Title:TheTransitionTechnology:EDGEintheThirdGenerationofMobileCommunication
Abstract:
Thethirdgenerationofmobilecommunicationbroughtsignificantadvancementsindatatransmissionspeed,usheringinaneraofenhancedconnectivityandmobileInternet.Aspartofthisevolution,EnhancedDataratesforGSMEvolution(EDGE)emergedasacriticaltransitiontechnology,bridgingthegapbetween2Gand3Gnetworks.Thispaperaimstoexplorethefundamentals,benefits,andchallengesofEDGE,aswellasitsimpactonthetelecommunicationsindustryandthefutureofmobilecommunication.
1.Introduction:
