In today’s world, smart phones play an important role for many people and businesses. People use smart phones because it allows them to do many tasks on the go, checking e-mail, viewing bank statements and balances even social networking. For many it has also become a status symbol. To own the latest iPhone or Android is no longer about just function, many of the phones features are never even understood or used. It is about the bragging rights. To stand amongst your friends and family and hold up the shiny new phone and feel superior. The real question though, is are these new phones really better for us, or are they making us better targets for identity theft, privacy invasion and hacking attempts.

There have been several changes to phone technology since the cell phone was invented in the 1970’s and used the analog system of sending information. The analog system was unencrypted and could be intercepted by anyone with common electronic devices available at Radio Shack. Next was iDen (Integrated Digital Enhanced Network), which used digital waves instead of analog. It has evolved into what we know now as Nextel’s Push-to-Talk feature. More secure than analog, but still easy to intercept and decode. TDMA (Time Division Media Access) was implemented by AT&T in the 1990’s. It featured a voice security that enabled encryption on your phone based on your voice. However if you enabled it, your phone would not work because AT&T never installed the software on their servers.

GMS (Global System Mobile, recently renamed Global System for Mobile Communications) is the current leading system used in the world today. It uses a smart chip or SIM card that stores your data and information and can be transferred between phones. This system uses a digital encryption between your phone and the base tower, and then sends the information over the providers…...

...--->Just a couple of years ago the biggest software concern we had about our cellphone was whether or not it could play Snakes. Today, smartphones have become a popular target among hackers and malware producers. It is a high-reward business because most people are unaware that their cellphone is just as vulnerable to cyber attacks as their desktop computer. Think about all of the things that you do on your cellphone, and then imagine a worst case scenario we can keep our cellphones, and our data, safe. ---->The most obvious threat to the security of our smartphones is simply for the device to falls into the wrong hands. As silly as this sound, most cases of smartphone data theft begins with a lost or stolen phone. The first line of defense is common sense. Don't put your phone down in a public place, and don't leave it where it is easily grabbed. In short, treat your phone as you would your wallet. In case your phone does get snatched by a passing evildoer, the next step is to make sure that you have a secure screen lock. For Blackberry, iOS and Windows phones use a secure password. Something that's easily remembered, but not easily guessed. If it includes personal information such as your name, birthday or address it is not safe. For Android users, make sure that your unlock pattern is relatively complex and crosses over itself. If not, somebody can deduce your pattern from the repeated smudge marks on your screen....

Zealand context, Samsung has positioned themselves as a high- tech Smartphone provider, catering to a younger generation, with a considerable amount of technical ability, this is illustrated by their advertising campaign which shows people queuing outside a store for the launch of the new Iphone, a large proportion of the people queuing are of the baby boomer generation and those who aren’t watch people passing by with the Samsung galaxy s3 and become jealous of its features. The ad closes with the tag line “the next big thing is already here”, this ad is showing that Samsung believes that their product is “better” than the Iphone and also suited to a younger and more capable generation.

... hit television was the Smart TV. The smart TV is the ultimate multi-media convergence. These televisions combine TV with the Internet. Smart TVs allow people to surf the web, stream videos and use services such as YouTube, Netflix and Hulu Plus. Internet radio and services such as Pandora, Rhapsody and social networking sites like Facebook and Instagram can be accessed. Games and apps that can be downloaded to the smart phone are also available. Smart TVs are also typically DLNA certified, enabling the sharing of movies, photos, music and similar multimedia content from other DLNA-compliant PCs, tablets, smart phones and similar devices. Television has always been considered media convergence. Medias such as news, radio, film and music can all be accessed via television. Cable stations have channels that only play music. There also cable channels such as STARZ that only plays films. Networks such as CNN and FOX News only report news 24hours a day. All these forms of media can be accessed by clicking on the television. Now that the Smart TV has been created the media convergence has moved into a whole new realm. Research shows that there are a rising number of TV viewers are surfing the internet while watching television. This provides an avenue for social interaction with people talking about TV shows as they are watching them. Shows such as “Dancing with the Stars” and “American Idol”, are made specifically for this medium. Audiences watch and then go online or...

Smart Phone Advertising

...The music was pumping and the finger food laid out in abundance one recent evening in a subterranean Manhattan bar, as executives of Pandora Media, the Internet radio service, mingled with some of their most prized new advertisers. Most of the clients, however, were not representing big corporate accounts or multimillion-dollar national campaigns, but rather local businesses whose budget might top off at $20,000 a month. Yet they are the focus of one of Pandora's most important new corporate strategies as it competes with terrestrial broadcasters for a chunk of radio's $17 billion ad market. Pandora's pitch to advertisers is that its technology can cater to consumers with far greater precision than radio -- it can pinpoint listeners by age and sex, ZIP code or even musical taste -- and that as it grows, Pandora will effectively be the top station in many cities. ''A dollar spent on Pandora is better than a dollar spent on terrestrial radio,'' said Tim Westergren, the company's founder and chief strategy officer, nearly shouting at a corner table to be heard above the din of his party. Competing head-to-head with terrestrial radio's armies of local sales staff members will not be easy. But for Pandora, increasing ad revenue is essential. The service went online in 2005, streaming free music tailored to listeners' tastes, and its growth has been explosive. In the last two years, it has gone from 45 million to 125 million registered users, and its revenue has...

...Why use a smart phone? Why use a smart phone ? Everybody has a cell phone and the majority of us have a smart phone. Smart phone plays an important role in our daily life. You can see whenever in the street or metro, millions of people use smart phone. Why smart phones so popular around the world? I will start my topic now, why use a smart phone? It is universally acknowledged that we can use a smart phone not only chat or text with others but also play games, read books, listen to the music, surf on the internet. Sometimes we can even say that smart phone is a small computer. Obviously, we use smart phone as an entertainment tool. Firstly, smart phone can be used as an audio player. It can provide you the music whenever you want , like everyday in the metro, music is necessary for me. Secondly, a smart phone sometimes can be instead of e-book. Although I think that E-book is popular nowadays, you don’t need to buy it if you have a smart phone. In addition, downloading books in phones instead of buying books in stores also means that you are an environmentally friendly person. Simultaneously, many games are free to access if you are tired from work or study. Finally, smart phones can be used in different ways so in my opinion, using a smart phone as an entertainment tool can make our life becomes simple and colorful.  Do smart phones have bad effects on our study? No way! I know that many people have an IPHONE as someone asked last week. For me as an example, I use...

Smart Cities

...Smart Cities will be the biggest enabler of Internet of Things Before going on and on about the mentioned subject, a question must be answered. What is a smart city? A smart city is a city where modern technologies and advanced resources are used to uplift the standard of living with the society. The target is achieved with better resource management and adapting methods that are more in accordance with the environment. A smart city is a city which has lower levels of pollution and other adverse effects on the biosphere and environment around it. It might sound something of similitude from science fiction of some perfect utopian future where robots serve as personal comfort assistants of the Human race, people travelling in flying cars or any such levitated contraptions and where we have trade relations with beings from another part of the Universe. To the contrary of the previous sentence, smart cities are not a part of a distant utopian future, but are happening now and the World Wide Web of the Internet has been the greatest tool in achieving it. In fact there are examples of Smart cities in the past such as Bletchley Park, where Professor Alan Turing deciphered the infamous Nazi cipher Enigma machine during World War II. Alan Turing who is often called the father of modern computing, is only fitting that he too once lived in a smart city that changed the course of history and we know and live now. Compared to the early 21st century, our way of living, at least in the...

Markting Based Smart Phone

... impact communication medium, that can be received by almost all mobile phone users. Several companies are adopting highly innovative m-commerce strategies using SMS text messaging. 15 billion SMS messages (Cyberatlas 2001a) were sent over GSM (Global System for Mobile Communications) wireless networks during December 2000. It is predicted that worldwide, within three years, there will be 100 billion SMS messages per month, this equates to three SMS messages per day, per mobile phone user. Reuters (Haywood 2000) calculates current annual growth rate at 1000%. Durlacher (Muller- Veërse 2000) estimates that around 90% of current SMS volume is person-to-person, with information services, email notification, SMS chat and distribution of ring tones accounting for the remaining 10%. This paper explores the marketing potential of business-to-consumer SMS. Rettie, Brum CONCEPTUAL FRAMEWORK M-Commerce The Durlacher M-Commerce Survey, (Muller-Veërse 2000) claims that European mcommerce is two years ahead of the US, and forecasts a value of €23,600m (approx $21bn) by the year 2003. More conservatively, for 2003, Jupiter projects that worldwide advertising, commerce and subscription revenue from mobile phones will only reach $7.5bn, (Jupiter Media Metrix cited by Cyberatlas 2001b). Worldwide predictions for 2005 vary widely from $64.4bn (Frost and Sullivan), to $210.8bn (Ovum) to $1,800bn (Gartner), (all cited in Haywood 2000). Durlacher predicts that mobile......

Also Apple can use the Away from competitors strategy, since iPhone has some unique features in it which is not available in some of the other smart phones, hence iPhone can be positioned away from its competitors. PRICING STRATEGIES Setting price is the part of the marketing mix that can generate revenue. Therefore, for effective marketing, setting the right price is very important. And this is the variable that can be changed most quickly in response to competitors price change. As a pricing policy, Apple can use skimming, penetration or offering a better value for money. But skimming pricing policy might not work for all countries in the Southeast Asia since there are many cost conscious customers at Southeast Asia compared to the Europe. Therefore Apple needs to reduce the price of the iPhone. Nevertheless, we can’t say that all countries will have cost conscious customers. There will be customers who will be willing to buy these iPhones at high prices once they understand the amazing features of this device. So therefore one of our pricing strategies includes charging a reasonable price for the iPhone, thus offering a better value for money. Apple can follow product mix pricing strategies such as optional product pricing which......
