BreezeACCESS MMDS Series 1 SU-I/ID Installation Manual

1. INTRODUCTION

This manual describes installation guidelines for BreezeACCESS/MMDS SU-I

and SU-ID Subscriber Units.

The BreezeACCESS IP Broadband Wireless Local Loop (WLL) system allows

access service providers to provide high-speed IP connectivity services to their

subscribers. To support IP-based services effectively BreezeACCESS systems

employ wireless packet data switching technology.

The BreezeACCESS MMDS line of products uses Frequency Hopping Spread

Spectrum radios that operate in Time Duplex Division (TDD) mode in the

2.500GHz – 2.686GHz frequency range.

The SU-I/ID-MMDS line of Subscriber Units comprises compact units that are

designed for indoor installation. SU-I units include two 2dBi integrated antennas.

SU-ID units have two RF connectors for detached diversity antennas. Detached

antennas can be installed either indoors or outdoors, depending on the specific

site conditions.

The SU-I/ID-MMDS is available in two frequency bands:

• SU-I/ID-MMDSa products operate in the 2.500 - 2.600 GHz frequency band.

• SU-I/ID-MMDSb products operate in the 2.596 - 2.686 GHz frequency band.

The SU-I/ID-MMDS series includes the following products:

• SU-I/ID-1D-MMDSa/b: supports a single Ethernet device

• SU-I/ID-8D-MMDSa/b: supports up to eight Ethernet workstations/PCs

• SU-I/ID-BD-MMDSa/b: supports a LAN (a bridge functionality)

Note: The information contained in this manual is applicable to

BreezeACCESS MMDS units with software release 2.5.

BreezeACCESS/MMDS Series 3 SU-I/ID Installation Manual

2.3 Installation Overview

Standard installation involves the following steps:

1. Verify that all components of the packing list, described in Section 2.1, are

intact and verify availability of the required items listed in Section 2.2.

2. Install the unit and antenna(s) in optimal locations as described in

Section 2.4.

3. Connect the antenna(s) to the unit as described in Section 2.6.(SU-ID units)

4. Connect the power supply to the unit as described in Section 2.7.

5. Connect the Ethernet port to the unit as described in Section 2.7.

7. Align the antenna(s) for optimal connectivity and configure the Maximum

Data Rate if applicable, as described in Chapters 4 and 5.

8. Check the functionality of the unit as described in Chapter 6.

2.4 Installation Guidelines

This section describes the installation guidelines and the various considerations

that must be taken into account when planning the installation.

2.4.1 Location of the Unit and Antenna(s)

• The unit can be placed on a shelf, or can be attached to the ceiling or a wall

using a mounting bracket. SU-ID units should be installed as near to the

antenna(s) as possible to minimize loss of RF power in the cable(s).

• Keep the units well away from sources of heat, such as radiators, air-

conditioners, etc.

Basic Installation

SU-I/ID Installation Manual 4 BreezeACCESS MMDS Series

• For most applications, the most convenient choice is to use SU-I units,

equipped with two integral 3dBi omni antennas.

2.4.2 Location of the Antenna(s)

• Any physical object in the path between two units can cause signal

attenuation. Common obstructions are buildings and trees. If a unit’s

antenna is installed indoors, the walls and/or windows between the two

sites are physical obstructions. If the antenna is positioned outdoors, any

buildings or other physical structure such as trees, mountains or other

natural geographic features higher than the antenna and situated in the path

between the two sites can constitute obstructions.

• Install indoor antennas as close as possible to a window (or wall if a

window is not accessible) facing the required direction. Avoid metal

obstacles such as metal window frames or metal film anti-glare windows in

the transmission path. Install outdoor antennas high enough to avoid any

obstacles, which may block the signal.

• Position the antennas clear of metal furniture and away from moving metal

objects such as metal fans or doors.

• For best performance, position the antennas clear of radiation sources that

emit in the 2.5 - 2.7 GHz frequency band, such as microwave ovens.

2.4.3 Antenna Diversity

In applications where no multipath propagation is expected, a single antenna is

sufficient to ensure good performance levels. However, in cases where multipath

propagation exists, BreezeCOM recommends that two antennas be used. This

takes advantage of space diversity capabilities. By using two antennas per unit,

the system can select the best antenna on a per-packet basis (every several

milliseconds).

Multipath propagation is to be expected when there are potential reflectors

between the Access Unit and Subscriber Units. These reflectors may be buildings

or moving objects such as airplanes and motor vehicles. If this is the case, the

radio signal does not travel in a straight line, but is reflected or deflected off of

the object, creating multiple propagation paths.

Basic Installation

BreezeACCESS/MMDS Series 5 SU-I/ID Installation Manual

When installing a single antenna, modify the transmit diversity option to either

antenna 1 or antenna 2, according to the antenna being used.

2.4.4 Antenna Polarization

Antenna polarization must be the same at either end of the link. In most

applications, the preferred orientation is vertical polarization. Above-ground

propagation of the signal is better when it is polarized vertically. To verify

antenna polarization, refer to the assembly instructions supplied with the antenna

set. For screw-on and detached omni antennas, make sure that the antennas are

extended upward vertically in relation to the floor to achieve vertical

polarization.

2.4.5 Antenna Seal

When using outdoor antennas, you must seal the antenna connectors against rain.

Otherwise the antennas are not suitable for use in outdoor installations.

2.4.6 Lightning Protection

Lightning protection is designed to protect people, property and equipment by

providing a path to ground for the lightning’s energy. The lightning arrestor

diverts the strike energy to ground through a deliberate and controlled path

instead of allowing it to choose a random path. Lightning protection for a

building is more forgiving than protection of electronic devices. A building can

withstand up to 100,000 volts, but electronic equipment may be damaged by just

a few volts.

Lightning protection entails connecting an antenna discharge unit (also called an

arrestor) to each cable as close as possible to the point where it enters the

building. It also entails proper grounding of the arrestors and of the antenna mast

(if the antenna is connected to one).

The lightning arrestor should be installed and grounded at the point where the

cable enters the building. The arrestor is connected to the unit at one end and to

the antenna at the other end.

Basic Installation

SU-I/ID Installation Manual 6 BreezeACCESS MMDS Series

The professional installer you choose must be knowledgeable about lightning

protection. The installer must install the lightning protector in a way that

maximizes lightning protection. BreezeCOM offers the following high-quality

lightning arrestor assembly:

BreezeACCESS AL 1 Lightning Arrestor - Part No. 872905 5 ft (1.5m), “N”

Male to “N” Female.

Note: Detached antennas, whether installed indoors or out, should be installed

ONLY by experienced antenna installation professionals who are familiar

with local building and safety codes and, wherever applicable, are licensed

by the appropriate government regulatory authorities.

Failure to do so may void the BreezeACCESS Product Warranty and may

expose the end user to legal and financial liabilities. BreezeCOM and its

resellers or distributors are not liable for injury, damage or violation of

government regulations associated with the installation of detached

antennas.

2.5 Wall Mounting the Unit

Aligning the Antenna

BreezeACCESS/MMDS Series 15 SU-I/ID Installation Manual

4. ALIGNING THE ANTENNA

Omni and low gain antennas do not require alignment due to their wide radiation

pattern. High gain antennas have a narrow beamwidth, necessitating an

alignment procedure in order to optimize the link.

For Subscriber Units with directional antenna(s), you can either use the LED

indicators on the front panel of the unit or view the Received Signal Strength

Indication (RSSI) on the monitor. In most installations, alignment using the

LEDs is sufficient. The RSSI reading can be used when finer alignment is

required.

Note: Antenna alignment of the Subscriber Unit is possible only after the Access

Unit you wish to associate with is operational and the ESSID was properly

configured.

4.1 Aligning the Antenna Using the LEDs

1. Synchronize the units by aligning the antenna manually to point to the base

station until the WLNK indicator LED on the front panel of the unit

illuminates.

2. Rotate the antenna left and/or right until you reach the point of signal quality

reading on the quality (QLT) LEDs. The higher the number of illuminated

LEDs the better is the quality of the link. Make sure that at all times, the

front of the antenna faces the general direction of the Access Unit.

3. For proper operation, at least one (L) LED should be illuminated. If this is

not possible, improve the link quality by placing the antenna at a higher

point or in a different location.

4. After the antenna is optimally aligned, tighten the U-bolts (or metal band) to

secure the antenna to the pole.

Aligning the Antenna

SU-I/ID Installation Manual 16 BreezeACCESS MMDS Series

4.2 Aligning the Antenna Using the Site Survey Menu

1. Start the Monitor program as described in Section 3.1.

2. From the main menu, type 4 to access the Site Survey menu. Type 4 to start

the Continuous RSSI Display. Each line in the display includes the number

of frames that were received since the last measurement (total Rx) and the

average RSSI for these frames.

3. Rotate the antenna left and/or right until you reach the point of maximum

RSSI reading. Make sure that at all times, the front of the antenna faces the

general direction of the Base Station.

4. For proper operation, the RSSI reading should be at least 52 units. When the

maximum reading is less than 52 units, try to improve it by placing the

antenna at a higher point or in a different location. For best performance it is

recommended that the RSSI be higher than 76.

5. Press the Esc key to stop the test.

6. Tighten the U-bolts (or metal band) over the antenna to secure it to the pole.

Maximum Data Rate Configuration

BreezeACCESS/MMDS Series 17 SU-I/ID Installation Manual

5. MAXIMUM DATA RATE CONFIGURATION

1. If the average RSSI reading using the Average RSSI Continuous Display is

lower than 76, the default data rate of 3 Mbps is too high and the data rate of

the unit should be configured accordingly:

2. From the main menu, type 3 to access the Basic Configuration menu. Type 5

to access the Maximum Data Rate menu.

L Type 3 (3Mbps) if the RSSI reading is higher than 76 units.

LL Type 2 (2Mbps) if the RSSI reading is between 66 to 76 units.

LLL Type 1 (1Mbps) if the RSSI reading is lower than 66 units.

3. Reset the unit for the new configuration to become effective.

APPENDIX A. AL 1 Lightning Arrestor

The AL 1 Lightning Arrestor is used to protect transmitters and receivers from

transients originating from lightning or EMP.

The AL 1 is gas tube-based and is not radioactive. The gas discharge tube can

sustain several transients if the time period between transients is sufficient to

allow the tube to cool down.

APPENDIX B. USING TELNET

Use the following procedure to connect to BreezeACCESS units via a Telnet

session.

1. Connect the PC to the Ethernet port of the unit (or the hub to which the unit

is connected) using a straight Ethernet cable. If you connect the PC directly

to a unit that is normally connected to a hub, use a crossed Ethernet cable.

You may also connect the PC to any Ethernet port on the network and

communicate with the unit to be managed via the wired or wireless media.

2. Make sure that the IP parameters of the PC are configured to enable

connectivity with the unit.

3. Run a Telnet application and use the IP address of the unit to be managed as

the Host Name.

4. Set Port to Telnet (this is the default).

5. Set Terminal Type to VT100 (this is the default).

6. Enter the Service Provider password.

7. When the password is recognized, the following message is displayed:

You have entered.

8. Press Enter, the Breeze ACCESS Monitor is displayed on the screen.

To exit the Telnet session, choose Disconnect from the Connect menu.

(The session is terminated automatically, after a specific time of inactivity

determined by the Log-out Timer).
