(around 700mb) in under a moment at a normal rate of 20 mbps. 4g has seen different advancements and various innovation upgrades, from beginning with original to advance to Second era amid which we first saw show of exchange pace surpassing 64 kbps, 2g was advanced by Third Generation of portable correspondence with its exchange velocities of 2 mbps. As time advanced we saw presentation of fourth

one further step to 3G technology networks. wireless service providers are upgraded the 2G networks to 2.5 networks because of the subscribers demand and the 2G architecture remains same to give better voice and data applications. Many users will not wait until the final 3G technology so that in 2.5 G like IS-54 , IS -136 , IS-95 , IS-95A , IS - 95B technologies were launched. GPRS technology is a midway of 2G and 3G. It uses packet switching technique , by this mobile data is cheaper and faster

Threat of Substitution (High to Medium) Threat of substitution does exist for MediaTek because they are aimed at the 2G mobile phone market, thus consumers can switch at any time to the high-end 3G market. The 3G technology that is offered by many other companies allows consumers to have a much faster product without having to incur a huge price increase. With customers

The competitive landscape of the bioresorbable industry poses a threat for Synthes, as it's composed of big players, specialists, and potential entrants. The biggest threat is Johnson and Johnson, which has a strong sales force which comes them access to doctors and hospitals across the U.S. Furthermore, J&J is a major player in the sports medicine industry, where it takes full advantage of its 2nd generation of bioresorbable technology. Although, J&J is a threat in their ability to develop and market

keep seeking unrestricted communication at all time. Mobile telecommunication satisfied people's demand with the first generation (1G) and the second generation (2G). In the wake of development in multimedia and internet, most of telecommunication mobile networks operators have offered the third generation (3G) to the customers to replace 2G over the past two years. Currently, many ICT professionals and research

Abstract— 5G Technology stands for fifth Generation Mobile technology. From generation 1G to 2.5G and from 3G to 5G this world of telecommunication has seen a number of improvements along with improved performance with every passing day. This fast revolution in mobile computing changes our day to day life that is way we work, interact, learn etc. This paper also focuses on all preceding generations of mobile communication along with fifth generation technology. Fifth generation network provide affordable

9. RNC Site Solutions 9.1 Site connectivity solutions There are various options for connection of the RNC site to the rest of the operator’s network. In this study only the IP related options shall be studied, thus the only considered scenarios are layer 3 (routed, IP based) and layer 2 (switched, Ethernet) transport. 9.1.1 Layer 3 (routed) backbone and access network In case IP technology is used for both backbone and access transport the whole site connectivity (despite of PSTN and legacy TDM

server. In business and home applications, mobile users and in all social issues the networks are used . To enhance the benefits of these networks, we are introducing 3G systems. The aim of the 3G security architecture is to improve on the security of 2G systems.3G systems have additional standards like EDGE and CDMA rather than older systems. It has a high quality voice and video services but has limited in coverage area. Now introducing the 4G technologies to full fill the limitations of 3G.

1990s the (2G) networks came as a digital network comparing to the analog in (1G). That was the first digital cellular network after the switches that were supported digital calls by using actual 0s and 1s. The (2G) networks were supported by these standards D-AMPS, Code Division Multiple Access One (CDMAOne) and Global System of Mobile Communication (GSM). The second generation of telephony (2G) was offered a higher capacity, improved security and improved the voice quality. The (2G) technology
