# How to measure Wi-Fi speed? ### How to measure Wi-Fi speed?

The fastest, easiest and least painful way to measure flow of your Wi-Fi network is to use a free online in-browser test, such as Speedtest.net, offered by internet performance monitoring company OOKLA.

### How to calculate application throughput?

We arrive by approximating the following equation (see the course): E= 1/(1+(5.4*Tprop/Témis)) where Tprop is the propagation time and Témis is the emission time (Temis= Package size / debit). packet size for the Tprop calculated.

### How to calculate volume flow?

There is a second formula in which the volume flow is obtained by taking the product of the flow velocity (speed of passage of the fluid) by its passage section. Here is the formula: DV = Flow velocity (V) x Cross section (S) = S x V.

### What is the role of a router?

In addition to their routing function, routers make it possible to manipulate the data circulating in the form of datagrams in order to ensure the transition from one type of network to another.

### How to choose the cheapest route?

At each connection request the router chooses the least expensive route. Link state type routers (link state routing) listen to the network continuously in order to identify the various elements that surround it. From this information each router calculates the shortest path…

### How to calculate the maximum flow of a pipeline?

The maximum flow rate can be calculated by the following formula: The maximum flow rate in m3 per second is equal to the area of ​​your pipe diameter in m2, multiplied by the silent speed in meters per second. But still, How to calculate the diameter of a pipe?
