What is Wi-Fi?
Wi-Fi is the most popular non-license wireless technology frequency used by computers, tablets, smartphones and many other devices. How did we get to this latest version Wi-Fi which is seven (7)?
This graph illustrate the progression of Wi-Fi since it was called Wireless Fidelity.
|Generation||IEEE Standard||Max Link Rate||Year Adopted||Frequency|
|Wi-Fi 7||802.11be||40,000||TBA||2.4/5/6 GHz|
|Wi-Fi 6E||802.11ax||600 to 9608||2020||2.4/5/6 GHz|
|Wi-Fi 6||802.11ax||600 to 9608||2019||2.4/5 GHz|
|Wi-Fi 5||802.11ac||433 to 6933||2014||5 GHz|
|Wi-Fi 4||802.11n||72 to 600||2008||2.4 GHz|
|Wi-Fi 3*||802.11g||6 to 54||2003||2.4 / 5 GHz|
|Wi-Fi 3*||802.11a||6 to 54||1999||2.4 GHz|
|Wi-Fi 3*||802.11b||1 to 11||1999||2.4 GHz|
|Wi-Fi 3*||802.11||1 to 2||1997||2.4 GHz|
How to know when to upgrade?
It depends on what is important for your organization or home and the type of usage that is common among the users. Usually an IT professional analysis can help you find that information from your existing network router. Most professionally structured networks will have data saved up about users’ behavior and network connection types (i.e. wired or wireless).
Consider These Before Your Upgrade Your Wi-Fi Generation
- Number of connected devices
- Type of usages
- Physical location
- Internet services type
- Network equipment hardware
- Location ethernet cable
You should know how much of the network speed is reduced by your Wi-Fi connection. Most importantly, how much speed reduces from various spots in the building. Information like this can be obtain through a Wi-Fi diagnostic.
Number of connected devices
The number of IP devices connected to your Wi-Fi can have a tremendous effect on the connection for users. Many households and companies now have printers, appliances, TVs etc… connected through Wi-Fi instead of wired. These equipment must be connected to the network but not necessarily wireless devices.
Type of Usage
Knowing the type of data used through the Wi-Fi is very important. This can help you understand how much dependence you have on your wireless network.
Your physical location plays an important role on the Wi-Fi performance. It can also limits your wireless network architecture design. If you are in a location where you share the available frequencies with many other wireless equipment, your wireless network must be designed according to this limitation. If you are in a location where all the 2.4 GHz and 5 GHz are readily available, you can design a network as you see fit. However, most businesses are located in the cities and suburbs. What that may mean to you, is that those businesses in your proximity share that 2.4 and 5 GHz frequency bandwidth which limits your frequency ability.
Businesses now cannot do anything online without security concern, that include wireless connection. If a hacker want to get into your network system, your wireless connection is usually a preferred choice. Your wireless network are always more securer with the update Wi-Fi generations
Know how much your can spend as it will affect every aspect of the infrastructure.
