1 Introduction
The SkyPilot CPE (SC1000) provides a subscriber interface to a SkyPilot wireless
network. The SkyPilot CPE connects either to a SkyPilot Seed (SD1000) or directly to a
SkyPilot Gateway (GW1000) device. The SkyPilot CPE operates in the unlicensed
5.8GHz UNII band and comes in Indoor and Outdoor variants.
The Indoor and Outdoor SkyPilot CPE differ only in the external mechanical packaging.
The Indoor CPE is housed in an attractive plastic package that may be installed in a home
or office environment. The Outdoor CPE utilizes a fully environmentally sealed housing
that supports extended temperature range operation.
The combination of the SkyPilot wireless network elements provides a high capable and
flexible system. The system and CPE offer:
• High Capacity and Long Range
OFDM technology, a large link budget and modulation rates of 6-54Mbps, provide
reliable Non-LOS operation and market leading capacity.
• Meshing
The system offers the flexibility of subscriber CPE (SC1000) connection directly to a
SkyPilot Gateway (GW1000) or via an intermediary Seed (SD1000), resulting in
vastly increased coverage when compared to typical point-to-multipoint systems.
• Standards Based
The SkyPilot system is based very closely on the 802.11 standard and utilizes
commercial chipsets. SkyPilot has implemented significant enhancements that
provide range and performance advantages.
• Easy Installation
The SkyPilot Indoor CPE allows for very simple, end-user install. The compact,
environmentally hardened Outdoor CPE is easily installed on a rooftop or under eave.
• Networking
The SkyPilot system implements an intelligent, Ethernet switching network, with a
10/100bT bridge interface provided by the Gateway and CPE. Subscriber rate control
and traffic prioritization QoS mechanisms are supported, along with optional VLANs.
In addition, there is support for configurable protocol filtering and Access Control
Lists (ACL).
• Security
AES link encryption and complete node authentication with optional support for full
MD5 certificates.
• Network Management
Both node types are fully manageable via SNMPv2c and a Command Line Interface
(CLI). Static or DHCP IP address allocation is supported.

1.1 Outdoor CPE
The Outdoor CPE is a fully integrated, environmentally hardened device providing the
interface between a wireless SkyPilot network and the local subscriber. The subscriber
connection is via a single 10/100bT Ethernet port. The CPE connects to the SkyPilot
network via a single, optimized wireless link.
The SkyPilot Outdoor CPE houses a single high gain panel antenna providing 30°
horizontal coverage and a 6° vertical angle, along with all RF and digital circuitry. The
Outdoor CPE utilizes Power over Ethernet (PoE), meaning that just a single cable is
required to install the unit.
The Outdoor CPE is equipped with high-visibility LEDs that provide wireless
connectivity feedback during installation. The Outdoor CPE may be monitored and
managed remotely by the operator via SNMP and the embedded Command Line Interface
(CLI).

1.2 Indoor CPE
The Indoor CPE contains the same antenna and circuitry as the Outdoor CPE. The
external mechanicals are replaced with an attractive, consumer friendly plastic housing.
The Indoor CPE may be used with either the desk or window mount provided.
The LEDs provide feedback allowing for the easy placement and pointing of the unit. As
with the Outdoor CPE, the Indoor unit provides full operator monitoring and
management.

2 Network Architecture
The SkyPilot CPE (SC1000) combines with the Gateway (GW1000) and Seed (SD1000)
to create a robust, high capacity wireless network. All wireless links within the network
are established and optimized automatically. Seed units allow for expanded coverage and
permit multiple paths through the network. A highly efficient routing algorithm selects
the best path for user traffic and heals around any network failures.
2.1 Link Establishment
A Gateway is configured for a given channel within the UNII band and signals its
presence through the use of a periodic beacon message transmitted on that configured
frequency. Seeds that have successfully connected to the network also transmit a periodic
beacon message.
Upon power-up, the CPE listens for beacon messages generated by the Gateway and
Seeds. The receive signal strength of these beacons is indicated by the LEDs. This LED
indication allows the installer or end-user to position the CPE for optimum link
performance. The CPE and Gateway or Seed automatically complete link optimization.
This ensures the selection of optimal Gateway/Seed antenna and modulation rate. The
SkyPilot units support modulation rates of 6-54Mbps and the highest, reliable rate shall
be selected through the exchange of test packets. Note that established links are
continually monitored and periodically optimized.
2.2 Bandwidth Allocation
The SkyPilot system implements a synchronization of the 802.11 protocol. This
synchronization allows for the establishment of individual links between nodes utilizing a
unique timing and antenna combination. In addition, highly accurate traffic rate and jitter
control is enabled.
The initial release of the SkyPilot system provides rate control for subscriber traffic both
in the downstream (Gateway to CPE) and in the upstream (CPE to Gateway) direction.
The maximum rate downstream and upstream rate can be specified for each subscriber. In
conditions of over-subscription when the overall bandwidth demand is higher than the
system capacity, the individual subscriber data rates will be reduced proportionately. i.e.
a configured 2Mbps is reduced to 1.5Mbps while a configured 1Mbps rate is reduced to
750kbps.

2.3 Networking
The SkyPilot system operates as a Layer 2 network. The Gateway and CPE have an
Ethernet bridge. All upstream subscriber traffic is direct out the Gateway Ethernet port
and to external switch or router.
All SkyPilot network elements implement a SNMPv2c agent. In addition, there is also a
CLI that may be access locally via a serial port or remotely via Telnet. In order to support
these interfaces, an IP address must be allocated. This allocation can be done dynamically
via DHCP or may be statically configured. See Section 4 for details.

3 Installation
The SkyPilot CPE is designed for a wide range of installations. The Indoor CPE can be
user installed in a home or office. The Outdoor CPE can easily be installed on the roof or
exterior wall of an office, apartment build or single family home. The Outdoor CPE can
also be very easily installed on a light or utility pole.
3.1 Indoor CPE
3.1.1 Mounting
Before mounting the Indoor CPE the user must first find an appropriate location within
the home or office building. In the case where there is limited Gateway/Seed coverage,
the operator may aid this process by providing general pointing instructions. i.e. Point
CPE in a West to Northerly direction. The user should avoid installations heavily effected
by localized foliage or other obstructions, and should select upper floors if possible.
The user should power the CPE (See Section 3.1.2 for details) and place the unit in
window. Once the CPE has successfully initialized, the beacon signal strength shall be
indicated by the WAN Activity LED (LED 4). The faster the cadence, the higher the
receive power. Ideally, the user shall test the CPE in multiple locations selecting the one
with the highest reported power level. The Indoor CPE LEDs can be seen below.

Once the best location has been identified, then the user must mount the CPE. If there is a
suitable desk, bookshelf or other flat surface, then the desk mount may be utilized. The
user should set the CPE in the cradle, ensuring the front of the unit is pointing toward the
window. The CPE can be fixed in position by tightening the mounting knobs.
If there is no suitable flat surface, then the user should install the window mounting
bracket. This can be installed on a window ledge or on the side or top of a window frame.
The CPE is then attached to the bracket via one of the supplied mounting knobs. Note
that the CPE must always be mounted vertically.

3.1.2 Cabling
The Indoor CPE utilizes Power over Ethernet (PoE) provided by the included Power
Injector. Note that the CPE should be installed with the SkyPilot provided Power
Injector only. The use of other PoE Power Injectors could result in damage to the unit.
The Power Injector has three connections:
1. Power – receives power from the Power Supply.
2. CPE Connector – connects the Power Injector to the CPE via a supplied Cat5.
This connection carries both 10/100bT Ethernet and power to the CPE.
3. LAN Connector – provides a 10/100bT Ethernet connection for the subscriber.
This connects to a PC or local router/switch device.
When locating and mounting the CPE, the user should power the Power Injector via the
Power Supply and power the CPE via PoE 10/100bT interface.

3.2 Outdoor CPE
3.2.1 Mounting
As with the Indoor CPE, the appropriate location for the Outdoor CPE must be found
before mounting. Link quality is generally improved with an installation as high and as
free of obstruction as possible.
The installer should power the CPE and, using the LED indication (LED 4), find the
location and direction with the best signal strength. As previously noted, knowledge of
Gateway and/or Seed location(s) can speed this process.
Having found the best location for link quality, the Outdoor CPE can easily be mounted
on a standard 1.25 inch diameter pole. Any mounting system that meets local wind-
loading regulations will be satisfactory. The photograph below shows a typical rooftop
unit installation.

3.2.2 Cabling
The Outdoor CPE is cabled in the same manner as the Indoor CPE. Note that it is
recommended that the Power Injector is located indoors or a suitable weatherproof
enclosure. The Outdoor CPE has a weatherproof 10/100bt Ethernet interface that includes
a rubber gasket and metal cover. First the Cat5 Ethernet cable is inserted.
The gasket is then placed around the cable.
Finally the bottom cover is attached with the screws provided.

4 Configuration
The SkyPilot system requires minimal configuration before service can be offered. There
is the option to utilize the SkyPilot Provisioning Server or to manual configure. The
Provisioning Server, with its interface to an SQL database facilities the configuration of
large scale networks. The Provisioning Server is the topic of a separate document. This
document shall focus on the manual configuration of CPE (SC1000) units.
4.1 CPE Configuration
A CPE must be configured for the following:
1. IP Address Mode – DHCP or Manual
2. Management IP Address and Mask (if manually configure)
3. Ethernet Port Control
4. QoS Data Rates
4.1.1 IP Address Management
The CPE management interface (SNMP, Telnet) requires the allocation of an IP address.
It can be configured to use either DHCP for dynamic IP address allocation or can be
statically configured via the CLI.
DHCP is the default. For static allocation the IP Address, Netmask and IP Default
Gateway must be input via the CLI. See Section 5 for details.
4.1.2 Ethernet Port Control
The CPE allows for the disabling (and enabling) of the 10/100bT Ethernet port. Default is
disabled. The enable/disable Ethernet port facility can also be used to control subscriber
access.
4.1.3 Subscriber Data Rates
The CPE allows for configuration of maximum downstream and upstream data rates. The
values relate to traffic sent and received over the Ethernet port.
