What are the two main standards for WLAN?
There are currently four specifications in the family: 802.11, 802.11a, 802.11b, and 802.11g. All four use the Ethernet protocol and CSMA/CA (carrier sense multiple access with collision avoidance instead of CSMA/CD) for path sharing.
What are the wireless standards used in a WLAN?
Table 7.5. 802.11 Wireless Standards
|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 three wireless security standards?
WiFi routers support a variety of security protocols to secure wireless networks: WEP, WPA and WPA2. However WPA2 is recommended over its predecessor WPA (Wi-Fi Protected Access).
What are 802 wireless standards?
IEEE 802 wireless standards. IEEE 802 is a collection of networking standards that cover the physical and data-link layer specifications for technologies such as Ethernet and wireless. These specifications apply to local area networks (LAN) and metropolitan area networks (MAN).
How many IEEE 802.11 standards are there?
The IEEE working groups have developed over 1,100 standards, with over 600 standards under development. Out of those 1,100, over 40 are part of the 802.11 family.
What are the 3 types of Wi-Fi?
Wireless Network Standards
The five Wi-Fi technologies are A, B, G, N and AC. B and G use the 2.4 GHz frequency; A and AC use the 5 GHz frequency; and N uses both 2.4 and 5 GHz frequencies. Your choice for your home or business will come down to three: Wireless G, N or AC.
Which of the following 802.11 standards is best for wireless encryption security?
AES is a widely used standard and recommended for use. WEP is the least secure wireless encryption type, and WPA2 is the most secure wireless encryption type.
Does 802.11 b/g/n support 5g?
Generally, a router that states it’s 802.11a/g/n, or 802.11ac will work at 5GHz. However, a router that is 802.11b/g/n has a slim chance of supporting that frequency, and you may need to upgrade. If your router supports 5GHz connectivity, the next thing to do is to check your adapter.
What are the types of wireless security?
There are three types of wifi encryption protocols: Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), and Wi-Fi Protected Access Version 2 (WPA2). These encryptions have one thing in common — protecting the data on your network — but the main difference lies in how well they do so.
What are the five techniques used for wireless security?

What is the most effective wireless security?
Wi-Fi Protected Access (WPA), WPA2, and WPA3 encrypt information being transmitted between wireless routers and wireless devices. WPA3 is currently the strongest encryption.
What is Wi-Fi 802.11 b/g n?
The five Wi-Fi (802.11) technologies (a, b, g, n and ac) are often abbreviated BGN, ABGN and A/B/G/N/AC in the specifications for wireless routers, Wi-Fi access points and the Wi-Fi in portable devices. For example, “N” means 802.11n. Multiple Radio Chains (2×2, 4×2)
What is 802.11 b standard offering in terms of security?
To be able to secure a wireless network, the 802.11 standard includes a set of security features: Service Set Identifier (SSID) which is used to control access to an Access Point (AP), the Access Control List (ACL) to prevent unauthorized access, and the Wired Equivalent Privacy (WEP) protocol intended to provide data …
What is the latest wireless standard?
The newest version of WiFi standards is 802.11ax (WiFi-6) and is an upgrade over the previous standard, which is 802.11ac (WiFi-5). This upgraded standard, Wifi 6, is mainly for compatible devices (like routers) to transmit wifi signals more efficiently.
