Do you really enjoy lines over 150 Mbps?

On the bandwagon, the best idea prevails, however there is always the question of whether we will not engage more than we actually use on a daily basis. Point Pedro Serrahima asked the question on his Twitter account, where he challenged Netizens Name of home applications over 150 Mbps.

The 150 Mbps bandwidth assumes a theoretical maximum download speed of about 18MB / s, which is difficult but impossible for a normal user to fully exploit. Here we tell you Advantages of high bandwidth in downloads, streaming and games -No.

Is 150 Mbps enough?

According to O2 Spain director Point Pedro Serrahima, 150 Mbps should be enough for any home. This amount is half of what the company offers in its 300Mbps fiber mode, and a quarter of the current maximum 600 Mbps symmetry.

The discussion took place following a comment by Twitter user ek Deccaar on a free 5GB O2 bonus book. Download Fiber at 600 Mbps. The answer was immediate:

As soon as you show me a home application that requires more than 150 Mbps

– Point Pedro Serrahima (serrahim) November 18, 2019

Responses received include remote savings, improved online gaming performance and content downloads, but Serrahima struggled again. Rejects all possibilities.

-1GB Download = 33 seconds (Suppose you find a cloud that provides 30MB / s for you).

– Packed Fortnite: With only 100MB / h = 10Mbps you will get many at once. The important thing here is not the bandwidth, but the delay

– 4K Ultra HD Video = 25 Mbps

– Point Pedro Serrahima (serrahim) November 19, 2019

Note that approximately 150 Mbps (megabytes per second) 18.75 MB / V Theorem If one takes into account the factors related to the way data is carried through the network they are actually a little less. In the previous calculation with download GPS, Serahima performed his approximate calculation based on symmetrical 300 Mbps (theoretical 37.5 MB / s), so downloading 1 GB file can reach 30 MB / V in half a minute.

After all, it seems that in the end the reasons were able to convince Serrahima O2 was able to double its fiber speed to 600 Mbps In February 2020, three months after the conversation.

For downloads, bandwidth matters

The above calculation is correct, but there is no denying that the biggest advantage of high bandwidth Upload and download speed. The higher the bandwidth, the less time you have to wait to finish downloading or downloading a file.

File transfers are the best way to use the highest bandwidth

This applies to a variety of events that one needs Upload or download large files, And it is becoming more and more common without entering the complex arena of downloading content.

For example, Full HDD backups, videos and photos in original quality Or any file of several hundred megabytes that must be moved from one place to another on the Internet for some reason.

You will, yes, need it The server where you receive or send data This theory of 150 Mbps to benefit from higher bandwidth can give you more than 18 MB / s of data flow. It may be a little more complicated, but not impossible.

Now, the trick has been around since the beginning of ADSL: Connect with multiple servers to increase speed. In the past we did this with popular download managers, today there are sophisticated ways to do this just like PitTorrent. Yes, it has more applications than hacking, and in the past, Facebook and Twitter used it to share files and code between their branches.

Single bandwidth It is difficult to use all bandwidth, however Once the sources are added Exceeding 18MB / s of about 150Mbps symmetry is not particularly difficult. The difference is that it takes 57 seconds to download 1GB movie over 150 Mbps connection and 14 seconds for 600 Mbps connection. This, of course, maintained the maximum speed throughout the transaction.

In streaming, it all adds up

Serrahima mentions in his tweet that it takes 25 Mbps to play a video in Ultra HD 4K quality, the truth is 150 Mbps bandwidth is hard to run out For streaming, but impossible.

Just like downloading files How many users are using the same link What they do at the same time. For example, four people watching 4K streaming videos may already be using 100 Mbps, a PC that downloads Windows Update, or a cell phone that records its copy simultaneously. Save their videos to the cloud.

It is true that the previous example was slightly longer, and it would be difficult for four people to watch streaming videos at the best quality at the same time, and the router would maintain speed. Today, it is difficult to use high bandwidth in a home with streaming alone, It will not be so when technologies like Stadia get better in the future.

In games this is not really necessary

With regard to online games, bandwidth usage is reduced Download content in a timely manner When there are any updates or map that we did not download at that time.

Really in multiplayer games No large amount of data was sent (We see this here on Fortnight and PUBG), which happens often. The most important thing in online gaming is low latency.

Delay The time it takes for a package to be sent and received And it is not upgraded with high bandwidth beyond a certain margin. This delay, sometimes referred to as ping, takes time when we press the fire button and trigger the “headstock”, and does not change if the line is 150 Mbps, 300 Mbps or 600 Mbps (unless there are other differences beyond the bandwidth) .
