And what width do we need for which applications? Let’s start with the definition: Bandwidth indicates the amount of the smallest unit of digital data, the bit, that can be transmitted per second via a line or radio frequency. And this is not yet completely correct. To be more precise, the bandwidth refers to the usable frequency area of a transmission medium. The two values are interdependent. Let’s move on.
The exact definition is quite interesting for engineers anyway. For customers, at home or in the business, one thing matters most: getting the highest possible value. Bandwidth depends on the actual usage of the Internet connection. The Jom Apply Unifi is the best choice there.
Here are some examples of applications and required bandwidth:
The bandwidth required for:
- E-mail: 1 MBit / s or more depending on the size of the annexes sent
- Streaming music: 6 MBit / s
- Surfing the Internet: 10 MBit / s Web pages with many images require more bandwidth
- VoIP: 16 MBit / s (or more if webcam images are also to be transmitted)
- Internet TV (e.g. Netflix): 6 MBit / s (Full-HD), 20 MBit / s (4K)
- Online games:> 100 MBit / s for multiplayer games
At first glance, the bandwidths of the basic tariffs of the Internet providers appear to be sufficient. They offer bandwidths of a few tens of MBit / s. If several people or applications have simultaneous access to the Internet, for example in a small business, bandwidth can quickly reach its limits. It’s fatal when a small businesswoman holds a video conference with an important client, her partner is simultaneously watching a movie on Netflix on the same wi-fi network and her son starts an online game on his laptop.
The disturbances during the video conference are then preprogrammed. Small businesses and the self-employed who receive telephone (business and private), Internet and TV on a single line, with a single contract, have a vested interest in not restricting bandwidth too much. Often, they work at the computer with software connected to the Internet without realizing it.
Warning: background apps reduce speed
Some programs, such as online accounting software or collaboration tools such as Asana, no longer work on the computer but in the cloud, just like backup services such as Google Drive or Onedrive. A lot of data traffic is perpetually playing in the background and this not only when you download data, or receive data from the Internet, but also when uploading data, so when you send data, for example, to the cloud.
