Wireless networking can be confusing. There are many numbers and letters being thrown around and with Gigabit Wi-Fi just starting to appear in mainstream devices, there’s more arcane info than ever to keep track of. Dual-band, 802.11, a,b,g,n,ac, 1300/1900, 600/900, 2.4GHz, 5GHz, beamforming... What does it all mean? In particular, what is the difference between the previous top performing Wi-Fi standard (802.11n wireless) and the new champ (802.11ac)? In this post, I’ll break it down to the basics.
