What is the Wi-Fi standard?December 22, 2020
Wi-Fi standards define the speed and method of radio data transmission. Currently, the N (802.11n) standard with a speed of 150 to 600 Mbps is used. New AC technology (802.11ac) theoretically raises the speed to 1300 Mbps.
Other standards include BT 6265 (1.1 GHz) and 802.11ac-2 (4.1 GHz). Some networks, including those in Europe, Japan, Australia and the United States, use other standards that have different specifications.

What is the bandwidth?
Wireless networks use several standards to determine their network performance and bandwidth. Each standard has an upper limit to the amount of data that the network can transmit. The higher the data rate, the longer data can be carried. The most popular of these, 802.11a/b/g/n, supports up to 10Gbps in speed. Some networks, including some in Europe, use higher speeds, such as 802.11n or 2.4GHz, while most use 1Mbps.
Can a laptop use 802.11b/g/n?
Yes, but only if it includes an 802.11b/g/n adapter. 802.11b/g/n adapters require additional equipment to enable their operation. The most common are used in laptops to connect to high speed networks (Wi-Fi) and to use a computer as a wireless connection to the internet. Many people are concerned about the privacy and security of their data when they transfer information from a laptop to a network connection. Most people don’t install an 802.11a or b/g/n adapter.
What is the compatibility?
802.11b works with almost every laptop sold in the United States. It doesn’t work with some computers. However, other models are compatible. It’s important to check this page or the manufacturer’s website to determine if your computer will work with an 802.11n adapter or if it is already compatible. A laptop with an 802.11b/g/n adapter is the most compatible with 802.11n, but other models of computers will work better.
What is the speed?
802.11b supports up to 12Gbps in speed. Most laptops support up to 10Gbps, which is faster than 802.11a and 802.11b. However, it’s best to use an 802.11ac adapter.
How many ports do I need?
802.11n has four wireless ports. They are a 1.2 GHz, a 2.4 GHz, a 4.5 GHz and a 6 GHz. They can be used to connect other 802.11b/g/n devices that have a high speed connection. It is recommended that you have one port for each type of adapter you are buying. It is important to note that you need a port that matches all of the different wireless chips inside of your computer.
Does 802.11b work on older computers?
The newer computers with Intel integrated processor technology (integrated processors have faster speed than their older predecessors) may work better than some older computers (for example, the original PC computer in the mid-1990s could connect to high speed 802.11n networks). This is because there was a standardization process after it was released that gave Intel an advantage in this area.
Do all 802.11b/g/n adapters need to be purchased separately?
No, all 802.11b/g/n adapters that use the higher speeds will work on all computers sold in the United States. All 802.11b/g/n adapters also work with some laptops. But many newer laptops will only work with 802.11g/n or 802.11a. Some older laptops will work with only 802.11a. Many modern laptops, however, will not support all 802.11b/g/n standards. They may not use a 802.11b/g/n adapter.
