How Do Upload and Download Speeds Relate to Speed Advertised by Isp
Judging by the amount of searches washed for the term "speed exam" there seems to exist a bit of an obsession with Net speeds.
In that location are many online test tools that allow yous to cheque your upload and download speeds.
In this tutorial I will try to explain how speed tests work and what they are actually telling you. We look at.:
- What is a skilful download speed and upload speed?
- What does Mbps mean?
- Is a download speed of 10 Mbps good? How fast is 10 Mbps
- Does Internet speeds vary throughout the mean solar day.
- Is it worth irresolute providers to get a faster internet connection?
Understanding Net Speed Tests
Net speed tests will requite you lot an upload speed and download speed.
Uploading refers to the procedure of transferring data from your figurer to the Internet, and downloading refers to transferring data from the Internet to your figurer.
Commonly the download speed is much greater than the upload speed (ADSL).
This is commonly OK because for most people they download much more than they upload.
Download speed tests work by transferring a file of a known size from a test server located on the Net to your calculator, and measuring how long it takes.
A iv MB file will take 8 secs over a 4 Mbits/due south link and 2 seconds over a 16 Mbits/s link. (see Bits and Bytes).
The upload speed is measured by uploading a file from your PC to the test server and once more measuring the time taken.
There are many online test tools yous might want to endeavor these:
- http://world wide web.speedtest.internet/
- http://diagnostics.bt.com/login/?workflow=Speed
- http://www.bbc.co.uk/iplayer/diagnostics
There are several factors that affect how fast your overall connectedness speed is:
- The admission applied science- e.g. ADSL,4G/3G mobile, Satellite etc
- Your ISP.
- The location of your destination server or service.
They all combine together to class a chain (communications link) . As a comparison, If you imagine traffic driving down a half-dozen lane route, which becomes a two lane road and.then a four lane road. (image Below).
.
You tin see that the traffic will be restricted by the 2 lane road.
On the Internet, just like on a normal route, your final speed will be express past the slowest link in the concatenation.
Note: You lot do not demand to install any software on your figurer to practice a Internet speed test. Be very wary when using speed test sites as some with prompt you to install software to ameliorate your computer speed. Some probably are 18-carat, merely information technology is impossible to tell, so I wouldn't practice information technology.
Internet Speed Factors
Several factors affect your internet access speeds:
- Your Access technology
- Your ISP
- Location of the remote resources
- Time of Twenty-four hour period
Internet Access Technology
This is the most important factor as far as net access speed is concerned.
All technologies have limitations. The connexion speeds of fiber broadband is far superior to 3G mobile.
See common Cyberspace admission methods. for an overview with pros and cons of each engineering science
Your (Internet service provider) ISP
Yous connect to your ISP (using an access method eastward.m. ADSL Broadband) and your Internet service provider then connects to the Internet.
ISPs advertise the connection speeds to the subscriber, and not the speeds between the subscriber and the Internet.
In the UK the connectedness to the home is almost always a BT phone line and ADSL, only fibre is becoming increasing popular.
If that is the case and then The admission speed will exist limited past these BT lines regardless of the Internet access provider you choose.
However that doesn't mean that all providers volition provide the aforementioned overall connection quality every bit-.
The connection between the Internet access provider and the Internet is usually over fiber and is fast, but it is shared by many subscribers.
Therefore if the Internet access provider overloads the link to the Internet it slows the connection from subscriber to Net.
So your Connection to the ISP could be 6Mbits/s but from you to the Net information technology could be only 3 Mbits/southward.
Here is a quote from the BBC article on broadband speeds
Nigh half of broadband users are now on packages with advertised speeds above 10Mbps simply the boilerplate broadband speed is 6.8Mbps co-ordinate to Ofcom.
The Location Of The Service/Server On The Internet
The Internet comprises a vast network on interconnected computers and networking equipment due east.thousand routers (diagram below).
The number of routers/servers that the information must travel through on the fashion to and from the destination service/server will affect the overall speed.
In addition the speed and capacity of the network that inter-links these computers/routers volition likewise impact the final connection speed.
In general the Net itself will oftentimes be the limiting factor that affects your overall internet speed.
And then you may have a super fast connectedness to the Internet, simply even so accept the same amount of time to download a file from the Internet every bit someone with a much slower Internet connection.
Fourth dimension of Day
You may accept noticed that the Internet appears to boring at certain times of day.
This is very like to blitz hr on the roads.
Hither is a uswitch graph showing Internet speeds in the Uk over the day.
Discover how the boilerplate speed drops from almost 10Mbps to around 6Mbps.
The worst fourth dimension to be surfing the net is between 7pm and 9pm.
When doing speed tests it is a good thought to exercise several over the course or a normal mean solar day.
Download vs Upload Speeds
When you view a website with a web browser you are downloading information from the Internet.
Most people spend most of the fourth dimension surfing the Internet, and downloading information, which is why the download speed is normally more important than the upload speed.
It is the speed that broadband providers commonly display, and what people compare.
Here is a screen shot of the standard BT broadband package, and observe at that place is no mention of the upload speed.
If you send email and then that e-mail is uploaded from your PC to the Cyberspace.
If you post pictures or videos on YouTube or Facebook and then those pictures/images are uploaded to the Internet.
How long that takes will depend on the upload speed of your connection.
Almost broadband packages provide broadband over phone lines, and use a technology called ADSL (Asynchronous Digital Subscriber Line ) which has a much faster download speed than upload speed.
If you take an existing broadband connection you lot can check your upload and download speeds using an online speed tester. Here are my results:
Notice that the upload speed is 21 times slower than the download speed. This means that a file that could be downloaded from the net in 30 minutes would take over ten hours to upload to the Net.
Most Cyberspace users aren't currently interested in uploading files to the Net, but with the growth in popularity of online storage there could be a increment in demand for much faster upload speeds.
The newer fiber packages from the main United kingdom of great britain and northern ireland broadband providers (BT, SKY, Virgin,Talk Talk) offering significantly faster upload speeds as well equally faster download speeds
The screen shot below shows the BT Infinity package with a download speed (76Mb) , which four times faster than the upload speed (19Mb).
If y'all are considering using the Internet for transferring big files and so yous should look for a broadband bundle that offers fast upload speeds.
What is a Good Upload or Download Speed?
This really depends on what you lot want to do with the Internet connection.
If you desire to download and stream movies then a minimum of 4Mbps is needed.
If there are several people in your household that too lookout man movies online and so you would want a footling more speed.
The best indicator of slow network speeds is obtained by using the Net.
If y'all find that that web pages take a long time to load, and movies take a long time to buffer, then you should cheque your speed.
An easier check is to check your Isp advertised speeds against your own speed.
You might find that you are paying a premium for a package because of the advertised speed but it is impossible for you to go those speeds because of your location.
Internet Speed Checkers
They are many websites that allow you lot to check your Internet speed similar this online speed tester.
However if you want to monitor your Net speed on a regular basis then I recommend the command line to;; chosen speedtest-cli.
This Github page equally the install and usage instructions
Summary
Speed tests are useful for checking that y'all aren't paying for a connexion that you lot aren't getting.
Even so your connection speed is only one part of the overall Cyberspace connection, and yous are unlikely to notice the difference between a 10Mbit/s connection and a 6Mbit/s connection when watching, for example, a YouTube video.
The more people you have accessing the Cyberspace through your connection the more of import your connection speed becomes.
Bits and Bytes Explained
A byte has 8 bits. The size of files stored on your computer is measured in bytes.
iKB =ane kilo Bytes =1,000 Bytes and 1MB=1 One thousand thousand Bytes.
When measuring data transmission speeds the measurement is bits per second or bps
Once more
1 kbps =1 yard bits per 2d and 1Mbps= 1Million bits/sec
Notice $.25 has small b and bytes a big B.
Common Questions and Answers
Q- I measured by upload and download speeds and they are very different to what the broadband provider advertised. Is this normal?
A- Yes. ISPs usually quote the best speeds possible in theory, but not in practice.
Q- I measured by download speed and it is XMbps is information technology fast enough?
A- Information technology depends on what y'all practise, or desire to do with the connection and how many people use the connexion. By and large speeds above half-dozen-8 Mbps will be skilful for most applications.
Q- My Net connexion is slow what is the reason?
A- It is difficult to say for certain. It could be your connexion to your Isp or information technology could be the Internet. If you check your connection and find that your download speed is effectually 6Mbps or faster then it is likely to be the Internet.
Q- Is it worth changing providers to get a faster internet connection?
A- Because of the style broadband is provided information technology is usually improve to attempt changing the access method i.e. go to cobweb instead of ADSL.
Q- Can my Wi-Fi be responsible for my low speeds?
A- Yes if you are using old Wi-Fi adapters in your laptop/PC. For example the sometime 802.11a standard peaked at effectually 5Mbps. Run across this Yahoo reply and this well-nigh google support tip for details
Q- I am using Cloud storage for backing upwards data what should I check?
A- You demand to bank check your upload speed. Generally but fibre broadband supplies good upload speeds.
Q- Is 6 Mbps fast?
A- Yous tin judge it'due south speed by how long it takes to transfer data. A 6 MB file will take 8 secs over a six Mbits/south. A standard 1GB motion-picture show will take about 22 minutes to download at 6Mbps.
Q- What is more than important upload speed or download speed?
A- For almost people it will exist the download speed as well-nigh people will be browsing the web downloading movies etc.
