- 1Active ScanningDuring an active scan, the client radio transmits a probe request and listens for a probe response from an AP.
- 2Passive ScanningWith a passive scan, the client radio listens on each channel for beacons sent by an AP.
- 3SDPService Discovery Protocol (SDP) provides the means for applications to discover the services provided by another Bluetooth device.
- 4RFCOMMSimple set of transport protocols, made on top of the L2CAP protocol, providing emulated serial ports
- 5TunnellingTunnelling is used to forward IP datagrams from a home address to a care-of address
- 65 characteristics of RF waves• Propagation
• Speed
• Wavelength
• Frequency
• Radio Communication - 7Bluetooth piconetA Bluetooth piconet connects up to 8 devices in active mode and up to 255 devices in parked mode
- 8Basic PiconetThis Bluetooth connection channel is used only when all 79 channels are used within the hop-set
- 9Adapted PiconetThis Bluetooth connection channel is used more widely and allows the system to use a reduced hop-set
- 10W-CDMAW-CDMA (Wide Code Division Multiple Access) is a 3G mobile wireless technology that promises much higher data speeds to mobile and portable wireless devices
- 11Frequency Division multiplexingFDM is a multiplexing technique that applies a different frequency to each of the signal streams being combined onto a single transmission medium
- 12Time Division multiplexingTDM technique assigns each communication stream to a different time slot in a time sequence and then transmits the time slots over a single transmission channel
- 13Basic Service Set (BSS)BSS is a RF transceiver of a wireless network adaptor can be configured. BSS provides point-to-point wireless bridging
- 14Independent Basic Service Set (IBSS)IBSS is a RF transceiver of a wireless network adaptor can be configured.
- 15HotspotIt is a public area where users can connect their device to a wireless access point.
- 16Spreading codeThe concept of CDMA is based around the fact that a data sequence is multiplied by a spreading code which increases the bandwidth of the signal.
- 17CSMA/CACSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) is a protocol for carrier transmission in 802.11 networks.
- 18CSMA/CDCSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the protocol for carrier transmission access in Ethernet networks.
- 19Mobile Ad hoc networks (MANETs)A mobile ad hoc network (MANET) is a continuously self-configuring, infrastructure-less network of mobile devices connected without wires.
- 20Smart Phone Ad hoc Networks (SPANs)SPANs leverage the existing hardware in commercially available smart phones to create peer-to-peer networks without relying on cellular carrier networks, wireless access points, or traditional network infrastructure
- 21ScatternetsA group of between two and ten non-synchronized piconets that connect through a common device that serves as a bridge between the piconets
- 22Hidden NodeThe hidden node problem occurs when a node is visible from a wireless access point (AP), but not from other nodes communicating with that AP. This leads to difficulties in media access control.
- 23RTS/CTSRTS/CTS is an additional method to implement virtual carrier sensing in Carrier sense multiple access with collision avoidance (CSMA/CA).
- 24AM (or Amplitude Modulation)In AM, a radio wave is modulated in amplitude by the signal that is to be transmitted. The frequency and phase remain the same.
- 25FM (or Frequency Modulation)
