Hello, Everyone!
Today, I would like to share briefly with you an article on the types of WLAN protocols.
TCP/IP is a group of protocols, each with its own set of functions and goals. These protocols were developed by international standards organizations and are now utilized on practically all platforms around the world, allowing all internet devices to communicate successfully.
The 802.11 protocols have gone through numerous revisions, each one increasing the capability and speed of the previous generation. In majority cases, devices are capable of supporting multiple protocols. For example, 802.11ac/n/g equipment is compliant with three protocols.
Some of tthr Wireless local area network (WLAN) protocols, IEEE 802.11, and associated technologies, such as the 802.11X protocols are explained below:
1. Protocol 802.11ax (Wi-Fi 6)
802.11ax, often known as Wi-Fi 6, is the most recent edition of the 802.11 standards. Wi-Fi 6 supports OFDMA and MU-MIMO, allowing various devices to connect at the consecutively.
802.11ax outperforms previous versions of the protocol in terms of efficiency and security. It has a theoretical maximum transfer speed of 10 Gbps, which is 30% faster than Wi-Fi 5. 802.11ax allows backward-compatibility with other versions.
2. Protocol 802.11ac (Wi-Fi 5)
Dual Band functionality has been added to 802.11ac, generally known as Wi-Fi 5. It can use both the 2.4 GHz & 5 GHz bands at the same time. The 802.11ac protocol is nearly three times faster than the 802.11n protocol. In comparison to 802.11n, this protocol provides eight streams. Only the 5 GHz frequency is used by 802.11ac.
3. Protocol 802.11n (Wi-Fi 4)
802.11n uses MIMO technology and a wider radio frequency channel than its predecessors. It boosts a wireless local area network's speed and stability (WLAN). It supports both the 2.4 GHz and 5 GHz bands and has a speed of 600 Mbps, which is 10 times faster than 802.11g.
4. Protocol 802.11g
The 802.11g standard is a bit more advance from the 802.11b standard. It operates on the same busy 2.4 GHz band as other typical household wireless devices, but it is quicker, with transmission speeds of up to 54 Mbps. 802.11g equipment can still communicate with equipment running 802.11b protocol. Mixing the two standards, on the other hand, isn't typically a good idea.
5. Protocol 802.11a
The 802.11a standard operates on a different frequency spectrum than 802.11b standard. 802.11a devices have less competition and interference from domestic devices because they only broadcast in the 5 GHz band. 802.11a supports for transmission speed of up to 54 Mbps.
6. Protocol 802.11b
The 802.11b wireless standard was the first to be widely used in households and businesses. It is credited with the surge in popularity of hotspots and keeping connected while travelling because of its launch. Many PCs came with 802.11b equipment since it was reasonably inexpensive.
The 802.11b standard uses the uncontrolled 2.4 GHz frequency band. Unfortunately, many additional devices, such as cordless phones and baby monitors, can cause wireless network traffic to be disrupted.
802.11b transmissions have a maximum speed of 11 Mbps, which has been surpassed many times in recent versions of the protocol.
7. Bluetooth
Bluetooth is another well-known wireless protocol. Bluetooth devices transmit at a low power and have a limited range of about 30 feet. Bluetooth networks can link up to eight devices and use the unlicensed 2.4 GHz frequency band. The maximum transmission speed is 1 megabit per second.
In this burgeoning wireless networking area, there are a slew of other standards in the works. Do your research and compare the benefits of any new protocols against the expense of the equipment required for those protocols before deciding on the standard that best suits your needs.
