Appendix D Wireless LANs P-2612HW Series User’s Guide 519 4 The RADIUS server distributes the PMK to the AP . The AP th en set s up a key hierarchy and management system, usin g the PMK to dynamica lly generate unique data encryption k eys.

Appendix D Wireless LANs P-2612HW Series User’s Guide 520 4 The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create tempor al encryption keys. They use these keys to encrypt data exchanged between them. Figure 324 WP A(2)-PSK Authentication Security Parameters Summary Re fer t[...]

Appendix D Wireless LANs P-2612HW Series User’s Guide 521 Antenna Overview An antenna couples RF signals onto air . A tr ansmitter within a wireless device sends an RF signal to the antenna, whic h propagates the signal through the air . The antenna also operates in reverse by capturing RF signals from the air . P ositioning the antennas properly[...]

Appendix D Wireless LANs P-2612HW Series User’s Guide 522 • Omni-directional antennas send the RF sign al out in all directions on a horizontal plane. The cover age area is torus-sh aped (like a donut) which makes these antennas ideal for a room environment. With a wide cove rage area, it is possible to make circular ov erlapping cov erage area[...]

Appendix D Wireless LANs P-2612HW Series User’s Guide 528 In step 3, you add anot her access point ( AP2 ) to your network. AP2 is out of ran g e of AP1 , so you cannot use AP1 for the WPS handshake with the new access point. However , you know that Client 2 supports the registrar function, so you use it to perform the WPS handshak e instead. Fig[...]

Appendix D Wireless LANs P-2612HW Series User’s Guide 529 • When you use the PBC method, there is a short period (from the moment you press the button on one device to the moment you press the button on the other device) when any WPS-enabled devi ce could join the network. This is because the registrar has no wa y of id entifying the “corre c[...]
