Configuration
Enable 2X Mode
The Skyline Access Point supports 2X
provide data rates of up to 108 Mbps, twice the speed of standard 802.11a devices. By
default, 2X mode is disabled.
When 2X mode is disabled, the Skyline Access Point complies with the IEEE 802.11a
standard, can operate on one of eight Channels, and can achieve speeds of up to
54 Mbps.
When 2X mode is enabled, the Skyline Access Point does not comply with the IEEE
802.11a standard, can operate on one of three Channels, and can achieve speeds of
up to 108 Mbps.
Note:
Channel
802.11a devices spread a radio signal over a range of frequencies. The IEEE 802.11a
specification allocates the available frequencies in the 5 GHz band into a series of
operating Channels that are identified by a Channel number and a center carrier
frequency. 802.11a devices on the network that are configured for Infrastructure mode
will receive a Channel assignment from the Access Point.
The number of available Channels varies by country. In the United States, a Skyline
802.11a device can use eight Channels in 802.11a-compliant mode: Channel 36 (5.18
GHz), Channel 40 (5.20 GHz), Channel 44 (5.22 GHz), Channel 48 (5.24 GHz), Channel
52 (5.26 GHz), Channel 56 (5.28 GHz), Channel 60 (5.30 GHz), and Channel 64 (5.32
GHz). In the United States, a Skyline 802.11a device can use three Channels in 2X
mode: Channel 42 (5.21 GHz), Channel 50 (5.25 GHz), and Channel 58 (5.29 GHz).
Keep in mind that each Channel in 2X mode overlaps multiple Channels in 802.11a
mode.
Note:
SSID
The SSID (Service Set ID), which is also referred to as the ESSID (Extended Service Set
ID), is a text string that all members of the same 802.11a network share.
The SSID may be up to 32 alphanumeric characters long, including spaces. In an
Infrastructure network, the SSID must match on all Skyline 802.11a Access Points and
802.11a clients (unless a client's SSID is "any"). Devices that do not share the same
SSID cannot communicate.
Send Rate
The IEEE 802.11a specification supports eight data rates: 54 Mbps, 48 Mbps,
36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps, 9 Mbps, and 6 Mbps. Skyline's 2X mode
supports eight data rates: 108 Mbps, 96 Mbps, 72 Mbps, 48 Mbps, 36 Mbps,
You must configure all devices in the same network to use 2X mode. A device
in 2X mode cannot communicate with a device in 802.11a mode.

regulatory information concerning Channel selection.
