Each SkyExtender DualBand has 32 MAC addresses assigned to it. The MAC
address of the SkyExtender’s 5 GHz radio (as seen from the SkyGateway™) is
printed on the label affixed to the base of the SkyExtender DualBand. The
MAC address for the access point is 1 less than the MAC address of the
SkyExtender’s 5 GHz radio.
The MAC addresses reserved for use by WLAN SSIDs (basic SSIDs, or BSSIDs)
begin with the MAC address on the label at the bottom of the SkyExtender
DualBand minus-31.
MAC addresses use a base-16 (hexadecimal) system in which the letters A–F
represent numbers 10–15. For example, if the MAC address of the
SkyExtender DualBand is 00 0A DB 01 31 9F, the reserved addresses start with
the MAC address 00 0A DB 01 31 80.
oSetup information for the access point:
oA (case-sensitive) wireless SSID for each virtual WLAN Wi-Fi network
oA unique IP address for the management of the access point if it’s not
connected to a DHCP server
oA default gateway and subnet mask for the management network if the
access point is not on the same subnet as your PC
NOTE Plan on configuring the SkyExtender DualBand before mounting it.
Some steps, such as those requiring a serial cable, are easier if the
access point is more accessible.

This chapter provides instructions for planning and performing the physical
installation of the SkyExtender DualBand.
Planning your installation
When choosing a site for the SkyExtender DualBand, consider the radio frequency
(RF) environment and the physical layout of the area.
Trees, buildings, and hills can impede a wireless signal. When assessing a site,
examine the overall topology of the wireless path for possible obstructions,
existing or planned. The radio environment is dynamic and can deteriorate over
time as structures appear or are relocated.
Plan on testing potential sites to determine the suitability of the link topology for
target applications. Interference on your desired frequency results in overlapping
signals, causing outages or intermittent drops in throughput.
Once you’ve identified a potential site, use a topographic map or path profile
software to ensure that terrain or obstacles will not interfere with the links.
The site survey process should be an ongoing one. To verify that a site is relatively
interference-free, make site audits every 6 to 12 months, scheduling regular
maintenance visits to coincide with the site audits.
Mounting and cabling
The section provides instructions for physically installing the SkyExtender
DualBand.

Installation Guide.
Make sure that you allow enough clearance for the 2.4 GHz antennas you’ll
attach to the bottom of the SkyExtender.
2Connect the 2.4 GHz antennas.
The access point requires attachment of the two 2.4 GHz antennas included
with the device. Screw the antennas onto the standard N connectors on the
underside of the SkyExtender DualBand.
Figure 1. Attaching the antennas

SkyPilot SkyExtender DualBand Installation and Setup Guide 13
3Connect the SkyExtender DualBand to the power supply.
Connect the Ethernet straight-through cable (provided) between the power
injector and the Ethernet port on the base of the SkyExtender DualBand.
Plug the AC adapter into the power injector.
Figure 2. Providing power to the SkyExtender DualBand
NOTE The external Ethernet port on the SkyExtender DualBand is limited to
providing power to the device; it cannot handle data traffic. Do not
attempt to connect the power injector to a network switch or other
device.
Powering on
When power is supplied to the SkyExtender DualBand, it starts a routine power-
on sequence that you can monitor by observing the pair of LED lights on the
underside of the device.
While the device is initializing and searching for a GPS signal, both LED lights
blink four times in a repeating cycle.

SkyPilot SkyExtender DualBand Installation and Setup Guide
14
When the Link LED turns steady green and the Activity LED is off, the SkyExtender
DualBand is initialized and listening for hello signals from other devices. When
both LEDs are steady, the SkyExtender DualBand is successfully connected to the
wireless network.
The sequence takes about 15 minutes while waiting to acquire a GPS signal. (The
SkyExtender DualBand must have access to a GPS signal to complete the
sequence.)

C o n f i g u r i n g S k y E x t e n d e r D u a l B a n d
After installing the SkyExtender DualBand, you need to provide both the
SkyExtender and access point components of the device with configuration
information that they need for network operations.
This chapter tells you how to use the SkyPilot EMS software to configure the
SkyExtender DualBand for both mesh networking and Wi-Fi operation.
Before you begin
Before starting configuration, make sure the SkyExtender DualBand is powered
on and capable of receiving a signal from a SkyGateway or SkyExtender.
Additionally, make sure the EMS software is installed (both on a central server and
a client) and set up for configuring SkyPilot devices.
After getting a configuration from the provisioning server, the SkyExtender
DualBand will establish a link to the SkyGateway (or to another SkyExtender) and
use DHCP to retrieve an IP address and instructions for downloading
configuration information stored on the server.
Detailed procedures for using EMS software are provided in the SkyPilot Network
Administration Guide available on the SkyPilot Network Software CD or the SkyPilot
website at www.skypilot.com.
Automatic configuration versus manual configuration
The SkyExtender and access point contained in the SkyExtender require network
configurations to operate on the wireless mesh network. SkyPilot gives you a

choice of two modes for provisioning devices with configurations: automatic or
manual.
Automatic provisioning requires the use of SkyPilot EMS software to create
configurations that an unattended central server can distribute to devices on the
wireless mesh network. Although automatic provisioning requires more setup
time than manual provisioning, it greatly simplifies the administration of a
growing network.
Usually performed in the field, manual provisioning permits the configuration of
only a single device at a time, creating the minimum settings required for a
wireless link and storing them in the device’s flash (nonvolatile) memory.
For more information on provisioning modes, see Getting Started with the SkyPilot
Network, provided on the SkyPilot Network Software CD.
Choosing a WLAN configuration
Before starting configuration, decide on the type of Wi-Fi network you want to
configure at the access point location.
Most WLAN deployments use one of two common types of WLAN configuration:
oAn open (unprotected) Wi-Fi network, which does not authenticate users or
which depends on authentication by a backend system such as a captive
portal
oA Wi-Fi protected access (WPA) network, which uses standards-based client
authentication and encryption
NOTE A WPA network requires a Radius server for authenticating users;
see the next section for information on setting up the server.
As you follow the steps for configuring the SkyExtender DualBand, the
procedures will direct you to the appropriate section depending on your type of
configuration.

SkyPilot SkyExtender DualBand Installation and Setup Guide 17
Setting up a Radius server for authenticating users
If you plan configure your SkyExtender DualBand access point for WPA, you must
first configure a Radius server with the following:
oThe IP address and shared secret of the SkyExtender DualBand access point.
oEAP-PEAP/MSCHAPv2 and EAP-TTLS/PAP or MSCHAPv2 (not EAP-TLS) suitable
for WPA. Your Radius supplier can provide instructions.
oA Users database with user names and passwords. You may also need to
identify a proxy Radius if you’re delegating some domains to other service
providers.
Preparing software images
The next steps for automatic configuration of the SkyExtender DualBand start
with preparing the software images, as described in this section, and continue
with the procedures described in the remaining sections of this chapter. For
information related to manual configuration, turn to Chapter 5, “Using the Access
Point Configuration Tool.”
Before you use the EMS software to set up automatic configuration of the
SkyExtender DualBand, make sure the most current software images are available
to the EMS client software. (You can identify software images by the prefixes and
version numbers in their names—for example, SkyGate.2.0.14.bin,
SkyConn.2.0.14.bin, SkyExt.2.0.14.bin, and SkyExtDB.2.0.14.bin.)
To provide the EMS software with access to the software images, copy the
images to the directory /var/ftp/pub/images/ on the provisioning server.
Starting the EMS client
After confirming that the current software images are in the appropriate
directory, you can run the EMS client software and start setting up automatic
configuration of the SkyExtender DualBand.
You‘ll run the EMS client software from a computer on the wireless mesh network
and use SkyProvision™ to set up a node profile for the SkyExtender DualBand.
