Wireless Network Technologies


The use of laptops these days has further increased the demand for more wireless connections than was the case a few years ago. Wireless connection is easy to use provided there are the necessary hardware.
Types:
The most common wireless technologies available on the market are:
a. 802.11b Wireless Network Technology:
It is cheaper compared with other wireless network technologies available. It has the ability to work on speed up to 11Mbps and boasts of best signal range. The transmission speed of 802.11b wireless technology is the least of all wireless network technologies and is prone to interference by external sources because it operates at a frequency as low as 2.4GHz where this frequency range is unregulated. It is also not the best choice in terms of number of simultaneous users.
b. 802.11a Wireless Network Technology:
It is the highly priced. It boasts of higher transmission speed and has ability to accommodate more simultaneous users. Its performance is mostly impeded by obstacles in the line of sight. Its use in the frequency of up to 5GHz makes it to operate within a short range. However, it stands as a better choice in terms of signal interference as it operates above most of interfering gadgets such as microwaves. There is also a snag in system compatibility with 802.11b network adapters.
c. 802.11g Wireless Network Technology:
It is operates within 2.4 GHz frequency range and is susceptible to interferences. It is able to work up to same speed with 802.11a communication standard. The good thing about this technology is how it defies interference from outside sources and has also good signal range. It has speed up to 54Mbps.
