NETGEAR Wireless-N Access Point WN802T v2 Reference Manual
Installation and Configuration 2-9
v1.0, September 2008
– If using multiple access points, it is better if adjacent access points use different
channels to reduce interference. NETGEAR recommends a channel spacing of 5
channels (for example, channels 1, 6, and 11). between adjacent access points.
– Wireless stations normally scan all channels, looking for an access point. If more than
one access point can be used, the one with the strongest signal is used. This can only
happen when the various access points are using the same SSID.
•MCS Index/Data Rate. From the pull-down menu, select the available transmit data rate
of the wireless network. Also, depending on the band selected, the set of rates will vary.
(When Auto Channel is enabled in the 802.11ng mode, then the default Channel Width
mode is 20MHz). The possible data rates supported are:
•Data Rates for Channel Width=20MHz and Guard Interval=short (400ms): Best,
7.2, 14.4, 21.7, 28.9, 43.3, 57.8, 65, 72.2, 14.44, 28.88, 43.33, 57.77, 86.66, 115.56,
130, & 144.44 Mbps
•Data Rates for Channel Width=20MHz and Guard Interval=long (800ms): Best,
6.5, 13, 19.5, 26, 39, 52, 58.5, 65, 13, 26, 39, 52, 78, 104, 117, & 130 Mbps
•Data Rates for Channel Width=40MHz and Guard Interval=short: Best, 15, 30,
45, 60, 90, 120, 135, 150, 30, 60, 90, 120, 180, 240, 270, & 300 Mbps
•Data Rates for Channel Width=40MHz and Guard Interval=long: Best, 13.5, 27,
40.5, 54, 81, 108, 121.5, 135, 27, 54, 81, 108, 162, 216 Mbps, 243, & 270 Mbps
The default is Best, which is the optimal setting.
•Channel Width. From the pull-down menu, select the desired channel width.
• 20 MHz - This is the static, legacy mode. It gives the least throughput.
• 40 MHz - This is the static, high-throughput mode.
• 20/40 MHz - This is the dynamic, compatibility mode. Legacy clients can operate at
20 MHz and 11n clients can operate at 40 MHz.
•Guard Interval. From the pull-down menu, select the desired guard interval. The guard
interval protects from interference from other transmissions. The default is Auto.
•Output Power. From the pull-down menu, select the transmit power of the access point.
The options are Full, Half, Quarter, Eighth, and Minimum. Decrease the transmit power if
two or more APs are close together and use the same channel frequency. The default is
Full. (The transmit power may vary depending on the local regulatory regulations).
