i think 8-psk modulation is also used..... for edge hardware.
Well the reason GMSK is used for GSM.1. High spectral Efficiency2. Since Basic MSK uses Phase variations for modulation so better immune to noise.3.Use of non-linear amplifiers at receivers can be utilized since the information is stored in phase variations rather than amplitude, Non-linear amplifiers give better response and consume less power so low battery usage which is a important parameter in Cellular technology.
GMSK (Gaussian minimum shift keying) is used for GSM (Global System for Mobile Communications) because it provides a good balance between spectral efficiency, power efficiency, and robustness against noise and interference. It also allows for efficient use of the available frequency spectrum in mobile communication systems.
¢obviously the improved spectral efficiency when compared to other phase shift keyed modes
¢can be amplified by a non-linear amplifier and remain undistorted
¢none of the information is carried as amplitude variations.
¢GMSK also produces less noise when compared with other phase shift-keying modulation schemes.

What Type of modulation used in GSM?
GSM uses Gaussian Minimum Shift Keying (GMSK) modulation for its radio interface. GMSK is a form of continuous-phase frequency shift keying that helps in reducing interference, improving spectral efficiency, and providing better resistance to multipath fading.
Gsm 900 vs gsm 1800?
GSM 900 operates at a frequency of 900 MHz, providing better coverage in rural areas due to its longer wavelength. GSM 1800 operates at a frequency of 1800 MHz, offering higher capacity and faster data speeds in urban areas. The choice between GSM 900 and GSM 1800 depends on the population density and geographic area where the service will be provided.
How do you calculate gsm of polyethylene?
To calculate the GSM (grams per square meter) of polyethylene, you need to know the weight in grams of a known area of the material. Measure a specific area of the polyethylene sample, weigh it in grams, and then divide the weight by the area measured to determine the GSM. The formula for calculating GSM is GSM = (Weight in grams / Area in square meters).
How secure is the GSM cell phone network?
The telephone company GSM provide a range of phone network services. The use of a SIM card in GSM allows users to maintain a high-level of security, particularly of personal data.
How many GSM in 1 micron?
There are 1000 nanometers in 1 micron. The GSM (grams per square meter) measurement is commonly used to measure the weight or density of paper or fabric. The GSM is not directly related to the size in microns.
Which modulation technique is used in gsm?
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
What Type of modulation used in GSM?

What Spectral efficiency means related to GMSK in GSM?
0.17 bit/s per Hertz per sector
What are the Uses of modulation techniques in telecommunication?
In GSM generally GMSK which is a derivative of MSK is beeing used because of its spectral efficiency and more noise resistant. Regards Sumeer Mehaboob
