1. Global System for Mobile communication (GSM): It is a mobile network widely used by mobile phone users around the world. In this, the information of the customer is put on a sim card that can be carried in the new mobile handset. It is operated on either 900 MHz or 1, 800 MHz frequency band. In GSM, two technologies are used which are: FDMA and TDMA. 

2. Long Term Evolution (LTE): It is a standard for high-speed data communication. It delivers download speeds of around 100 Mbps and upload speeds of around 50 Mbps. It does not deliver good voice call quality while using the data services. It needs a sim card to validate the handset. 

Difference between GSM and LTE :

1. 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.

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).

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.
