What is 802.11 ac and ax


What are 802.11ac and 802.11ax?

802.11ac and 802.11ax are very important standards for networking and Wi-Fi usage. Both these standards have been created by the IEEE (Institute of Electrical and Electronic Engineers). It was created to increase the speed and performance of Wi-Fi networks.


Introduction to 802.11ac :-

Wi-Fi 5 is also known as 802.11ac. It is a standard of Wi-Fi technology that runs on the 5 GHz band. It is used to increase high data transfer and performance.


Features of 802.11ac :-

1. High data rate: The 802.11ac standard increases high throughput to 1.3 gigahertz per second (Gbps). It is much faster than 802.11n. It is used for high-speed data downloads and for streaming and gaming.

2. Wide channel bandwidth: It uses 802.11ac 80 megahertz (MHz) and 160 MHz channels to send data at the same time. It works with high throughput.

3. Multi-user MIMO (MU-MIMO): It uses the 802.11 ac standard multi-user MIMO to send data to multiple devices at the same time. Using this, data can be communicated with multiple devices in the network.

4. Beamforming: 802.11ac uses beamforming technology to send signals towards a single device. It improves range.


Introduction of 802.11ax :-

802.11ax is known as Wi-Fi 6. This technology of Wi-Fi runs in both 2.4 GHz and 5 GHz bands. It gives high efficiency and very good performance.


Features of 802.11ax :-

1. High capacity: 802.11ax increases the maximum throughput to 10 gigabits per second (Gbps). 802.11ax works to send data with high bandwidth.

2. OFDMA: 802.11ax uses OFDMA (Orthogonal Frequency Division Multiple Access) technology. 802.11ax works to send data to multiple devices on the same channel. Due to this, the efficiency of the network improves.

3. Target Wake Time: 802.11ax uses TWT (Target Wake Time) technology. Due to which the device gets data as per its requirement. Its use saves battery and reduces power consumption.

4. Beamforming: 802.11 ax beamforming technology is used to send a signal towards a single device. Its use increases the range of the signal.

5. UL & DL MU-MIMO: Multi-user MIMO is used in 802.11 ax uplink and downlink. Its job is to send data to many devices at a time. This improves the efficiency of the network.

6. BSS Coloring: 802.11 ax uses BSS (BASIC SERVICE SET) to reduce network interference. Its use improves the efficiency of the signal.


Difference between 802.11ac and 802.11ax :-

1. Data rate: 802.11ac has a higher data rate of up to 1.3 Gbps. And compared to 802.11ac, 802.11ax has a higher data rate of up to 10 Gbps. Therefore, 802.11ax is used more because the speed of sending data in it is very high.

2. Channel bandwidth: 802.11ac uses 80 MHz and 160 MHz channels. And 802.11ax uses 2.4 GHz and 5 GHz bands.

3. Multi-user MIMO: 802.11ac uses multi-user MIMO on a single downlink. And 802.11ax works in both uplink and downlink.

4. Battery life: Using 802.11ac consumes more power. And 802.11ax uses target wake time, due to which 802.11ax consumes less battery power. This improves battery life.

5. Network efficiency: 802.11ax uses OFDMA and BSS coloring to improve efficiency in the network. Whereas 802.11ac does not have any such features.


Conclusion :-

Both 802.11ac and 802.11ax technologies are very important for using Wi-Fi. Both of them are used for networking. 802.11ac gives a high data transfer rate as Wi-Fi 5. And 802.11ax improves high efficiency and battery life as Wi-Fi 6. Both the technologies should be used as per your need.

Common network issues and solutions in computer networks

Common network issues and solutions in computer networks:- Computer networks are an important part of modern organizations. Data is sent and received using it. And it is used for communication and connecting resources. It is necessary to fix the problem of the network. So that the functionality of the network can be increased and made efficient. 1. Connectivity problems :- Problem: If a user is unable to connect to the network. Solution:- Reboot the computer and router: If the user is unable to connect to the network, then he can connect to the network by resetting the circuit first. Check the network cable and connection: if the user is unable to connect to the network. Then check the network cable to see if the network cable is connected correctly or not. And whether the network cable is broken or not. Check the settings of the network adapter: If the user is unable to connect to the network. Then check if the network adapter is connected correctly or not. Check IP address: If the ...

What are the troubleshooting methodologies

Network Troubleshooting Methodologies: Network Problem Solving Techniques :- Network problem solving is an important task whose purpose is to identify the network problems and fix them. Therefore, this process demands technical knowledge and use of the right tools. Network management, network engineers, and IT assistants are responsible for identifying and solving network problems. In this article, network troubleshooting and methods will be explained. Problem identification :- The first step in network problem solving is to identify the problem. Many steps have been taken for this: 1. Network monitoring: Any unusual activity occurring on the network can be identified using network monitoring tools. These tools monitor the availability, performance, and security of the network. 2. User reports: It evaluates the problems and complaints received from the users. Then it is known where the problem is occurring in the network. 3. Log File Analysis: Evaluates the log files of network devi...

What is a firewall

What is a firewall: An integral part of computer security :- In the context of computer and network security, a firewall is a special device that prevents unauthorized access and helps to secure data. And it restricts network traffic and only allows data coming from reputable sources. Therefore, through this article, the types of firewalls, definitions, benefits, and their functions and rules for implementing them will be explained. Definition of firewall (structure):- A firewall is a security system that has been created to keep the network safe. Its main goal is to block unauthorized traffic and allow only the traffic that comes with the right credentials. It filters network traffic and monitors the data coming and going in the network. Types of firewall :- There are two types of firewalls: software firewalls and hardware firewalls. Apart from this, there are other types of network security. 1. Software Firewall: A software firewall is a program that is applied to a computer or netwo...
