...A mobile phone (also known as a wireless phone, cell phone, or cellular telephone[1]) is a very small portable radio telephone. The mobile phone can be used to communicate over long distances without wires. It works by communicating with a nearby base station (also called a "cell site") which connects it to the main phone network. As the mobile phone moves around, if the mobile phone gets too far away from the cell it is connected to, that cell sends a message to another cell to tell the new cell to take over the call. This is called a "hand off," and the call continues with the new cell the phone is connected to. The hand-off is done so well and carefully that the user will usually never even know that the call was transferred to another cell. As mobile phones became more popular, they began to cost less money, and more people could afford them. Monthly plans became available for rates as low as US$30 or US$40 a month. Cell phones have become so cheap to own that they have mostly replaced pay phones and phone booths except for urban areas with many people. In recent days, more and more mobile phones are considered as "smartphones". As well as making voice calls, they can be used as computers. History Mobile phones in the 1950s through 1970s were large and heavy, and most were built into cars. In the late 20th century technology improved so people could carry their phones easily. Although Dr. Martin Cooper from Motorola made the first call using a mobile phone in...

In addition to the standard voice function of a mobile phone, telephone, current mobile phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, gaming, Bluetooth, infrared, camera with video recorder and MMS for sending and receiving photos and video. Most current mobile phones connect to a cellular network of base stations (cell sites), which is in turn interconnected to the public switched telephone network (PSTN) (the exception is satellite phones). History In 1908, U.S. Patent 887,357 for a wireless telephone was issued in to Nathan B. Stubblefield of Murray, Kentucky. He applied this patent to "cave radio" telephones and not directly to cellular telephony as the term is currently understood. Cells for mobile phone base stations were invented in 1947 by Bell Labs engineers at AT&T and further developed by Bell Labs during the 1960s...

...Mobile Phones As everybody knows, mobile phones have become an essecial tool, which plays a big and important role in our daily lives. Nowadays, there is no doubt that everybody has one of them. But why are they such popular? Are they useful? To start with, humans were meant to be sociable and talk to each other, we need to get in touch with other people, so that’s probably why it is convenient for us to have mobile phones, because we can call other people who are even in another country at any time! Moreover, they are portable, so we can carry them everywhere. In addition, they enable us to do emergency calls. For example, imagine that you have suffered a car accident and there’s nobody on the road or if you see a crime taking place…, it’s very helpful to do an emergency call in these cases. Police can locate kidnappers using the victim’s mobile phones’ networks! Furthermore, you can do many things with them. For instance, you can listen to music, make photos, share documents, surf the Net and so on. Nevertheless, there isn’t any evidence to prove they are safe to use and they are believed to give out radioactive waves and scientists believe the radioactivity can cause health issues such as brain tumor or damage our ears. Apart from that, people become addicted to them. People tend to talk to other people through the mobile phone instead of talking to the people they are with in that moment and there’s no doubt this affect students, because they use them during lessons...

...new means of communication which have made our life so simple and easy going. Mobile phone can be seen as the most used present day phenomenon in this fast growing time. Mobile phone is a revolutionary step in the field of tele-communication. We had the days when the telephones only served the purpose of communication through sound. Mobile phone has completely changed the concept of the telephoning. Now a phone is not only a mere phone but it is a lot in itself. A mobile phone works on a unique networked system which needs no wiring, no fixation and no botheration. Originally it was used in cars, airlines, and passanger trains but increasingly it is becoming ubiquitous. It is basically low- power radio telephone. In this magical system calls go through radio transmitters that are located within small geographical unit which are known as cells. Since each cell's signals are too weak to interfere with those of other cells operating on the same frequencies and more channels can be used than would be possible with high power radio frequency transmission. Narrow-band frequency modulation (FM) is the most common mode of transmission, each message is assigned a carrier, unique to the cell from which it is transmitted. The cellular phone was first tested in 1978. The cellular market in Britain alone had grown at a rapid rate to 8.5 million users by 1997. In Japan it is as high as one mobile phone per ten people. However, when the number of cellulars users had increased many...

...One reason that face-to-face communication is better than newer methods is that it allows one person to see the facial expressions of another. When a person is talking about good news they usually smile and their eyes light up. Or when a person is having a serious conversation, their eyebrows are usually lower and they keep a straight face on while talking. Without these facial expressions it can be tricky to figure out a person’s meaning behind what he says. Another reason why face-to-face communication is important is that you can tell whether the person is telling the truth or not. When people communicate over the phone or through an email it is impossible to tell when a person is lying. But when it comes to personal communication it is not as easy to get away with a lie. Many people in business prefer this face-to-face method because it helps them to figure out if the person speaking is honest enough to go into business with. When it comes to face-to-face communication there is one more reasons why it is better than other method of communication. When a person is expressing feelings of love or sympathy, no other method of communication will express them perfectly. When a person is showing his/her love for someone, he/she must do it face-to-face so that the other party can see how much he/she mean what he/she says. Also when it comes to expressing sympathy for someone, using any other types of communication is just not enough. By calling someone or emailing him/her to express...

...Competition in the Mobile Phone Markets of the United States and Europe International Business Master's thesis Mika Husso 2011 Department of Management and International Business Aalto University School of Economics AALTO UNIVERSITY SCHOOL OF ECONOMICS Department of Management and International business Master’s thesis ABSTRACT ANALYSIS OF COMPETITION IN THE MOBILE PHONE MARKETS OF THE UNITED STATES AND EUROPE Competition in an economic context is a widely studied phenomenon with a significant body of accumulated research and theory. However, competition in the mobile phone industry, despite its prevalence in public discussion, has received significantly less attention in academic research. Within the international business (IB) context there are very few academic studies that seek to analyze and compare the different geographical mobile phone markets from the viewpoint of competition. This thesis examines competition in the mobile phone markets of the United States and Europe in light of interviews and secondary data covering years 2002 - 2011. The framework used for the analysis is founded on concepts drawn primarily from industrial organization (IO) economics, IB theory and microeconomics. The first part of the thesis gives an overview of the U.S. and European mobile phone markets and the second part focuses specifically on Nokia, its actions and performance on the U.S. market. The findings reveal that the U.S. and European mobile phone markets are fundamentally...

...The question of who doesn't own a phone does not apply not only in Kenya but in most parts of the world. This is a level of technological advancement which everybody had longed for. Communication of urgent information both locally and internationally can be done in a twinkle of an eye. By clicking buttons on your Smartphone, iphone or whichever kind of phone you have, lives are saved, business transacted and much more within a short time. Kudos to mobile discoverers for enhancing commutation. Unlike long ago when people planned to send a letter, a process which involved a number of steps like purchase of a foolscap, envelope and a journey to look for an already used postal stamp that was to be made new by using Colgate, a lot has changed. May I take this opportunity to formally thank Colgate for manufacturing a paste that turned out to be an eraser of rubber stamps. Don't be surprised to find that some of the employees of the company did the same. Back to the use of mobile phones at workplace. I write this from a personal experience and not out of imagination. And I'm certain that a number of you reading this article and many others globally identify with me.

...An econometric analysis of the impact of mobile Dr. Mahesh Uppal is the Director of Com First (India) Private Ltd, a consultancy specializing in policy, regulation, and strategy. Mamta is a researcher at the Indian Council for Research on International Economic Relations (ICRIER). 1. Summary During the past two decades, India has moved away from its former ‘command and control’ policies to become a marketbased economy. This process started in the mid-1980s and gathered substantial momentum at the beginning of the 1990s. The process of reform has continued in this decade with a further opening of the economy and the creation of regulatory institutions to oversee the march towards fully competitive markets. As a result of the liberalisation, GDP per capita has been rising by 7% annually, a rate that leads to its doubling in a decade. This contrasts with annual growth of GDP per capita of just 1% in the three decades from 1950 to 1980. Rapid growth turned India into the third largest economy in the world in 2006 (after the United States and China and just ahead of Japan when measured at purchasing power parities), accounting for nearly 7% of world GDP. 1 Although India’s growth rate has been among the highest in the world, it remains a low income country. With a per capita income of US$950 in 2007, India ranks 122nd. 2 As well as a low average income, there are substantial disparities in economic performance between states. The average per capita Gross State Domestic...

From experience I was using previously Quickbooks online which was a free service and also had a mobile application as well but wasn’t always functional when needed. Since I currently am the only employee in the business, I manage what would be considered every department within an organization such as the sales, marketing, accounting, etc. Quickbooks online pretty much did what I needed which is have a list of customers and send them an invoice after work was performed. Unfortunately, they only allowed a maximum of five customers in which was fine in starting a business from the ground up, but...
