There were radio telephone systems even before that 2G The second generation of digital mobile phone technologies including GSM, CDMA IS-95 and D-AMPS IS-136. first analog cellular systems, which started early 1980s. There were radio telephone systems even before that 2.5G The enhancement of GSM which includes technologies such as GPRS 3G The third generation of mobile phone technologies covered by the ITU IMT-2000 family Analysis of 1g & 2g: Analysis of 1g & 2g In 1G, narrow band analogue mobile network is used. This facilitates the voice calls and sending text messages. These services are provided with circuit switching. GSM is a globally accepted standard for digital cellular communications. GSM uses narrowband Time Division Multiple Access (TDMA) for voice and Short Messaging Service (SMS).Slide 4: Today the usual call starts from the beginning pulse to rate to the final rate. Then in case of 2G Narrow Band Wireless Digital Network is used. It brings more clarity to the conversation and both these circuit-switching model. Both the 1G and 2G deals with voice calls and has to utilize the maximum bandwidth as well as a limited till sending messages i.e. SMS. The latest technologies such as GPRS, is not available in these generations. But the greatest disadvantage as concerned to 1G is that with this we could contact with in the premises of that particular nation, where as in case of 2G the roaming facility a semi-global facility is available .GSM architecture: GSM architectureSlide 6: The added components of the GSM architecture include the functions of the databases and messaging systems: Home Location Register (HLR) Visitor Location Register (VLR) Equipment Identity Register (EIR) Authentication Center ( AuC ) SMS Serving Center (SMS SC) Gateway MSC (GMSC) Chargeback Center (CBC) Transcoder and Adaptation Unit (TRAU)UMTS(3G) : UMTS(3G) what is umts and why it is called so? Universal Mobile Telecommunications System (UMTS) is one of the third-generation (3G) mobile telecommunications technologies, which is also being developed into a 4G technology. The first deployment of the UMTS is the release99 (R99) architecture. ... Universal Mobile Telecommunications System So called 3rd generation mobile communications system which will provide enhanced range of multimedia services UMTS is the Western European name for the 3G The 3G follow on system to GSM that is standardised by ETSI under 3GPP. It uses Wideband CDMA (W-CDMA) with a 5 MHz channel bandwidth.Main features of umts(3G) : Main features of umts (3G) The features and services of 3G are as follows: With the help of 3G, we can access many new services like global roaming. 3G also have Wide Band Voice Channel, by this the world has been contracted to a little village because a person can contact with other person located in any part of the world and can even send messages too. Then the point to be noted is that 3G gives clarity of voice as well can talk with out any disturbance. In addition to that 3G also have entertainments such as Fast Communication, Internet, Mobile T.V, Video Conferencing , Video Calls, Multi Media Messaging Service (MMS), 3D gaming, Multi-Gaming etc are also available with 3G phones.Slide 9: 3G networks (UMTS FDD and TDD, CDMA2000 1x EVDO, CDMA2000 3x, TD-SCDMA, Arib WCDMA, EDGE, IMT-2000 DECT) are the latest cellular networks that have data rates 384 KB/s and more. The bandwidth and location information available to 3G devices gives rise to applications not previously available to mobile phone users. Some of the applications are: Mobile TV – a provider redirects a TV channel directly to the subscriber’s phone where it can be watched. Video on demand – a provider sends a movie to the subscriber’s phone. Video conferencing – subscribers can see as well as talk to each other. Tele-medicine – a medical provider monitors or provides advice to the potentially isolated subscriber. Location-based services – a provider sends localized weather or traffic conditions to the phone, or the phone allows the subscriber to find nearby businesses or friendumts architecture: umts architecture You do not have the permission to view this presentation.
