Mobile Radio Telephone, USA, Areas outside Cities 11 ICTmc 11 Reda 2008 Wireles Generations at a Glance 3 G: HSPA:High-Speed Packet Access is a collection of mobile telephony protocols that extend and improve the performance of existing UMTS protocols. Three standards, HSDPA, HSUPAand HSOPA, were established HSUPA provides improved up-link performance of up to 5.76 Mbit/s theoretically. In Singapore, Starhub announced a 1.9 Mbit/s HSUPA Service as part of its new MaxMobile plan in 1 Aug 2007 [1]. In Finland, Elisa announced on 30.8.2007 1.4 Mbit/s HSUPA to most large cities with plans to add the service to its whole 3G network within months 12 ICTmc 12 Reda 2008 Wireles Generations at a Glance 3 G: HSDPA High Speed Downlink Packet Access provides improved theoretical down-link performance of up to 14.4 Mbit/s. Existing deployments provide up to 7.2 Mbit/s in down-link. Up-link performance is a maximum of 384 kbit/s. 13 ICTmc 13 Reda 2008 Wireles Generations at a Glance 3 G: UMTS: Universal Mobile Telecommunications System is one of the third-generation (3G) cell phone technologies, which is also being developed into a 4G technology.

It is based on the IEEE 802.16 standard, which is also called WirelessMAN. 15 ICTmc 15 Reda 2008 Wireles Generations at a Glance LTE: •improve the UMTS mobile phone standard •improving efficiency, lowering costs, improving services, making use of new spectrum opportunities •ALLROUNDER !! •LTE: All-IP-Networks •MS, SDE !! 16 ICTmc 16 Reda 2008 Wireles Generations at a Glance 4 G: Traditional definition: Fourth-Generation Communications System (also known as Beyond 3G), is a term used to describe the next step in wireless communications. A 4G system will be able to provide a comprehensive IP solution where voice, data and streamed multimedia can be given to users on an "Anytime, Anywhere" basis, and at higher data rates than previous generations. There is no formal definition for what 4G is; however, there are certain objectives that are projected for 4G . 17 ICTmc 17 Reda 2008 Wireles Generations at a Glance 4 G: Traditional definition: Fourth-Generation Communications System (also known as Beyond 3G), is a term used to describe the next step in wireless communications.
