The Digital Subscriber Line (DSL) uses existing phone lines to provide high-speed Internet access. DSL provides this access without dialing up phone lines just like dial-up Internet connections.
Compared to cable internet service performance, DSL speeds have historically been a little behind. However, as technology improves, DSL Internet connection speeds are increasing and service providers upgrade their network infrastructure.
The speed of DSL you can use varies depending on the provider you choose and the package you offer. Your equipment can also affect speed. If you use a wireless router and your computer is away from the router, you can expect a slower speed. This happens if your router or PC is old enough.
How fast is DSL?
The average DSL internet speed is almost as fast as a cable internet connection. However, cable connections are often shared with other customers around you, which can slow down. The DSL service is not shared with others, so your neighbors’ activity does not affect your speed.
DSL speeds vary widely by package options. If you want to watch too much streaming content, you want your provider to have a fast package. If you are not online 24/7, a more affordable, but slower package might be right for you. Most providers choose DSL services with a different bandwidth.
For example, AT&T offers a range of services that can deliver speeds of up to 6 Mbps and another range that can deliver up to 100 Mbps (VDSL or very high-bit-rate DSL). Slow, inexpensive planning works well for social media, browsing and email. Gamers and TV binge-fast planning fit well. For comparable cable speeds, their Fiber Plan delivers up to 1000 Mbps.
DSL download and upload speeds
Depending on the network you use, your DSL speed may vary.
DSL providers often advertise their service speeds using a combination of two bandwidth numbers: one download speed and one upload speed. When you select a internet service provider, check both download and upload speeds.
Residential DSL services generally provide faster speeds for downloads than uploads because most users devote more time to download activities. This arrangement is called asymmetric DSL (ADSL) service. In ADSL, the download speed is much higher than the upload speed. With Symmetric DSL (SDSL), the two numbers are the same.
DSL speed difference between homes
The rated maximum bandwidth of a DSL connection is often unreachable and the actual speed varies between households. Factors affecting DSL speed include:
Resident Phone Line Quality in Your Residence: Environments with improved copper wiring can achieve some faster DSL speeds. Fiber-optic lines are much faster.
Distance between hub and home: The length of the phone line between the resident and the phone company hub affects the speed. DSL technology is distance-sensitive because its performance decreases when the hub passes.
Mal Service Errors: DSL speeds may fall suddenly if the service provider is experiencing technical difficulties in its network and is usually stable. The speed usually returns to normal after a few minutes.
Before re-opening their residences, customers can do very little about changing certain items. However, other factors can be changed to improve connection speed.
