Installing a SkyAccess DualBand
This chapter provides instructions for planning and performing the
physical installation of a SkyAccess DualBand.
NOTE Professional Installation is required to ensure that the
proper antenna is employed such that FCC transmit
power limits for this equipment are not exceeded.
Planning the installation
In a typical wide area wireless mesh network, a SkyAccess DualBand
would be installed on a utility pole or the roof of a building. The effective
range of the SkyAccess DualBand is usually proportional to the height of
the installation.
When choosing a site for the device, consider the radio frequency (RF)
environment and physical characteristics of the site.
Trees, buildings, and hills can block a wireless signal. Also keep in mind
that the RF environment is dynamic and can deteriorate over time as
obstacles appear or are relocated.
Testing potential sites to determine the suitability of the link topology for
target applications is recommended. Once a potential site has been
identified, use a topographic map or path profile software to ensure that
terrain or obstacles will not interfere with the links.

The site survey should include an RF scan to identify available
frequencies. Check the preferred frequency at all locations; a frequency
that’s clear at one location may be crowded at another. Frequency
planning is a critical factor in planning and implementing a wireless mesh
network.
The site survey process should be ongoing. To verify that a site is
relatively free of interference, site audits should occur every 6 to 12
months, scheduling regular maintenance visits to coincide with the site
audits.
Cabling the SkyAccess DualBand
Ethernet cabling provides both power and data connectivity for the
SkyAccess DualBand.
The section provides instructions for attaching CAT5 cable to the device.
Terminate the appropriate grade and length of CAT5 cable with an
RJ-45 connector and plug it into the RJ-45 port on the back of the
SkyAccess DualBand.

Make sure the fit is snug so that the cable does not interfere with the
weather gasket.
Insert the weather gasket and secure the metal cover.
Press the CAT5 cable into the gasket and insert the gasket into the
housing, taking care not to twist or place unnecessary force on the
RJ-45 connector.
Fit the metal cover over the weather gasket and secure it with the
four machine screws supplied in the accessory kit.

Attach tie wraps to the neck of the weather gasket and tighten them
so that they slightly depress the neck.

The tie wraps provide relief from cable strain and ensure a fully
weatherproof seal.
Powering on the SkyAccess DualBand
Prior to mounting the SkyAccess DualBand, power on the unit to use the
onboard LEDs to facilitate optimal placement.
Connect the SkyAccess DualBand to the power supply, as follows:
a. Plug the AC adapter into an AC outlet.
b. Connect the Ethernet cable to the port labeled “CPE” on the
power injector.
c. Plug the AC adapter into the power injector.

Figure 6. Providing power to the SkyAccess DualBand
5 GHz
Check the LEDs on the SkyAccess DualBand.
If the connections are correct, the power LED (labeled “PWR”) and
the WAN activity LED (labeled “WAN Act”) on the SkyAccess
DualBand will illuminate. The WAN Act LED should blink and turn off,
but the PWR LED should remain lit.

Optimizing location
After powering on the SkyAccess DualBand, use the device’s LEDs to
identify the optimal location for mounting—a location where it can easily
acquire a signal from the wireless mesh network and quickly create links.
Confirm signal acquisition
ƒ
Position the SkyAccess DualBand near the intended mounting
location and watch the WAN Act LED for activity.
The LED starts to blink when it has acquired a signal from the
network and is attempting to set up a connection.
If the WAN Act LED does not start blinking within 30 seconds, try
changing the orientation of the SkyAccess DualBand or walk to a new
location; then repeat the process until the LED begins blinking.
When the LED starts blinking, make minor adjustments to find the
location where the signal is strongest. (The faster the LED blinks, the
stronger the signal.)
When the WAN Act LED blinks steadily and at a high rate, you have
an optimal signal. Go to the next section to verify the network
connection.
Verify network connection
ƒ
Watch the WAN Link LED for activity.
Within approximately 90 seconds of locating a signal, the WAN Link
LED should start to blink—first slowly, then more quickly.
When the WAN Link LED is solid and the WAN Act LED is blinking,
the SkyAccess DualBand has established an authorized connection
to the network, indicating that the current location is suitable for
mounting
If both the WAN Act LED and the WAN Link LED continuing blinking,
a signal is available but is not strong enough for reliable service.
Keep trying different locations until you can confirm a network
connection.

NOTE To optimize your SkyAccess DualBand installation, ask your
network administrator (at the Network Operations Center) to
measure signal strength on the node to which the SkyAccess
DualBand has established a link.
For more information on LED states, see Table 1.

Mounting the SkyAccess DualBand
After determining an optimal location the SkyAccess DualBand can then
be mounted in accordance with the procedure below.
Before mounting the device, disconnect the CAT5 cable from the power
injector to power down the device.
Connect the 2.4 GHz antenna.
To provide Wi-Fi connectivity, the SkyAccess DualBand requires
attachment of the 2.4 GHz antenna included with the device. Screw
the antenna onto the standard N connector on the back of the
SkyAccess DualBand.

Use the supplied clamps to secure the SkyAccess DualBand to the
pole; then loop the Ethernet cable around the mounting pole and
secure it with tie wraps.

Connecting to the wireless network
After mounting the SkyAccess DualBand, set up a connection to the
wireless network via a local computer or LAN. Once connected, a
subscriber can use the wireless network to gain access to Internet
services and applications.
Connection to the SkyAccess DualBand is accomplished with Ethernet,

Configuring the SkyAccess DualBand
A SkyAccess DualBand requires two different configurations: a network
configuration that allows it to operate on the wireless mesh network, and
an access point configuration that allows the device to support local
wireless connections via Wi-Fi.
For information about configuring both the device and the access point,
see the document “SkyPilot Network Administration”,
available in electronic format from the SkyPilot website at
www.skypilot.com/support/.

Accessing SkyAccess DualBand
Command-Line Interfaces
This appendix describes how to access the command-line interfaces that
SkyPilot SkyAccess DualBand provides for provisioning and
troubleshooting. You can connect to two different interfaces on the
SkyAccess DualBand: an interface with the device that operates as a
node on the wireless mesh network, and a separate interface with the
access point that extends Wi-Fi connectivity to subscribers.
Connect to the SkyAccess interface
You can connect to a SkyAccess DualBand and access the commandline interface through Telnet over an Ethernet connection. After logging in
(by supplying a password), you can enter commands at the command
prompt.
Mount and cable the SkyAccess DualBand according to the
instructions in Chapter 3.
Prepare a PC or laptop.
Open the network settings panel and assign the computer the IP
address 192.168.0.3 with a subnet mask of 255.255.255.0.
3 Connect the computer to the SkyAccess DualBand according to the
instructions in Chapter 3 (see on page 15).
Start a Telnet session.

Figure 11. Example Telnet login
After making an Ethernet connection to the SkyAccess DualBand, you
can manage and troubleshoot the device using a wide range of
commands available through the command-line interface. For detailed
descriptions of the commands, as well as sample output for many of
them, see SkyPilot Network Administration.
For comprehensive guidelines to troubleshooting devices on your
SkyPilot wireless mesh network, see Getting Started with the
SkyPilot Network.
Connect to the access point interface
You can connect to the access point command-line interface via Telnet
over a wireless network connection. (Typically, you will use this technique
to confirm the IP address of the access point component of the SkyPilot
DualBand.)
Prepare a PC or laptop.
You will need a Wi-Fi/WPA-PSK capable computer that’s within
operating range of the access point and a Telnet application you can
use to open a connection between the devices.
