1.2 REGULATORY

1.2.1 Maximum Permissible Exposure Limits

DO NOT TRANSMIT with this base station and antenna when persons are within the MAXIMUM
PERMISSIBLE EXPOSURE (MPE) Radius of the antenna. The MPE Radius is the minimum distance
from the antenna axis that ALL persons should maintain in order to avoid RF exposure higher than the
allowable MPE level set by the FCC.

FAILURE TO OBSERVE THESE LIMITS MAY ALLOW ALL PERSONS WITHIN
THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION, WHICH
EXCEEDS THE FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT. IT IS
THE RESPONSIBILITY OF THE BASE STATION LICENSEE TO ENSURE THAT
THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT ALL
TIMES DURING BASE STATION TRANSMISSION. THE BASE STATION
LICENSEE IS TO ENSURE THAT NO BYSTANDERS ARE WITHIN THE RADIUS
LIMITS.

1.2.2 Determining MPE Radius

THE MAXIMUM PERMISSIBLE EXPOSURE RADIUS is unique for each site and is determined
based on the complete installation environment (i.e. co-location, antenna type, transmit power level, etc.).
Determination of the MPE distance is the responsibility of the VIDA

the system can be seen as extending the enterprise WAN to remote locations using the licensed 4.9 GHz
public safety band. Some common applications for this system include:

• Remote surveillance video

• Mobile

• Connection of remote precincts to the enterprise and/or VIDA network

• Backhaul of IP based LMR traffic

4.4 VIDA

The basic architecture of the 4.9 GHz VIDA
consists of one or more base station(s) and at least one client (
of client devices; fixed and mobile. Fixed client devices are usually mounted outdoors with directional
antennas and have a range of up to 10 miles. Mobile clients are vehicle mounted and use an omni­directional antenna. The range of a mobile client to base station is a few hundred meters.

system

The base station implements the 802.16-2004 protocol in a 5 MHz channel, delivering an over-the-air
throughput from 4 to 19 Mbps. All communication over this channel is scheduled by the base station,
with contention slots provided for subscriber stations to request bandwidth. This coordinated scheduling
feature of the protocol provides significant advantages such as:

• Minimizes contention between clients

• Maximizes channel utilization

• Maximizes ability to coordinate frequency usage among users

• Enables guaranteed bandwidth services for critical multimedia applications.

The use of a scheduling protocol also makes the network more resilient to simple denial of service attacks

requirements. Depending on the location and site planning, a directional antenna can significantly extend
the effective coverage area of the base station. For example, one can choose a high gain directional
antenna to effectively cover a long strip of highway, in the meantime avoiding the area further away from
the highway (where coverage is no longer needed) to reduce the total number of base stations. Another
example could be using a 90-degree sectional antenna to effectively cover a town-center area while
avoiding rural regions where no coverage is required. The user can directly mount an omni-directional
antenna to base station RF antenna port. Additionally, four mounting holes are provided on the VIDA
Base Station chassis to allow a directional antenna to be mounted on an optional bracket. Finally, the user
can choose other industry means for mounting a directional or omni-directional antenna separate from
base station. In this case, however, the total length of cable should not exceed 5 feet. Choose high
quality 50-Ohm cable with the lowest loss at 5 GHz.

MM-009804-001

Before installing the VIDA
selection before attempting to install the base station. Since high frequencies do not readily pass through
trees or buildings, consideration should be given to the following:

• Ensure there are no obstructions (such as buildings or trees) in the radio path between base station

and fixed client units

• Ensure the any future building construction or tree growth will not obstruct the radio path

• Ensure there is sufficient clearance around the Fresnel Zone so there is minimal interference from

obstacles along the radio propagation path

• Ensure the installation adheres to any local building codes and permits

• Ensure sufficient electrical power is available at the installation site

• When using directional antennas, align the base station antenna to maximize the received signal

strength indication (RSSI)

• Ensure area around an omni-directional antenna is clear (at least 30 inches) so as not to distort the

RF pattern

• Locate the base station away from any sources of interference that could degrade the performance

of the base station

MAX

Base Station, the System Engineer and installer should plan the site

• Ensure the base station and fixed clients are within maximum coverage range of reception

• Maximum standard CAT-5 cable length connecting the base station to the Ethernet LAN is 100

meters and maximum antenna cable length is 5-feet

conditions. The user can choose different antenna types (omni-directional or directional) depending on
the application. It is preferred that the user specifies 50-Ohm low loss (@5GHz) cable with minimum
length (5-feet maximum) between the antenna connector and antenna port on the base station to avoid
further loss of RF power.

The base station is available as either as +24 VDC (hardened) or 110 VAC version. The total power
consumption is less than 60 Watts.

For the AC version, the radio uses weatherproof RJ-45 for connector as data and network connections.

9.1.2 Transmit Power Level Calibration

The power level calibration is performed at CH1, CH5, CH10 (lowest, middle, and highest) to ensure the
over-band performance. An Agilent PSA E4440A under spectrum emission mask mode is used to
perform the calibration. A standard baseband OFDM QPSK 3/4 Signal (Downlink Burst, 50% duty, 10
msec. frame) is used for the calibration. The on board 30 dB/ 1 dB step attenuator is used to adjust power
level. The cable loss (radio antenna port to PSA input) is calibrated out so the PSA can measure channel
power at the antenna port. After the TX power level calibration step, the FCC emission mask is used to
check TX spectrum at CH1, CH5 and CH10 to ensure the compliance. After calibration, the base station
uses the calibrated TX power as a default value to initialize the radio.

11 CABLE FABRICATION

11.1 ETHERNET CABLE PLUG KIT

For the AC version of the base station, the Ethernet cable connected to the base station uses a RJ-45
connector protected by an Industrial Circular Ethernet plug assembly that protects the RJ-45 connector
from the elements.

MM-009804-001

The Stranded Wire Plug Kit (Tyco Electronics # 1738607-2), shown in
8-position Category 5e RJ-45 plug, load bar, and plug assembly. The load bar is used to hold the cable
wires for insertion into the RJ-45 plug. The RJ-45 plug must be terminated and then installed into the
plug assembly. The RJ-45 plug is held in the plug assembly by the locking tab. The cable fitting holds
the RJ-45 plug in the plug assembly and seals the plug at the cable end. When engaged, the connectors
are held together by a locking mechanism (coupling ring and bayonet lock), which prevents accidental
disconnection. The engaged connectors are sealed by the interfacial seal.

Cable Selection

The RJ-45 plug will accept Category 5e, 100–ohm unshielded round cable with the following
specifications:

• Cable type: 8–conductor

• Conductor size: 24 AWG

• Conductor type: 7–strand copper

• Conductor insulation diameter: 0.039 in. (0.99 cm) maximum

• Cable jacket diameter range:

RJ-45 plug accepts: 0.190 through 0.220 in. (4.83 through 5.59 cm) OD (single jacket)
Cable fitting accepts: 0.18 through 0.31 in. (4.6 through 7.9 cm) OD (double jacket)

11.1.3 Cable Preparation

Prepare the cable using the following procedure:

42

Reasonable care must be taken not to scrape or nick any part of the cable during
the stripping operation.

CAUTION

1. Slide the plug assembly (cable fitting end first) onto the cable. See Figure 11-2, Detail A.

2. Proper strip length is necessary to insert the conductors into the contact slots. The recommended strip

length is given in

Figure 11-2, Detail B.

MM-009804-001

Insulation of individual conductors must not be cut or removed. This could result in
shorted or open connections.

Figure 11-2: Cable Preparation

3. Conductor pairs must be oriented side–by–side in the order shown in

Figure 11-3, Detail A. The end

of the cable jacket must be flattened so that the conductor pairs lay side–by–side.

4. Properly sequenced conductor pairs should extend into the cable jacket to the dimension given in

Figure 11-3, Detail B, creating an oblong shape.

5. The conductor tips must be trimmed evenly to the dimension shown in Figure 11-3, Detail C. Proper

orientation of conductors must be maintained.

6. The conductor pairs must be untwisted and arranged according to EIA/TIA T568A or T568B (defined

in

Figure 11-3, Detail D). IT IS CRITICAL that the pairs are NOT untwisted inside the cable jacket.

When arranging conductor pairs, IT IS IMPORTANT that Conductor 6 be crossed over Conductors 4
and 5 as shown in

Figure 11-3, Detail C.

11.1.4 Termination

Terminate the RJ-45 plug to the cable end using the following procedure:

1. The conductors (maintaining arrangement) must be inserted into the load bar (oriented so that the

cable notch will align with the contacts) until the cable jacket rests against the cable notch. The
conductor twist must not enter the front of the load bar. The conductors must be trimmed evenly and
square with the front edge of the load bar to the dimension given in

Figure 11-4, Detail A.

Figure 11-4: Termination Requirements

45

MM-009804-001

2. The conductors must be retracted from the load bar so that the conductors protrude from the end of

the load bar to the dimension given in
deformed.

3. The load bar (oriented so that the cable notch is aligned with the contacts) must be inserted into the

RJ-45 plug until it butts against the mating feature of the RJ-45 plug, and the conductors are bottomed
on the wire circuits. The cable jacket must be against the cable notch after the load bar is fully seated.
The conductors must not be exposed between the cable jacket and cable notch. The ends of the
conductors must be clearly visible through the front of the RJ-45 plug. See

4. The RJ-45 plug must be terminated to the cable according to the instructions included with the

tooling.

Figure 11-4, Detail B. The top of the load bar must not be

If the load bar is deformed, the conductor twist entered the front of the load bar

Figure 11-4, Detail C.

If the conductors do not bottom on the wire circuits, they must be re-trimmed (after
removing the load bar/cable assembly from the RJ-45 plug), and re-inserted into the
RJ-45 plug. If the conductors are too short, the cable must be re-stripped.

11.1.5 Assembly

Assemble the RJ-45 connector into the plug assembly using the following procedures:

1. Align the locking tab of the RJ-45 plug with the wide slot at the front (end opposite the cable fitting)

of the plug assembly. See

2. Depress the locking tab, and insert the RJ-45 plug into the plug assembly. Gently pull the cable until

the RJ-45 plug is fully seated. There should be approximately 12.7 mm [.50 in.] of the RJ-45 plug
protruding from the front of the plug assembly. See

To avoid damage to the connection, the cable must be pulled GENTLY when
seating the RJ-45 plug.

CAUTION

3. While holding the RJ-45 plug in position, rotate the cable fitting as shown in Figure 11-5, Detail B

until tightened to a torque of 1.13 N–m [10 lbf–in.].

The given torque must be met in order for the cable fitting to seal the plug at the cable
end.
