1. Global System for Mobile communication (GSM) :
It is a mobile network widely used by mobile phone users in 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 in order to validate the handset.
Difference between GSM and LTE :
|1.||GSM supports both voice calls and data.||Whereas it is used only for high speed data communication.|
|2.||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)|
|3.||In CSM, information is transported through channels that are separated into physical and logical channels.||Whereas in LTE, information is carried using physical, logical and transport channels.|
|4.||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.|
|5.||In this, the information of customer is stored in sim card.||Whereas in this, a sim card is required to verify the mobile phone.|
|6.||It is comparatively slow network.||Whereas it is the fastest network.|
