Section 1

Overview

1.1 Description

Terabeam’s second generation of BRidge-In-a-Box (BRiB-II™) is a complete wireless point-to-point (P-P)

solution that bridges two LANs together using the license-free 2.4 GHz band. It consists of two 18 dBi

gain flat panel directional antennas with built-in 802.11b wireless LAN devices, and features the award-

winning industry standard TurboCell

software, a protocol which significantly enhances the performance

of outdoor 802.11b systems through the use of adaptive dynamic polling, bandwidth allocation at the

client, and packet aggregation.. The two antennas connect to the LAN’s Ethernet switches on each end

with an outdoor-rated Ethernet cable (ordered separately). The BRiB-II is ideal for connecting two office

LANs together, or for linking a WIPOP site to an Internet backbone.

The two antennas operate at 11 Mbps over-the-air, and feature the highly secure 128-bit WEP-Plus

(Wired Equivalent Privacy) encryption which, if enabled, provides extra security above standard 802.11b

WEP. The link is also transparent to VLAN tags for the most secure link. The BRiB -II will accommodate

virtually an unlimited number of client MAC addresses on each side of the link. The MAC addresses of

the LAN clients on one side appear on the other side of the link wirelessly. It is remotely configured and

managed with the Windows-based Terabeam Configurator software.

With the wireless client adapters built right into the antennas, professional antenna installation is not

required. All that is needed is to ensure that the antennas are optimally aimed and have clear line of sight

(LOS) to each other. The antennas can be mounted either vertically or horizontally polarized. Selecting

the appropriate polarization for your area will minimize or even completely eliminate interference from

other outdoor installations in the 2.4 GHz band.

Two versions of the BRiB-II are available: the standard series BRiB-II with an integral 18 dBi gain flat

panel antenna, and the BRiB-II–LR with the addition of an integrated bi-directional fixed amplifier to boost

range and improve reception. The WLAN device located in the antenna gets its power from the DC Power

Injector which puts DC power onto the Ethernet cable. Up to 300 feet of Ethernet cable (ordered

separately) between the DC injector and the antenna can be used with no signal loss.

Both the BRiB-II and the BRiB-II–LR version use a 110/220 VAC to 48 VDC power supply.

Section 2

Installation

Safety Warning

This antenna/transmitter device must be fixed-mounted on outdoor

permanent structures with a separation distance of at least 2 meters

(6.56 feet) from all persons. Users and installers must adhere to the

antenna installation instructions and transmitter operating conditions in

order to comply with the FCC’s RF exposure requirements.

CAUTION!

2.1 Locating the BRiB-II Antennas

The most important aspect of setting up the BRiB-II antennas is their location and aiming. For maximum

range (up to several miles), it must have clear, unobstructed line of site (LOS) and Fresnel Zone between

them. The BRiB-II antennas are designed to be installed outdoors. For maximum range and the

strongest signal, the two BRiB-II antennas must literally “see” each other in order to be connected. If they

do not have this clear “line of site” (LOS), you will likely not get a reliable, long-range wireless connection.

The only way to accurately determine your coverage area is to put up the BRiB-II antennas in the best

locations available and run some tests.

NOTE: It is strongly recommended that you configure and test the units prior to deploying them in the

field. Set up a “mini-network” that resembles your actual configuration as close as possible.

By using such a mock-up, troubleshooting potential problems will be much easier than if you

already installed the equipment in the field. Read through this entire Section 2 to understand

how to install the hardware.

2.2 Mounting the BRiB-II Antennas

The BRiB-II antennas can be mounted either vertically or horizontally polarized using the hardware

included with the unit. The label located on the back of the antenna contains an arrow indicating the

antenna’s polarization. Please note that both ends of the link must use the same polarization. They can

be mounted to a mast or pipe as shown in Figure 2.1.

It is very important that the Ethernet connector on the antennas be properly waterproofed. Ensure that a

high quality all-weather resistant electrical tape and/or other water sealant method, such as Permagum or

equivalent, is utilized. Silicon sealants are not recommended since they are hard to work with, do not

ensure a 100% waterproofing of the connectors and are difficult to remove, if ever necessary.

The antenna itself or the mast where it is bolted to should be connected to an Earth ground. Fig. 2.1

shows the possible grounding points that you can use.

Important: Please notice that the two units are clearly identified as side A and side B of the P-P link (see

Fig. 2.2). The two units are not interchangeable.

BRiB-II User’s Manual

Possible Grounding Points

Polarization Arrow

Figure 2.1 shows the antenna in a horizontally

polarized installation. It must be carefully

aimed at the other antenna and be mounted

with the same polarization. The housing is

sealed to prevent water build-up in the

antenna. The round connector must also be

sealed after it is plugged into the antenna. Be

sure to provide strain relief for the Ethernet

cable as well.

Horizontal polarization is generally better since

most other outdoor systems use vertical

polarization. By mounting the BRiB-II

antennas horizontally polarized, you will

minimize interference from these systems.

(Note: the two units are not interchangeable)

2.3 DC Power Injector

The Cat 5 DC Power Injector is not in a waterproof enclosure and must be protected from the weather. It

can be permanently mounted to a surface using the double stick tape found on the back of it.

2.4 Power Supply

The BRiB-II antennas come with a 110/220 VAC to 48 VDC power supply that has a standard barrel plug

[center pin positive (+) tip and outer ring negative (-)].

Ver 1.0 Page 5 March 2005

BRiB-II User’s Manual

Former BRiB-II units used a 15 VDC Power Supply. Care must be

followed not to confuse the current with the former units since this may

damage a former 15 VDC unit if a 48 VDC Power Supply is used with it.

Likewise, operating a current BRiB-II version with less than 48 VDC will

cause improper operation. Any damage caused by these actions will not

be covered by the factory warranty and will be a billable repair.

The current units have an LED label which clearly identifies them as 48

VDC units. Please see Figure 2.5 for the location of the label and

description of LEDs.

CAUTION!

2.5 Hardware Installation

Perform the following procedures for both antennas once you have determined their optimal location:

1. Use the brackets and screws to mount the flat panel antenna to a pole with a maximum diameter of

up to 1 3/4 inches.

2. Ensuring that there is no DC power applied to the cable, plug the 6-pin N-male round connector of the

outdoor Ethernet cable into the rear jack of the flat panel antenna, making sure the notch on the

connector is correctly aligned with the tab on the jack as shown on Figure 2.3. Turn the round locking

nut clockwise as you push in until it securely fastens onto the jack. Please verify that the round

connector is properly plugged into the rear jack of the antenna prior to connecting DC power

because it is possible to push it in the wrong way if enough force is used. If DC power is applied and

the connector is not properly plugged, damage to the electronics of the unit or the connector itself

may occur which will not be covered by the factory warranty.

Figure 2.3 – Plugging the Outdoor Ethernet Cable

Plug the connector into the jack by

aligning the notch with the tab

Caution: Be sure DC Power is not applied

when plugging the cable

If DC Power is applied while you are attempting to insert the round

connector into the jack, it is possible that, as you rotate the plug in an

effort to find the key, DC power pins will momentarily touch the Ethernet

pins. If this happens the Ethernet circuitry on the board will be

damaged. Also, do not apply excessive pressure when you insert the

round connector or the pins will pop out. Any damage caused by this

action will not be covered by the factory warranty and will be a billable

repair.

CAUTION!

3. Attach the other end of the outdoor Ethernet cable to the Cat 5 DC Power Injector at port RJ-45

labeled “To Antenna.”

4. Connect the Ethernet cable labeled “To PC/Router” from the Cat 5 DC Power Injector into a regular

port on your router, switch or hub. If you connect to a laptop or PC, use a cross-over cable or adapter.

5. Perform an Earth ground connection to any of the rear bolts of the unit, the mounting brackets, or the

mast (if metallic) (refer to Fig. 2.1). For maximum protection, also connect the metal wire of the surge

protected DC Injector to ground as shown on Figure 2.4.

6. Connect the barrel plug of the power supply to the “DC Power” jack on the Cat 5 DC Power Injector,

then plug the Power Supply into an AC outlet. Check that the Power LED turns on. If there is traffic

over the wireless medium the Wireless Link LED should be flashing. If the Ethernet port is active the

Ethernet Link LED should be flashing. Radio Status should be off, it turns on only when there is a

malfunction of the internal card (refer to Fig. 2.5). Also, a water-proof plug is located next to the LED

label. You may remove this plug to gain acces to a reset push button inside the BRiB-II for disaster

recovery, or if so instructed by your Terabeam support representative during troubleshooting or

technical assistance.

7. Configure the BRiB-II using the Configurator software. Please refer to the Marquee Series

Configuration Guide, available as a pdf file on your CD ROM. Also, an online help is available by

pressing F1 or clicking Help-> Index from the main screen.
