An internet tốc độ test measures the connection tốc độ and quality of your connected device khổng lồ the internet. It does so by running multiple consecutive tests that analyze different aspects of your mạng internet connection, namely ping (latency), download speed, và upload speed. Each of these values represents the connection"s specific qualities, which you can read more about in the paragraph after the next. These should help you understand the final speed chạy thử results. But before we get to these, we first want khổng lồ discuss how lớn perform each test.

How to test tải về speed?

The tải về measurement is performed by opening multiple connections to a server and simultaneously starting the download of a large data file on all connections. This approach ensures that the entire bandwidth of the mạng internet connection is maxed out, và thereby the maximum data throughput can be measured. Recording the data throughput against measurement time finally yields the available internet speed for downloading data.

How to chạy thử upload speed?

Upload speed is tested by reversing the sequence of the download analysis. Again multiple connections are opened lớn the test server. Instead of downloading a file, a large tệp tin of random data is created on your device & pushed through all connections to the server. Pushing the data to lớn the vps over the network via multiple streams ensures that the maximum throughput is measured. Again, recording the data throughput against time yields the available internet speed for uploading data.

How to thử nghiệm ping?

During the ping test, the device sends a small data package over the network khổng lồ the thử nghiệm server on the internet. When the vps receives this package, it will send it back to the device, completing the roundtrip. The time it takes the data package to lớn complete the roundtrip is called latency, also known as ping. To achieve an accurate reading, multiple ping tests are conducted consecutively, with the final result being the average of all these tests.

All these are automatically handled for you when using But you should take one crucial aspect into account to chạy thử speed accurately. Choose the right tool. This depends on the device you want khổng lồ use, being a phone or tablet, or a computer. To kiểm tra internet speed on a computer, use your browser and the app on this website. To achieve accurate results on smartphone devices, you should tải về our ios or android app, respectively. This is especially important when running a WiFi tốc độ test. Because browsers on di động devices have poor performance, we suggest using a mobile app written in native code to lớn ensure the most accurate speed test results.

What is download speed?

The tốc độ at which your device can receive data from the internet. It"s calculated by dividing the total throughput of data in a given time frame by its duration. Therefore its unit is denoted by units of data over time. Most often, download speed is denoted in Megabits per second (Mbps or Mb/s), although other forms like Kilobits per second (Kbps or Kb/s) or Megabyte per second (MBps or MB/s) are also common.

What is upload speed?

As opposed to tải về speed, upload speed characterizes the amount of data your device can send khổng lồ the internet. It"s calculated the same way and is therefore denoted in the same units.

What is a ping (latency)?

The ping or latency describes the delay of a signal due to lớn the time it takes that signal lớn travel khổng lồ its destination. In this context, it represents the time it takes a data package to complete its roundtrip over the network và the acknowledgment from the vps that it was received. As a value of time, it is denoted as such, most often in Milliseconds (ms). It"s a value for the responsiveness of your connection.

Why should I test my internet speed?

Because knowing about your connection speeds enables you to lớn a) ensure that you get what you pay for from your mạng internet service provider và b) help you adapt your expectations about what type of applications you can run without issues on your network.

How fast is your internet?

It"s important to understand that different mạng internet speeds are necessary for different usage scenarios. So when you chạy thử internet speed, keep in mind that the question "How fast is my internet?" can only be answered in relation to what you want khổng lồ use the connection for. While simply browsing the website can be achieved with low single-digit megabit per second speeds, streaming Netflix in 4K resolution will need at least a 25Mbps connection speed. Online gaming will primarily be influenced by your ping, with a smaller ping being better while publishing content on the web, like uploading large videos to Youtube will be primarily constrained by your upload bandwidth.


AT&T is the oldest & largest telecommunication company in the United States with over 166 million subscribers. This number has more than doubled since 2007.

Verizon Wireless

With over 152 million subscribers Verizon Wireless is the second largest telco in the United States.

T-Mobile US

In earliy 2020 T-Mobile & Sprint merged their businesses with 86 million và 54 million respectively. The merger made the 3rd và 4th biggest telcos a similar kích cỡ as their two bigger rivals.
