Introduction to Wireless LAN 802.11
A wireless LAN (WLAN) is a network that uses radio waves to connect devices together. A WLAN can be used to connect computers to each other, to the Internet, and to wired networks (which use Ethernet cables).
WLANs are convenient because they allow users to move around freely within a building without having to connect and disconnect their computers from wires.
The technology that enables WLANs is called 802.11, which is a set of standards created by the Institute of Electrical and Electronics Engineers (IEEE). The most current version of 802.11 is 802.11ac, which was released in 2013.
802.11ac is the latest and most powerful WiFi standard. It offers speeds up to three times faster than 802.11n, allowing you to take full advantage of your broadband connection. If you have an older router, it’s time for an upgrade!
The Different Types of 802.11 Standards
There are three different types of 802.11 standards: 802.11a, 802.11b, and 802.11g. Each one has its own benefits and drawbacks, so it’s important to know which one is right for you before making a purchase.
802.11a
802.11a was the first of the three standards to be released. It operates on the 5GHz frequency band and can theoretically achieve speeds of up to 54Mbps. In practice, however, speeds are usually closer to 20-30Mbps. One of the main advantages of 802.11a is that it is less likely to experience interference from other devices because it uses a different frequency than most other wireless devices (e.g., Bluetooth).
However, one downside is that 802.11a has a shorter range than the other two standards – typically only about 30-50 feet indoors and 150 feet outdoors (without obstacles).
802.11b
802.11b was released shortly after 802.11a and operates on the 2.4GHz frequency band (the same as most other wireless devices). It has a maximum theoretical speed of 11Mbps but, in practice, speeds are usually closer to 5-6Mbps. One advantage of using 802.11b is that it has a much better range than 802.11a – up to 150 feet indoors and 300 feet outdoors (without obstacles).
However, because it uses the same frequency as many other wireless devices (e.g., Bluetooth), it is more prone to interference from other devices.
802.11g
802.11g was the last of the three standards to be released and is a combination of 802.11a and 802.11b – using both the 5GHz and 2.4GHz frequency bands. It has a maximum theoretical speed of 54 Mbps, but in practice, speeds are usually closer to 20 Mbps or 30 Mbps (just like 802.11a). One advantage of using 802.11g is that it has a much better range than 802.11a (up to 150 feet indoors and 300 feet outdoors without obstacles).
Furthermore, it’s less likely to experience interference from other wireless devices because it uses two different frequencies – although it can still be affected by other devices operating on either frequency band (e.g., Bluetooth).
In general, the best 802.11 standards for you will depend on your needs. 802.11a is great for users who need fast speeds and don’t mind having a shorter range. On the other hand, 802.11b and g are better for users who need a longer range or are more likely to experience interference from other devices.
Regardless of which standard you choose, all 802.11 standards are compatible with each other – so you can upgrade to a different one without having to replace your existing equipment.
Advantages and disadvantages of Wireless LAN 802.11
Wireless LAN 802.11 is a popular wireless networking standard that offers several advantages over other wireless networking technologies. Perhaps the most significant advantage of Wireless LAN 802.11 is its high data transfer rate, which allows for much faster data communication than other wireless standards.
Additionally, Wireless LAN 802.11 offers good security features and is compatible with a wide range of devices and operating systems. However, there are some disadvantages to using Wireless LAN 802.11 as well, such as its relatively short range and the fact that it can be susceptible to interference from other wireless devices.
Advantages:
- High data transfer rate
- Good security features
- Compatible with a wide range of devices and operating systems
Disadvantages:
- Relatively short range
- Susceptible to interference from other wireless devices
What is the future of Wireless LAN 802.11?
The future of Wireless LAN 802.11 is looking very bright. This technology has progressed significantly lately and indicates that things are not pulling back. 802.11ac is the latest and greatest standard, which offers speeds up to 7 Gbps. This is more than enough for most home users and even some small businesses.
What’s even more impressive is that the next generation of 802.11, 802.11ax, is already in the works. This new standard will offer even higher speeds, improved range, and better efficiency. It’s expected to be finalized in 2019 and should start appearing on devices soon after that.
So if you’re looking for a wireless networking solution that will be able to keep up with your needs for years to come,802.11 is a great option to consider.
Specification Comparison For technology 802.11
When it comes to Wireless technology, there are different standards that have been developed over the years. The most common ones are 802.11a, 802.11b, and 802.11g. Each of these has its own set of benefits and drawbacks that need to be considered before making a decision on which one to use.
802.11a:
Benefits: Higher data rates (up to 54Mbps), less interference from other devices using the same frequency range
Drawbacks: Not as widely compatible with older devices, shorter range than other standards
802.11b:
Benefits: More widely compatible with older devices, longer range than 802.11a
Drawbacks: Lower data rates (up to 11Mbps), more interference from other devices using the same frequency range
802.11g:
Benefits: Higher data rates (up to 54Mbps), more widely compatible with older devices than 802.11a
Drawbacks: More interference from other devices using the same frequency range, shorter range than 802.11b
