FCC Compliance
This equipment has been tested and found to comply with the limits for Class B Digital Device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures.
•
Reorient or relocate the receiving antenna
•
Increase the separation between the equipment and receiver
•
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
•
Consult the dealer or an experienced radio/TV technician for help
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the
equivalent isotropically radiated power (EIRP) is not more than that required for successful communication.
For safety reasons, people should not work in a situation where RF exposure limits could be exceeded. To prevent this
situation, the users should consider the following rules:
•
Install the antenna so that there is a minimum of 25 cm of distance between the antenna and people.
•
Do not turn on power to the device while installing the antenna.
•
Do not connect the antenna while the device is in operation.
•
Do not collocate or operate the antenna used with the device in conjunction with any other antenna or transmitter.
•
In order to ensure compliance with local regulations, the installer MUST enter the antenna gain at the time of
installation.
Any changes or modifications not expressly approved by Vecima Networks Ltd. could void the user’s warranty.
The Vecima OBR3650HP base station unit must be installed by a trained professional, value added reseller, or systems
integrator who is familiar with regulatory EIRP limits, RF cell planning issues and the regulatory limits defined by the
FCC.
WARNING
See “3.5.1 Setting the VistaMAX OBR3650HP Transmit Power for FCC Limits” on page 3-7 for
professional installation instructions regarding safe EIRP limits.

1.0 Introduction
1.1 OBR3650HP Overview
The VistaMAX Outdoor Base Station 3650 (OBR3650HP) is a WiMAX compliant low power transceiver contained in a
weatherproof sealed housing. The OBR3650HP offers a single out-of-box solution for WiMAX applications – the only
equipment required inside the base station premises is Power over Ethernet switch. The OBR3650HP is part of the
WiMAX compliant VistaMAX family of base stations, subscriber units, and network equipment available from Vecima
Networks.
The OBR3650HP operates in the 3650 to 3675 MHz band. It requires an additional indoor Power over Ethernet switch
such as the VPN100002. The WiMAX Ethernet Switch 800 (WES800) can also serve as the Ethernet switch to provide
power to sectors using the units and serve as the network connection point.

2.2.1 Water Proof the Connection
Wrapping the antenna connection with sealing tape keeps the connection tight and protects against moisture.
To water proof the connection follow these steps:
Step 1
Use a section of rubber sealing tape. Starting at the OBR3650HP end, stretch the tape and wrap it around
the connector as close as possible to the body of the OBR3650HP. Overlap the tape by approximately onehalf of its width so that it can form a seal with itself. Extend the wrapping to approximately one-inch past the
end of the connector.
Figure 2-6 Apply Rubber Sealing Tape
Step 2
Cover the sealing tape with electrical tape. Start approximately one inch further down the cable, and stretch
the tape, overlapping by one-half. Wrap to the OBR3650HP end, then without breaking the tape, wrap back
down to the cable end.

2.3.3 Grounding the Base Station
Vecima recommends grounding the base station using one of the following procedures depending on your configuration.
If you are unsure which procedure to use, use procedure B.
Procedure A: Grounding the base station so that the building and the tower share the
same earth ground:
1. Connect the chassis of the OBR3650HP to the tower via the grounding lug on the back of the unit. See “2.3.3
Grounding the Base Station”.
2. Use a shielded CAT5 cablefeed to connect the OBR base station to the surge suppressor.
3. Use an inline surge suppressor for all OBR3650HP cablefeed installations. Connect the shield of the cablefeed
to the ground lug of the surge suppressor. The purpose of the surge suppressor is to shunt to ground any over
voltage [>60] transients that may be induced on the CAT5E cablefeed via lightning or other high voltages.

Procedure B: Grounding the base station so that the building and the tower use
different earth grounds:
1. Connect the chassis of the OBR3650HP to the tower via the grounding lug on the back of the unit. See “2.3.3
Grounding the Base Station”.
2. Use a shielded CAT5 cablefeed to connect the OBR base station to the surge suppressor.
3. Use two inline surge suppressors, one for all OBR3650HP cablefeed installations at the base of the tower and
another for the first surge suppressor and the WES800. Connect the shield of the cablefeed to the ground lug
of the surge suppressor. The purpose of the surge suppressor is to shunt to ground any over voltage [>60 V]
transients that may be induced on the CAT5E cablefeed via lightning or other high voltages.

CHAPTER
3.0 Getting Started with OBR3650HP
3.1 Before You Begin
The OBR3650HP provides the base station component of the Vecima VistaMAX system. To set up and configure the
base station, you require the following:
•
One VistaMAX OBR3650HP base station with a stand-alone Power over Ethernet (PoE) or WES800 Ethernet
Switch
•
One VistaMAX outdoor subscriber station or indoor subscriber station such as the OSR3500C or ISR3510.
•
One of the following components to provide the DHCP and TFTP server:
– Vecima’s Network Management 8000
– A third-party DHCP and TFTP server as per the WiMAX standard. This setup is not covered in this manual.
Setting up the system using NMS8000
Using the NMS8000 as the provisioning tool for all OSR subscriber stations and hosts on the VistaMAX system is the
most common scenario. The platinum, gold, silver, or bronze VistaMAX starter kits available from Vecima Networks
includes an NMS8000.
NOTE
If you wish to connect Internet-accessible hosts to the VistaMAX system, you will need to provide a router with
a public IP address and a valid DNS server. When you are connecting to Internet-accessible host and using the
NMS8000, Vecima recommends connecting one of the NMS8000 Ethernet interfaces on a public routeable IP
address.

3.2 Overview of Configuration
The following steps outline the process for configuring a VistaMAX system. This process assumes that you are using an
NMS8000.
Step 1
Use CAT5 straight-through Ethernet cables to connect the physical components as shown in Using
NMS8000 to Provision VistaMAX System.
Step 2
Use the Web-based interface to configure the IP addresses for the base station and subscriber station(s).
If necessary, configure the IP addresses for the NMS8000.
Step 3
Use the Web-based interface to configure the radio parameters for the base station and subscriber
station(s).
Step 4
If necessary, use the Web-based interface for the NMS8000 to add the subscriber stations on the
NMS8000.
Step 5
Establish the link between the base stations and subscriber stations and verify that the subscriber stations
are online.
The steps that pertain to the base station are described in more detail below. For more information, refer to the NMS8000
& NMS8000/SSP Network Management Server Installation and Operation Guide or related information listed
under Finding Related Documentation on page iii.
3.3 Using the Web Based Interface
The Web interface of the OBR3650HP system may be viewed with a standard web browser such as Mozilla™ or Internet
Explorer™, no additional add-ins are required.
NOTE
If your Web certificate is invalid or expired, you will be prompted to continue without the certificate or add an
exemption to the certificate.
The following are the default log on settings for the Base station Web-based interface:
•
Web-based interface access — https://192.168.101.2
•
subnetwork mask — 255.255.255.0
•
username — root
•
password — vistamax
To log on to the Web-based interface:

might be different. If you are not using the default address, contact your system administrator for the IP
address.
Step 2
Type the username root and the password vistamax to access the web GUI. The log on screen displays:
3.4 Configuring the Network
You will need to configure your network to establish communication between the network elements. Figure 3-2 shows
an example of a properly configured network. The example shows a network configuration using default values. If you
purchased a WiMAX starter kit, these value will already be set.
The VistaMAX Base Station is shipped with a default IP address. However, depending upon your network configuration,
you may want to change the IP address of your Base Station.
Figure 3-2 Network Diagram
As per the WiMAX standard, the subscriber station requires an IP address and TFTP offered to it during network entry.
To fulfill this requirement, both a DHCP and TFTP server must be present. It is possible to use a third-party customersupplied DHCP and TFTP server, but Vecima recommends using the Network Management Server 8000 (NMS8000).
Most Vecima starter kits come with an NMS as part of the solution.
NOTE
Customers who purchased the basic starter kit or who do not have an NMS must use the WiMAX-out-of-the-box
(WOOTB) procedure. For more information about WOOTB, contact the Application Engineering Support at
Vecima Networks.

3.7.7 Setting Service Flow Information
The service flow is part of the Quality of Service (QoS) feature of the base station. Service flows provide the following
functions:
•
Service flows specify a multitude of QoS parameters including: traffic priority, sustained and reserved data rates,
jitter, maximum latency, and specify security profiles.
•
Service flows are setup individually for both uplink and downlink data flows.
•
Service flows classify traffic based on Layer 2, 3 or 4 (Ethernet, IP, TCP/UDP/RTP) header information including
items such as source and destination addresses, port numbers, 802.1Q VLAN IDs, and Ethernet or IP traffic priority
levels.
Before each frame, OBR3650HP examines all of the incoming requests and grants a time to transmit for the subscriber
station based on all of the active service flow parameters to guarantee QoS where required. Individual subscriber
stations receive aggregate bandwidth grants from the OBR3650HP and must individually manage their own uplink
bandwidth usage.
Setting up a Quality of Service framework:
Step 1
Define a service class and set up its parameters.
Step 2
Define a classifier template and set up its rules.
Step 3
Create service flows and associate them with service classes and classifier templates.

terminating modular plug allowed the shielding wire to be improperly grounded, thus making the cable susceptible to
radiated interference. Without proper grounding, the presence of interfering radiation can cause the loss of data packets
between the OBR base station and the WES800.
To fix this problem, Vecima recommends reworking the termination of the Ethernet cable using the JMRJ45S-15
modular plug and properly grounding the cablefeed. The cable termination can be repaired in the field at the tower site.
Once the Ethernet cable termination is repaired, the cable feed will no longer be susceptible to interfering radiation and
the data will be secured.
Figure A-1 JMRJ45S-15 Modular Plug
NOTE
Other than the risk of data loss due to interfering radiation, there is no safety issues concerning the connector
that came with the OBR3650HP. Where loss of data due to the radiating interference is not a concern, reworking
the terminating end with the JMRJ45S-15 is only necessary as a precaution.
If using a pre-made cable assembly (such as a CAT5CABLE/OD/25, CAT5CABLE/OD/50, CAT5CABLE/OD/75
or CAT5CABLE/OD/100 from Vecima Networks), then the process described in this document is not necessary
CAUTION
Before attaching the backshell, it is highly recommended that the user read through
this entire appendix to become familiar with all of the steps involved to ensure that
none are missed.

A1.3 Attaching the RJ45 Connector
Assembling the JMRM45S-15 Ethernet Terminating End
Step 1
Carefully cut about 1.5 inches (approximately 4 cm) of the jacket. Be careful not to cut the foil that encases
the wires. Vecima recommends that you use an exacta knife to score the length of jacket that you are
removing, then use your needle-nose pliers to carefully split the jacket. If you happen to take off all the foil,
simply remove more of the jacket. When complete, 0.65 inches (or 1.7 cm) of intact foil should be exposed
and the wires should extend another 0.85 inches (or 2.2 cm) beyond that. See Figure Figure A-4.

Step 2
Untwist the wire pairs and separate them. Fold the stranded wire back over the foil. See Figure A-5 below
for a picture of wires prepared for insertion into the connector sleeve.
Figure A-5 Preparing the wires for insertion in connector sleeve
Step 3
Insert each wire through the loading sleeve in the precise order shown in Figure A-6. Ensure that the foil is
closed around the wires and that the loading sleeve is pushed as far back on the cable as possible so that
it is close to the foil. Be sure to insert the wires into the open end of the loading sleeve. Trim the wires so
that the they extend from the foil by 0.4 inches (1 cm). Figure Figure A-7 shows the completed assembly
before crimping.

Step 4
Before installing into the connector bend back the metal strain relief along the cable length. The metal strain
relief should fit just after the jacket and cover the foil.
Check the following before crimping:
1) The wires are in the correct order. See Figure A-6
2) You can see the copper ends of the wires. If the wires are not snug against the connector end, the
connection will be intermittent.
After ensuring that the cable is prepared correctly, crimp the cable using a WT1144 or WT1145 crimping
tool as shown in Figure A-8. The crimped cable is shown in Figure A-9.
NOTE
If no crimping tool is available, use a pair of pliers to crimp the shield to the cable.
Ensure that the shield is securely attached to the cable.

Appendix
B1 Installing the Antenna - Points to Consider
Improperly installed antennas will add cost, time, and frustration to your operation. Taking some time to plan a proper
installation will have long term benefits.
B1.1 Planning the Installation
Consider the following points when planning an installation:
•
The antenna should support proper grounding and lightning protection.
It is usually far easier to bring the coax into the building where the AC power enters the building; because this is the
easiest and cheapest way to properly bond the cable entrance to the AC ground (coax is easier and cheaper to work
with than #6 AWG copper). Any lightning energy coming in on the coax will be also shared and spread over to the
AC ground system, and there will be no voltage differential between the two ground systems.
•
The antenna should be able to send and receive a strong signal.
The simplest method is to presurvey the proposed location with an antenna and transceiver that are connected via
a temporary string of coaxial cable to a power inserter. The assembly can be mounted to any pole and hand–held
to determine the presence of signal using the integrated beeper.
•
The antenna should support your plan for cableruns.
Cableruns that are too long might decrease the efficiency of signal transmission. Cableruns should be able to
support proper grounding and surge protection. Make sure that you have determined the entire wiring route & needs
before drilling holes in the structure and attaching mounting hardware.
CAUTION
To comply with RF exposure requirements, the integrated antenna or any external antenna which is
connected to an OBR3650HP requires a minimum distance of 1.5 meters between it and all persons.
B1.2 Safety Considerations
Before you begin your installation, read all critical safety warnings.
•
Do not put the antenna under a power line. The power line can cause interference, and also exposes the Installation
to unnecessary site hazards.
•
All Installations must meet building and electrical codes. Note that some municipalities have restrictions or
community covenants regarding towers and antenna structures. Check first.
•
Do not install the antenna in high winds or in stormy weather, particularly if lightning is present.
•
Remember to assemble the antenna hardware at a safe location before climbing up to the antenna mount.
•
Depending on your location, you may need two or more people to install the antenna and mount.
B1.3 Evaluating the Mounting Location
You can mount the antenna to a variety of surfaces.
•
The antenna should have a clear line-of-sight to the subscriber station. Do not put the antenna where it will be
blocked by people, animals or vehicles.
Consider how time and the season will affect the line-of-sight. For example, will foliage from growing trees interfere
with the line-of-sight? Will wind or ice add strain to the mounting assembly?

•
The simple arm supplied with the integrated antenna assembly can be mounted to the side of the house if you can
locate the structural studding.
The simple arm can also be attached to brick or cinder blocks. If mounting to brick, be sure to put the anchors in the
brick only, as anchors will not hold in joint mortar. If mounting to cinder blocks, use toggle bolts that go into the hollow
space in the block.
•
The rooftop will often be another spot to fasten to. This usually is the best location for obstruction clearance. Locating
underlying truss structure can be done with stud finders, looking for nail fasteners through the fascia board, standard
sounding techniques, or from the underside of the roof. To prevent the roof from leaking, you should caulk the holes
with silicone sealant around the holes and at the bottom of the antenna foot where it contacts the surface. Apply the
sealant before you bolt the foot down tight. Be sure to caulk all holes to prevent leaks.
•
An independent radio tower can also be used, but the Installation of these towers is beyond the scope of this
document, usually involving professional structural engineering. Metal towers can provide some of the best lightning
protection since the large metallic structural elements will best carry lightning energy straight to ground.
•
Wooden poles are NOT recommended, because the insulating properties of the wooden pole mean that a large
percentage of a lightning stroke will follow the coax towards the terminal end, even when substantial grounding
conductors are used. Also, wooden poles will sway in the wind putting the antenna beam in and out of alignment in
high wind conditions. By the time the pole is re-guyed to minimize the sway; a properly engineered metal tower could
have been installed.
•
Wind considerations. The integrated antenna has been engineered to operate in 160 Km (100MPH) winds, and
survive in 220 Km (135 MPH) winds, but these forces will generate several hundred Kg. of load to the supporting
mast. At this point, the mounting structure needs to be very secure.
•
The Installation should be accessible year round. Ice might build up in the winter or early spring time.
TIP
When the primary coaxial cable is placed, leave approximately 24” of coaxial cable with a 4” to 6” diameter loop
where the antenna will be installed. This will allow for the required flexibility for adjustment and future servicing.
