What is channel spacing in GSM?
What is channel spacing in GSM?
200 kHz
The channel spacing for GSM is 200 kHz.
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 carrier spacing in GSM-900 DCS 1800?
GSM-900 and GSM-1800 are used in most of the world. GSM-900 uses 890 – 915 MHz to send information from the Mobile Station to the Base Transceiver Station (BTS) (This is the “uplink”) and 935 – 960 MHz for the other direction (downlink), providing 124 RF channels spaced at 200 kHz. Duplex spacing of 45 MHz is used.
Which frequency band supports more coverage area in GSM?
Online Test
| 33. | Which frequency band supports more coverage area in a GSM or 2G network? |
|---|---|
| a. | 1900MHz |
| b. | 1800MHz |
| c. | 900MHz |
| d. | None of the above |
What is the range of GSM?
Frequency Band The uplink frequency range specified for GSM is 933 – 960 MHz (basic 900 MHz band only). The downlink frequency band 890 – 915 MHz (basic 900 MHz band only).
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.
What is the main difference between GSM-900 and GSM 1800?
The two types of cellular telephony radiation use different carrier frequencies and give different frequency spectra, but they usually also differ in intensity, as GSM 900 MHz antennas operate at about double the power output than the corresponding DCS 1800 MHz ones.
What band is 900 MHz?
The 33-centimeter or 900 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio on a secondary basis. It ranges from 902 to 928 MHz and is unique to ITU Region 2. It is primarily used for very local communications as opposed to bands lower in frequency.
What is the uplink and downlink frequency in GSM-900 frequency band?
As mentioned earlier, GSM 900 was the first GSM system to be deployed, and uses a 25 MHz frequency band (935–960 MHz) in the downlink and another 25 MHz frequency band (890–915 MHz) in the uplink direction (Figure 7.1). The uplink and downlink bands are separated by 45 MHz.
