What is 3G?

3G is the third generation of wireless data communication protocols. It supersedes GPRS, EDGE (Enhanced Data rates for Global Evolution) or 2.5G, the slower yet incredibly popular GSM (Global System for Mobile Communications), and CDMA (Code-Division Multiple Access) or 2G. Typically, 3G speeds are measured in megabits per second, rather than kilobits per second, so 3G is essentially broadband in your pocket. 3G and its successors, such as 4G, allow extremely large amounts of data to be transmitted to and from a phone at the high speeds typically found on desktop connections.

Data speeds have been a limiting factor in the development of mobile applications in the past, and although we must always design for the lowest common denominator, the future looks good. You can already see widespread use of video communication and even mobile TV streaming. In addition to the great compression ratios that result in much smaller downloads that Flash gives you, it can make full use of these higher data speeds to offer real-time information, multiplayer games, chats, virtual tours, and even group video conferencing.

Cultural acceptance

The use of mobile devices for everything in addition to voice calls has exploded in popularity all over the world. It’s not just a case of necessity. You can see these trends beginning in Asia (particularly in Japan); spreading west across Europe, past Nokia’s headquarters in Finland and engulfing the United Kingdom; before racing across the Atlantic and Pacific to hit the United States from both east and west.

Mobile devices presently provide a wide variety of features other than interpersonal communication, including music, news, weather, GPS navigation, road maps (trip planners), video, and photography to name a few. What we are beginning to see is the cultural acceptance of mobile devices as necessary utilities as well as portable entertainment centers. Service providers like travel agencies, real estate agents, e-learning schools, and dating services will soon take advantage of mobile technology to provide
more people with the information they provide, wherever those people are.

Decreasing cost

One thing that has held the mobile content industry back is the cost of the content itself. In early 2005, a ring tone could cost anything from $1 to $5. Costs were also hidden in the data charges incurred by simply searching for content to buy online. In response to customer dissatisfaction, most service operators allow you to browse their own pages free of charge and pay only for the content you download, and the prices are dropping rapidly.

You may currently pay around $2 to download a megabyte of data over a 2.5G network, which equates to about 1,000 plain-text e-mails. However, the high-speed nature of 3G brings with it streaming video and full-track music, which dictate that this price must fall, as a single megabyte may only represent a few minutes of video. Value for money is, after all, still an important factor for consumers. As the price of downloading falls, the number of people downloading rich content rises, and the stigma attached to these premium content services will fade.
