## What is the distance limit for ADSL service?

ADSL service is limited to a maximum distance of 18,000 feet (5460 m) between the DSL CPE and the DSLAM, although many ADSL providers place an even lower limit on the distance to ensure quality. The 18,000-foot distance limitation for ADSL is not a limitation for voice telephone calls, but for data transmission.

**What is the formula to calculate Internet speed?**

To see MBps, take the Mbps, and divide by eight or multiply by 0.125. People can find out roughly how long a large file will take to download if they take its size in megabytes, multiply by eight and then divide by their internet speed in Mbps. Mbps is usually used to show the maximum possible speed of a network.

### What is the speed of ADSL?

adsl has a maximum theoretical speed of up to 20 Mbps for download, and up to 1 Mbps for upload, however, most customers will achieve far less actual speeds. Our adsl plans provide the best possible speeds that are available on a standard telephone line at your premises.

**Is 20 Mbps fast enough?**

2-4 mbps: Enough for casual Web surfing, including checking email. 6-10 mbps: Usually an excellent Web surfing experience. Generally quick enough to stream a 1080p (high-def) video. 10-20 mbps: More appropriate for a “super user” who wants a reliable experience to stream content and/or make fast downloads.

## How slow is ADSL?

ADSL: Average speed** 8.8Mbps for downloading and 0.7Mbps for uploading.

**How far can you go with ADSL2?**

For distances between 3 km and 3.5 km, where ADSL speeds have fallen well below 10Mbps, ADSL2+ and ADSL2 still provide worthwhile increases in connection speeds. There is very little difference in performance at distances above 4 km.

### How fast can I download with ADSL2?

With ADSL2 your modem can connect at speeds of up to 24Mbps. However this DOES NOT mean that you can, or are even likely to, download at anywhere near that speed.

**What is the speed distance time Formula?**

Speed Distance Time Formula. Speed is the rate at which an object moves. It’s a very basic concept in motion and all about how fast or slow an object can move. Speed is simply distance divided by the time where distance is directly proportional to velocity when time is constant.

## How do I use the SG DSL Speed Calculator?

forgot password? The SG DSL Speed Calculator is a tool for quick estimation of the maximum attainable ADSL/ADSL2+/VDSL sync speed based on signal attenuation. To use the calculator simply fill in the downstream attenuation number (dB) from your DSL modem, and all other values will be calculated automatically.
