LABEL DESCRIPTION
Channel Selection Set the operating frequency/channel depending on your particular region.
Select a channel from the drop-down list box. The options vary depending on the
frequency band and the country you are in.
Refer to the Connection Wizard chapter for more information on channels. This option is
only available if Auto Channel Selection is disabled.
Auto Channel Select this check box for the EMG2926-Q10A to automatically choose the channel with
Selection the least interference. Deselect this check box if you wish to manually select the channel
using the Channel Selection field.
Operating This displays the channel the EMG2926-Q10A is currently using.
Channel
Channel Width Select the wireless channel width used by EMG2926-Q10A.
A standard 20 MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps
(5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to
300Mbps (2.4GHz) or 450Mbps (5GHZ). An IEEE 802.11ac-specific 80MHz channel offers
speeds of up to 1.3Gbps.
Because not all devices support 40 MHz and/or 80 MHz channels, select Auto 20/40
MHz or Auto 20/40/80 MHz to allow the EMG2926-Q10A to adjust the channel
bandwidth automatically.
40 MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. A 80 MHz channel consists of two adjacent 40 MHz channels. The wireless
clients must also support 40 MHz or 80 MHz. It is often better to use the 20 MHz setting
in a location where the environment hinders the wireless signal.
Select 20 MHz if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.
802.11 Mode If you are in the Wireless LAN 2.4G > General screen, you can select from the
following:
• 802.11b: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to
associate with the EMG2926-Q10A. In this mode, all wireless devices can only
transmit at the data rates supported by IEEE 802.11b.
• 802.11g: allows IEEE 802.11g compliant WLAN devices to associate with the Device.
IEEE 802.11b compliant WLAN devices can associate with the EMG2926-Q10A only
when they use the short preamble type.
• 802.11bg: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to
associate with the EMG2926-Q10A. The EMG2926-Q10A adjusts the transmission rate
automatically according to the wireless standard supported by the wireless devices.
• 802.11n: allows IEEE 802.11n compliant WLAN devices to associate with the
EMG2926-Q10A. This can increase transmission rates, although IEEE 802.11b or IEEE
802.11g clients will not be able to connect to the EMG2926-Q10A.
• 802.11gn: allows either IEEE 802.11g or IEEE 802.11n compliant WLAN devices to
associate with the EMG2926-Q10A. The transmission rate of your EMG2926-Q10A
might be reduced.
• 802.11 bgn: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN
devices to associate with the EMG2926-Q10A. The transmission rate of your
EMG2926-Q10A might be reduced.
If you are in the Wireless LAN 5G > General screen, you can select from the following:
• 802.11a: allows only IEEE 802.11a compliant WLAN devices to associate with the
EMG2926-Q10A.
• 802.11a/an: allows both IEEE802.11n and IEEE802.11a compliant WLAN devices to
associate with the EMG2926-Q10A. The transmission rate of your EMG2926-Q10A
might be reduced.
• 802.11a/an/ac: allows both IEEE802.11a, IEEE802.11n and IEEE802.11ac
compliant WLAN devices to associate with the EMG2926-Q10A. The transmission rate
of your EMG2926-Q10A might be reduced.
