Today, every  Home and business, owners have a WiFi Router and looking for a reliable suitable WiFi network  but Because of the rapid growth of this technology they face many sorts of acronyms for WiFi networks ( WiFi Standards ), they all basically mean a few things:

  • How far can the wireless signal reach
  • How much data can the signal send
  • Is it backwards compatible with other standards

To make it easier to understand, Just think how far can a network go, and how fast can it transmit data and the standards will make more sense.

Your WiFi Router , laptop, tablet, smartphone, and smart home devices all use different wireless standards to connect to the internet. Wireless standards rapidly changed every few years to bring faster internet, better connections and more simultaneous connections for users.

What is “WiFi” and “IEEE 802.11” ?

You may all have heard about the IEEE 802.11 and WiFi  standards, almost both have the same meaning but In the world of wireless, the term WiFi is synonymous with wireless access in general, WiFi is a specific trademark owned by the Wi-Fi Alliance, a group dedicated to certifying that WiFi products meet the IEEE 802.11 wireless standards.

WiFi Standards Body

Speed and Frequency are two fundamental changes in WiFi standards. Speed means How much data the network can transmit and Frequency means What radio frequency the network is carried on. These are either 2.4Ghz  and 5 Ghz.

Standards compatibility considerations in WiFi Routers:

  • 802.11ax WiFi Router is a dual band router(2.4 and 5Ghz bands)  and can communicate with 802.11b/g/n/ac/ax  clients.
  • 802.11ac WiFi Router is a dual band router and can communicate with 802.11b/g/n/ac clients.
  • 802.11n single band WiFi Router(2.4ghz band) can communicate with 802.11b/g/n clients in 2.4Ghz band.
  • 802.11n dual band WiFi Router(2.4 and 5Ghz bands)  can communicate with 802.11 b/g/n clients in 2.4 and 5ghz bands.
  • 802.11g WiFi Router(2.4ghz band) can communicate with 802.11b/g devices.
  • 802.11b WiFi Router(2.4ghz band) can communicate with only 802.11b devices.

New WiFi Standards Naming Convention

Over time, different classifications of WiFi networks were given different naming conventions. All of them are using the same scheme for example, 802.11ac as a router’s communication generation and 802.11k as a router’s communication capability (for roaming issues in enterprise WiFi networks) both using the same schema . as you see , it was a little confusing for users to understand and differentiate between them.

Recently , the WiFi standard has changed to a new classification, to help make it easier for consumers to understand , instead of understanding a whole alphabet combination, users can just look for “WiFi 4” instead of “802.11n or “WiFi 5” instead of “802.11ac” as what they need.
