Every minute of every day some new form of technology is being invented. Technology is popping up all over the place and it does not seem to be slowing down anytime soon. Every year companies try to out do each other by coming up with the biggest and best product and knock their competitors out of the water. Now, if you buy a computer, IPod or any other electronic device, it is practically out of date before you even walk out the door of the store because a new company came up with a better idea. This is why the career field of computers and technology continues to grow making room for individuals with a technology degree.

When the IPod was first marketed, people all over the world rushed out to the nearest electronic store to purchase the latest technological craze. As soon as they took that product home and got used to the features, Apple was pushing out a new product, the IPod Nano. This IPod was smaller than the first and had more memory, making it more portable and easier to use. Similar to Apple, video game companies are coming out with new game systems and games before customers are used to the one they already have. With the high turn around of computer games and electronic devices, the need for experts with a technology degree continues to grow. That makes the technology career field one of the fastest growing career fields today.

With a technology degree, individuals can work in many different places and hold various jobs. These jobs include computer programming, network engineering, information technology, database technologies, network security and management information systems. All of these fields offer numerous jobs and opportunities for students. Because of the diverse curriculum and the wealth of knowledge available in these technology programs, students are not stuck in one dead end job for their whole life. Receiving a degree in a technology field allows students flexibility and the ability to adapt to any computer or electronic related career.

There are numerous institutions in the United States that offer a technology degree, but not all of them offer certification in certain programs as well. Not only do employers look for employee candidates who have a degree, they also look for candidates who are knowledgeable, have real world experience and are certified in certain programs. Gaining a certification will set students apart from other candidates who do not have these certifications or real world experience. By obtaining a technology degree, students can become a Cisco Certified Network Associate, a Microsoft Certified Systems Engineer, a Microsoft Certified Systems Administrator or a Microsoft Certified Application Developer among other certifications.

While obtaining a technology degree, there are also many opportunities for students to gain hands-on experience in the field of computers and electronics. Since there is a large job market in this particular career field, there leaves open the opportunity for a large internship market. Internships are important to students because employers look for individuals with real world experience. This career field is so fast paced that one minute an individual can be programming a computer game and the next minute they can be coming up with a new database. This makes it important to gain as much real world experience as possible before attempting to break into the work force. It is also important for individuals to stay on top of the current technology that is out there. New products come out every day leaving room for new improvements and advancements in technology.

From the heavy cordless phones of the 1980′s to the smart phones of today, cellular phone technology has undergone a incredible change. But have you ever wondered how you can call to your well wisher in the whole world with the usage of a mobile phone? You also have knowledge about the main features such as WAP and GPRS from the cell phone vendors and service providers. But you must aware of what they really mean?

There are numerous mobile technologies. So next time, when you are going to purchase a phone, you should know what technologies it has.

Generations of mobile communications

In the late 1970s, the first generation (1G) of mobile communications was introduced; it was primarily used for voice transfer. Second generation (2G) systems came into existence in the early 1990s and was further developed to 2.5G, which includes high technologies such as TDMA, GSM and CDMA. These technologies were used for voice and data.

The next generation of mobile communications is 3G which delivers data speeds from 384 kbps to 2 Mbps and over wireless interfaces such as GSM, TDMA and CDMA.

Mobile phone access technologies

Frequency division multiple access (FDMA)
The first-generation analog mobile access method; for each call, FDMA uses separate frequencies. For instance, if there are four stations, each will receive their own frequency. So there is no interference between them. It reduces interference, but limits the number of users.

Time division multiple access (TDMA)
TDMA allocates unique time slots to each user within each channel, thus allowing many users to access the radio frequency without anyone’s interference. Each mobile conversation uses only a particular frequency slot of the time.

Code division multiple access (CDMA)
Commercially introduced in 1995 by Qualcomm, CDMA quickly became one of the world’s fastest-growing wireless technologies. 3G CDMA networks provide more capacity for voice traffic with high-speed data capabilities, hence many cellular service providers are now building or upgrading to it.

CDMA is used in both 2G and 3G wireless technologies. Indian Cell operators such as Reliance IndiaMobile, TATA Indicom, BSNL and MTNL’s Garuda all use CDMA2000 technology and its variant CDMA1x.

Global system for mobile communications (GSM)
GSM is now the worldwide standard technology for mobile communications. It is developed on TDMA protocol in Europe. GSM provides a high level of security, globally accepted technology standards and superior sound quality.

For any GSM phone to work, it needs a Subscriber Identity Module (SIM), a card which contains your telephone account information. So, an Indian GSM phone can be used in any part of the world.

Wireless technology platforms

1) GPRS
GPRS (General Packet Radio Services) is an enhancement to GSM technology that integrates GSM and IP technology. GPRS offers to access the Internet at the very high speed. So you can check your email on the move and surf the Web at very high speed. Currently BPL Mobile and Hutch (Orange in Mumbai) offer GPRS services in India.

2) WAP
In this high technology age, people on the move need any-time access to the Net. This is where WAP comes in. It facilitates us to Internet access from cell phones. It is an open standard for wireless protocols that is independent of the service providers. The cell phone must have a WAP browser to display Web content. Now-a-days, cell phones often come equipped with WAP browser and GPRS technology.
WAP and GPRS also enable the user to download games, send mail and even transfer your messages to your PC.

3) EDGE
The new EDGE (Enhanced Data GSM Environment) interface has been developed specifically to meet the bandwidth needs of 3G. This technology is promoted by Ericsson, it also offers high-speed data transfers over GSM networks with just a software upgrade to the handset. EDGE technology allows speeds up to 384 kbps.
