3G Speed Vs. DSL
You are thinking about getting rid of your DSL (digital subscriber line). You've seen commercials for 3G but aren't sure what it is. Your friends and colleagues use mobile devices that support this technology. They're sending and receiving email, watching television or downloading music. Some of your colleagues are working spreadsheets or typing memos. You would like to know more about these capabilities. 3G is an exciting technology, while DSL is reliable and mature, in many ways. There are advantages and disadvantages of these technologies.

Facts
-
3G transmits data at approximately 14.4 megabits per second for downlink and 5.8 megabits per second for uplink. Unlike its predecessors, 3G has more capabilities. It supports voice, video and data at wireless high-speed rates. Usually, DSL consists of speeds from 256 kilobits per second to 24,000 kilobits per second. This technology splits a phone line's frequency into two bands. As a result, voice uses the lower frequency, which is 4 KHz and below. Data uses the higher frequency, which is 25 KHz and above.
History
-
3G's predecessor, 2G, was designed to support voice and slow data delivery. Cellular providers used GPRS (general packet radio service), a packet-oriented mobile data service, with 2G. GPRS transmits data from 56 to 114 kilobits per second. A common version of DSL is ADSL, which has a faster download speed than upload. ADSL is used to transmit speed at approximately 8 megabits per second to customers over 2 kilometers of unshielded twisted-pair copper wire.

Potential
-
The International Telecommunication Union has come out with 4G. This technology will transmit data at approximately 1 gigabits per second, if you are stationary. If you are mobile, 4G will transmit data at about 100 megabits per second. ADSL+ can deliver data up to 24 megabits per second. This will depend on how far you are located from the DSLAM. DSLAM is a network device that is typically located at the phone company's central office. This device gets signals from numerous users' DSL connections. Using multiplexing methods, it then places these signals on a high-speed backbone network.
Considerations
-
Although many consumers and businesses use 3G technology around the world, it still has some issues, such as limited or no coverage in certain areas and expensive 3G phones. Many telecommunications' companies carry significant debt. When it comes to DSL, the further you are away from the DSLAM, the more likely you will experience attentuation. Attentuation occurs when there is a large amount of electrical resistance due to data moving between your modem and the DSLAM. As a result, you might lose data.
Types
-
The International Telecommunication Union developed 3G into different types of standards. Some of these include WiMAX, CDMA2000, GSM EDGE, UMTS, and DECT. DSL has several versions, such as ADSL, VDSL, GDSL, HDSL, IDSL, and RADSL.
