5.925–7.125 GHz in the US, a band 1.200 GHz wide).[8]. The main goal of this standard is enhancing throughput-per-area[a] in high-density scenarios, such as corporate offices, shopping malls and dense residential apartments
What are 802.11ax, 802.11ac, 802.11n (Wi-Fi 6, Wi-Fi 5, Wi-Fi 4)? [3]
We live in the internet age, and almost everyone has a wireless router in their homes, helping families stay connected at all times. While Wi-Fi is a frequent term in our vocabulary, the names of the different wireless networking standards are challenging to understand and even pronounce
Do you know what 802.11ax is? What about 802.11ac or 802.11n? To help you, I explain these terms and share the basics you need to know about each Wi-Fi standard, how they differ, and the real-life performance each of them delivers. Read this article to find the information you need:
802.11n is also referred to as Wi-Fi 4, and it’s the first standard to allow the use of two radio frequency bands: 2.4 GHz and 5 GHz. The 5 GHz band is an optional component of Wi-Fi 4, and manufacturers ignored it on many of their routers to keep costs down
WiFi Network Standards Compared: 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a [4]
WiFi Network Standards Compared: 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a. 802.11ac is the latest WiFi standard and uses the 5.8GHz frequency band
802.11AC is the latest standard and has six major improvements over 802.11n that result in much higher throughputs:. – Uses 5GHz band, which is much less congested than 2.4GHz: 802.11n runs on the heavily overused 2.4GHz which is prone to interference from the many devices on this spectrum
A quality Wi-Fi antenna fitted to a 5GHz router improves its range within usable distances. – 80MHz channel: 2x the width of 802.11n: 802.11n can only support a 4X40MHz bandwidth compared to 802.11ac’s 8X160Mhz
IEEE 802.11 [5]
IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer communication. The standard and amendments provide the basis for wireless network products using the Wi-Fi brand and are the world’s most widely used wireless computer networking standards
IEEE 802.11 is also a basis for vehicle-based communication networks with IEEE 802.11p.. The standards are created and maintained by the Institute of Electrical and Electronics Engineers (IEEE) LAN/MAN Standards Committee (IEEE 802)
While each amendment is officially revoked when it is incorporated in the latest version of the standard, the corporate world tends to market to the revisions because they concisely denote the capabilities of their products. As a result, in the marketplace, each revision tends to become its own standard.
Explain Wireless Ethernet Standards [6]
IEEE 802.11 is the standard that specifies connectivity for wireless networks. IEEE 802.11, or Wi-Fi, refers to the collective group of standards—802.11a, 802.11b, 802.11g, and 802.11n
■ 802.11a: Devices conforming to the 802.11a standard allow WLANs to achieve data rates as high as 54 Mbps. IEEE 802.11a devices operate in the 5-GHz radio frequency range and within a maximum range of 150 feet (45.7 m).
These devices operate within a maximum range of 300 feet (91 m).. ■ 802.11g: IEEE 802.11g provides the same theoretical maximum speed as 802.11a, which is 54 Mbps, but operates in the same 2.4-GHz spectrum as 802.11b

802.11x: Wi-Fi standards and speeds explained [8]
The term Wi-Fi is synonymous with wireless LANs, despite the fact it’s a specific trademark owned by the Wi-Fi Alliance, a group dedicated to certifying that products meet the IEEE’s wireless standards.. In the IEEE’s naming convention, all standards that specify protocols for implementing wireless LANs fall under the 802.11umbrella
Thanks to the widespread acceptance of wireless LANs, new standards continue to be developed at a rapid pace, creating a confusing alphabet soup.. In an effort to help the general public understand the standards a bit better, the Wi-Fi Alliance in 2018 began translating the technical names of standards into an easy-to-remember numerical system (Wi-Fi 5, Wi-Fi 6) that mirrors the way that cellular technologies are named (3G, 4G, 5G).
You can also view a timeline of these standards at the IEEE website.. Older home wireless routers are likely 802.1ac compliant and operate in the 5 GHz frequency band

The Network+ objectives focus on 802.11, 802.11a, 802.11b, 802.11g, and 802.11n. All these standards use the Ethernet protocol and the CSMA/CA access method.
All standards can use either an infrastructure or ad hoc network design, and each can use the same security protocols. Ad hoc and infrastructure wireless topologies were discussed in Chapter 1.
802.11 Wireless Standards Explanation and Comparison [12]
In the current digital world, Wi-Fi is an all-catch term often synonymous with wireless internet access. However, unknown to many, it is a specific trademark that belongs to Wi-Fi Alliance, a group that certifies that all Wi-Fi products meet IEEE 802.11 standards
These wireless standards frequently change, with new updates bringing faster Wi-Fi speeds and better connections. Before looking at the 802.11 standards comparison, the 802.11 standards chart below will ease differentiating various 802.11 Wi-Fi standards.
The version supports a maximum connection speed of 1Mbps. Unfortunately, devices using this version are no longer produced and don’t work on today’s equipment.
The Evolution of 802.11 WiFi standard to WiFi 6E 6Ghz [13]
The world of WiFi has evolved greatly since first being introduced to consumers in 1997 – both in terms of speed and capability, as well as naming and positioning. The initial consumer WiFi offering was based on the IEEE 802.11 standard, and subsequent versions were named based on their updates and amendments to capabilities, for instance 802.11b or 802.11g
Today we are on the cusp of the next phase of great for wireless connectivity via WiFi 6E – but understanding how we got here can allow us to appreciate all that WiFi 6E delivers today.. WiFi certainly took the world by storm, with consumers and businesses realizing the benefits of increased Internet connectivity and capabilities.
Using 2.4 GHz frequency, 802.11b supported a maximum theoretical rate of 11 Mbps with a range of 150 feet. Additionally, the components of 802.11b were inexpensive – making the technology more accessible to consumers

When to Use 802.11 a, b, g, b, nc: WiFi Standards [16]
When the Wi-Fi Alliance came up with Wi-Fi Generations labels, they made sorting through the different 802.11x standards a little easier. Intuitively, you can infer that Wi-Fi 5 (802.11ac) is faster and newer than Wi-Fi 4 (802.11n)
However, while those labels help, they don’t tell you everything you need to know about when to use the different 802.11x standards.. CBT Nuggets trainer Jeff Kish has a primer on Wi-Fi 6 in this Trainer Talk:
There have been plenty of 802.11x standards since the original 802.11-1997. Before we explore which Wi-Fi standards you should use, let’s take a look at what those standards are
Wireless LAN 802.11 Wi-Fi [17]
The general IEEE designation for network standards in “802”, eg IEEE 802.3 for Ethernet. The “11” family of standards governs wireless local area networking
The 802.11 family currently includes six over-the-air modulation techniques that all use the same Layer 2 protocols, the most popular (and prolific) techniques are those defined by the a, b, and g amendments to the original standard; security was originally included, and was later enhanced via the 802.11i amendment. Other standards in the family (c–f, h–j, n) are service enhancement and extensions, or corrections to previous specifications
IEEE 802.11b and 802.11g standards use the unprotected 2.4 GHz frequency band. Operating in an unregulated frequency band, 802.11b and 802.11g equipment suffer interference from microwave ovens, cordless phones, and other appliances using the same 2.4 GHz ISM band.
