What is the maximum number of callers in each cell in a GSM?
As reuse factor is 7 in GSM, maximum number of callers in a cell is (124X8)\%7 = 141.
What is the bandwidth of GSM 900?
Frequency bands
| GSM band | ƒ (MHz) | Uplink (MHz) (mobile to base) |
|---|---|---|
| R-GSM-900 | 900 | 876.0 – 915.0 |
| T-GSM-900 | 900 | 870.4 – 876.0 |
| DCS-1800 | 1800 | 1710.2 – 1784.8 |
| PCS-1900 | 1900 | 1850.2 – 1909.8 |
What is the uplink frequency and downlink frequency for GSM 900?
Frequency Bands and ARFCN
| Frequency Band | Uplink/Downlink Separation | Downlink Frequency Range (Transmit Device = Base) |
|---|---|---|
| GSM 850 | 45 MHz | 869 to 894 MHz |
| P-GSM 900 | 45 MHz | 935 to 960 MHz |
| E-GSM 900 | 45 MHz | 925 to 960 MHz |
| R-GSM 900 | 45 MHz | 921 to 960 MHz |
What is the maximum number of callers in each cell in amps?
What is the maximum number of callers in each cell in AMPS? Reuse = 7, 416 channels per provider, 21 for control. What is the maximum number of simultaneous calls in each cell in an IS-136 (D-AMPS) system, assuming no analog control channels?
Why the size of the cell is kept small in cellular network?
Explanation: The size of the cells in cellular network is kept small because of the need of high capacity in areas with high user density and reduced size and cost of base station electronics.
What is the maximum channel bandwidth of GSM system?
The channel data rate for all 8 channels is 270.833 kbit/s, and the frame duration is 4.615 ms. The transmission power in the handset is limited to a maximum of 2 watts in GSM 850/900 and 1 watt in GSM 1800/1900.
How is bandwidth increased in Cdma2000?
How is bandwidth increased in Cdma2000? Explanation: The increase in the bandwidth is achieved through clubbing the adjacent radio channels of CdmaOne and using multicarrier technologies. For example, Cdma2000 3xRTT uses these technologies by combining three adjacent 1.25 MHz bandwidth of CdmaOne channels.
What is the frequency range of the GSM-900?
GSM-900 uses 890 – 915 MHz to send information from the Mobile Station to the Base Transceiver Station (uplink) and 935 – 960 MHz for the other direction (downlink), providing 124 RF channels (channel numbers 1 to 124) spaced at 200 kHz. Duplex spacing of 45 MHz is used.
What is the duplex spacing between GSM 1800 and 900 MHz?
Duplex spacing is 95 MHz. GSM-1800 is also called PCS in Hong Kong and the United Kingdom. Most of the GSM operators in India use the 900 MHz band. Operators like Hutch, Airtel, Idea, and some others, use 900MHz in rural areas and 1800MHz in urban areas.
How is the output power of GSM networks recorded?
The GSM network controls the output power used by any connected mobile phone, and it is possible to record this information using dedicated software. The output power for all mobile phone calls managed by the operator Telia Mobile GSM in the defined geographic areas was recorded during one week in September 2001 (week 37).
What is the difference between GSM-900 and E-GSM?
GSM-900 and GSM-1800. In some countries the GSM-900 band has been extended to cover a larger frequency range. This ‘extended GSM’, E-GSM, uses frequency range 880 – 915 MHz (uplink) and 925 – 960 MHz (downlink), adding 50 channels (channel numbers 975 to 1023 and 0) to the original GSM-900 band.
