Comparison of Various Data

Technologies



What is LTE??y 3rd Generation Partnership Project working in

association with the European TelecommunicationsStandards Institute

y LTE was introduced after the outcome of GSM/EDGEand UMTS/HSPA network technologies

y It is marketed as 4G but as it is not fulfilling the IMTadvanced 4G (4th generation) requirements it is said

to be 3.9G Technology .y It is not backwards compatible with 3G systems but

LTE advanced is compatible and hence uses the samefrequency bands



Featuresy Downlink peak data rates up to 326 Mbps with 20

MHz bandwidth

y Uplink peak data rates up to 86.4 Mbps with 20 MHzbandwidth

y Operation in both TDD and FDD modes

y Reduced latency, up to 10 milliseconds (ms) round-trip

times between user equipment and the base station,and to less than 100 ms transition times from inactiveto active



4G/IMT-Advancedy International Mobile Telecommunications-Advanced

(IMT-Advanced) technology family of mobile wireless

services, which has been defined and recently ratifiedby the International Telecommunication Union (ITU).
