Term

Definition

 

to the Internet. EAP can support multiple authentication mechanisms, such as

 

token cards, smart cards, certificates, one-time passwords, and public key

 

encryption authentication.

 

 

fixed wireless

Wireless devices or systems in fixed locations such as homes and offices. Fixed

 

wireless devices usually derive their electrical power from the utility mains, unlike

 

mobile wireless or portable wireless which tend to be battery-powered. Although

 

mobile and portable systems can be used in fixed locations, efficiency and

 

bandwidth are compromised compared with fixed systems.

 

 

frequency allocation

Use of radio frequency spectrum regulated by governments.

 

 

frequency spectrum

Part of the electromagnetic spectrum.

 

 

goodput

Goodput is the ratio of the total bytes transmitted or received in the network to the

 

total air time required for transmitting or receiving the bytes. The air time includes

 

the retransmission time taken for both successful and dropped frames.Suppose

 

1000 frames of 1500 bytes each are transmitted in the network as follows:

 

50% of frames are transmitted successfully at MCS index 11 at 108 Mbps.

 

25% of the frames were dropped in the 1st attempt at 108 Mbps but were

 

successfully transmitted using MCS index 3 at 54 Mbps in the second attempt.

 

The remaining 25% are dropped in both the attempts.

 

Then the effective rate is calculated as: The total bits transmitted / the total air

 

time. In this example: (500 * 1500 + 250 * 1500) * 8 / (total air time for 50% frames +

 

total air time for 25 % frames retransmitted + total air time for 25% dropped frames)

 

= 40.5 Mbps.

 

 

hot spot

A WLAN node that provides Internet connection and virtual private network (VPN)

 

access from a given location. A business traveller, for example, with a laptop

 

equipped for Wi-Fi can look up a local hot spot, contact it, and get connected

 

through its network to reach the Internet and their own company remotely with a

 

secure connection. Increasingly, public places, such as airports, hotels, and coffee

 

shops are providing free wireless access for customers.

 

 

hot zone

A wireless access area created by multiple hot spots located in close proximity to

 

each other. Hot zones usually combine public safety access points with public hot

 

spots. Each hot spot typically provides network access for distances between 100

 

and 300 feet; various technologies, such as mesh network topologies and fiber

 

optic backbones, are used in conjunction with the hot spots to create areas of

 

coverage.

 

 

Infrared Data Association(IrDA)

An industry-sponsored organization set up in 1993 to create international standards

 

for the hardware and software used in infrared communication links. In this

 

special form of radio transmission, a focused ray of light in the infrared frequency

 

spectrum, measured in terahertz, or trillions of hertz (cycles per second), is

 

modulated with information and sent from a transmitter to a receiver over a

 

relatively short distance

 

 

IR wireless

The use of wireless technology in devices or systems that convey data through

 

infrared (IR) radiation. Infrared is electromagnetic energy at a wavelength or

 

wavelengths somewhat longer than those of red light. The shortest-wavelength IR

 

borders visible red in the electromagnetic radiation spectrum; the longest-

 

wavelength IR borders radio waves.

 

 

microwave

Electromagnetic energy having a frequency higher than 1 gigahertz (billions of

 

cycles per second), corresponding to wavelength shorter than 30 centimeters.

 

Microwave signals propagate in straight lines and are affected very little by the
