2008. This article presents a tutorial/discussion of three commonly-used IEEE 802.11 wireless network security standards: WEP, WPA and WPA2.
What 802 standard is focused on wireless security?
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.
What are the 802.11 wireless standards?
Table 7.5. 802.11 Wireless Standards
| IEEE Standard | Frequency/Medium | Speed |
|---|---|---|
| 802.11a | 5GHz | Up to 54Mbps |
| 802.11b | 2.4GHz | Up to 11Mbps |
| 802.11g | 2.4GHz | Up to 54Mbps |
| 802.11n | 2.4GHz/5GHz | Up to 600Mbps |

What are the wireless security standards?
Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. … The most common type is Wi-Fi security, which includes Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). WEP is an old IEEE 802.11 standard from 1997.
Which 802.11 mode is fastest?
If you’re looking for faster Wi-Fi performance, you want 802.11ac — it’s that simple. In essence, 802.11ac is a supercharged version of 802.11n. 802.11ac is dozens of times faster, and delivers speeds ranging from 433 Mbps (megabits per second) up to several gigabits per second.
What is the best type of 802.11 wireless security?
When choosing from among WEP, WPA, WPA2 and WPA3 wireless security protocols, experts agree WPA3 is best for Wi-Fi security. As the most up-to-date wireless encryption protocol, WPA3 is the most secure choice.
What is the difference between 802.11 ac and 802.11 ax?
How is 802.11ax different from 802.11ac? 802.11ac operates in the 5Ghz range only, while 802.11ax operates in both the 2.4Ghz and 5Ghz ranges, thus creating more available channels. … 802.11ax supports up to eight MU-MIMO transmissions at a time, up from four with 802.11ac.
What is difference between 802.11 n and 802.11 ac?
In fact 802.11ac uses the 5GHz band while 802.11n uses 5GHz and 2.4GHz. Higher bands are faster but lower bands travel further. … It is built into the 802.11ac specification and is ‘smart signal’ which detects where connected devices are and increases signal strength specifically in their direction.
What is the difference between 802.11 a 802.11 b 802.11 g and 802.11 n?
In basic terms, 802.11n is faster than 802.11g, which itself is faster than the earlier 802.11b. … Among its key innovations, 802.11n adds technology called multiple-input multiple-output (MIMO), a signal processing and smart antenna technique for transmitting multiple data streams through multiple antennas.
How wireless WPA2 can be hacked?
In the last 24 hours, the media has broadly covered the WiFi WPA2 security hack. A recently discovered vulnerability could allow attackers to intercept data being transmitted between a WiFi access point and a computer or mobile device, even if that data is encrypted.
