Zigbee Wireless Network Topology Network topology is fundamental to communication networks, dictating the arrangement and interconnection of links and nodes. In the context of Zigbee, there are three main types of network topology: point-to-point topology, multi-point topology and mesh topology. Each...
What is the purpose of the 802.11 wireless standard? 802.11 specifies the interface that enables over-the-air signaling between two or more wireless clients. It is the main bearer of communication for different electronic devices, including actuators, laptops, tablets and televisions. Each version of...
A New Scheme for Spreading & De-spreading in the Direct Sequence Spread Spectrum Mechanism The autocorrelation function of the DSSS sequence contains only one peak and the main peak of the DSSS sequence is wider than the peak of the BOC sequence. A Detection Algorithm for the BOC Signal Based...
Modulation Mode:Dsss; Channels:4, 8, 12 or 16; Type:Simultaneous Interpretation System; Video:Video; Communication:Wireless; Color:Silver; Category:Wireless Condenser Microphone; Frequency Response:20Hz-20kHz; WiFi Standard:IEEE Draft 2.0 802.11n; ...
Direct-sequence spread spectrum (DSSS) DSSS is a related technique to FHSS. It also spreads a transmitted signal across a wide channel, but it does so all at once instead of in discrete bursts separated by hops. It can achieve higher throughput, but DSSS systems are more susceptible to inte...

3. OSI Reference Model Considerations In some standards, the OSI reference model layers are pertinent to their specifications. Some considerations on the security at each of these layers is discussed below. • Physical layer (PHY) refers to the actual media such as wireless, cable, ...
• IEEE 802.11b : This wlan standard supports DSSS/CCK Physical layer. • IEEE 802.11g : This wlan standard supports both 11a and 11b and supports RF center frequencies of 2.4 GHz and 5 GHz. • IEEE 802.11n (WiFi 4) : This wlan supports OFDM and also MIMO is supported to enhance...
