Solution Overview
SkyPilot Networks delivers a wireless, end-to-end broadband solution
that seamlessly supports high-capacity, high-coverage mesh networks.
Designed for managed-access networks and service providers, the
SkyPilot network takes broadband wireless the “last mile” with a costeffective, robust infrastructure solution.
Based on a high-performance architecture that deploys intelligent
antenna arrays, the SkyPilot network delivers a dynamic broadband
solution with significant advantages for business and home users.
SkyPilot wireless devices are simple to install and easily fit into any
type of wireless environment—metropolitan, business, or home.
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 expanding a metro Wi-Fi customer base.
SkyPilot devices’ multiple antenna configurations work within mixeduse environments of municipal applications and broadband Internet
access, supporting public-private partnerships such as public safety
services.
Mesh Network
The typical configuration for a SkyPilot network is a mesh topology,
which uses SkyExtenders to extend range and add network flexibility. In
a mesh configuration, subscribers can either connect directly to the
SkyGateway or connect indirectly via SkyExtenders (see Figure ). In
addition to adding range, a mesh network allows connections from
locations where obstructions prevent line-of-sight access to a
SkyGateway hub.
Mesh networks are ideal for dense subscriber environments, for filling
in coverage “holes,” and for reaching subscribers in areas where RF
communication is obstructed by hills, trees, buildings, or other
obstacles.

SkyGateway
The SkyGateway operates as a base station for a wireless mesh
network. It provides an interface between wired infrastructure and a
wireless network of subscribers who enjoy secure, high-speed access to
the Internet or to wide area networks.
A SkyPilot wireless network requires at least one SkyGateway for
operation. If necessary, you can add additional SkyGateways to increase
network capacity or provide redundancy.
The SkyGateway typically resides at a location with easy access to
wired infrastructure—usually a POP (point of presence) or data center.
For optimal performance, install the SkyGateway on an elevated site
such as a cell tower or the top of a tall building.
SkyExtender Devices
SkyExtenders, SkyExtender DualBands, and SkyExtender TriBands
provide a cost-effective way to add capacity and balance network loads
by operating as “repeaters” to extend the wireless range of a
SkyGateway (see Figure ). You can add any SkyExtender device to your
network to expand your coverage footprint and provide redundancy
through SkyPilot’s mesh networking features. SkyExtender devices
(except DualBands) can provide subscribers with a direct connection to
the wireless network via the device’s Ethernet port.
SkyExtender DualBand is a dual-radio solution that combines SkyPilot’s
long-range, high-capacity 5 GHz mesh backhaul with a high-powered
2.4 GHz 802.11b/g access point that allows service providers and
municipalities to offer standard Wi-Fi services over great distances—for
targeted hot zones or dense, ubiquitous coverage patterns.
SkyExtender TriBand integrates a 5.8 GHz mesh backhaul with the
DualBand’s access point and adds a third radio accessible through a
second access point. The second access point leverages the 4.9 GHz
Public Safety band, using 802.11a communication protocol. Each access
point uses a single antenna, and these
SkyPilot SkyAccess DualBand Installation
12
antennas have similar coverage patterns, providing a cost-effective
solution for municipal networks.
For optimal performance, install the SkyExtender in an elevated
location such as a roof, tower, or utility pole.
SkyConnector and SkyAccess DualBand
SkyConnectors link your subscribers to the SkyPilot wireless network. An
Ethernet port on the device allows a connection to a subscriber’s
computer, or to a local area network (LAN) via a data switch or router.
Designed for installation by the service provider, the SkyConnector
attaches to an external structure such as an eave, roof, or pole.
The SkyAccess DualBand offers the same features as a SkyConnector,
plus a Wi-Fi access point that enables service providers and
municipalities to provide standard 802.11 wireless access over great
distances, for targeted hot zones, or for dense coverage patterns.

Planning your Installation
When choosing a site for the SkyGateway or SkyExtender, consider the
radio frequency (RF) environment and the physical layout of the area.
Trees, buildings, and hills can attenuate or block a wireless signal.
When assessing a site, examine the overall topology of the wireless
path for possible obstructions—both existing and planned—as well as
seasonal changes of foliage and tree growth. 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.
Your site survey should include an RF scan to identify available
frequencies. You should also check your 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 network. (For device operating frequencies,
see Appendix C, “Specifications.”)
The site survey process should be ongoing. To verify that a site is
relatively free of interference, make site audits every six to twelve
months, scheduling regular maintenance visits to coincide with the site
audits.
For TriBand installations, operators should review laws and regulations
regarding the registration and use of the 4.9 GHz frequency in the area
of deployment. For example, 4.9 GHz is used in the US for public safety
information.
SkyPilot SkyAccess DualBand Installation
20
NOTE Plan to configure the SkyGateway or SkyExtender
before mounting it. Some steps, such as those
requiring serial console access, are easier if the
device is more accessible. For information about
configuration, see “Configuring the
SkyGateway/SkyExtender” on page 30.
SkyGateway Installation
In a typical wide area wireless mesh network, you’ll install a
SkyGateway on a tower or the roof of a tall building. The direct
coverage area of the SkyGateway is usually proportional to the height
of the installation.
You can also set up a SkyGateway for use in smaller-scale networks—for
example, a high-capacity business, an academic campus
interconnection, or a local access network. For smaller networks, you
can install the SkyGateway on the roof of a medium-height building or
on a utility pole.
SkyExtender Installation
You can install a SkyExtender in any location where a strong signal from
a SkyGateway (or another SkyExtender) is available: home rooftops, tall
buildings, or light and utility poles. Having fewer obstructions means
greater signal strength, a higher signal-to-noise ratio, and more
throughput.
GPS and the SkyGateway/SkyExtender
The SkyGateway or SkyExtender uses a GPS (Global Positioning System)
signal to synchronize itself with other devices on the network. The
strongest GPS signal is available outdoors, where the device has an
unobstructed view of the sky. (For indoor installations, such as for
configuration and testing, the optimal location is on a windowsill or
other opening with access to the sky.)
SkyPilot SkyAccess DualBand Installation
21
Upon startup, a SkyGateway or SkyExtender searches for a GPS signal,
and if the device can’t detect a signal, it will be unable to complete
startup and won’t establish wireless connections with other devices.
You can configure a SkyGateway or SkyExtender even if the device
can’t detect a GPS signal. While the device is searching for the GPS
signal, press the TILDE key (~) to bypass the search; the device will
then proceed through the startup sequence.
NOTE The GPS search should be bypassed only for device
configuration, not for standard operation. Without a GPS
signal, data will not be reliably transmitted between
devices.
The LEDs on the base of the device will confirm availability of a GPS
signal. For more information on the LEDs and GPS signal acquisition, see
“Monitoring the Power-On Sequence” on page 27.
Mounting
The first step of physically installing the SkyGateway or SkyExtender is
to mount the device as described below.
NOTE The figures in this section show the SkyGateway. For
SkyExtender, DualBand, and TriBand installations, your view
will differ slightly, allowing for antenna access through the
cable covers.
To mount the SkyGateway/SkyExtender:
Attach a magnetic level to the 1.25” to 2.0” diameter steel
mounting pole to verify that the pole is plumb (straight).
The figures in this section show the SkyGateway.
For SkyExtender, DualBand, and TriBand installations,
your view will differ slightly, allowing for antenna access
through the cable covers.
IMPORTANT

Cabling
Ethernet cabling provides power and data connectivity for the
SkyGateway or SkyExtender. Serial cabling provides connectivity for
troubleshooting and local configuration—connectivity that’s beneficial
and cost-effective for locations where access to the device is difficult,
such as cell towers. To cable the device for both Ethernet and serial

Figure 3-13. Providing power to the SkyGateway/SkyExtender
If you’re connecting a DualBand, skip this step. Likewise, if you’re
connecting a SkyExtender that will operate solely as a repeater on
the wireless mesh network, skip this step as a data connection is not
required.
Otherwise, connect the device to a WAN (for a SkyGateway) or a
PC/LAN (for a SkyExtender that’s also providing local access to the
wireless network).
NOTE DualBands don’t contain an Ethernet interface and can’t
detect any device connected to the power injector port
labeled “Computer”.
For a SkyGateway, connect a second Ethernet cable from the power
injector port labeled “Computer” to a router or data switch that
connects to the WAN or Internet (see Figure 3-14).

Monitoring the Power-On Sequence
When power is supplied to the SkyGateway or SkyExtender, it starts a
routine power-on sequence which you can monitor by observing the pair
of LED lights on the underside of the device.
The power-on sequence takes up to 15 minutes, depending on how
quickly the device can acquire a GPS signal.
NOTE The SkyGateway or SkyExtender must have access to a GPS
signal to complete its power-on sequence and start making wireless
network connections. And depending on your SkyPilot network
SkyPilot SkyAccess DualBand Installation
36
configuration, the device may be unable to connect to the network
until the device has been fully configured as described in “Configuring
the SkyGateway/SkyExtender” on page 30.

Configuring the SkyGateway/SkyExtender
To operate on the wireless mesh network, the SkyGateway or
SkyExtender requires a network configuration.
A SkyGateway will not transmit a wireless signal until it is configured,
and it will not be able to connect to other network devices without a
configuration.
SkyPilot offers two modes for provisioning devices with a configuration:
•
Automatic - 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.
Detailed procedures for using EMS software are provided in SkyPilot
Network Administration , available from the SkyPilot website at
www.skypilot.com/support/.
•
Manual - Usually performed in the field, manual provisioning
permits the configuration of 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. Manual provisioning is a
logical choice if you’re installing a test network or rolling out a
small-scale installation that isn’t expected to expand.
For more information about provisioning modes and procedures, refer
to Getting Started with the SkyPilot Network and SkyPilot Network
Administration, available from the SkyPilot website at
www.skypilot.com/support/.
SkyPilot SkyAccess DualBand Installation
40
Accessing the Command-Line Interface
SkyPilot devices include a command-line interface which you can use
for manual provisioning and troubleshooting.
You can connect to a device and access its command-line interface
through Telnet over an Ethernet connection or via a terminal session
from a console connected to the device’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.
Troubleshooting
After making an Ethernet or serial connection to the SkyConnector, you
can manage and troubleshoot the device using a wide range of
commands available through the command-line interface.
For detailed troubleshooting procedures, refer to the “Troubleshooting”
section in SkyPilot Network Administration. There you’ll find
troubleshooting procedures for:
•
Power-on problems
•
Ethernet connectivity problems
•
IP connectivity problems
•
SkyGateway transmission problems
•
Link failure problems

A
Grounding Guidelines
This appendix provides some guidelines for properly grounding the
SkyPilot Connector.
Proper grounding protects both your SkyPilot device and equipment
connected to it. For the surge protection circuitry built into the
SkyPilot equipment to be effective, proper grounding of the unit is
necessary. This is especially true if you’re installing devices on tall
structures, or in areas subject to lightning.
NOTE The techniques described in this appendix are intended as
general guidelines only and do not constitute a comprehensive
guide covering all installation scenarios. For maximum
protection, contact a qualified installation specialist who is
familiar with your operating environments. If lightning is a
threat in your area, consider a consultation with a lightning and
transient protection specialist.
General Grounding Strategy
To ensure optimal reliability, properly ground the metal base of the
SkyPilot device. The most efficient way to ground the device is to use
an 8 GA or larger wire to connect it to a ground point on the structure
or tower.
The three most common ground points are:
•
A cold-water pipe. Make sure it is well connected to earth.
SkyPilot SkyAccess DualBand Installation
43
•
The primary grounding point of the AC electrical system of the

A 10-foot or longer copper-clad ground rod driven into the earth.
For a tower with multiple legs, you need one ground rod per leg and
a ground wire loop connecting each of the rods; see Figure 12.

Making Connections “Gas-Tight”
Regardless of the grounding point you use, make sure the connections
are “gas-tight” - capable of retaining low resistance and integrity over
time and with exposure to the elements.

Use of an antioxide compound and proper sealing is essential. For
protection against corrosion, wrap all connections with Scotch® 130C
tape.
Checking Cold-Water Pipe Integrity
If you’re using a cold-water pipe for grounding, verify the integrity of
the ground. In some cases, sections of metal cold-water pipes may have
been repaired or extended with PVC material. PVC material or a
dielectric union will render a cold-water pipe ground unacceptable for
grounding.
Measuring Resistance
Verify that there is no more than 5 ohms of resistance between any two
ground points in the entire system. Also make sure that all ground
points on a structure are tied together. For example, if you use a
ground rod and a cold-water pipe as grounding points at different
locations on the same structure, you must tie them together.
Adding Surge Protection
If you’re installing a SkyPilot device in an area that’s subject to
lightning storms, SkyPilot recommends installing a surge protection
device (SPD) at both ends of the Ethernet cable - one at the SkyPilot
device and one at the point of entry to a building or enclosure.
SkyPilot offers SPDs with bracket and cabling designed for use with
SkyPilot equipment. For more information, visit SkyPilot customer
support at www.skypilot.com/support/ to view accessory guides for
SkyPilot-branded surge protection solution. (You may also purchase
SPDs from third-party vendors.)

Grounding Checklist
When grounding a SkyPilot device, use the following checklist to
confirm that your installation is adequately protected from power
surges and lightning.
•
Connect a ground wire from the SkyPilot device to a ground system
on the building or tower.
•
Use shielded CAT5 cabling and connect the drain wire of the shield
to ground at the SkyPilot device. (Leave the other end of the drain
wire unconnected.)
•
Use the proper size down lead to connect a SkyPilot device on a
roof or tower to the ground system of indoor equipment.
•
Verify that all points of the ground system are tied together with
less than 5 ohms resistance between any two points.
•
Run the CAT5 cable inside the tower structure, tying the cable to
the tower leg at every 4 feet of length. For increased protection,
run the CAT5 cable through metallic conduit installed on the tower.
•
Bleed off any static charge by installing a streamer-delaying, staticdissipation array above the SkyPilot device.
•
Install all lightning and surge protection devices in accordance with
UL 96A installation requirements for lightning protection systems
and the NFPA 780 standard for lightning protection.
