Basic Wireless Network standards

[Aandaleeb]

I am studying on a wireless networking. What are the basic wireless network standard which is used to access other networks. Like the 802.11 types. What are the different type of it and what speed did they offers. Are different types of standard compatible to each other. If yes then post some examples.

The standards of wireless networking were recognized by the IEEE (Institution of Electrical and Electronic Engineers) and are generally called the 802.11x standards, as there are currently three different ones in use: 802.11a, 802.11b, 802.11g.3 The dissimilarity are classify by how fast data can be transmitted between devices, how far they can be apart, what radio regularity they use and whether they will work with the other standards.

The different types of standards are 802.11a offers speed up to 54 mbps with a frequency of 5 GHz. It is compatible to 802.11a standard only. The other one is 802.11b that offers you a speed of 11mps with a frequency of 2.4 and 802.11g which is similar like the first one but it is compatible to 802.11g and 802.11b both.

For the basic wireless network standards from the above , you might ask why someone would desire to use the 802.11a, as 802.11g would appear to be superior in both range and compatibility. The answer is that the regularity used by 802.11a makes it less vulnerable to RF interference (electrical noise from motors or other electrical devices) than the other standards.

It is better for a manufacturing environment such as a factory. Also, the way that 802.11a wireless devices predetermine the signal is better for multimedia voice, video and large-image applications in compactly settled user environments. The prospect of 802.11b is less certain as it offers less than the a or g standard, so it is likely to be retained for backwards compatibility in networks where existing b standard components are in use. There is also a standard called WI-FI. This is not an electrical standard.

IEEE 802.11x standards explained above; it is a standard approved by a number of manufacturers to guarantee conformity between their wireless systems. To obtain WI-FI Certification, manufacturers must submit a sample product for testing to see if it will work appropriately with other WI-FI compliant devices. If the sample product passes the test, then the product can be certified for use with other WI-FI devices and can be sold with this certification.
