It is a prominent wireless technology used to determine the cellular network protocol used in mobile phones. |
LTE refers to the next generation of wireless technology for the cellular mobile communication system. |
2. |
GSM supports both voice calls and data. |
Whereas it is used only for high speed data communication. |
3. |
GSM uses Frequency Division Multiple Access(FDMA) and Time-division multiple access(TDMA). |
Whereas it uses Orthogonal frequency division multiple access(OFDMA) and Single-carrier frequency division multiple access(SC-FDMA) |
4. |
In GSM, information is transported through channels that are separated into physical and logical channels. |
Whereas in LTE, information is carried out using physical, logical, and transport channels. |
5. |
GSM uses both the second-generation (also known as 2G) and third-generation (3G) communication standards. |
LTE only uses the fourth generation (4G). |
6. |
In GSM, two frequency bands are used 900 MHz and 1800 MHz. |
Whereas in LTE, frequency bands from 1 to 25 and from 33 to 41 are reserved for FDD( Frequency Division Duplex) and TDD(Time Division Duplex) respectively. |
7. |
In this, the information of the customer is stored in a sim card. |
Whereas in this, a sim card is required to verify the mobile phone. |
8. |
It is comparatively slow network. |
Whereas it is the fastest network. |
9. |
The GSM architecture consists of the following:-
- Base Station Subsystem (BSS)
- Core Network (CN)
- User Equipment (UE).
|
The fundamental elements in the Evolved Packet Core (EPC) LTE architecture of Release 8 are as follows:-
- NB (E-UTRAN Node B)
- eGW (access gateway)
- MME (Mobile Management Entity)
- UPE (User Plane Entity).
|
10. |
Modulation Method-
- Gaussian Minimum Shift Keying (GMSK)
|
Modulation Method-
- Quadrature Phase Shift Keying
- 16 QAM
- 64 QAM

11. |
ARFCN is GSM channel number. |
EARFCN is LTE channel number. |
12. |
It is used for voice calls, GPRS, and data communications, and it includes new capabilities including SAIC, VAMOS, and MSRD. |
It is designed for data calls and includes MIMO, carrier aggregation, beamforming, and enhanced release ten versions. |
13. |
GSM follows 2*2 MIMO advancement. |
LTE follows 8*8, 4*4 MIMO advancement. |
