Top best answers to the question «Why is cable internet asymmetric»

Copper and coax have a data relationship problem—data doesn't move at the same speeds in both directions. This inherent asymmetry is why service providers pitch their download speeds, and not their upload speeds. In extreme cases, such as AT&T Uverse, the difference between download and upload speeds can be 20X.

FAQ

Those who are looking for an answer to the question «Why is cable internet asymmetric?» often ask the following questions:

đź’» Why is cable internet asymmetric connection?

Symmetrical connections are exactly what they sound like; a connection with equal download and upload speeds. For example, with a 500/500 Mbps fibre internet connection you get 500 Mbps of download AND 500 Mbps of upload speeds. An asymmetrical connection, however, does NOT have equal download/upload speeds.

đź’» Why is cable internet asymmetric marketing?

While Verizon probably has no problem with offering Symmetrical speeds and not considering the fact that more likely the download will be used, you will also find that the PON system Verizon uses on FiOs is also not symmetrical in nature.

Symmetrical connections are exactly what they sound like; a connection with equal download and upload speeds. For example, with a 500/500 Mbps fibre internet connection you get 500 Mbps of download AND 500 Mbps of upload speeds. An asymmetrical connection, however, does NOT have equal download/upload speeds.

During peak times, speeds are likely to be much slower because the connection bandwidth is shared across other businesses. With an asymmetrical internet connection, the business may experience very slow upload speeds even if no one else in the office is uploading at that time.

The asymmetric provisioning of internet circuits reflects demand. 90% of users download far more than they upload. So infrastructure is designed that way (and is cheaper).

If you test your Internet speed at home, you will more than likely notice that your upload speeds are only a fraction of the download speeds. This is what is known as an asymmetrical connection. An asymmetrical connection usually works best in an office environment where you can be flexible with bandwidth.
