Different types of wifi types

Hello friends, today I want to share my first experience regarding wifi.

so at the beginning of that year I wanted to install wifi using a fixed broadband service, in my mind to make the wifi speed faster and also be able to share it with several devices, I immediately searched for products in the green shop and orange shop. At the green shop I found a product that I thought wow.. this is murmer (aka cheap) I just checked out immediately and normally and chose the available shipping services and made the payment.

Long story short, the package has arrived. I immediately tried and did the installation according to the manual.

And wow… the internet runs smoothly, wifian streaming is also okay.

A week has passed, and the problems began to be felt. that is, when wifi devices are used together, maybe up to 12 more devices, consisting of mobile phones, smart home, smart tv, pc, laptop, how come it starts to stutter or have a lot of lag (if it’s pinged it keeps showing RTO = Request Time Out) asd

Then I searched on the internet, it turns out that my wifi is categorized as wifi 4 or can receive frequencies in band a/b/g/n, while the most recent (at the moment) is wifi 6.

Here I share information about wifi technology version 1 to 6:

Wifi is apparently an abbreviation. It stands for wireless fidelity, a wireless network technology certified by the Wi-Fi Alliance. This technology allows an area to have a wireless internet network, so one device can connect to the internet without using a wired LAN network. To connect, it is clear that the device must support wifi technology.

Today’s devices themselves certainly support wifi networks. It’s just that each device with other devices usually has a different type of wifi. You may not notice this, but if you are observant, you can find this type of wifi with the 802.11 code.

Why use 802.11 codes? Because wifi as a network is very broad and needs to be certified. Well, the certification is carried out by the IEEE 802.11 platform wifi. IEEE itself is an organization that regulates the development of standardization of communication technology

This organization, which consists of professionals, sets various communication technology standards. Especially those dealing with wifi certification, the code is 802.11. This code refers to the standardization of wifi communication with various types. Meanwhile, the various types of wifi that are widely used on cellphones are as follows.


1. 802.11b (wifi 1 – 1999)

802.11b is a type of wifi that runs on irregular radio signals. Due to its irregular nature, this network can interfere with various types of equipment such as microwave ovens or other devices on the same frequency as 802.11b, namely 2.4 GHz. 802.11b is a type of wifi that has lower data rates than 802.11a. However, the 802.11b signal range reaches only 30 m which affects the signal range for better reception.

2. 802.11a (wifi 2 – 1999)

If you find a cellphone with wifi 802.11a support, this means that the cellphone can work at a frequency of 5 GHz. Devices that support this network have a SATA transfer speed of up to 58 Mbps. This wifi speed is relatively fast, but there is one drawback, namely the signal obtained is usually short and it is easier to be late.

3. 802.11g (wifi 3 – 2003)

If you have a cellphone that supports 802.11g type wifi networks, then you are in luck because this technology is better than 802.11a and 802.11b types. In a way, 802.11g is a wifi technology that combines the advantages of 802.11a and 802.11b.

The 802.11g standard uses the same frequency as 802.11b, namely 2.4GHz, but the data transfer process is not as slow as 802.11b but as fast as 802.11a, namely 54 Mbps. For this reason, devices using 802.11g have maximum speed but have good and unobstructed signal reception. In addition, 802.11g has access point compatibility with 802.11b.

4. 802.11n (wifi 4 – 2009)

802.11n is a better networking standard than 802.11g. This type of wifi is an improved version of 802.11g in terms of speed because it is able to take advantage of wireless signals and antennas. It’s not strange, if this type of wifi has a data transfer rate of up to 100-200 Mbps.

Besides being fast, 802.11n has good signal coverage and is more resistant to various interference signals from various outside sources. Wifi 802.11n is also compatible with 802.11b and 802.11g because they are on the same frequency, namely 2.4 GHz.

5. 802.11ac (wifi 5 – 2014)

802.11ac is a type of wifi that has a frequency of 5 GHz. This means that this type of wifi is compatible with 802.11a which is on the same frequency. As for the data speed, this type of wifi can reach 1.3 Gbs, many times faster than 802.11n.

The speed that 802.11ac has is probably because this type of wifi has a wider channel (80 or 160 MHz versus 40 MHz) in the 5 GHz band. Therefore, cellphones that have this type of wifi have good wifi signal reception.

6. 802.11ax (wifi 6 – 2019)

802.11ax is a type of wifi that is the successor of 802.11ac. This type of wifi still uses the band at the 5 GHz frequency. It’s just that the speed of this wifi can reach 3.5 Gbps, which is clearly faster than 802.11ac.

With data transfers that are so fast, this cellphone that supports wifi networks can do things like stream 4K videos, download games with large sizes, and even access various devices without latency. In addition, this technology allows a device to be connected to four other devices simultaneously via Multi Input Multi Output(MU-MIMO).

The interesting thing about the 802.11ax standard is support for the previous generation of Wi-Fi tips, namely the 802.11a / b / g / n / ac standard. 802.11ax itself has been implemented on high-end cellphones.

That’s all the information I got. hopefully useful for you..
