You can read a lot about broadband Internet connections with very high throughput. You can hear about 50 Mbps, 250 Mbps and even 500 Mbps Internet connections offered by several providers. Recently I saw an offer for 1 Gbps Internet line. Of course, in these cases only wired technologies counts, because of WiFi limitations. But it is not a topic for today.

I found a lot of posts like: “Download is fine, but when I want to sent some file then it is a disaster. What is going on?”. The good news are that it is not fault of their operating system or router. In these cases I always ask about the contract with provider. Most people then realize what they signed. They felt firsthand what asymmetric Internet connection means. To be more precisely, what are the differences?

Symmetric connection

Everyone would like to have this kind of Internet connection. Why? Because in case of this type of Internet connection, download and upload speeds are the same. Unfortunately, the reality is not so pretty. Most of ISP does not offer this kind of solutions for home users. Symmetric Internet lines are offered mostly for companies, because they send a lot of data (e.g. hosting companies). Several providers offer this also for home users, but these offers are more expensive. In my opinion it is not profitable, because statistic shows that home users download more data than they upload.

Asymmetric connection

Most of offers available on the market concern asymmetric Internet connections. In very simply words, you will able to download the file faster that to upload it. So, the next time if someone offers you 250 Mbps Internet line, then you will ask about the upload. Despite appearances, it is very important parameter of your Internet link. I bet that you want to send to your auntie movie from your school show quickly, isn’t you?

How to deal with it?

First, read before you sign! If you do not understand something, then ask about it. Carefully check information about download and upload speeds and what is guaranteed by provider. For example, my ISP offers asymmetric Internet connection with 1/10 ratio (i.e. upload is 10 times slower than download). Therefore I chose 150 Mbps, because I wanted to have 15 Mbps upload. I rarely can achieve 150 Mbps throughput for download, but I do not have any problems with getting my maximum throughput for upload.
