It is an undeniable fact that we have seen great changes in the way we communicate since the last decade. More and more sophisticated means of communication is available nowadays and seeing the trends it don’t seem it is going to stop here. Along with the new mobile communication media, we have also witnessed a lot of jargons, which we will try to describe in this article. The more common these days is the Blue Tooth. Well it is not some strange form of tooth decay as you might at first think. “It is a new technology that promises to change considerably the way we use machines. The Blue Tooth is designed to replace cables.

Whenever we make use of phone the cable normally carries the information that we want to deliver in other words the speech, and transmitting it at a special occurrence to a receiver Blue Tooth chip in other words the processor, which will then give the information received to the phone or other media. Blue Tooth is wireless. When you are travelling, walking or even driving for some there is no need to worry about cable to connect to your mobile to use the earphone. ” (http://www. palowireless. com/infotooth/whatis. asp Accessed date 01/10/03) “Also when you use it you don’t require doing anything special to make it work.

The phones find one another and start a conversation without any user input at all. Blue Tooth communicates on a high frequency, which has been set aside by international agreement for the use of industrial, scientific and medical devices (ISM). A number of equipments that you may already use take advantage of this same radio-frequency band. Baby monitors, garage-door openers and the newest generation of cordless phones all make use of frequencies in the ISM band. It has been a very crucial part of the design process of Blue Tooth that these other devices don’t interfere with one another.

” (http://electronics. howstuffworks. com/bluetooth2. htm Accessed date 01/10/03) The next that we hear very often again is the GPRS. Well the GPRS stands for the General Packet Radio Services. “It is a wireless communication that can send a lot of information without affecting the connection to the Internet for mobile phone. With the GPRS system it is very easy to send Short Message Service(SMS) or mobile texts as we currently know the term. GPRS is also a complement of Blue Tooth, a standard for replacing wired connections between devices with wireless radio connections. ”

(http://searchnetworking. techtarget. com/sDefinition/0,,sid7_gci213689,00. html Accesseddate01/10/03) The other one that we hear a lot is the 3G. 3G stand for third-generation. ” It refers to near-future developments in personal and business wireless technology, especially mobile communications. This phase is expected to reach maturity between the years 2003 and 2005. 3G can use the Internet at a high speed, send more bigger, voice of a higher quality, video transmission at a high rate which means it is very quick. It offers a consistent set of services to mobile computer and phone users no matter where they are located in the world.

With 3G mobiles you can take your phone and go throughout Europe, Japan and North America and you will get connection. 3G is generally considered appropriate mainly to mobile wireless, it is also relevant to fixed wireless and portable wireless. The last 3G systems might be operational from any location on, or over, the earth’s surface, including use in homes, businesses or everywhere. Proponents of 3G technologies promise that it will keep people connected at all times and in all places. ” ( http://www. 3g-generation. com/what_is. htm Accessed date 01/10/03)

The next one that we keep constantly saying is the CDMA. “Short for Code-Division Multiple Access, a digital cellular technology that uses spread-spectrum techniques. CDMA changes the conversation and tags it with a special frequency code and of better quality. The information or the speech is then spread across the frequency group in a random pattern. The receiving device is instructed to decode only the information corresponding to a particular code to reconstruct the signal or the speech. CDMA is used mainly with personal communications devices such as mobile phones.

CDMA networks use a system called soft handoff, which minimizes signal or speech that we talk to break-up as a handset passes from one cell to another. CDMA is compatible with other cellular technologies; this allows for nationwide travelling. ” (http://searchmobilecomputing. techtarget. com/sDefinition/0,,sid40_gci214486,00. html Accessed date 01/10/03) “CDMA is a military technology first used during World War II by the English allies to foil German attempts at jamming transmissions.

The allies decided to transmit over several frequencies, instead of one, making it difficult for the Germans to pick up the complete signal”(http://www. webopedia. com/TERM/C/CDMA. html Accessed date 01/10/03) And the other one that is also common these days is the WLL. “The WLL is sometimes called radio in the loop (RITL) or fixed-radio access (FRA), WLL is a system that connects subscribers to the telephone network using radio signals as a substitute for copper for all or part of the connection between the subscriber and the control. In developed economies, WLL helps developed economies to open competition in the local loop, enabling new operators to bypass existing wire line networks to deliver information as more commonly as we know it, the speech. “( http://www. iec. org/online/tutorials/wll/ Accessed date 01/10/03) J.
