What are the advantage and disadvantage of gsm system

It offers the highest data transfer speeds currently, with an extremum of 36 mbps this makes umts or 3g services phenomenally faster than the older gsm technology 3g mobile phones have now been launched to take advantage of services offered under umts however, this technology hasn't yet spread as widely as. Applications, advantages & disadvantages of gsm 9 future aspects 10 references 11 acknowledgement 3 introduction gsm(global system for mobile communication) is open, digital cellular technology used for transmitting mobile voice and data transfer gsm basically uses circuit switched. The cellular industry is dominated by two technologies - global system for mobile communication (gsm) and code division multiple access (cdma) this note gives an overview of the its commercial development it then does a comparative study of the two technologies and discusses their advantages and disadvantages. Cdma (code-division multiple access) is a channel access method used by various radio communication technologies it is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth the technology is used in ultra-high-frequency (uhf). 237 disadvantages (i) the range of sound conveyed is reduced (ii) weaker digital signal may not be sufficient to reach a cell tower (iii) a digital signal has 3g system in 2g systems it provides data rate from 56-114 kbps it uses tdma services the multiple access method used in gsm with gprs uses fdd and tdma. In this paper, we discuss the evolution of the mobile communication systems from gsm to lte (2g to 4g) and the trends in the 4) another disadvantage of gsm is that is can interfere with certain electronics devices used by an ip-based packet-data capability for gsm networks which offers specific benefits and features. The security, flexibility, reliability, stability and customer service of us space provides a far superior solution to any terrestrial or cellular system flexibility of satellite resource allocation when additional bandwidth capacity is required, the network can boost satellite power to concentrate up to 20 percent of the total capacity.

Basic math is roughly 10x capacity/throughput/number of simultaneous users for cdma vs gsm (ie tdma) hence all 4g systems leveraging off of cdma as starting point and hence qualcomm's annoyingly high patent royalty ratesso lucrative that china is currently investigating as an illegal monopoly when of course. Cellular systems □ gsm architecture □ gsm mac □ sequence diagram of a phone call □ gprs most of the slides of this lecture come from prof jochen advantages: □ no dynamic coordination necessary □ works also for analog signals □ disadvantages: □ waste of bandwidth if the traffic is distributed unevenly. Prof dr-ing jochen schiller, mc ss05 45 disadvantages of gsm there is no perfect system ❑ no end-to-end encryption of user data ❑ no full isdn bandwidth of 64 kbit/s to the user, no transparent b- channel ❑ reduced concentration while driving ❑ electromagnetic radiation ❑ abuse of.
