overlapping SonicPoints. However, it can slow down performance. Auto is probably the best
setting, as it will engage only in the case of overlapping SonicPoints.
Step 11 Protection Rate: The protection rate determines the data rate when protection is on. The
slowest rate offers the greatest degree of protection but the slowest data transmission rate.
Choose 1 Mbps, 2 Mbps, 5 Mbps, or 11 Mbps.
Step 12 Protection Type: Select the type of handshake used to establish a wireless connection: CTS-
only or RTS-CTS. 802.11b traffic is only compatible with CTS.
Step 13 CCK OFDM Power Delta: This setting determines the difference in transmission power
between 802.11b (CCK mode) and 802.11g (OFDM mode). When both 802.11g and 802.11b
are used simultaneously, 802.11g covers a smaller physical area than 802.11b. Increasing the
CCK OFDM Power Delta lowers the transmission power for 802.11b, so the two radio modes
will cover the same area. Choose 0 dBm, 1 dBm, or 2 dBm.
