Uploads - Downloads - Streaming Explained

My husband likes to tell the story of a trip that he took with his grandfather driving from Placerville, California to Tacoma Park, Maryland on Highway 50 in 1962. Mostly it was a two lane highway. When they stopped to eat, it was either at a family owned greasy spoon or food provided in the local boarding house where they stayed. For the most part these two lane highways are a thing of the past (as are family owned greasy spoons and boarding houses) replaced by super highways (lined with McDonalds and Motel 6).

This kind of describes bandwidth way back when (minus McDonalds) - but now it is like a highway expanded from two-lane to six-lane allowing more information (traffic) to pass through - coming into your unit from an outside source is called download while moving from your unit to an outside source is upload. Rather than lanes, the bandwidth (highway - traffic capacity to/from your computing source in your location) is measured in Mbps - Mega bits per second. “Each Mbps represents the capacity to transfer 1 million bits each second, or roughly one small photo per second.”

Upload Speed is treated as if it doesn’t matter - just because it isn’t discussed much; If you are looking at internet plans, they list their download speed (information from the outside source to you) but generally not the upload speed. As a rule of thumb upload speed is 1/10 of whatever download speed is listed. Another important idea to keep handy is that an upload takes more time than a download BUT uses less bandwidth (or highway space). This slow down can impact uploading pictures and videos to social media. Consider video conferencing, VOIP calling - the upload speed will affect how you are seen or heard. ,“Slow or unstable upload speeds are often the cause of awkward frozen screens and broken audio when using apps like Skype or Zoom.”

Downloads are treated like downloads are ALL that matters. This is the speed that the internet connection receives the data from the internet source - how many Mega bits of data per second your activities require from the server. Average download speeds are 12 - 25 Mbps.

Around 10 Mbps / person (or devices) would be sufficient download speed for basic internet use (such as emailing and surfing). If there is remote working, use of video and music, your needs would be about 25 Mbps/person (device). But remember that devices to count in this estimation include Alexa in the kitchen, internet powered security devices, voice over internet phones (VOIP), tablets, computers.

Live Streaming is streaming media simultaneously recorded and broadcast in real-time over the internet. It is often referred to simply as streaming. Non-live media such as video-on-demand, vlogs, and YouTube videos are technically streamed, but not live-streamed. Streaming can be downloading or uploading - watching videos or listening to music is downloading. Live Streaming such as Zoom / Facetime is uploading. Watching a stream is downloading - being in the stream is uploading. If Livestream is important, slow upload speeds can make it spotty.

The shift has been to watch streaming TV and movies making bandwidth a much bigger issue. It depends on the size of your TV - the demand of data. Let’s say that you want to get a great picture on your 4K smart TV. You will need to stream 4k content and will need a connection of greater than 25 Mbps. A 1080p HD video will require 10 Mbps for clear, concise and consistent performance.

But this is just one device; this is assuming you are only streaming on one device at a time. Imagine one person is watching on the big screen in the living room while someone watches a video on a laptop in the bedroom.

Ok, we have covered a lot of ground, so here is some advice from Business Insider to close this out: “ Finally, put less stress on your internet connection. Using less apps at once, watching videos at a lower quality, and turning off devices when you're not using them are all great ways to reduce internet usage. And freeing up that bandwidth will let your most important data travel even quicker. ” Words to live by.

Speaking of traffic, have you noticed we have had a whole lot more here lately? More folks escaping to our great area combined with the summer construction, I guess. Maybe they are expanding the highway to accommodate greater traffic volume (broadband). You all drive safe - on the internet superhighway, the I-90 that links us all up here, or wherever your travels take you this summer.
