What are data rates and modulation? What does CCK or DQPSK or DBSK mean?
Data rates are frequency in which the data can be transmitted e.g. 11Mbps (Mega bits per second) when CCK is used. CCK stands for Complementary Code Keying. It is a code used to encrypt data for both 5.5 and 11Mbps data rates on wireless networks. It applies sophisticated mathematical formulas to the codes, allowing the codes to represent more information per transmission cycle, thus enabling up to 11Mbps of data rate. DQPSK stands for Differential Quadrature Phase Shift Keying. It is a digital modulation technique used in wireless networks. It can carry data upstream from computers to the Internet on a narrower frequency band which allows more upstream channels. DBSK is actually DBPSK and it stands for Differential Binary Phase Shift Keying. Like DQPSK, DBPSK is a modulation technique used by 802.11-compliant wireless LANs for transmission at 1Mbps. In layman’s terms, both WEP and TKIP are security protocols (controls) incorporated for Wireless networks as wireless network data are tr
