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 deploy. 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. Figure 1: The Canopy System Serves Geographically Diverse Communities Canopy wireless broadband technology combines carrier-grade toughness with exceptional performance, security, ease-of-use and cost effectiveness. It significantly reduces the time to design and deploy new commercial and enterprise broadband networks. It also seamlessly Motorola Confidential Proprietary integrates with existing network systems and management tools to make extending and augmenting existing service simpler and less cost-intensive. As shown in Figure 2, the Canopy system has five basic building blocks: The Access Point (AP) Cluster Subscriber Module (SM) Backhaul (BH) Module Cluster Management Module (CMM) Surge Suppressor 1 to 6 Units 3.5 Miles Up to 2 Miles GPS Antenna GPS Receiver Cluster Management Hardened Ethernet Switch Module (CMM) Power Supply 60 Degree Coverage Wedge 360 Degree Coverage Subscriber Modules Power Supply Network Connection Figure 2: The Motorola Canopy System All Canopy radios are approved by the United States Federal Communication Commission (FCC) Part 15, Class B, and RSS-210 of Industry Canada (IC). The Access Point (AP), Subscriber Module (SM), Backhaul (BH) Module and surge suppressors are all UL approved. Not all frequencies are available for wireless broadband usage in every country. For example, the 5.4 GHz radios are not available for use in the United States. For further details, please consult with the appropriate regulatory agency in the specific country. Motorola Confidential Proprietary 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 interference. 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. Motorola Confidential Proprietary 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 components: 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 later. 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. Figure 5: The Canopy 900 MHz Subscriber Module with Connectorized Antenna Motorola Confidential Proprietary 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. 220.127.116.11 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 document. 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 18.104.22.168 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 conditions. 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. Figure 8: The Canopy 30/60 Mbps BH with Connectorized Antenna Motorola Confidential Proprietary 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.

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.

This release is available at no charge to Canopy customers. All other Canopy field deployed SMs can also be upgraded to Canopy Release 6.0 and when coupled with an Advantage AP can take advantage of the increased throughput and reduced latencies. Motorola Confidential Proprietary 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 (EMS). 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 point. Manage Network Assets Efficiently: Controlling license management from a central location. 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 equipment. 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. High Performance: Very small latency (5 to 7 milliseconds). Lightning Fast Speeds: High throughput of 7 Mbps and 15 Mbps to a single Access Point. True Quality of Service: Enables operators to provide differentiated levels of service using Committed Information Rate (CIR) and Maximum Information Rate (MIR). MTBF – 350,000 Hours (40 Years!!!) Carrier to Interference (C/I Ratio) - less than 3dB!!! Built in Encryption – DES and AES encryption built in Comprehensive Multi-Services Platform: An ATM frame structure uses small frame sizes which reduce retransmission times and provides for low latency - a critical component 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.
