mobile phone impact on the culture of the comunity

mobile comunication have played and influencial part in media transforming over the past two decades, and it is aslo have been a great role in our lifes. the mobile phone is now used by 1.3 billion people worldwide, and more than 14 million subcribers in Asia. In 2003 there were an estimation of 1,340667 mobile phone subscriber worlwide in 2003; up frm approximately 91 million in 1995. more people now use mobile phone than they used fix phone, this shows that the mobile phone has givin the culture in our comunity a great impact. In many countries, more households have mobile phone conections than they do tradisional fixed phones. since the mobile phone was marketed commercially, the mobile phones has become much more than a device for voice telephones calls, it has become a central culture technology in its own right. mobile are associated with significant culture transformation, such as as the role of mobile in forming and maintaining social network. so the mobile phone have given such impact untill the subcribers has forgeten about the fix lin phones and they are now more dependent on mobile phones. there are now quite a number of studies of how mobile phones have been taken up in manny diferent countries, what distinctive culture and communicative practices have developed in different settings, and what mobile phones signify in different places. where there is not sufficient space here to place mobile phones in the broder landscape of digital media convergence, there are now important developments unfolding in at least 4 areas. the 4 eras are the intensification of mobile as a technology and media device, the rise of the mobile learning, mobile commrce, mobile for information and entertaiment, mobiles as game platform, the proferation of mobile communication technologies with growth of portable digital assistant, new new cultures of used around devices such as the nokia mobile phones, the interpenetration of mobile with new television formats and paltforms and more. this shows that a new culture wich is called the "mobile culture" has formed and daily life without mobile phones are missarable.

How it works

Most current mobile phones connect to a cellular network consisting of switching points and base stations owned by a mobile network operator. but first of all, A cellular network is a radio network made up of a number of radio cells (or just cells) each served by at least one fixed-location transceiver known as a cell site or base station. These cells cover different land areas to provide radio coverage over a wider area than the area of one cell, so that a variable number of portable transceivers can be used in any one cell and moved through more than one cell during transmission. Here is the example of the cellular network radio tower and the structure of the 2G cellular network:

Then the base staion is a GPS receiver at an accurately-known fixed location which is used to derive correction information for nearby portable GPS receivers. This correction data allows propagation and other effects to be corrected out of the position data obtained by the mobile stations, which gives greatly increased location precision and accuracy over the results obtained by uncorrected GPS receivers.Then, a mobile network operator (MNO), also known as mobile phone operator ,carrier service provider (CSP), wireless service provider, wireless carrier, mobile phone operator, or cellular company, is a telephone company that provides services for mobile phone subscribers.The process of becoming a mobile network operator within a country usually begins by acquiring a radio spectrum license from the government. The precise spectrum obtained does depend on the type of mobile phone technology the operator intends to deploy. For example, a Global System for Mobile Communications (GSM) network will require a GSM frequency range.The government may allocate spectrum using whichever method it chooses. example of mobile network operator in Malaysia are DIGI, MAXIS, CELLCOM, U-MOBILE, and ect

Technological development of handphones

the handphone technologhy have moved away from a hard-wired networked world to an increasingly wireless networked. With the emergence of Smart Handphones, people on the go prefer to use hand held devices to work on a 24 x 7 basis cutting across geographical and time barriers. The remarkable technological breakthroughs that have taken place in the wireless networking domain have led to the emergence of thriving mobile communities that deliver content-rich applications for the high-end mobile devices that are now readily available.
nowadays the haphones companies have genrated a team of specialist to drive the Mobile Application Development Practice. some organisation of handphones also offer custom mobile application development for a host of smart phones and its various OS(s) including Blackberry, iPhone, Symbian, Windows Mobile, Android and J2ME mobile platforms.

now wit the development of the camera phones. The camera phone, like many complex systems, is the result of converging and enabling technologies. There are dozens of relevant patents dating back as far as the 1960s Compared to digital camera of the 90s, a consumer-viable camera in a mobile phone would require far less power and a higher level of camera electronics integration to permit the miniaturization. The CMOS active pixel image sensor "camera-on-a-chip" developed by Dr. Eric Fossum and his teamin the early 1990s achieved the first step of realizing the modern camera phone as described in a March 1995 Business Week article.[While the first camera phones, as successfully marketed by J-Phone in Japan, used CCD sensors and not CMOS sensors, more than 90% of camera phones sold today use CMOS image sensor technology.

history of handphones

April 3, 2003 marked the 30th anniversary of the first public telephone call placed on a portable cellular phone. Martin Cooper ( now chairman, CEO, and co-founder of ArrayComm Inc) placed that call on April 3, 1973, while general manager of Motorola's Communications Systems Division. It was the incarnation of his vision for personal wireless communications, distinct from cellular car phones. That first call, placed to Cooper's rival at AT&T's Bell Labs from the streets of New York City, caused a fundamental technology and communications market shift toward the person and away from the place.

"People want to talk to other people - not a house, or an office, or a car. Given a choice, people will demand the freedom to communicate wherever they are, unfettered by the infamous copper wire. It is that freedom we sought to vividly demonstrate in 1973," said Martin Cooper.
Martin Cooperadded, "As I walked down the street while talking on the phone, sophisticated New Yorkers gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973, there weren't cordless telephones, let alone cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter - probably one of the more dangerous things I have ever done in my life."
Following the April 3, 1973, public demonstration, using a "brick"-like 30-ounce phone, Cooper started the 10-year process of bringing the portable cell phone to market. Motorola introduced the 16-ounce "DynaTAC" phone into commercial service in 1983, with each phone costing the consumer $3,500. It took seven additional years before there were a million subscribers in the United States. Today, there are more cellular subscribers than wireline phone subscribers in the world, with mobile phones weighing as little as 3 ounces.
