TATION
?
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!

LANCE
The PureWave Quantum Family of Compact Mobile WiMAX Base Stations is PureWave’s 3
rd
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.

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

2.3.2.2 Computing EIRP Power
Effective Isotropic Radiated Power (EIRP) refers to the transmit power radiating out of the
antenna. 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.

The 4
th
generation of wireless mobile networks, WiMAX 802.16e, is creating high speed internet
connectivity anywhere, providing for broadband connectivity while supporting Authentication,
Billing, and Management of mobile users. 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

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.

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 3
rd
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.
