1           Canopy System Description
1.1         Introduction
            The Motorola Canopy™ Wireless Internet Platform is a broadband wireless communication
            system that supports high-speed Internet access. With the Canopy platform, Motorola brings
            radio technology to the Internet service provider marketplace. It is simply one of the best
            solutions for providing high-speed wireless Internet to customers. The Canopy system is
            available in a variety of configurations. This section provides a brief overview of the Canopy
            system and details the configurations and their associated components. implementation.

1.2         Canopy System Overview
            The Canopy system, Motorola’s innovative wireless broadband solution, is the ideal
            technology for developing, enhancing and extending advanced broadband networks and
            services. The Canopy family of products is comprehensive in nature — includes products in
            the 900 MHz, 2.4, 5.2, 5.4 and 5.7 GHz frequency bands —and makes the delivery of high-
            demand services like broadband Internet access, voice over IP (VoIP), video services,
            security surveillance and T1/E1 capabilities both much quicker and much less expensive to
            Figure 1 depicts how the Canopy system can be configured to serve geographically diverse
            regions — from densely populated urban centers with multiple dwelling units (MDUs) to
            remotely located towns and villages with high degrees of foliage — with wireless broadband
            services under a single network. Motorola recommends selecting products in the 5.2 and/or
            5.7 GHz frequency band to serve as the network backbone and augmenting the system with
            products in the 900 MHz and 2.4 GHz frequency bands to extend coverage in difficult to
            reach areas.

1.3         Components

            The following sections highlight each of the Canopy components:

1.3.1       Access Point (AP) Cluster
            The AP Cluster is a base station that incorporates between one and six AP modules and up
            to two Backhaul (BH) modules. Each AP module operates with a 60-degree directional
            antenna to provide coverage to a single sector. Figure 3 shows the Canopy AP Cluster.

                   Figure 3: The Canopy System Showing the AP Cluster, CMM and GPS

            One of the unique capabilities of the Canopy system is its ability to synchronize the
            transmission timing of the AP modules in all of the AP Clusters. The Global Positioning
            System (GPS) receiver in the Cluster Management Module (CMM), shown previously in
            Figure 3, is the key to delivering this system level synchronization. The synchronization of
            the AP transmission along with the specially designed Canopy Time Division Duplex (TDD)
            air interface ensures that all AP modules transmit at the same time while all SMs are in a
            listen mode. This synchronization also ensures that when the SMs are transmitting, all of the
            AP modules are listening.
            Enabled by the CMM synchronization ensures that the Canopy system does not interfere
            with itself, since the AP modules do not interfere with each other and the SMs do not
            interfere with each other. This unique characteristic enables the operator to effectively scale
            the network without requiring complex system planning. Canopy AP Clusters can be easily
            added to the network to improve system coverage or capacity without increasing system
            The AP Module operates with a raw data rate of 10 and 20 Mbps and has a range of
            approximately two miles to ten miles (with reflector), working in the following frequencies:
            900 MHz and 2.4 GHz ,
            5.1 GHz, 5.2 GHz , 5.47 GHz and 5.7 GHz. Each AP requires a 24-volt power source and
            uses a single 10/100 BaseT Half/Full duplex connection to interface into the CMM or
            appropriate network connection.

            Some Canopy types such as 2.4GHz or 5.4 GHz system also supports adjustable power and
            can be attuned from ten milliwatts to one watt in one decibel increments to meet the specific
            requirements of the installation.
            The AP Cluster has eight usable ports that may be configured to contain five main
                 Cluster Management Module (CMM)
                  - GPS Receiver
                  - Hardened Ethernet Switch
                  - Power Supply
                 AP Modules (A cluster can support up to six APs)
                 Surge Suppressor (A single cluster requires one surge suppressor to protect the
                  network connection to the CMM when the BH module is not used with the CMM.)
                 BH Modules
                 Power Source (the AP Cluster is powered by the CMM which requires a 110 or 220 VAC
                  or 24 VDC power source)

            The Universal Mounting Bracket (SMMB1) is available for mounting the AP Module at the AP
            Cluster. One SMMB1 per AP module is required.
            The AP modules in the 2.4,5.1, 5.2, 5.4 and 5.7 GHz frequency bands are equipped with
            integrated patch antennas. All of the Canopy AP modules are available in the standard
            Canopy platform as well as the Advantage platform with the exception of the 900 MHz
            products. All Canopy 900 MHz products with software release 6.0 and beyond are built on
            the Canopy Advantage platform. In addition, the Canopy 900 MHz APs are available in two
            versions: connectorized (external antenna) and integrated (built-in antenna).will be described

1.3.2       Subscriber Module (SM)
            The Canopy SM, as shown in Figure 4, is the subscriber termination unit or the Customer
            Premise Equipment (CPE). It consists of a single module that operates with an integrated 60-
            degree antenna (2.4, 5.2, 5.4 and 5.7 GHz).

                                    Figure 4: The Canopy Subscriber Module (SM)
Motorola Confidential Proprietary

            Each SM can communicate to a single AP module at any given time. SM synchronization
            and control is accomplished via the received AP signal. SMs are typically located outdoor
            and Line of Sight (LOS) from the APs. Once an SM is initialized, it scans the Radio
            Frequency (RF) channels and automatically registers with the appropriate AP.
            Each SM requires a Category 5 cable for its Ethernet connection to the premise IP
            equipment with DC power supplied to the SM through that same cable (POE). The
            9000APC/9001APC also has a 16 inch (approximately 40 centimeter) cable with a male N-
            type connector for connecting to an external antenna.
            The SM uses a 110 VAC power supply (ACPS110-03) or the 90V-230V switching power
            supply (ACPSSW-02 (not country specific), ACPSSW-03 (Argentina), ACPSSW-04
            (Australia), ACPSSW-05 (China) and associated RJ45 connector to power the SM. The
            Universal Mounting Bracket (SMMB1) is available for mounting the SM to the customer site.
            One SMMB1 is required for each SM. The Universal Mounting Bracket is designed to hold
            one subscriber module. It was not designed for holding both the module and a connectorized
            antenna. Motorola also recommends using a Canopy Ethernet Surge Protector (300SS)
            mounted at the Ethernet entry point on the outside wall of the premise.
            The 900 MHz SM with external (connectorized) antenna is shown in Figure 5. A professional
            installer is required for the connectorized SMs. The same guidelines and performance apply
            for the 900 MHz subscriber module as those shown in the 900 MHz access point.

1.3.3       Backhaul (BH) Module
            The Canopy BH module is a point-to-point radio that carries traffic between two points. In the
            Canopy system a backhaul link is used to provide bandwidth to and from AP Clusters. A set
            of point-to-point BH modules can also be used as a low latency Ethernet bridge between any
            two networks or between a network and a single remote computer. In the event, a
            convenient fiber or cable connection is not available for IP connectivity to an AP Cluster a set
            of BH modules can be used.     10 & 20 Mbps Canopy Backhaul Modules
            Each 10 and 20 Mbps BH module, illustrated in Figure 6, communicates to another BH
            module using a highly directional antenna. The 10 Mbps BH module operates with a raw
            data bit rate of 10 Mbps with an aggregate throughput of 7.5 Mbps and has a maximum
            range of approximately 35 miles (56 kilometers) when using the reflector. The 5.2 GHz
            Extended Range 20 Mbps BH module provides an aggregate throughput of 14 Mbps when
            using the reflector. Details for throughput and range of the BH modules are contained in this
            The uplink/downlink bandwidth ratio for a single BH link is configurable by the operator (i.e.
            75 percent downlink and 25 percent uplink or 50 percent uplink and 50 percent downlink –
            set at timing master). When two BH pairs are configured back-to-back in a daisy chain
            configuration, they each need to be configured for symmetrical load with 50 percent allocated
            for uplink and downlink. Each BH module receives its 24 VDC power from a 110-power
            supply (ACPS110-03) or the 90V-230V switching power supplies (ACPSSW-02 (not country
            specific), ACPSSW-03 (Argentina), ACPSSW-04 (Australia), ACPSSW-05 (China)) and
            associated RJ45 connector. The BH module can also be connected to the CMM, which will
            supply power to the BH module and networking with the AP modules at the AP Cluster.

                          Figure 6: The Canopy 10 & 20 Mbps Backhaul (BH) Modules
Motorola Confidential Proprietary     30 Mbps and 60 Mbps Backhaul Modules
            The Canopy system also offers a 30 Mbps and 60 Mbps Backhaul modules for applications
            that require greater throughput and further distances in line-of-sight and non-line-of-sight

            Figure 7: The Canopy 30/60 Mbps Backhaul (BH)
            Module with Integrated Antenna

            Unlike other Canopy backhaul modules, the 30/60 Mbps BH modules are sold in pairs and
            do not support the use of a reflector. To ensure a secure connection, each pair of modules is
            preset with its own built-in IP address. The backhaul modules also contain the corresponding
            MAC address for its mate. The preset addresses enable the system’s security features and
            ensure that the two backhaul modules can communicate only with one another.
            The 30/60 Mbps BH combines multi-beam antennas, space/time coding, Orthogonal
            Frequency Division Multiplexing (OFDM), adaptive modulation and Dynamic Frequency
            Selection (DFS) to deliver a robust backhaul solution in a small integrated package.
            Encryption is provided via a built-in proprietary scheme.
            The 30 Mbps and 60 Mbps BH systems support
            aggregate throughputs of up to 21 Mbps and 43
            Mbps respectively, and a range of up to 124 miles
            (200 kilometres) line of sight (LOS). Data rates are
            variable and will decrease with an increase with
            link distance and in range or the number of
            obstructions encountered by the system. To
            accurately estimate throughput based on distance
            and topographic features and obstructions,
            Motorola recommends use of the backhaul link
            estimator to accurately gauge the system’s
            performance in certain situations.
            Each 30/60 Mbps integrated BH includes
            integrated antennas, indoor power unit, mounting
            hardware, quick start guide and CD containing
            user guide and software. The 30/60 Mbps
            connectorized BH contains all of the same
            elements as the integrated with the exception of
            the antennas which are sold separately.

1.4         Throughput & Range Point to Point
            Table 1 details the throughput and range for the Canopy systems in point-to-point
            configurations. Operating range and data throughput of wireless communication are
            dependant on terrain, foliage and background RF energy, among other conditions. Motorola
            strongly recommends network operators perform a physical and radio frequency site survey
            to take these factors into account.

1.5         Throughput & Range Point to Multipoint
            Table 2 details the throughput and range for the Canopy systems in a point-to-multipoint
            configuration between the standard Canopy and Canopy Advantage platforms. Operating
            range and data throughput of wireless communication are dependant on terrain, foliage and
            background RF energy, among other conditions. Motorola strongly recommends network
            operators perform a physical and radio frequency site survey to take these factors into

1.6         Motorola Canopy Advantage Element Management System
            Motorola recognizes that low cost centralized management is essential for common carriers
            and the ability of an operational network to grow ever larger (scalability). For this common
            carrier management need Motorola provides two servers, both in the form of software, to be
            installed on common carrier-provided Intel PC platforms. Either Windows or Linux operating
            systems may be specified.
            The two Canopy servers are termed the Bandwidth and Authentication Manager (BAM) and
            Prizm, respectively. The latter is the Canopy Advantage Element Management System
1.6.1        BAM- Bandwidth and Authentication Manager
            A centralized view of a broadband wireless network is required for operators to manage
            resources efficiently. With this is mind, the Motorola Canopy system is enhanced with
            network management tools that improve the installation process, security management and
            network operations.
            The Bandwidth and Authentication Manager (BAM) augments the Canopy systems
            embedded encryption capabilities. The BAM contains additional layers of security to restrict
            access to system data. It is the central point of authentication for subscribers. Through the
            effective use of the BAM in a network, operators can successfully:
                 Offer Tiered Services: Apportioning bandwidth to businesses, Small Office Home
                  Office (SOHO) and residential customers based on demand.
                 Increase Security Levels: Requiring positive authentication from a central control
                 Manage Network Assets Efficiently: Controlling license management from a central
1.6.2       Prizm
            Prizm allows for Simple Network Management Protocol (SNMPv2c) centralized management
            of all Canopy Advantage network elements: CMM, AP, SM, and BH. It is a state-of-the-art
            Element Management System (EMS), allowing sophisticated centralized operational
            knowledge and control on an operator’s entire BWA network.
            Again, like the BAM environment, any authorized administrative computer may communicate
            to Prizm for network management purposes; only a web browser with JAVA and PERL
            capability is required. Both Windows-based and Linux-based ―
1.6.3       Comprehensive Migration Path to Unlicensed WiMAX
            Motorola’s vision includes the delivery of a WiMAX compliant Canopy access point for the
            5.8 GHz frequency band. The Canopy WiMAX access point, which is key to this vision, will
            be capable of simultaneously operating Canopy’s best-in-class interference mitigation
            techniques, currently available in the Canopy system, as well as Orthogonal Frequency
            Division Multiplexing (OFDM) — as dictated by the 802.16-2004 standard — in the 5.8 GHz
            frequency band. This means a Canopy WiMAX access point will be capable of
            communicating with subscriber modules from the Canopy, Canopy Advantage and Canopy
            WiMAX platforms as well as with third party WiMAX Customer Premise Equipment (CPE).
            The Motorola Canopy WiMAX products are envisioned to embody the same ―look and feel‖
            as the original Canopy products. This is not a chance event! Motorola anticipated what is
            now called WiMAX in the late 1990s, and embarked upon a product development cycle that
            now enables our WiMAX product to be years ahead of the competition, a great benefit to a
            common carrier with time-to-market challenges. Consequently Motorola only had to re-
            engineer certain details of our pre-WiMAX product in order to produce WiMAX compliant
Motorola Confidential Proprietary

            One might ask, ―Why is this important?‖ Quite simply, WiMAX based OFDM systems offer
            considerable benefits in terms of speeds and throughput but can come at a cost in their
            ability to effectively mitigate interference. While this is not an important consideration in
            licensed frequencies where the spectrum is allocated for very specific usages, it is extremely
            important in unlicensed frequencies where interference can easily cripple a system that is not
            effectively protected. Motorola’s approach assures that our customers can take advantage of
            the benefits of both WiMAX and Canopy’s superior interference techniques which ensures an
            outstanding end user experience.
            With the Advantage platform, Canopy equipment users will be able to enjoy all of the
            strengths of the Canopy Advantage and Canopy WiMAX platforms (as they become
            available) at the same time, under the same access point, the same frequency and the same
            tower — essentially, a single wireless network infrastructure serving your broadband needs.
            Today, operators around the world can deploy the Canopy Advantage system with the
            knowledge that Motorola is providing an effective migration path that will take them to
            WiMAX, if desired, while protecting the investment in the CPE.
1.6.4       Summary- Canopy Advantage
            Canopy Advantage is the second generation of Motorola BWA product, incorporating all the
            lessons learned and operational experience of our many common carrier customers. Over
            250,000 Canopy network elements are in operation around the world. Advantage effectively
            doubles the performance of the first generation of Canopy at only marginal increases in cost.
            The use of unlicensed spectrum in the common carrier business environment is relatively
            new, but its low cost and robustness in operation have made unlicensed spectrum an
            increasingly viable business practice. It works, and the price is right.
            Motorola is also committed to providing standardized WiMAX for licensed spectrum as well,
            and is evolving the current Canopy Advantage in that direction. However, WiMAX, if WiFi’s
            history is any guide, will have a long germination period.
            Consequently Motorola strongly encourages common carriers plan, install, and operate
            Canopy Advantage as ―pre-WiMAX‖ service offerings, which already provides all the useful
            BWA features as determined by operating companies.

                  for delivering high quality services such as VoIP and online gaming.
                 Seamless Integration: All subscriber modules currently in the field can easily be
                  upgraded, via software download, to take advantage of the benefits of the Advantage
                  platform when used with a Canopy Advantage Access Point.
