What Is The Frequency Of 802.11a Networking

What is the frequency of 802.11a networking?

5.75 GHz is the frequency of 802.11a networking. The 802.11 has different types of the like 802.11a/b/g/n/ac. Currently, the 802.11 ac is the trending Technology right now. These have different theoretical speeds at 54 megabits per second, which is equal to the 6.75 megabytes per second. The IEEE 802.11 refers to the set of both layer 1 and layer 2 in a wireless local area network. If you want to know more about What Is The Frequency Of 802.11a Networking, keep reading this article till the end.

There is a five major difference that has evolved in the past years. 802.11b,802.11a,802.11g,802.11n,802.11ac. The combination of all these standards, we call it Wi-Fi. Each version is unique to itself but can share almost 3 common features between them. The different versions use the half-duplex signaling, the half-duplex can only transfer or receive the signals only one at a time.

It cannot do simultaneously both the transmissions at a time. It has the same band frequency from the range 2.4GHz to 5GHz. The layer 2 medium access control method can be known as the carrier sense multiple access. It can shortly be called the CSMA.

Let us understand the different features of each version of the 802.11 standards. The first established 802.11 has a low-frequency band with 2.4GHz and the speed of the frequency band is 1 to 2 Mbps. After years the 802.11b was established with the frequency band of 2.4GHz and a slightly greater speed of 11Mbps.

The 802.11b has very cost expensive. The 802.11a can use the high-frequency band with a range of 5GHz. The 802.11a is more expensive than the 802.11b and 802.11. Later, even the 802.11 a was replaced with the standard 802.11g with the frequency band of 2.4GHz and with a speed up to of 54Mbps per second.

The 802.11 n was coming into the world after the 802.11g, it can use both 2.4GHz and 5GHz frequency bands with a speed of 65 to 600Mbps. Now, the 802.11ac is the new Technology with a new frequency band of 5GHz and up to a speed of 7gigabit per second.
