WiFi frequency

Wi-Fi stands for wireless fidelity uses two frequency bands available to use when setting up Wi-Fi network.

• 2.4 GHz
• 5 GHz

So now let us talk about where and which types of frequency most widely used in daily life.

In general 2.4 GHz is the most universally used frequency. 2.4 GHz is the most compatible with standard for building a wireless network known as 802.11b and 802.11g.

This frequency most common one, because it can result in device interfering with each other.

5 GHz is less common, It is range about 30 meters. Result is not good too much compare to 2.4 GHz. But sometimes it achieve high speed reason of less crowded frequency.

5 GHz is the most compatible with standard for building a wireless network known as 802.11a and 802.11n.

Now let us check it out some advantages and disadvantages of 2.4 GHz frequency and 5 GHz frequency :

2.4 GHz :

Advantages :

• Accessible from greater distance
• Compatible with lots of devices

Disadvantages :

• Crowded frequency from all the device that supports 

5 GHz :

Advantages : 

• Lots more bandwidth
• Generally less interference on 5 GHz because the frequency is not as crowded

Disadvantages :

• Available for shorter distances
• Not compatible with as many devices 

WiFi bandwidth

Wi-Fi stands for wireless fidelity uses two frequency bands available to use when setting up a Wi-Fi network.

How to set up 20 MHz or 40 MHz bandwidth?

In this article, we will go over some simple rules to help you decide the best bandwidth to use for the wireless network.

How we can choose 20 or 40 MHz?

This answer is very simple it can only depend on the devices that you have in your house. The best radio broadcast can be found without 2.4 GH vs 5GHz wireless guide.

When we have to use the 2.4 GHz frequency. you should use 20 MHz for channel width because of it is really a supportive measure for your older device.

When we have to use the 5 GHz frequency. you should use 40 MHz bandwidth. So we can use 5 GHz frequency, the network consisted of the latest device that supports 802.11n.

When we can use of 20 MHz / 40 MHz combination if one of your devices require it. If not required, just set it to 40 MHz.

Feature of WiFi

Wi-Fi stands for Wireless fidelity is an alternative to wired technology that is commonly used for connecting devices in wireless mode. There is numerous application of Wi-Fi in different areas because of some useful feature of Wi-Fi. So now let us check the features of Wi-Fi one by one below :

Features of Wi-Fi :

• While using Wi-Fi there is no limitation
• Faster and secure
• Unmatched mobility
• Fortress technology
• No need for cabling
• Secure interment connection for feature
• It's convenient and everywhere
• It is a scalable and robust system
• Great power consumption
• The easy way of network installation
• The configuration of the device is very easy
• If we are nearer to Wi-Fi hotspot  network then you will automatically connect internet 

WiFi technology

Wi-Fi network uses radio technologies to transmit and receive data at high speed. 

These are governed by some set of the standard given below :

1. IEEE 802.11b
2. IEEE 802.11a
3. IEEE 802.11g

1. IEEE 802.11b

• It was formulated in the year 1999
• It operates at 2.4 GHz radio spectrum
• The actual speed is 4-6 Mbps
• It supports a range from 100-500 feet
• It is a very popular Wi-Fi technology and is the least expensive
• It has a theoretical speed of 11 Mbps within 30 m range

2. IEEE 802.11a

• It was introduced in 2001
• It operates at 5GHz with theoretical speed 54 Mbps
• It is the most expensive technology and hence reduce its popularity
• It is actual speed varies from 15-20 Mbps in a range of 50-75 feet
• It is not compatible with IEEE 802.11b

3. IEEE 802.11g

• It was introduced in 2003
• It was improved version with inherent advantages of 802.11a and 802.11b specification
• It operates at 2.4 GHz radio frequency
• It has a speed of 54 Mbps and covers a range of 100-150 feet
• It is compatible with IEEE 802.11b

Advantages and disadvantages of WiFi

Wi-Fi is term full form of Wi-Fi is Wireless fidelity is an alternative to wired technology that is commonly used for connecting devices in wireless mode. Wi-Fi network device connects computers to each other to the internet and to the wired network.
