INTRODUCTION

A mobile phone (also known as a wireless phone or cellular phone) is a short-range, electronic device used for mobile voice or data communication over a network of specialized base stations known as cell sites. 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. 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…...

...personal mobile phone use in staff and team meetings. A staff survey on attitudes towards the use of mobile phones in the staff / team meetings was conducted. The results indicate that the majority of staff find mobile phone use a major issue in staff meetings. The report concludes that personal mobile phones are disruptive and should be turned off in meetings. It is recommended that UniLab develops a company policy banning the use of mobile phones except in exceptional circumstances. Introduction There has been a massive increase in the use of personal mobile phones over the past five years and there is every indication that this will continue. According to Black (2002) by 2008 almost 100% of working people in Australia will carry personal mobile phones. Black describes this phenomenon as ‘serious in the extreme, potentially undermining the foundations of communication in our society’ (2002, p 167). Currently at UniLab 89% of staff have personal mobile phones. Recently a number of staff have complained about the use of personal mobile phones in meetings and asked what the official company policy is. At present there is no official company policy regarding phone use. This report examines the issue of mobile phone usage in staff meetings and small team meetings. It does not seek to examine the use of mobile phones in the workplace at other times, although some concerns were raised. For the purposes of this report a personal mobile......

Uses and Abuses of Mobile Phone

...cell phones are a wonderful convenience of modern life; for others, they are irritating contraptions that should be banned from public areas. A mobile phone or cell phone is an electronic telecommunication device with the same basic capability as a conventional fixed-line telephone, but which is also entirely portable and is not required to be connected with a wire to the telephone network. Most current mobile phones connect instead to the network using a wireless radio wave transmission technology. The mobile phone communicates via a cellular network of base stations, also known as cell sites, which are in turn linked to the conventional telephone networks. In addition to the standard voice function of a telephone, a mobile phone can support many additional services such as SMS for text messaging, packet switching for access to the Internet, and MMS for sending and receiving photos and videos. In less than twenty years, mobile phones have gone from being rare and expensive pieces of equipment used by businesses to an all pervasive low-cost personal item. In many countries, mobile phones now outnumber land-line telephones, with most adults and many children now owning mobile phones. It is not uncommon for young adults to simply own a mobile phone instead of a land-line for their residence. In some developing countries, where there is little existing fixed-line infrastructure, the mobile phone has become widespread. With high levels of mobile telephone penetration, a mobile......

...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......

...campaigns and sales force alignment to suit their niche segments. Communication and Distribution Channels The identified product positioning requires appropriate communication channels which can reach geographically dispersed and socio-economically diverse target customer segments. The distribution channels contribute by delivering on the promise made through the communications during the customer acquisition and servicing cycle. Insurers will need to deploy innovative distribution channels to significantly improve the ability to reach target customers and communicate the value proposition at optimal cost. Insurers are increasingly using communication and distribution channels like social media, self-help web-portals, bundling services with mobile service providers and alliance with malls. Work-site marketing, groups like co-operative housing societies and unrelated products‟ distribution channels are increasingly being leveraged by insurers to improve distribution reach. For example, an experiment by a leading insurer in South Africa of distributing insurance products through a retail clothing store has been successful. Insurers have also leveraged Self-Help Groups (SHGs) and Business Correspondent outlets of banks in rural areas to distribute micro-insurance products. Aligning the Value Proposition with Customer segments To ensure effectiveness of innovatively re-defined customer value proposition, insurers will need to address specific segments of customers.......

...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......

Summary There are many factors that would affect these results, including the number of calls made per month, the length of the call, the cost of calls and SMSs, the number of free calls made to the same mobile provider, the number of SMS messages sent, and the use of mobile data for email, social networking and Internet browsing – the cost would depend on how much data is allowed in the plan The extras provided in the plan are also a very important factor when selecting the right plan for a mobile user. If the plan provides free calls to the same provider, and the friends and family are also with that provider, this would reduce costs. The amount of data provided with the plan would be very important to someone who needs access to the Internet 2. B. Spreadsheet Table 2. C.

...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......

Mobile Phone

...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......
