SkyExtender TriBand Installation and Setup | 1
Introduction
SkyExtender TriBand is a dual-radio solution that combines SkyPilot’s long-range,
high-capacity 5 GHz mesh backhaul with high-powered 2.4 GHz 802.11b/g and
4.9 GHz 802.11a access points that allow service providers and municipalities to
offer standard Wi-Fi services over great distances—for targeted hot zones or
dense, ubiquitous coverage patterns. With the ability to create multiple WLANS,
each with its own VLAN and security policy, the SkyExtender TriBand can support
several business models with a single service installation.

2 | Chapter 1 Introduction
TriBand Topologies
SkyExtender TriBand provides a unique opportunity for WISPs (wireless ISPs)
looking to combine scalable Wi-Fi capacity with the seamless coverage of a
wireless mesh network.
TriBand nodes on a wireless mesh network offer a basis for multi service networks
capable of providing end-to-end security and quality of service for a variety of
bandwidth-hungry applications and services, including VoIP and video
surveillance solutions.
The auto-discovery and rapid provisioning features of a SkyPilot wireless mesh
network can greatly reduce deployment and maintenance costs. Multiple
topology options and network scalability create intriguing options for rapidly
growing a metro Wi-Fi customer base.
Default Access Point Configuration
The SkyExtender TriBand access point is set up to provide Wi-Fi access right out of
the box. The access point includes a preconfigured WLAN with the SSID (Service
Set Identifier) SkyPilotTriBand, providing WPA-PSK (Wireless Protected
Access–Pre-Shared Key) protection. The first time that users attempt to connect to
the SkyPilotTriBand WLAN, they must provide a public password,
publicpublic.
You have the option of leaving the default configuration in place or creating a
new configuration for the access point.
NOTE A wireless network protected by WPA-PSK is vulnerable. To provide a
more secure level of protection, configure the WLAN for WPA
authentication, in which each user is authenticated separately.

Kit Contents
The SkyPilot SkyExtender TriBand kit includes:
The SkyPilot SkyExtender TriBand
One 2.4 GHz antenna
One 4.9 GHz antenna
A PoE (Power over Ethernet) adapter for powering the SkyExtender TriBand
Before You Begin
Before starting installation, you need the following:
A computer connected to the same network as the SkyExtender TriBand
(which by default is IP address 192.168.0.2).
A CAT-5 straight-through Ethernet cable for connecting the TriBand to a
power source.
Setup information for the access point:
A (case-sensitive) wireless SSID for each virtual WLAN Wi-Fi network.
A unique IP address for the management of the access point if it’s not
connected to a DHCP server.
A default gateway and subnet mask for the management network if the
access point is not on the same subnet as your PC.
MAC addresses for the TriBand and for the WLANs you set up for the
access point.
Each TriBand has 32 MAC addresses assigned to it. The MAC address of
the TriBand’s 5 Ghz radio (as seen from the SkyGateway™) is printed on
the label affixed to the bottom of the TriBand. The MAC address for the
access point is 1 less than the MAC address of the 5 GHz radio. The MAC
addresses reserved for use by WLAN BSSIDs begin with the MAC address
of the 5 GHz radio minus 31.
For example, if the MAC address of the TriBand is 000ADB01319F
(hexadecimal), the reserved addresses start at 000ADB013180 (the
difference being 1F hexadecimal, or 31 decimal).
Getting Help | 5
NOTE Plan to configure the SkyExtender TriBand before mounting it. Some
steps, such as those requiring a serial cable, are easier if the
SkyExtender TriBand is more accessible.

This chapter provides instructions for the physical installation of the SkyExtender
TriBand.
Chapter Highlights

8 | Chapter 3 Installing SkyExtender TriBand
Planning Your Installation
When choosing a site for the SkyExtender TriBand, 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—both
existing and planned. The RF environment is dynamic and can deteriorate over
time as structures appear or are relocated.
Plan to use test signals 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 ongoing. To verify that a site is interference-free,
make site audits every six to twelve months, scheduling regular maintenance visits
to coincide with the site audits.
Mounting and Cabling
The section provides instructions for physically installing the SkyExtender TriBand.
To install the SkyExtender TriBand:
1Mount the SkyExtender TriBand.
Follow the instructions provided in the SkyGateway/SkyExtender Installation
and Setup document.
Make sure that you allow enough clearance for the 2.4 GHz antennas you
attach to the bottom of the TriBand.
Mounting and Cabling | 9
2Connect the antennas.
The access point requires attachment of the antennas provided with the
device. Screw the antennas onto the standard N-connectors on the bottom of
the TriBand:
4.9 GHz antenna onto Ant1
2.4 GHz antenna onto Ant2
Figure 3-1. Attaching the antennas
3Connect the TriBand to the power supply.
As shown in Figure 3-2, connect the Ethernet straight-through cable
(provided) between the power injector and the Ethernet port on the bottom
of the TriBand.
Plug the AC adapter into the power injector.
10 | Chapter 3 Installing SkyExtender TriBand
Figure 3-2. Providing power to the SkyExtender TriBand
NOTE The Ethernet port on the TriBand is used to provide power and
Ethernet over a single CAT-5 cable. To use the Ethernet port, connect
a CAT-5 cable from the power injector port marked “Computer” to a
network switch or other device.
Powering Up
When power is supplied to the SkyExtender TriBand, it starts a routine power-up
sequence which you can monitor by observing the pair of LED lights on the
bottom of the device.
While the device is initializing and searching for a GPS signal, both LED lights blink
four times in a repeating cycle. (The SkyExtender TriBand must have access to a
GPS signal to complete its power-up sequence.)
When the Link LED turns steady green and the Activity LED is off, the TriBand is
initialized and listening for hello signals from other devices.
Powering Up | 11
When both LEDs are steady, the TriBand is successfully connected to the wireless
network.
The sequence takes about 15 minutes to complete (while waiting to acquire a GPS
signal).
NOTE Depending on your SkyPilot network configuration, the SkyExtender
TriBand may be unable to connect to the network until the device has
been configured as described in Chapter 4, “Configuring a SkyExtender
TriBand.”

SkyExtender TriBand Installation and Setup | 13
Configuring a SkyExtender TriBand
After installing the SkyExtender TriBand™, you need to provide the device’s
SkyExtender and access point components with the configuration information
they need for network operations.
This chapter explains how to use SkyPilot EMS software to configure the TriBand
for both mesh networking and Wi-Fi operation.

14 | Chapter 4 Configuring a SkyExtender TriBand
Before You Begin
Before starting configuration, make sure the SkyExtender TriBand is powered up
and capable of receiving a signal from a SkyGateway or SkyExtender.
Additionally, make sure the EMS software is installed (on both a central server and
a client) and set up for configuring SkyPilot devices. Detailed procedures for using
EMS software are provided in SkyPilot Network Administration, available from the
SkyPilot website at www.skypilot.com/support/.
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 configurations:
Open—Allows anyone with Wi-Fi capability to connect to the wireless
network via the SkyExtender TriBand access point. An open WLAN does not
authenticate users at the network layer, nor does it depend on authentication
by a backend system.
An open configuration raises obvious security concerns. The lack of
encryption other than SSL/TLS (which is available only during login) makes
the network vulnerable to unauthorized access and malicious actions
(including denial-of-service attacks).
You can provide backend authentication at the application layer through a
captive portal mechanism operating outside your wireless mesh network. A
captive portal forces all HTTP traffic from an unauthenticated user to a login
Web page and blocks the traffic until the user successfully logs in. (For more
information about captive portal mechanisms, refer to the following Web
page: http://en.wikipedia.org/wiki/Captive_portal.)
An additional disadvantage of open configurations is that users must begin
each session from a Web browser before they can use other Internet
applications, such as email, ssh, ftp, and chat clients.
Choosing a WLAN Configuration | 15
Protected—A Wi-Fi Protected Access (WPA) network which uses standards-
based client authentication and encryption. Users are authenticated via a
Radius server (which you’ll need to implement using a third-party solution).
WPA uses the IEEE 802.11b/g and IETF EAP protocols to give users a secure
connection with both the access point and the Radius server, allowing the
exchange of credentials (username@domain and password) and keys for
encrypting all traffic between the client and the access point—even after
authentication.
WPA encryption is by WEP, with the addition of keys that are unique to each
session and client. This additional keying mechanism eliminates the security
problems of the original WEP. You can use AES encryption with the TriBand for
even stronger encryption capabilities.
For more information about WPA, refer to the following Web page:
http://en.wikipedia.org/wiki/Wi-Fi_Protected_Access.
As you follow the procedure for configuring the TriBand, it will refer you to the
appropriate steps depending on the WLAN configuration you’ve chosen.
Setting Up a Radius Server for Authenticating
Users
If you plan to configure your SkyExtender TriBand access point for WPA, you must
first configure a Radius server with the following:
The IP address and shared secret of the TriBand access point.
EAP-PEAP/MSCHAPv2 and EAP-TTLS/PAP or MSCHAPv2 (not EAP-TLS) suitable
for WPA. (Your Radius supplier can provide instructions.)
A 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.)
16 | Chapter 4 Configuring a SkyExtender TriBand
Automatic vs. Manual Configuration
The SkyExtender and its contained access point require network configurations to
operate on the wireless mesh network. SkyPilot gives you a choice of two modes
for provisioning devices with configurations:
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.
After getting a configuration from the provisioning server, the SkyExtender
TriBand will establish a link to the SkyGateway (or to a SkyExtender or another
TriBand) and use DHCP to retrieve an IP address and instructions for
downloading configuration information stored on the server.
For automatic provisioning instructions, see “Automatic Provisioning
Procedure” on page 17.
Manual provisioning—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 memory.
For manual provisioning instructions, see “Manual Provisioning Procedure” on
page 21.
For more information on provisioning modes, see Getting Started with the SkyPilot
Network, available from the SkyPilot website at www.skypilot.com/support/.
Preparing Software Images | 17
Preparing Software Images
EMS Software
Before you use the SkyPilot EMS software to set up the automatic configuration of
the SkyExtender TriBand, make sure the most current software images are
available to the EMS program.
To provide the EMS program with access to software images, copy the images to
the folder /var/ftp/pub/images on the provisioning server.
Access Point Firmware
You can update the firmware in a SkyExtender TriBand access point either before
or after TriBand configuration. All you need is the IP address of the TriBand access
point and FTP installed on the host computer that contains the desired firmware
image. For detailed procedures, refer to “Updating Access Point Firmware” in
SkyPilot Network Administration.
Automatic Provisioning Procedure
Table 4-1 summarizes the steps required to configure a SkyExtender TriBand
device operating in automatic provisioning mode.
Table 4-1. Automatically Provisioning a SkyExtender TriBand (Page 1 of 4)

6Add the TriBand as a new node
on the wireless mesh network,
using the node profile you
identified or created in step 5.
When you add a node and
identify its type as SkyExtender
TriBand, an access point node is
automatically created (but not
assigned an access point profile),
and access point operations
become available on the EMS
client taskbar.

9If you’re configuring an open
access network, skip this step.
For protected access (WPA)
configurations, confirm that an
appropriate AP Radius profile
exists to provide the WAN with
information about the Radius
server that will be used to
authenticate users.
If no appropriate profile exists,
create one.
“AP Radius Profile Operations” in
SkyPilot Network Administration
NOTE The steps to configure a
Radius server vary
depending on the vendor
solution, and are outside
the scope of SkyPilot
documentation.
10 Confirm that an appropriate AP
WLAN SSID profile exists for the
desired network configurations
(protected or open). The profile
should be set up as follows:
If you’re setting up multiple
WLAN SSIDs with different
security policies and/or
multiple IP address spaces, the
use of VLANs is highly
recommended.
Broadcast SSID should be
enabled.
SSID Status should be active.
An appropriate security policy
should be set: WPA for
protected networks, None for
open networks.
If no appropriate profile exists,
create one.
“AP WLAN SSID Profile Operations”
in SkyPilot Network Administration
Table 4-1. Automatically Provisioning a SkyExtender TriBand (Page 3 of 4)
Step Refer to
20 | Chapter 4 Configuring a SkyExtender TriBand
11 Confirm that an appropriate
access point node profile exists.
(Remember that this profile is
separate from the one that’s
assigned to the TriBand node you
added in step 6.)
The profile’s attributes should
include the access point profiles
you created in the previous steps:
AP security, AP Radius (for
protected networks), and WLAN
SSID.
If no appropriate profile exists,
create one.

Manual Provisioning Procedure | 21
Manual Provisioning Procedure
To configure a TriBand that’s in manual provisioning mode, you first configure its
SkyExtender portion (following the same procedure as for SkyExtenders), and then
you configure its access point.
To manually provision a SkyExtender TriBand:
1Log in to the SkyExtender portion of the TriBand.
You can connect to a TriBand and access its command-line interface via a
terminal session from a console connected to the TriBand’s RJ-45 serial port.
After logging in (by supplying a password), you can enter commands at the
command prompt. For detailed cabling and access instructions for the
command-line interface, refer to the SkyPilot Command-Line Interface
Reference.
2Configure the SkyExtender by using the set prov batch command.
3Enter the set prov manual command so that the SkyExtender uses
manual provisioning mode when it next starts.
4Log in to the TriBand’s access point.
You can connect to an access point and access its Web-based interface via a
network connection to the SkyExtender portion of the TriBand or by a direct
Wi-Fi connection to the access point. After logging in (by supplying a
password), you can configure the access point through its Web-based
interface. For detailed network setting requirements and access instructions
for the Web-based interface, refer to the SkyPilot Web Interface Reference.
5Using the Access Point Configuration page, configure the access point’s
global configuration parameters.
6Using the WLANs Settings page, configure the SSIDs.
7Optionally, configure any additional access point settings that you want.

FCC Radio Frequency Interference Statement
SkyExtender TriBand FCC Number: RV7-DBE1010
This equipment has been tested and found to comply with the limits for a class B
digital device, pursuant to part 90 of the FCC Rules. These limits are designed to
provide reasonable protection against interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and if not
installed, and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try and correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the distance between the equipment and the receiver.
Connect the equipment to an outlet on a circuit different from that to which
the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This equipment has been certified to comply with the limits for a class B
computing device, pursuant to FCC Rules. In order to maintain compliance with
FCC regulations, shielded cables must be used with this equipment. Operation
with non-approved equipment or unshielded cables is likely to result in
interference to radio and TV reception. The user is cautioned that changes and
modifications made to the equipment without the approval of manufacturer
could void the user's authority to operate this equipment.

Maximum Permissible Exposure
In order to meet the FCC’s requirement of 1 mW/cm2 for Maximum Permissible Exposure
(MPE) at 4.9 GHz, the SkyGateway/SkyExtender units must be located a minimum of 36
cm (14 inches) from all persons. This distance is determined based upon the
aforementioned 1 mW/cm2 limit, measured data, and the following far-field peak power
density equation:
[]
S
dGP )20/)((
10282.0 +
=
where:
d = MPE distance in cm
P = Power in dBm (peak)
G = Antenna Gain in dBi
S = Power Density Limit in mW/cm2 (1 mW/cm2)
Certified laboratory measurements indicate that the FCC’s Power Density Limit of 1
mW/cm2 is met at a distance of much less than 36 cm (14 inches). However the
minimum distance for fixed or mobile transmitters is 36 cm even if calculations indicate
the MPE distance is much less.
FCC 15.203 statement
Because this device uses standard RF connectors for the external removable antennas,
professional installation is required.
IC RSS-210 statement
This device has been designed to operate with the antennas listed below. Antennas
having a gain greater than those on this list are strictly prohibited for use with this device.
The required antenna impedance is 50 ohms.
