3G
Third generation technology (3G) is a network that offers users a wide range of more advanced services. Some services include voice telephony, video calls, and broadband wireless data. These services are all given in a mobile environment. According to AT&T a typical download speed for 3G technology would be at a peak of 1.7 mbps and an upload peak of 1.2 mbps. 3G uses a method that is used for data transmission and increases the capabilities of delivery speed; this is called high speed packet access (HSPA). The data transmission capabilities for this feature are a download speed of 14.4 Mbps and an upload speed of 5.8 Mbps. This technology has been pursed by a group called the Third Generation Partnership Project (3GPP). Currently 3G technology is not available in all locations around the world. Some cellular companies provide maps of where coverage is provided such as AT&T has done on there website with this link http://www.wireless.att.com/coverageviewer/popUp_3g.jsp.
I have been an iPhone owner since January 2008, before 3G technology was implemented. When the iPhone 3G came out I was in line to buy it. I was living at home near Chicago where AT&T covers 3G technology. When I first used the phone I took my old iPhone and my 3G iPhone and tested them to see which was faster. I was impressed with how quickly the 3G was at downloading a website. The main complaint that I have with 3G is that coverage is not offered everywhere. It is a done by demand. Since Muncie is not a metropolis that Indianapolis is there is no 3G coverage offered. Currently I am not using 3G due to the lack of availability. When I am visiting a city that does offer 3G, I enjoy the speed of checking/sending e-mails, browsing the internet and the map application on my iPhone. I think 3G is a great advancement in mobile technology and can’t wait to see what 4G will bring
