SYSTEM OVERVIEW
The ProST is an outdoor WiMAX-based customer premises equipment (CPE). The ProST, which
uses Intel Corporation’s Pro/Wireless 5116 broadband interface, connects IP-enabled devices
directly to WiMAX networks. Designed for the residential and small enterprise (SME) markets,
the device supports high-speed broadband Internet through a Fast Ethernet connection. The
ProST ensures high service availability at enhanced ranges, operating in both LOS and NLOS
propagation environments.
ProST operates in the 4.9 to 5.0 GHz ETSI frequency band in time division duplexing (TDD)
mode. ProST supports IP services at uplink and downlink over-the-air speeds of up to 37 Mbps
over a channel bandwidth of 10 MHz, and up to 18 Mbps over a channel bandwidth of 5 MHz.
ProST uses the OFDM signaling format, providing non line-of-sight (NLOS) performance. ProST
utilizes QAM, QPSK, and BPSK modulation technologies by modulating transmitted signals and
demodulating the received signals where the original digital message can be recovered. The use
of adaptive modulation allows ProST to optimize throughput, yielding higher throughputs while
also covering long distances.
ProST provides a built-in, integral antenna. Requiring professional installation, the ProST is
installed outdoors on a pole or wall, enabling optimal positioning for best reception with the BS.
Outdoor mounting of the ProST is made possible due to ProST's built-in lightning surge
protection feature (complying with Surge Immunity standard EN 61000-4-5).
ProST interfaces with the subscriber's LAN through the SDA-1 Type II (referred henceforth as
SDA-1) adapter. ProST connects to the SDA-1's 100BaseT interface port by a standard 100-
meter CAT-5 cable. The SDA-1 also provides the ProST with 10 to 52 VDC power supply.
However, as an alternative to the SDA-1 Type II adapter, Airspan offers two optional integrated
LAN switches:
SDA-4S Type II: integrated LAN switch, providing power and four 10/100BaseT ports
for interfacing with the subscriber’s network
SDA-4S/VL Type II: integrated LAN switch, providing power and four 10/100BaseT
ports with VLAN functionality for interfacing with the subscriber’s network
ProST can be managed by Airspan's AS.MAX Web-based management system using standard
Web browsers or alternatively, by an SNMP-based network management system (Netspan)
using standard and proprietary MIBs. In addition, external third-party management systems
such as HP OpenView can also manage the ProST using these MIBs.
Main Features
The ProST provides the following main features:
Full Outdoor Non-LOS Deployment: 256 OFDM
Based on field-proven ASWipLL's SPR mechanics
Integrated antenna gain of 13 dBi
Indoor Ethernet adapter (SDA-1 Type II):
oproviding power and interface termination
oup to 100-m Category 5 cable between ProST and SDA-1

System Overview

Theory of Operation
For basic operation, the ProST requires no initial configuration--simply plug and play.
Configuration is automatically performed over the air by the BS. The ProST is preconfigured by
the operator at the BS (using Netspan) with service flow parameters such as the maximum
information rate, the committed information rate, the maximum latency, and maximum jitter.
These configuration parameters are stored in Netspan's database corresponding to the ProST's
MAC address.
Before any communication between ProST and BS can occur, the ProST must be positioned in a
location that provides sufficient RF reception.
To join a network, the ProST needs to perform a few tasks. First, the "Network Entry" process
(defined in 802.16-2004) begins with the ProST scanning for a downlink (DL) signal from the
base station, and then synchronizing to the DL channel. Thereafter the ProST can start the
process of initial ranging, which alerts the BS to the presence of the ProST and establishment of
management connections to obtain basic and primary management connection IDs (CID) from
the BS. After the CIDs have been obtained, the ProST commences authorization and key
exchange. In the final stage, the ProST registers at the base station before obtaining the IP
address, time of day and the configuration file.
During Network entry, the ProST sends the BS its MAC address. The BS then accesses Netspan's
database (via SNMP) and checks whether the ProST's MAC address appears in the DB. If it
locates the MAC address, the BS retrieves all the ProST's configuration parameters (service
flows) from the DB and downloads them to the ProST device.

Getting Started
11
Torque wrench for N-type connectors (only relevant when implementing external
antenna)
Note: Airspan does not provide screws and wall anchors for mounting the ProST to the
wall. The screw size depends on the structure of the building to which the ProST is to be
attached. When selecting screw sizes, consideration must be given to the weight of the
ProST and load that may be induced in windy conditions.
Radio Site Planning
Proper site selection and planning before installing your ProST will ensure a successful
deployment of your AS.MAX system. A summary of the main site planning considerations is
provided below:
Minimum obstructions (e.g. buildings) in the radio path between base station and the
ProST
Mount radio as high as possible to avoid obstructions in the wireless path
Check possibility of future obstructions such as plans to erect buildings and trees that
may grow tall enough to obstruct the wireless path
Minimum incursions on Fresnel Zone (recommended minimum of 60% clearance of first
Fresnel Zone)
Align radio for maximizing received signal strength (RSS)
Consider nearby sources of interference that could degrade performance of radio
Mount radio as far from sources of interference as possible
Ensure base station and ProST are within maximum coverage range of reception
Maximum standard CAT-5 cable length connecting the outdoor ProST to the indoor
SDA-1 is 100 meters.
Ensure that you have sufficient wiring conduit and cable ties to channel and protect the
CAT 5 cable connecting the outdoor ProST to the indoor SDA-1.
Minimal Radio Path Obstructions
AS.MAX radios communicate by propagation of waves. Thus, ensure minimum obstructions
(from, e.g. buildings and trees) in the radio path between base station and ProST. It is
essential that the ProST is installed in such a way that the radio path with the base station
has a clear path with each other.
Fresnel Zone Clearance
There must be sufficient open space around the radio path to minimize blocking of the radio
beam. A minimum of 60% of the first Fresnel Zone of the path should be clear of
obstructions. Despite a clear line-of-sight, objects close enough to the transmission path
may cause attenuation in signal strength and an increase in signal interference. Objects
with reflective surfaces that seem relatively far away, but yet still encroaching on Fresnel
Zone, may cause these interferences.

605-0000-707 ProST 49 Installation User Guide-Rev C
12
Fresnel Zones define the amount of clearance required from obstacles. These zones are
composed of concentric ellipsoid areas surrounding the straight-line path between two
antennas. Thus, the zone affects objects to the side of the path and those directly in the
path. The first Fresnel Zone is the surface containing every point for which the distance
from the transmitter to any reflection point on the surface point and then onto the receiver
is one-half wavelength longer than the direct signal path.
One method for clearing the Fresnel Zone is by increasing the antenna height.
The first Fresnel Zone radius is calculated by the following equation:
Where f is the frequency (in MHz) and d is the distance (in meters) between the ProST and
the base station.
For example, using the formula above, a link of 4 km at 4,900 MHz produces a first Fresnel
Zone radius clearance of about 61 meters. This implies that to ensure the ground does not
enter into the first Fresnel Zone, both radios (i.e. at base station and subscriber) must be
mounted at least 20 meters above ground level (or clutter level). Typically, at least 60%
clearance of the first Fresnel Zone is considered as LOS. Therefore, in the above example, a
height of at least 36 meters (i.e. 60% of 61 meters) above ground level is sufficient for
LOS.
Multipath Fading
Some of the transmitted signals may be reflected from a nearby building, by water under
the signal path, or from any other reflectors. This reflected Some of the transmitted signals
may be reflected from a nearby building, by water under the signal path, or from any other
reflectors. This reflected ("bounced") signal can then be received by the radio receiving the
signal and superimposed on the main received signal, thereby degrading the signal
strength.
To avoid multipath fading from nearby buildings etc., Airspan recommends installing the
ProST at the rear end of buildings instead of at the front. When you install at the rear end
of the building, the front-end of the building blocks incoming signals from multipath
reflections.
Radio Antenna Alignment
Once the ProST is installed and aimed in the general direction of the base station, it is
recommended to measure the received signal strength (RSS) to determine the signal
strength received from the base station, and to precisely align the ProST for maximum
signal strength. You need to orientate (up/down, left/right) the ProST until the maximum
RSS levels are achieved, and then secure the ProST. (For viewing the received signal
strength, see "ProST Web-Based Management".
