4. Access Point
Short for Access Point, a hardware device or a computer's software that acts as a communication hub for users of a wireless device to connect to a wired LAN.
APs are important for providing heightened wireless security and for extending the physical range of service a wireless user has access to.

5. Infrastructure Mode
An networking framework in which devices communicate with each other by first going through an Access Point (AP).
In infrastructure mode, wireless devices can communicate with each other or can communicate with a wired network.
When one AP is connected to wired network and a set of wireless stations it is referred to as a Basic Service Set (BSS).

6. Infrastructure Mode
An Extended Service Set (ESS) is a set of two or more BSSs that form a single subnetwork.
Most corporate wireless LANs operate in infrastructure mode because they require access to the wired LAN in order to use services such as file servers or printers.

7. Ad-hoc Mode
An networking framework in which devices or stations communicate directly with each other, without the use of an access point (AP).
Ad-hoc mode is also referred to as peer-to-peer mode or an Independent Basic Service Set (IBSS).
Ad-hoc mode is useful for establishing a network where wireless infrastructure does not exist or where services are not required.

8. 802.11
refers to a family of specifications developed by the IEEE for wireless LAN technology.
specifies an over-the-air interface between a wireless client and a base station or between two wireless clients.
The IEEE accepted the specification in 1997.

9. Specifications in the 802.11 family – 802.11 e 802.11a
applies to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS).

22. IEEE 802.16a (Wi-MAX) Added support for the 2 to 11 GHz range. OFDM
DES3 and AES
Commonly referred to as WiMAX or less commonly as WirelessMAN or the Air Interface Standard,
IEEE is a specification for fixed broadband wireless metropolitan access networks (MANs).

23. Bluetooth Up to 2Mbps in the 2.45GHz band. FHSS. PPTP, SSL or VPN.
No native support for IP, so it does not support TCP/IP and wireless LAN applications well.
Not originally created to support wireless LANs. Best suited for connecting PDAs, cell phones and PCs in short intervals.

24. OFDM
Short for Orthogonal Frequency Division Multiplexing, an FDM modulation technique for transmitting large amounts of digital data over a radio wave.
OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver.
OFDM reduces the amount of crosstalk in signal transmissions a WLAN, and WiMAX technologies use OFDM.

25. FHSS
Acronym for frequency-hopping spread spectrum. FHSS is one of two types of spread spectrum radio, the other being direct-sequence spread spectrum.
FHSS is a transmission technology used in WLAN transmissions where the data signal is modulated with a narrowband carrier signal that "hops" in a random but predictable sequence from frequency to frequency as a function of time over a wide band of frequencies.

26. FHSS
The signal energy is spread in time domain rather than chopping each bit into small pieces in the frequency domain.
This technique reduces interference because a signal from a narrowband system will only affect the spread spectrum signal if both are transmitting at the same frequency at the same time.
If synchronized properly, a single logical channel is maintained.

27. FHSS
The transmission frequencies are determined by a spreading, or hopping, code.
The receiver must be set to the same hopping code and must listen to the incoming signal at the right time and correct frequency in order to properly receive the signal.
Current FCC regulations require manufacturers to use 75 or more frequencies per transmission channel with a maximum dwell time (the time spent at a particular frequency during any single hop) of 400 ms.

28. DSSS Acronym for direct-sequence spread spectrum.
DSSS is one of two types of spread spectrum radio, the other being frequency-hopping spread spectrum.
DSSS is a transmission technology used in WLAN transmissions where a data signal at the sending station is combined with a higher data rate bit sequence, or chipping code, that divides the user data according to a spreading ratio.
The chipping code is a redundant bit pattern for each bit that is transmitted, which increases the signal's resistance to interference.
If one or more bits in the pattern are damaged during transmission, the original data can be recovered due to the redundancy of the transmission.

29. CCK - Complementary Code Keying
Short for Complementary Code Keying, a set of 64 eight-bit code words used to encode data for 5.5 and 11Mbps data rates in the 2.4GHz band of b wireless networking.
The code words have unique mathematical properties that allow them to be correctly distinguished from one another by a receiver even in the presence of substantial noise and multipath interference.

30. CCK - Complementary Code Keying
CCK works only in conjunction with the DSSS technology that is specified in the original standard.
It does not work with FHSS.
CCK applies sophisticated mathematical formulas to the DSSS codes, permitting the codes to represent a greater volume of information per clock cycle.
The transmitter can then send multiple bits of information with each DSSS code, enough to make possible the 11Mbps of data rather than the 2Mbps in the original standard.

31. CSMA/CA
Short for Carrier Sense Multiple Access/Collision Avoidance, a network contention protocol that listens to a network in order to avoid collisions.
Unlike CSMA/CD that deals with network transmissions once collisions have been detected.

32. CSMA/CA
CSMA/CA contributes to network traffic because, before any real data is transmitted, it has to broadcast a signal onto the network in order to listen for collision scenarios and to tell other devices not to broadcast.
