2 SYSTEM AND PRODUCT OVERVIEW 2.1 INTRODUCTION - WHAT IS A COMPACT BASE STATION? At PureWave, we believe that true broadband data networks must roll out in a completely different manner than the traditional, low-throughput cellular networks of yesterday. The traditional cellular network paradigm of colossal “macro” base stations and large cell radii developed from the need for high-coverage networks to carry low-bandwidth voice and messaging traffic. However, as the demand for data-based applications has grown, networks have quickly become congested, necessitating new wireless standards designed specifically for high-speed broadband data. Furthermore, as spectrum is always a scarce and expensive resource, the need for improved frequency re-use techniques has become more important than ever. The clear solution to this is higher-efficiency wireless standards, such as IEEE 802.16e Mobile WiMAX, and more flexible cell sizes. Where medium and high population density exists, cell sizes should be small to enable increased spectral re-use, thereby ensuring that each subscriber enjoys a sufficient amount of throughput. In such cases it may be necessary to deploy base stations on utility poles, flag poles, rooftops, small buildings, and walls. This necessitates small, pleasant form-factor base stations that can accept a variety of antenna types, both omni-directional and directional. Such base stations are often referred to as “Pico”. Because wired backhaul may not always be available in some such locations, it also suggests the need for wireless backhaul options. On the other hand, in rural areas with lower population densities, it makes more economic sense to deploy fewer base stations on higher towers or buildings, and usually with higher transmit power. This is closer to the traditional cellular approach and typically involves large, expensive, and power-hungry “macro” or “micro” base stations, often with split designs requiring both indoor and tower-top electronics. Wherever indoor components are required an operator must obtain an air-conditioned shelter, which adds significantly to the continual operating expenditures of such a deployment, and limits the deployment location. PureWave has taken a revolutionary approach in the development of exclusively “Compact” base stations. A compact base station shares the similar form-factor and cost of a Pico base station, but with the performance of a Macro base station. It is a zero-footprint device that can be fully co-located with its antennas. It is the best of all worlds, and can be flexibly deployed in Pico, Macro, and Micro type deployments. Welcome to the Revolution!
2.2 PUREWAVE QUANTUM AT A GLANCE The PureWave Quantum Family of Compact Mobile WiMAX Base Stations is PureWave’s 3rd generation base station platform, and we believe it presents what is simply the most advanced and high-performing, yet cost-effective base station solution available. The PureWave Quantum Family of base stations consists of the 2x4 (2 Transmit, 4 Receive) Quantum 1000, as well as the PureWave Quantum 2200 (2x2), 4400 (4x4), and 6600 (6x6) products. This User’s Guide covers the PureWave Quantum 2200, 4400, and 6600 products. These models are differentiated from each other only by the number of Transmit (Tx) and Receive (Rx) antennas they support. Otherwise they are functionally identical. In this User’s Guide we will, without loss of generality, refer primarily to the Quantum 6600 product. The PureWave Quantum Family of base station products is fully 802.16e (Mobile WiMAX) compliant and designed to interoperate seamlessly with standard, off-the-shelf, WiMAX-certified subscriber devices. All PureWave Quantum products feature a software-defined radio (SDR) architecture that allows them to continuously evolve and take on new features as they become available. Some of the key highlights of the PureWave Quantum Family of products include the following: • Superior Range – An antenna array of up to 6 antennas operated in concert creates tightly focused radio beams that extend the range of each base station by up to 40% or boost capacity where required. • Spectral Re-use – Sophisticated interference mitigation techniques coupled with advanced beamforming technology, both made possible by PureWave’s multiple antenna architecture, allow for simple network deployments and for improved spectral re-use. • Software Defined Radio – Protects your investment through support for over-the-air, field upgrades of existing networks as standards evolve and new features and capabilities are released. • Completely Weatherproof – PureWave Quantum base stations do not require shelter and can be installed completely outdoors. This eliminates the capital cost of building a shelter and the recurring cost of leasing or running an air-conditioned site. • Flexibly Mount Virtually Anywhere – PureWave Quantum base stations can be deployed on towers, utility poles, walls, rooftops, etc, without the need for remote RF heads. • ASN-GW Optional – PureWave Quantum base stations can operate with or without an ASN-GW, making even small deployments affordable. • Future Integrated Backhaul Options – Greatly simplifies deployments, eliminating the need for dedicated microwave backhaul links, and reduce the capital cost associated with base station deployment.
PureWave Quantum base stations can utilize virtually any off the shelf antennas, both omni-directional and sectored. However, PureWave recommends our own line of affordable, compact, multi-antenna panels designed specifically to complement the performance of our base stations. Error!

Figure 1: PureWave Quantum 6600 with 6-Antenna Panel PureWave’s carrier-grade solution includes our full-featured and highly scalable PureView NMS Network Management System, which can effectively provision and manage all base station and subscriber stations in the access network. PureView features include automatic discovery, fault management, inventory tables, configuration, and performance management. PureView utilizes full open standard SNMP on the access network side, and employs a full-featured northbound interface for connection to virtually any existing NMS. In addition to the PureView NMS, all PureWave Quantum Base Stations support a full-featured Command Line Interface (CLI) and an integrated Web Interface. The CLI is covered in depth in Error! Reference source not found.. Please refer to the PureView NMS and Web Interface User Guide’s for details on those applications. 2.3 PRODUCT SPECIFICATIONS PureWave Quantum products employ a sophisticated and flexible hardware architecture that combines multiple digital signal processors (DSPs), general purpose processors, and application-
specific hardware. Together these components deliver the processing power required to realize the high-performance required by today’s demanding applications, while yielding the flexibility to support future functionality as the needs arise. 2.3.1 Physical Interfaces The PureWave Quantum 6600 is shown in Figure 2. The PureWave Quantum product’s flexible architecture allows for a number of product variants to suite almost limitless deployment needs. The model shown includes six antenna ports, two additional ports for future wireless backhaul options, Gigabit Ethernet backhaul ports, and a DC power connector. Single or Multi-Mode Fiber backhaul and AC power options are also available. As the configuration of individual base station models vary, so will the appearance of the connector panel. All PureWave Quantum base stations include an RS-232 console port, a GPS antenna connector, a ground screw, and three high-intensity LEDs. They are described in 2 and Table 3. Note that Installation and weatherproofing must be completed by a professional installer. Please refer to the PureWave Quantum Base Station Installation Manual for detailed instructions.

The accurate computation of EIRP is essential to proper network planning and to ensuring that the system meets local and regional maximum power regulations. As indicated in Table 4, the average Tx power output at each base station antenna connector is 33dBm. The average EIRP per antenna is computed as follows: Ave EIRP per Ant (in dBm) = Ave Tx Pwr per Ant + Ant Gain – Cable and Connector Loss For example, if deployed with a 14dBi antenna connected to the base station with only a few feet of cable, the average EIRP per Antenna might be 33dBm + 14dBi – 1dB = 46dBm. The total average EIRP of the base station with all antennas combined can then be computed as follows:
Total Ave EIRP (in dBm) = Ave EIRP per Ant + 10log(Number of Antennas) For a 6-ant base station, the example above yields Total Ave EIRP = 46dBm + 7.78dB = 53.78dBm. Note that most regulations refer to Peak power, which in a WiMAX system is normally as much as 10dB higher than average power. In the case of the PureWave Quantum products the peak power can be assumed to be around 9dB higher than average. Therefore, peak EIRP may be computed as follows: Peak EIRP per Ant (in dBm) = Ave EIRP per Ant + 9dB. Total Peak EIRP (in dBm) = Total Ave EIRP + 9dB. For the above example, Peak EIRP per Ant = 46dBm + 9dB = 54dBm and Total Peak EIRP = 53.78dBm + 9dB = 62.78dBm. These equations are summarized in Table 6. EIRP Metric Formula Ave EIRP per Ant (in dBm) = Ave Tx Pwr per Ant + Ant Gain – Cable and Connector Loss Total Ave EIRP per ant (in dBm) = Ave EIRP per Ant + 10log(Number of Antennas) Peak EIRP per ant (in dBm) = Ave EIRP per Ant + 9dB Total Peak EIRP (in dBm) = Total Ave EIRP + 9dB Table 6: EIRP Calculations Note that some regulations are specified for particular channel bandwidths and/or antenna beamwidths and in such cases the allowable power should be scaled accordingly. As with the previous calculations, each case is often unique. Again, the PureView NMS provides guidance when deployed in markets where such regional regulations apply. 2.3.2.3 Smart Antenna Capabilities Beamforming is a technique that combines and focuses signals to and from multiple antennas to improve both downlink and uplink performance. On the uplink, the base station combines signals received on its multiple antennas, resulting in substantial link budget gains that improve range and throughput. MRC is the basic technique
from which more sophisticated uplink processing techniques (such as interference mitigation) are built. On the downlink (Base Station to Subscriber Station), sophisticated digital signal processing algorithms exploit information gathered during the uplink beamforming process to concentrate the transmitted RF energy from the antenna array to the exact subscriber stations locations, improving gain, efficiency, and signal to noise ratio (SNR), resulting in greater range and throughput. MIMO Matrix A utilizes a technique called space-time coding (STC), which exploits the spatial diversity of the channel to improve downlink performance. By improving data reception, it can increase range and maximize the utilization of available sector capacity. MIMO Matrix B utilizes a technique called spatial multiplexing (SM), in which multiple streams of data are simultaneously transmitted through multiple antennas and effectively separated by the receiving device. This technique can actually increase the spectral efficiency and, hence, the capacity of a system. The effectiveness of MIMO relies upon the spatial diversity inherent within the channel as well as other factors, and therefore a given technique may be more appropriate for certain users or deployments. Fortunately, PureWave Quantum Base Stations make these decisions automatically, maximizing the efficiency of your valuable spectrum. Cyclic Delay Diversity (CDD) is a technique employed by PureWave Quantum base stations to allow the power of multiple antennas to be combined in transmitting a single stream of data even when MIMO or beamforming cannot be supported (e.g., when transmitting the MAP). Spatial Division Multiple Access (SDMA) is SDMA is an advanced form of beam-forming in which multiple distinct beams are transmitted (or received) at the same time on the same frequency to (or from) multiple users. Whereas FDMA separates users in frequency (e.g., sub-channelization) and TDMA separates users in time, SDMA separates users in space. With SDMA different signals are simultaneously sent on the same frequency to different physical locations. Collaborative MIMO, also known as Collaborative Spatial Multiplexing (CSM), is a technique that, similar to uplink SDMA, allows multiple subscriber stations to transmit at the same time on the same frequency. A key difference between CSM and SDMA is, however, that CSM transmissions are specially coded and require specific support in the subscriber stations. In contrast, SDMA does not require specific support from the subscriber station.

For that purpose it requires a full eco-system involving multiple vendors and a number of components: o Radio Access Network (RAN) - Wireless BTS and Subscriber Devices (also known as the Access Service Network or ASN) o Access Service Network Gateway (ASN-GW) o Core Network - Management, AAA, TR-69, etc o Applications – To run on or connect to subscriber devices In this section we describe at a high level the different elements and their roles in the network. The architecture reference model in Figure 6 illustrates the interconnections between the various system components. PureWave maintains a catalogue of network elements that have
been tested against each other. To ensure interoperability between components, we strongly recommend that an operator choose from that list. WiMAX Subscriber Devices PureWave Quantum 6600 Base Station Figure 6 - Architecture Reference Model. Combining these devices into a network, as shown in Figure 7, an operator can offer fixed and mobile data, voice, video, and countless applications to users wherever they may be.
AASMulti-beamMaster BTSAAA ASN TR-69 EMS Figure 7 - 802.16e system implementation 2.4.1 The RAN - Radio Access Network The Radio Access Network is simply composed of one or more Base Stations with attached Antennas (or antenna array) that connect wirelessly to subscriber devices (e.g., Customer Premise Equipment (CPE), Mobile Stations (MS), etc. Depending upon its type and characteristics, a subscriber device may be self-contained (e.g., a handset) or may connect to a router or computer via its “subscriber interface”. A base station connects to the core network by means of its backhaul interface, which is fundamentally a wired interface but may itself be carried by means of a wireless link or network. The backhaul interface may connect to the core network directly, or through an Access Service Network Gateway (ASN-GW). 2.4.1.1 RAN – Base Station A Base Station has hardware, software, and mechanical characteristics that support its functional and performance requirements. Base Stations and Subscriber Stations interconnect with each other and their respective networks via sets of network, MAC, and PHY protocols.
PureWave Quantum base stations employ up to 6 transmitters and 6 receivers (depending upon the specific model) that work together to achieve unprecedented results in terms of its ability to connect to subscriber devices at greater distances and higher throughputs. All PureWave Quantum Base Stations utilize the IEEE 802.16e Mobile WiMAX standard for wireless communication with subscriber devices. Mobile WiMAX supports time division duplex (TDD) communication between a base station and multiple subscriber devices on a given channel of spectrum. In a WiMAX system the direction from base station to subscriber station is known as the Downlink (DL) and the direction from subscriber station to base station is known as the Uplink (UL). The ratio of time devoted to the DL to that of the UL is referred to as the DL:UL Ratio. WiMAX base stations utilize GPS (the Global Positioning System) to maintain tight synchronization and coordination among themselves in a network. This assures that all base stations in the network transmit and receive in harmony, as they must all utilize the same DL:UL Ratio. All PureWave Quantum Base Stations incorporate an integrated GPS receiver which must be connected to an external GPS antenna in view of a number of GPS satellites. The PureWave Quantum family of products is mobile WiMAX (802.16e) Profile C compliant and offers models that cover frequency bands from 2.3-2.7GHz and 3.3-3.8GHz. Products are available also in a Stand-Alone mode and can be operated without an Access Service Network Gateway (ASN-GW) to further reduce network costs. By maintaining strict compliance with the standards, PureWave Quantum base stations allow the maximum compatibility with a wide variety of 3rd party network elements. 2.4.1.2 RAN – Subscriber Devices A large variety of WiMAX subscriber devices are available today, including outdoor-mounted CPEs, indoor desktop units (IDUs), USB dongles, and mobile handsets. Some devices have built-in VoIP-based POTS (“plain old telephone service”) ports, and some even have built-in WiFi access points. We strongly recommend that operators select subscriber devices from PureWave’s catalog of recommended devices. That is the best way to assure compatibility and the highest possible performance. Warning: When choosing a GPS antenna, choose carefully, as there are many models in the market. Some are very cheap but also low gain and/or low quality and can easily become the point of failure of your system. PureWave recommends a high-quality GPS antenna from our product catalog. !
Outdoor Fixed Subscriber Devices: Outdoor Customer Premises Equipment (CPE) must usually be professionally installed on a house, building, pole, or other elevated location. They are used for fixed communications and usually integrate a set of high-gain directional antennas. A typical outdoor CPE is shown in Figure 8. Figure 8: Typical Outdoor CPE Indoor Fixed Subscriber Devices: Indoor CPE, also referred to as Indoor Access Devices (IADs) are rated for indoor use only and may have omni-directional antennas, directional antennas, or both. Either way, their antenna gain is normally significantly less than that of an outdoor unit. Although used for fixed communications, it has the advantage that its location may be easily adjusted for better reception. However, it is also subject to very significant building penetration loss which is avoided by an outdoor installation. Indoor subscriber devices are popular with operators since they can be shipped to (or purchased by) and installed by a customer, avoiding the need for professional installation. A typical indoor CPE is shown in Figure 9. Figure 9: Typical Indoor CPE USB and Integrated Laptop Portable Subscriber Devices: A USB-based subscriber device or a device built-into a laptop computer offers all the flexibility that users enjoy today with WiFi, but with the data rates and ranges offered by WiMAX. Due to their very low antenna gain, such a device will offer a lower range than fixed devices, particularly when used indoors, but they offer the advantage of portability. Some such devices even have integrated WiFi access points, creating a portable “Hot Spot”. A typical USB subscriber device is shown in Figure 10. Figure 10: Typical USB Subscriber Device
Mobile Handsets With the announced and soon-upcoming volume availability of mobile WiMAX handsets, users will have the ability to enjoy full broadband data services with the seamless mobility they are used to on today’s voice-centric cellular networks. 2.4.2 Core network The core network plays an important role in the 802.16e eco-system. Several elements are located in the Network Operation Center (NOC) and we briefly describe each here. 2.4.2.1 Management A Network Management System (NMS) and/or an Element Management System (EMS) provides for configuration, provisioning, and management of the base station and subscriber stations. It provides alarms, traps, statistics, and more. The PureView NMS (Figure 11) is a carrier-grade multi-platform NMS/EMS that provides all of these capabilities. Figure 11: PureView NMS 2.4.2.2 AAA An Authentication, Authorization and Accounting System (AAA) is required by 802.16e to authenticate and track subscriber devices within the network. PureWave Base Stations are tested for interoperability with several options of AAA servers: • Free Radius AAA o Version 2.1.7 Linux o Version 1.1.7 Windows • Cisco AAA (CAR-4.2) 2.4.2.3 ASN-GW An Access Service Network Gateway (ASN-GW) is designed to support connection management and mobility across sectors, cell sites, and even across service provider network boundaries (roaming capabilities). An ASN-GW can coordinate inter-base station traffic, as well as traffic between base stations and the core network. Simply, the ASN-GW is the gateway between the Radio Access Network and the Core Network.
PureWave Quantum base stations support the standard WiMAX R6 (Profile C) and, at the time of writing, have been interoperability tested with the following ASN-GWs: • WiChorus ASN-GW: Master Intelligent Packet Processor (IPP) SW version 2.1.1-193 (With Built-In Radius Server) • Cisco ASN-GW: Cisco Broadband Wireless Gateway (BWG) Release 2.0 for Cisco IOS. Version Release 12.4 (20091215:091801) PureWave Quantum Base Stations also incorporate internal ASN-GW functionality that allows them to alternatively be deployed without an external ASN-GW in small to mid-sized deployments. 2.4.2.4 DHCP A DHCP server is used to provide IP Address Assignment to subscriber stations. There are a number of ways this can be set up, depending upon the network elements in use. This topic is discussed in depth later in this manual. 2.4.2.5 TR-69 (Technical Report 069) TR-69 is a bidirectional SOAP/HTTP based protocol that is used for Over-The-Air (OTA) provisioning and software upgrade of subscriber devices. Communication takes place between subscriber devices and an Auto Configuration Server (ACS) and is transparent to the base station. 2.4.3 Applications The performance offered by WiMAX enables such a vast set of possible applications that a discussion of them here could not possibly do them justice. Categories include personal mobile broadband for data and video, VoIP, video surveillance, public safety, utilities, Smart-Grid, oil & gas, education, mining, backhaul needs, etc. The possibilites are endless. As every application is different, each requires a unique network and configuration settings to assure optimal spectral utilization and performance. In this guide as well as the PureView NMS User’s Manual we show how to bring up and configure the system under particular sets of assumptions, and we explain all the settings at one’s disposal in optimizing the network for any arbitrary application.
