK mobile phone networks (T-Mobile and Orange) use a standard known as GSM1800. This uses a frequency of about 1800MHz.Two UK mobile phone networks (O2 and Vodafone) use a standard known as GSM900. This uses a frequency of about 900MHz.
Uplink --> 890 MHz - 915 MHz Downlink --> 935 MHz - 960 MHz
174 no ........ the uplink is 890-915 & down link is 935-960.....MHz each channel having band width of 200KHz & using by 8 subsciber.... so 25MHz/200Khz ......=125...so there are 125 channels present in GSM900 but one channel is use as a guard so only 124 channel present in GSM900
