Most consumer connections are asymmetric downloads are faster than uploads as they work on the principle that most people will download far more than they upload. For most relationships, such as ADSL, they are probably in the region of to for download: upload speeds. This has the side effect that when your upload buffer fills, it will take longer to clear than anything in the buffer for downloads at the ISP side. This means your download link will download everything well before the uploads have finished causing your download link to pause as it waits for more data.
You effectively reach a point of symmetry: One packet up means you can get one packet back down again and gives you the result you see when trying to download while you upload at the same time. This can help in some situations, especially with smaller downloads, by allowing more data to be sent in one go. Now that you understand the basics of internet bandwidth speeds, what is the best internet speed for video conferencing? There are varying schools of thought around what is the best internet speed for video conferencing.
Several factors can affect the quality of your video beyond the download and upload speed. They include:. This can slow down your speed. Video conferencing typically requires around 1. Generally, the higher the Mbps the better, so some providers recommend a 3 Mbps connection to improve the experience. According to HighSpeedInternet. You can go to speedtest.
Are there other ways to overcome bandwidth issues during web conferencing? It takes less bandwidth to share your picture instead of live video, so consider just uploading a picture of yourself instead of sharing your face on the webcam.
You could also consider adjusting your webcam resolution away from HD, to save a little bandwidth. Another way to enhance your video conferencing experience is to select a video conferencing provider like MegaMeeting. MegaMeeting is a browser-based video conferencing solution. Net , the maximum speed that I got in most rooms was 20 Mbps. Since I can transfer data at full speed when I connected directly to my router, I know that my wireless network is the bottleneck.
Perhaps changing the wireless channel, moving my access point to a more central location, or installing a network extender will help improve my connection speed. Failing that, it might be time to look for a better router. If you decide you need to go wired, you can do the obvious thing and run ethernet cable between your router and your computer, which is fine if your computer is near your router. Alternatively you can look at some of the power-line networking solutions that are available - not as convenient as wireless, but better than running exposed cables through hallways and way cheaper than running cables through the wall..
Unfortunately, it may take a bit of trial and error to figure out what works best for you. Not surprisingly, your choice of connection technology, and your ISP's network will have a big impact on your connection speed. The shorter the distance between your house and the point where the phone company aggregates traffic, the faster your potential connection will be. The benefit is that these short connections support more advanced variants of DSL that offer higher potential connection speeds and can also be used to offer television service.
In my case the difference is pretty substantial. I get a 50 Mbps connection in my house, and 1 Mbps at my friend's cottage. Likewise, some locations in cities may still have relatively slow speeds due to their distance from the central office or remote terminal.
The architecture of cable networks is different. Think of it like a bunch of streets feeding into a major artery. In this sense, cable is a shared network. The more people sharing the connection and the more intensively they are using it at the same time, the slower the effective speeds will be for each user.
Cable companies have been doing lots of work to reduce the number of people that share the same connection. By splitting the nodes into smaller and smaller groups of households, they are better able to control the speeds that their customers get. If you have the option of buying a fiber connection and the price is reasonable, take it. Unfortunately, fiber Internet access isn't broadly available to consumers and small business customers due to the high cost of replacing existing networks with fiber.
Outside of the access technology that is used, there are several other areas within the ISP network that can cause slow upload and download speeds. A major factor here is how much capacity your network provider has provisioned per subscriber. As an easy to understand example, imagine an ISP with customers, each of which has a 25 Mbps Internet connection.
At some point, this service provider connects to the Internet there are some major simplifications here. All of the traffic for the customers is aggregated and sent in and out of the network. Instead, it over-subscribes this bandwidth. Different ISPs are going to have different assumptions around contention.
Perhaps that low cost DSL reseller with unlimited access is cutting costs by increasing the contention ratio or provisioning less capacity per customer. At in the morning, this may be fine, but at peak times the effective throughput may not be satisfactory as people fight for capacity. Network providers need to continually add capacity as usage patterns change.
As more people use bandwidth intensive services like Netflix during peak times, service providers must add capacity or use other alternatives like caching content locally or partnering with content delivery networks. ISPs can fall behind on adding capacity and this can lead to degraded performance.
As a real-world example, Comcast customers have complained about poor performance. Netflix and Comcast pointed fingers back and forth about whose fault it was, but it was really a protracted negotiation about who should pay for the increased capacity required to support growing Netflix usage.
