IEEE Std Amendment 5: Amendment 6: This amendment defines security mechanisms for IEEE This amendment introduces the concept of a security association into IEEE Finally, it specifies how IEEE An Interpretation is available at http: This amendment defines the medium access control MAC procedures to support local area network LAN applications with quality of service QoS requirements.
The procedures include the transport of voice, audio, and video over IEEE It also incorporates Amendments 1 through 8 including a corrigendum. Visit http: Amendment 9: Interworking with External Networks.
This amendment specifies enhancements to the IEEE It enables higher layer functionalities to provide overall end-to-end solutions. The main goals of this amendment are aiding network discovery and selection, enabling information transfer from external networks, enabling emergency services, and interfacing subscription service provider networks SSPNs to IEEE Part Protected Management Frames. This amendment defines enhancements to the IEEE Enhancements for Higher Throughput.

These systems may have an array To correlate the Xij elements of the matrix of multiple antennas only at one end of the X, the following method can be used communication link e. In MIMO a matrix of independent zero mean, unit vari- ance, complex Gaussian random variables, and 4 where are the complex correlation co- efficients between i-th and j-th transmitting antennas, and are the complex correlation coefficients between i-th and j-th receiving an- tennas.
The complex correlation coefficient values calculation for each tap is based on the power angular spectrum PAS with angular spread AS being the second moment of PAS.
Using the PAS shape, AS, mean angle-of-ar- rival AoA , and individual tap powers, a correlation matrices of each tap can be deter- mined.
Multiple antenna tech- nologies are being considered as a viable solu- tion for the next generation of millimeter-wave WLAN -.
