The channel spacing for GSM is 200 kHz.
What is GSM ARFCN?
In GSM cellular networks, an absolute radio-frequency channel number (ARFCN) is a code that specifies a pair of physical radio carriers used for transmission and reception in a land mobile radio system, one for the uplink signal and one for the downlink signal.
How do you calculate ARFCN 5G?
NR-ARFCNs for 5G new radio are defined in 3GPP specification 38.101-1 and 38.101-2….NR-ARFCN Calculation Example:
- N. REF-Offs = 0 (Because 2120 is with in the range of 0 – 3000 MHz)
- F. REF = 2120 MHz (Given Frequency)
- F. REF-Offs = 0 (Because 2120 is with in the range of 0 – 3000 MHz)
- ΔF. Global = 5KHz

What is the frequency symbol?
symbol f
Frequency is denoted by the symbol f, and is measured in hertz (Hz) – formerly called cycles per second (cps or c/s) – kilohertz (kHz), or megahertz (mHz). See diagrams under RADIO SPECTRUM, SIMPLE HARMONIC MOTION, SPECTRUM.
What is Arfcn in NR?
An Absolute Radio-Frequency Channel Number (ARFCN) is a code that specifies a pair of reference frequencies used for transmission and reception in radio system.
What is Arfcn in telecom?
What is BCCH frequency?
Frequency allocation to GSM channels Signalling channel category is referred as BCCH frequency and traffic channel category is referred as TCH frequency(non BCCH frequency). To serve the purpose each cell is assigned one BCCH frequency(ARFCN) in the downlink and one BCCH frequency in the uplink.
What is SSB frequency in 5G?
So, the bandwidth occupied by SSB = 240 * subcarrier spacing. For instance, 15 kHz SCS leads to 240*15 kHz = 3.6 MHz and 30 kHz SCS leads 240*30 kHz = 7.2 MHz and so on….5G NR: Synchronization Signal/PBCH block (SSB)
| NR Operating Band(s) | SS Block SCS | SS Block Bandwidth (20 RBs = 240 SCs) |
|---|---|---|
| n257, n258, n260 and n261 | 240 kHz | 57.6 MHz (= 240 * 240 kHz) |
How do you calculate center frequency?
The point of maximum output gain is generally the geometric mean of the two -3dB value between the lower and upper cut-off points and is called the “Centre Frequency” or “Resonant Peak” value ƒr. This geometric mean value is calculated as being ƒr 2 = ƒ(UPPER) x ƒ(LOWER).

What are the frequencies used in GSM radio frequency planning?
The frequencies used in GSM radio frequency planning are divided among different frequency groups. GSM uses re-use patterns of 4/12 and 3/9 in most of the GSM installations. 4/12 refers to 12 frequency groups and 4 base stations, which means available GSM network frequencies are divided into 12 frequency groups across 4 BS sites.
What is the difference between ARFCN and 45MHz?
F (Uplink)=890+0.2*n, where n varies as mentioned from 1 to 124 and is referred as ARFCN (Absolute Radio Frequency Channel Number). 45MHz is the referred as duplex spacing, which is the difference between uplink and downlink frequency channels.
