Provide at least two wireless LAN standards.

[Carlos Martes]

Ethernet is the most widely used LAN standard. It basically defines how devices in a local network communicate over cables, typically twisted pair or fiber optic. Ethernet uses packet switching to send data in frames and supports speeds from 10 Mbps up to several hundred Gbps in modern data centers. It also employs CSMA/CD which is Carrier Sense Multiple Access with Collision Detection, to manage network traffic in half-duplex mode, though modern Ethernet generally operates in full duplex, eliminating collisions. Ethernet is reliable, scalable, and forms the backbone of most wired networks worldwide. Wi-Fi is a wireless LAN standard that allows devices to connect without physical cabling. It operates primarily in the 2.4 GHz and 5GHz bands (with newer standards range from 802.11b to the modern Wi-Fi 6. This offers gigabit speeds, lower latency, and better performance overall especially in crowded environment’s. Wi-Fi is crucial for mobility and convenience in both terms of homes and enterprises. Question’s or concerns, please feel free to ask!

Hi, Carlos! Great work on describing the Ethernet as a LAN standard and Wi-Fi as a wireless LAN standard. These two standards achieve so much in the world of technology and networking. As you mentioned, the Ethernet has the importance of being a backbone for most wired networks, and Wi-Fi’s convenience of high speeds and mobility make it a valuable resource.

Have a great week! ~Dr. Anthony

But my God shall supply all your needs according to his riches in glory by Christ Jesus.
—Philippians 4:19
Man hungers for food, and God sends the sun and rain upon the golden fields of grain. The grain is made into flour, and flour into bread, and man’s physical hunger is satisfied. Man hungers for love; and God ignites the fire of affection in another heart, and two hearts are made complete in the bonds of holy matrimony.

Man hungers for knowledge, and God raises up institutions of learning, calls men to be instructors, puts it into the hearts of the rich to endow them; and men are satisfied in their thirst for knowledge. Man hungers for fellowship; and God allows him to build cities where men can share their industry, and their knowledge, and their skills.

Don’t tell me that God can supply man with an abundance of everything material and yet will let him starve spiritually! . . . God will satisfy the hunger and thirst of those who desire His righteousness because He loves the world with an undying affection.

Wireless LAN standards have changed greatly since the original, which only allowed 2 Mbps network speeds and limited device compatibility. Now, more WLAN standards have gotten new features and increased their speed capabilities. Two of the more recent ones to mention are 802.11ac and 802.11ax.

802.11ac, used in 2013, can maintain speeds up to 7 Gbps in the 5 GHz band. It has a great amount of throughput and uses channels with 80 MHz. 802.11ac also utilizes orthogonal frequency division multiplexing, or OFDM. In addition, it uses multiple input/multiple output (MIMO) to utilize antennas more efficiently (IEEE Standards Association, 2023).

802.11ax added the ability for the network to be apportioned across different devices (IEEE Standards Association, 2023). Compared to other standards, it has a better range outdoors and works better in crowded locations (IEEE Standards Association, 2023).

Great Summary! WIFI has really advanced. 802.11ac gave us faster speeds using 5 GHz and better antenna use with MIMO. Then 802.11ax improved things even more, letting networks handle more devices and work better in crowded areas. Both standards show how wireless keeps evolving to meet our needs. Nonetheless, great post Isabelle.
