Wireless Networking: A Comparison & Contrast of Protocols

Alas, dear reader, we've embarked on a journey to understand, compare, and contrast the protocols for wireless networking - an essential chunk of knowledge for the CompTIA A+ Core 1 (220-1101) exam. Fasten your seat belts because we're about to dive into the thrilling world of networking protocols, avoid the jargon potholes, and take a scenic route that is as enlightening as it is interesting. But fret not, this isn't a one-way ticket to boredom; we will navigate through all these terminologies and concepts as if we are acquaintances catching up over a cup of coffee.

First off, let's butter up our crumpets of knowledge with a brief rundown of what wireless networking protocols are. These are sets of rules that determine how data is transmitted and received in a wireless network. Without these protocols, our online world would be as confused and chaotic as a fish market on a Monday morning. Now that you and I are in sync, we will dissect the comparison and contrast of these fascinating protocols.

A Peek into the Protocols

In the pulse-pounding world of wireless networking, 802.11a, 802.11b, and 802.11g stand as the three musketeers. We shall dive in and discern the unique characteristics of each protocol, shall we not?

802.11The eldest protocol, a, prides itself on a maximum speed of 54 Mbps and operates on a 5 GHz frequency. Its high frequency, while a speed demon, can't go through walls, making it a bit of a homebody. Then there's 802.11b, a protocol as sturdy as an oak tree that trades off speed for range. It operates at 2.4 GHz, allowing it to penetrate walls but with a reduced speed of 11 Mbps. Last but not least, 802.11g, the Goldilocks of the three, balances speed and range beautifully. Like a network ballerina, it operates at 54 Mbps and on the 2.4 GHz frequency, showing it has the best of both worlds.

By the Numbers: A Statistical Analysis of Wireless Protocols

Now, you didn't think I'd leave you high and dry without some juicy statistics, did you? My oh my, of course not! According to data from OpenSignal, in 2018 the global average speed for 802.11g hovered around 26 Mbps. Even though capable of achieving speeds up to 54 Mbps, factors like network congestion, interference, and numerous connected devices often hamper real-world usage.

Meanwhile, the Wi-Fi Alliance's 2020 report revealed that people were adopting 802.11ac, the newer protocol termed as 'gigabit Wi-Fi', at an alarming rate due to its superior speeds and reliability. This Wi-Fi protocol lets you milk an impressive speed upwards of 1300 Mbps on the 5 GHz band. That surely gives you a great bang for your buck, right?
