While some of the standards are stable and are usable in multiple environments, it is not the same with equipments that comply to a different standard. The report also presents advantages - disadvantages map between the standards that are existing and the reason why there is so many. We have also listed the security issues that plague the usage of WLANs.
Most of the Wireless LAN devices work under IEEE (Institution of Electrical and Electronics Engineers) standards. All the standardization started with 802.11 standards released by IEEE. Wireless LAN uses the radio waves for transmitting data from one to the other. It uses different frequencies for transmitting and receiving. The 802.11 laid down the rules for the communication protocol and specified which of the layers in OSI (Open System Interconnection model)23 are modifiable in case of WLAN. This paved way for changes in specific layers in OSI namely, the physical and the data link layers.
In the initial stages of the development, the WLAN supported transmission at 2 MBPS (Mega Bits Per Sec) speed levels. When devices were built under this standard, they could maximum reach only these speeds. However new standards were introduced which goes up to 5.5 MBPS and 11 MBPS, in lieu of the original 1 and 2 MBPS that was achieved earlier. By 1999, it was amended and was expected to support 54 MBPS maximum and they were working at a clock rate of 5GHz. While the first set of standards was called only 802.11, the later ones came to be known as 802.11b and 802.11a. While 'a' is able to operate at a higher frequency, namely, 5 GHz (Giga Hertz), it is able to run it a higher speed than that of 'b'.
WLAN implementations come up in multiple modes of operation. The equipments could be operating on a peer-to-peer mode or ad hoc mode. In this mode, the devices, could be PCs, communicate between them after recognizing each others presence. This is comfortable where one mobile unit has to communicate to another mobile unit over a WLAN. It is single, one-to-one and reasonably fast. No other needs be met under this methodology of operation. The second mode of operation is the common one, that through the Wireless Access Point. These access points connect multiple devices over the wireless network to a networked Ethernet connectivity. On one side the Access Point is a wireless switch and on the other it is Ethernet connectivity. This will help in connecting up like router or a switch multiple terminals to the Ethernet port. Access Points offer more than one technologies.
Wi-Fi or Wireless Fidelity is one of the most commonly used wireless system in vogue. WiFi is a system that works with RF frequencies going up to 5.2Ghz. This means that we can have distances of up to 2 kilometers covered ...Download file to see next pagesRead More

Security in Wireless LAN

...Setting up a new wireless network Before venturing onto the security aspect it will be worthwhile here to have a glimpse of setting up a reliable andefficient network. The primary objective of setting up a WLAN is to increase the mobility and broaden the scope of work-area. Non-existence of wiring blues also tilts the balance in favor of WLAN. Basic building blocks of WLAN networks are; Access point: It is basically a transmitter having an antenna on one side and connecting wires on the other side attached to the Ethernet, DSL cable, modem etc. Linksys WAP 11, Apple AirPort, Cisco Aironet 350 Series etc. are some of the well known access points. Antenna: It determines the reach of the WLAN. It is basically a transceiver i.e. receiving...

... and 1 to 2 miles for outdoor. The main advantage of UHF is its range. The disadvantage of these technologies (UHF) is its low throughput. RF license are required for protected bands that are provided by radio authorities in each country who regulate and license specific frequencies to users. (Guide to Wireless LAN Technologies) The most commonly used Wireless technology is spread spectrum that can provide a data rate up to 20 Mbps. Because the Federal Communication Commission (FCC) does not require site licensing for the bands used by spread spectrum systems, therefore, this technology has become the standard for high-speed RF data transmission. Two types of modulation schemes are commonly used to encode spread spectrum signals; direct...

Dental Veneers as a Breakthrough in Modern Dental Technology

In today’s fashion-conscious world, porcelain and composite veneers remain some of the most popular choices for people seeking to improve the esthetics of their teeth. Porcelain veneers have several advantages when compared to composite veneers including durability, resistance to staining, and amount of tooth structure removed during the procedure.
First and foremost, the porcelain veneers are very durable. They are also very thin – usually between 0.5 - 0.7 millimeters – and brittle, although once bonded to a healthy tooth structure they can become quite strong. The bonding process increases durability and veneers made of porcelain can last for many years, oftentimes between 10-15 years depending on how wel...

Organisations in the Engineering and Technology Environment: Singapore Airlines

In those days, just three flights per week, to Kuala Lumpur, Ipoh, and Penang, were all that the people in Singapore were privileged to. There were very fast developments in the situation in a span of two decades. During this period, Singapore’s Kallang Airport gained international exposure and started making huge additions to its fleet. Soon after the birth of the Federation of Malaysia on February 1963, the Malayan Airlines came to be known as the Malaysian Airlines, and in 1966, it was renamed the Malaysian-Singapore Airlines. But, in 1972, fifteen years from the day it was founded, Singapore Airlines split up with Malaysian Airlines and acquired a separate identity.
