SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 31 Introduction The SkyPilot Gateway (GW1000) and Seed/CPE (SD1000) provide a complete, high-performance wireless system operating in the unlicensed 5.8GHz UNII band. The flexible and highly scaleable SkyPilot system is ideally suited to a wide range of applications. The system offers: • 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 customer 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 compact, environmentally hardened, fully integrated Gateway and Seed/CPE require minimal configuration and can easily be installed on a multitude of locations. • Networking The SkyPilot system implements an intelligent, Ethernet switching network, with a 10/100bT bridge interface provided by the Gateway and Seed/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.
SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 4 1.1 Gateway (GW1000) The Gateway (GW1000) is a fully integrated, environmentally hardened device providing the interface between a wireless SkyPilot network and the Internet/Wide Area Network (WAN). The connection to the Internet is via a single 10/100bT Ethernet port. The connection to the SkyPilot Seed/CPE (SD1000) units is via multiple, individually optimized wireless links. The SkyPilot Gateway houses eight individual antenna elements providing a total of 360 degree horizontal coverage and a 12 degree vertical angle. These antennas, along with all RF and digital circuitry, are integrated in a compact, light-weight, environmentally hardened housing. Note that only one antenna is selected at any one moment in time. 1.2 Seed/CPE (SD1000) The Seed/CPE (SD1000) provides for both the extension of a wireless network and the local connection for a subscriber. It may be deployed in any of the following modes: • Seed Only An SD1000 can be deployed solely for the purpose of expanding the wireless network. In this mode, a subscriber interface shall not be provided. • CPE Only An SD1000 can be deployed solely for the purpose of providing a subscriber interface to the wireless network. The unit is installed on (or close to) a subscriber’s home or business and the 10/100bT Ethernet interface provides a high-speed network interface. • Combined Mode An SD1000 can provide a subscriber interface while also expanding the wireless network. A unit installed on a subscribers premise also provides for the expansion of the network with (typically) multiple wireless links to other units. The SD1000 is mechanically and electrically identical to the GW1000, containing the same antenna array. A single 10/100bT Ethernet port provides a subscriber interface.
SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 5 2 Network Architecture The GW1000 and SD1000 combine to create a robust, high capacity wireless network. All links within the network are established and optimized automatically. 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 installed and configured for a given channel within the UNII band - see Section 4.1.1 for details of frequency selection and configuration. This Gateway will signal it’s presence through the use of a periodic beacon message transmitted on the configured frequency utilizing a single antenna. When a Seed/CPE is installed it listens for this network beacon message. When a beacon is received, the Seed/CPE shall respond and attempt to establishment a link. Once a link is successfully created, the two units will automatically complete link optimization. This ensures the selection of optimal antenna, power setting 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 Routing Once a Seed/CPE has connected to the network it shall select a route to the Gateway. The automatic route selection considers the number and modulation rate(s) of the constituent links. Once a route is selected, all user traffic shall be forwarded via this path. Rerouting shall occur rapidly in the face of a link loss. Rerouting will also occur if a lower cost route is consistently available.
SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 6 2.3 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. See Section 4.2.4 for details of the subscriber rate configuration. 2.4 Networking The SkyPilot system operates as a Layer 2 network. The GW1000 and SD1000 have an Ethernet bridge. All upstream subscriber traffic is direct out the GW1000 Ethernet port and to external switch or router. The GW1000 and SD1000 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.
SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 7 3 Installation In a typical wide-area wireless network utilizing SkyPilot units, the Gateway is installed on the roof of a tall building or tower. The direct coverage area of the Gateway is generally proportionate to the height of the installation. A Gateway may also be used in smaller scale networks. Examples include high-capacity business or academic campus interconnection, or a localized access network. In this case, the Gateway could be installed on a local, medium height building or utility pole. As previously mentioned, the SD1000 maybe deployed as a CPE, in which case it is installed on a customer location, or as a Seed device. As a Seed device it may be installed on medium height buildings, or utility poles. 3.1 Unit Mounting A mounting bracket is provided with the GW1000 and SD1000 units. This bracket fastens to a standard 1.25inch diameter pole. Any mounting system that meets local wind-loading regulations and provides a 1.25inch diameter by 5inch long connecting surface will be satisfactory. The photograph below shows a typical rooftop unit installation.
SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 8 3.2 Cabling GW1000 and SD1000 both support Power over Ethernet (PoE) utilizing the Power Injector provided. Note that the GW1000 and SD1000 units should be installed with the SkyPilot provided Power Injector only. The use of other PoE Power Injectors could result in damage to the unit. Both units provide a 10/100bT connector and an RJ45 serial interface. The 10/100bT Ethernet port provides interconnectivity for user and network traffic, while the serial port is used for local access to the CLI. The photograph below shows the Ethernet port on the right and the serial port to the left. In order to ensure full weatherproofing, the grommet provided must be installed. The Ethernet cable should first be connected and then pushed into the slit in the gasket and then the gasket is pushed into the opening in the base. See the photograph below.
SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 9 Finally the cover is installed using the provided screws. The Ethernet cable is position to pass through the insert in the cover. It is highly recommended that the cover and gasket be fitted in a Seed Only application (i.e. no subscriber or WAN interface). Once the node is installed, it is recommended that the Ethernet cable be secured to prevent strain (particularly installations exposed to high wind conditions). The photograph below shows an example were the cable is secured to the mounting pole.
SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 10 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 GW1000 and SD1000 units. 4.1 GW1000 Configuration The Gateway must be configured for the following: 1. Frequency 2. IP Address Mode – DHCP or Manual 3. Management IP Address and Mask (if manually configure) 4. Ethernet Port Control 4.1.1 Frequency The Gateway supports all standard 802.11a UNII channels (5745, 5765, 5785, 5805MHz). In an environment free from significant interference in the UNII band four GW1000 can be utilized at a single location, each configured to use a differing channel. With its directional antenna and large link budget, the SkyPilot system is very effective in avoiding interference. However, there are situations where significant interference is present within the UNII band. SkyPilot recommends that an operator utilize a spectrum analyzer to scan the UNII spectrum prior to installing one or more GW1000. If a high level of interference is observed, then a subset of the four channel(s) should be selected. 4.1.2 IP Address Management The Gateway management interface (SNMP, Telnet) requires the allocation of an IP address. A Gateway 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.
SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 11 4.1.3 Ethernet Port Control The GW1000 allows for the disabling (and enabling) of the 10/100bT Ethernet port. Default is enabled. It is anticipated that the disabling of the Ethernet port may be used for troubleshooting purposes.
SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 12 4.2 SD1000 Configuration A SD1000 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 4.2.1 IP Address Management The SD1000 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. 4.2.2 Ethernet Port Control The SD1000 allows for the disabling (and enabling) of the 10/100bT Ethernet port. Default is disabled. The disabling of the Ethernet port is recommended in the case of Seed Only application (i.e. when there is no subscriber interface). The enable/disable Ethernet port facility can also be used to control subscriber access in the case of a CPE Only or Combined application. 4.2.3 Subscriber Data Rates The SD1000 allows for configuration of maximum downstream and upstream data rates. These values are selected from a list of defined options. The values relate to traffic sent and received over the Ethernet port and are not applicable in the case of a Seed Only application.
SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY Page SKYPILOT NETWORK CONFIDENTIAL AND PROPRIETARY 13 5 CLI The GW1000 and SD1000 both provide a complete CLI interface. This interface may be used to configure and monitor the unit. A full definition of the CLI is available – email support@skypilot.com to request a copy. As an example, the GW1000 configuration screen is shown below. All other GW1000 parameters are read-only.
