How to calculate your Wi-Fi bandwidth need
In this blog post, we will show you how to calculate your Wi-Fi bandwidth need, so as to rely on a well performing network experience.
Bandwidth refers to the rate of data transfer in a network and is measured in bits per second (bit/s). In order to rely on a fast and effective network, it is extremely relevant to know how many bits per second are transmitted across your network. Indeed, a low bandwidth implies slow connection and it negatively affects you network perfomance. Let’s see through a practical example the 3 steps to follow in order to effectevely measure your Wi-Fi bandwidth need.
1. Calculate how many devices will connect to the Wi-Fi at the same time.
If a hotel has 18 rooms, for 2 people each, the hotel has 36 guests if it’s full-booked. If each guest has 1.2 devices, you have around 43 devices in total. We can suppose that only 20 of 43 are connected at the same time.
2. Select the services that the guests expect to use.
|E-mail, instant messaging||Light usage|
|Web browsing||Light usage|
|Light / Medium usage|
|Upload photos||Medium usage|
|Skype||Medium / heavy usage|
|Google Drive, Dropbox…||Heavy usage|
|Video streaming (HD)||Heavy usage|
3. Calculate your bandwidth need
Number of concurrent devices (light usage) x 500 Kbps
Number of concurrent devices (medium usage) x 900 Kbps
Number of concurrent devices (heavy usage) X 2000 Kbps
We have 20 concurrent devices.
(10 X 500 Kbps) + (8 X 900 Kbps) + (2 X 2000 Kbps) =
5000+7200+4000 = 16200 Kbps = 16.2 Mbps
16.2 Mbps is our approximate Wi-Fi bandwidth need.
