Then in case of 2G Narrow Band Wireless Digital Network is used. Both the 1G and 2G deals with voice calls and has to utilize the maximum bandwidth as well as limited to sending messages i.e. SMS. In 3G Wide Band Wireless Network is used with which the clarity increases and gives the perfection as like that of a real conversation. In addition to verbal communication it includes data services, access to television/video, categorizing it into triple play service. 3G operates at 2100MHz and has a bandwidth of 1520MHz . -

This technological shift has caused a disruption in the industry and led to the demise of many incumbents as new firms entered the industry. We argue that the shift the mobile industry has gone through is not merely a technological one, but rather a paradigm shift from the old feature phone paradigm to the new smartphone paradigm. Further, this paradigm shift brings substantial changes; where the institutions and underlying logic as well as those competences and business models that are important differ between the two paradigms. -

History of Mobile Telephony MAS 490: Theory and Practice of Mobile Applications
History of Mobile Telephony MAS 490: Theory and Practice of Mobile Applications Professor John F. Clark Everything I know about mobile telephony, I learned from: Evolution is not a theory when it concerns cell phones Early History of Radiophones Nicola Tesla and Guglielmo Marconi were the founders of wireless technology Ship to shore radiotelegraphy employed wireless use of Morse Code Later, radiophones and radiotelephony transmitted speech In 1900 Reginald Fessenden invented early broadcasting, transatlantic two-way voice communication, and later television Tesla, Marconi, and Fessenden The Great Wireless Fiasco Early History of Radiophones In 1926 radiophones connected people traveling on trains in Europe A little later, they were introduced in planes, but this was too late for World War I Radiophones made a huge difference in WWII – planes, tanks, and field communication via backpack radios and walkie-talkies. Later, in the 1950s, radiophones made civil and commercial services possible Military Field Communications Civil Field Communications Civil Field Communications, pt. 2 Early History of Mobile Telephony The 60s and 70s saw a variety of commercial car services – the earliest weighed 90-100 pounds These services operated using high power transmissions The concept of low power transmission in hexagonal cells was introduced in 1947 The electronics were advanced enough by the 60s to pull it off, but there was no method for handoffs from one cell to the next High Power Mobile Phone Low Power Mobile Phone System Early History of Mobile Telephony That problem was solved with the first functioning cell system and first real cell phone call in 1973. The phone, which weighed about six pounds, was developed by Martin Cooper of Motorola Bell Labs and Motorola were the main competitors in the US. -
Motorola Micro Tac Classic
Motorola Micro Tac Classic Product: Motorola Micro Tac Classic Date of Design: 1992 Designer / Retailer: Motorola Cost 1992: - Cost 2007: £40 Retro Brick state… The Motorola MicroTAC phone set a new design standard for 1989 with a flip-lid mouthpiece. As the smallest and lightest phone on the market, the unit weighed 12.3 ounces, measured 6.75 x 2.25 x 1.25 inches and retailed between £1,200 and £1,800… ouch. This phone is actually third generation of this particular design and was launched in 1991/2 ‘This was a whole new direction for Motorola. New technological advances meant that the equipment could be radically downsized. And so began the quest to be the smallest, lightest and most portable. The original MicroTAC was a completely new design and was the first phone to use this radical flip. There are also few things about it which are quite unusual.... The small hole in the front of the flip gave you the impression that there was a microphone in the flip which was positioned directly in front of your mouth, however, the microphone is actually situated just behind a tiny hole in the main part of the phone just between the right hand hinge and the call end button on the bottom right. Another puzzling design feature was the retractable aerial. In fact, the aerial does absolutely nothing as it is purely for show. The unit features an internal antenna, however, the pull up plastic was added after focus groups in the US felt that any phone should have a visible aerial. -

IMS - Mobile Server Platform The foundation of Mobile-to-Mobile service networks for future cellular Systems Von der Fakult¨atf¨urMathematik, Informatik und Naturwissenschaften der RWTH Aachen University zur Erlangung des akademischen Grades eines Doktors der Naturwissenschaften genehmigte Dissertation vorgelegt von M.Sc. Muzzamil Aziz aus Kuwait City, Kuwait Berichter: Universit¨atsprofessorDr. rer. pol. Matthias Jarke Universit¨atsprofessorDr.-Ing. Bernhard Walke Tag der m¨undlichen Pr¨ufung:9. Feb 2017 Diese Dissertation ist auf den Internetseiten der Universit¨atsbibliothekonline verf¨ugbar \He grants wisdom to whom He pleases, and whoever is granted wisdom, he indeed is given a great good and none but men of understanding mind." Quran: Chapter 2, Verse 269 Abstract The unprecedented growth of mobile application market is the evidence of twofold technological advancement in the wireless world: first, the enormous increase in the capacity of mobile networks and second, the rapid increase in the computing powers of mobile devices. The former has enabled the network operators to ensure quality of service on their network by inducing more capacity for seamless data transmissions. Whereas, the latter has contributed in the novel space of mobile server paradigm, where the mobile devices are assumed to have sufficient computing power of hosting and distributing small and medium-sized data services among the peers on the network. Nevertheless, considering the mobile server paradigm or peer-to-peer mobile applications, the availability of such applications are mostly limited to WiFi and Wireless Local Area Networks (WLAN) only and, hence, not available for cellular data networks. There are various technical and political reasons behind this phenomena. -
History of Mobile Phones
History of mobile phones The history of mobile phones begins with early efforts to develop mobile telephony concepts using two-way radios and continues through emergence of modern mobile phones and associated services. Radiophones have a long and varied history going back to Reginald Fessenden's invention and shore-to-ship demonstration of radio telephony, through the Second World War with military use of radio telephony links and civil services in the 1950s, while hand-held mobile radio devices have been available since 1973. Mobile phone history is often divided into generations (first, second, third and so on) to mark significant step changes in capabilities as the technology improved over the years. In Europe, radio telephony was first used on the first-class passenger trains between Berlin and Hamburg in 1926. At the same time, radio telephony was introduced on passenger airplanes for air traffic security. Later radio telephony was introduced on a large scale in German tanks during the Second World War. In all of these cases the service was confined to specialists that were trained to use the equipment. In the early 1950s ships on the Rhine were among the first to use radio telephony with an untrained end customer as a user. However it was the 1940s onwards that saw the . Motorola developed a backpacked two-way radio, the Walkie-Talkie and a large hand-held two-way radio for the US military. This battery powered "Handie-Talkie" (HT) was about the size of a man's forearm. In 1946 in St. Louis, the Mobile Telephone Service was introduced In 1964 Improved Mobile Telephone Service was introduced with additional channels and more automatic handling of calls to the public switched telephone network. -

Printed in the United States Recruiter Fundamentals : System Architectures Overview Once seen as a fashionable device, the mobile phone has become one of the fastest growing technologies to date. They have become so engrained into our daily lives that we no longer see mobile phones as a piece of technology, but as a necessity we cannot live without. In the beginning, the early mobile phones were bulky, heavy, and didn't hold a good charge. These phones were predominately used for making and receiving calls, but through breakthroughs in technology, the current landscape of mobile phones evolved into something more: a smartphone. These new smartphones have more functionality than the traditional mobile ones. The newer smartphone changed from being just a phone into the equivalent of a small, pocket sized, computer. These devices can now host various types of applications that can be used for business and personal tasks. -

"Cell Phone" redirects here. For the film, see Cell Phone (film). For the Handphone film, see Handphone (film). The Galaxy Nexus, an example of a smartphone A mobile phone (also known as a cellular phone, cell phone and a hand phone) is a device that can make and receive telephone calls over a radio link whilst moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station. In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these and more general computing capabilities are referred to as smartphones. The first hand-held mobile phone was demonstrated by Dr Martin Cooper of Motorola in 1973, using a handset weighing around 1 kg.[1] In 1983, theDynaTAC 8000x was the first to be commercially available. In the twenty years from 1990 to 2011, worldwide mobile phone subscriptions grew from 12.4 million to over 5.6 billion, penetrating the developing economies and reaching the bottom of the economic pyramid.

The term “mobile” has historically been used to classify all radio terminal that could be moved during operation. More recently, use “mobile” to describe a radio terminal that is attached to a high speed mobile platform e.g., a cellular telephone in a fast moving vehicle use “portable” to describes a radio terminal that can be hand- held and used by someone at walking speed e.g., a walkie-talkie or cordless telephone inside a home 6 [Rappaport, 2002, p 9] [Goldsmith, 2005, Section 1.1] History (1) The first wireless networks were developed in the pre- industrial age. These systems transmitted information over line-of-sight distances (later extended by telescopes) using smoke signals, torch signaling, flashing mirrors, signal flares, or semaphore flags. 7 Semaphore 8 History: Radio Early communication networks were replaced first by the telegraph network (invented by Samuel Morse in 1838) and later by the telephone.

The Symbiotic Relationship Between App Developers and Platforms: a Ten-Year Retrospective Preface
The Symbiotic Relationship Between App Developers and Platforms: A Ten-Year Retrospective Preface It is often easy to forget the journey once we arrive at the destination. We forget the bumps in the road and often overlook factors that made the trip possible. The app economy’s trajectory is no different. In nearly a decade of existence, the app ecosystem has grown exponentially alongside the rise of the smartphone. Valued at $950 billion,i the app economy is driven by app developers and innovators who depend on platforms like Apple’s App Store to reach consumers around the globe. In 2017 alone, 3.4 billion people spent 1.6 trillion hours using apps across a variety of platforms,ii and the reach of software applications continues to grow. This paper offers a look at the journey and the symbiotic relationship between app developers and platforms that drive the app economy. I. Introduction Much has changed for consumers and developers since the early days of software applications. In the early 1990s, consumers were tasked with the challenge of locating and then traveling to a brick-and-mortar store that happened to sell software. Once internet connectivity became a standard feature in most private residences, consumers began to download applications from the comfort of their homes without having to step foot in a physical store. Still, the golden age of PC software pales in comparison to the size and scale of the mobile app revolution during which software developers evolved into app developers. Today, software titles in Apple’s App Store for iOS and Mac exceed 1.5 million.iii Before the ubiquity of mobile platforms, the software ecosystem ran on personal computers.
