FCC Maximum Permissible Exposure Guidelines
In 1996. the FCC adopted new guidelines for evaluating environmental effects of RF emissions. The
set limits for Maximum Permissible Exposure (MPE) to RF energy in the 2.4 GHz band, where the
RadioWire Modem operates, is set at 5 mW/cm2 tor Occupational/Controlled Exposures and
1 mW/cm2 for General Population/Uncontrolled Exposure. Occupational/Controlled limits apply in
situations where persons are exposed as a consequence of their employment. provided that those
persons are fully aware of the potential for exposure and can exercise control of their exposure.
Uncontrolled Exposure applies to situations where the general public may be exposed and may not
be fully aware of the potential tor exposure or can not exercise control over their exposure.
The RadioWire Modem (RWM) should be installed by a competent technical person who understands
the potential for exposure and can exercise properjudgement during the installation of this product,
Radio Connect Corporation (RCC) recommends that the RWM be installed in a location where
members of the general population cannot walk into the direct RF path or touch the antenna. This is
necessary both to ensure a reliable connection and to avoid unnecessary exposure to RF emissions.
DRAFT ii
or" e _ ...w_ .,,_
Wireless Internet Sen/ice Link - User's Manual
RCC recommends that the installation of the RadioWire Equipment is done with the equipment all to
eliminate the risk ol unnecessary exposure to RF energy. When tine tuning the direction of the
antenna, keep your HP exposure time to a minimum if you need to place hands or other body pans in
locations listed in the special cases below. Normal installation of this product is possible without
exposure to RF levels in excess of MPE limits for Controlled Exposure.
With installation per RCC recommendations, the RadioWire Modern does not generate power density
levels in excess of the MPE Limits lor General Population/Uncontrolled Exposure. Be aware of the
situations where the limits for Occupational/Controlled Exposures are approached or exceeded.
These are:
> Maximum Permrssible Exposure (MPE) limits for Uncontrolled Exposure is exceeded for
distances closer than 22.4 cm (9 inches) from the helical antenna within the 35° beamwidth.
> MPE limits for Controlled Exposure is exceeded lor distances closer than 10 cm (4 inches) from
the helical antenna within the 35° beamwidth.
‘r MPE limits tor Controlled Exposure can be exceeded in the area between the reflecting surface of
both the 0.6m and 1m dish and the actively radiating antenna.
; For the 0.6 meter dish. the MPE limits for Uncontrolled Exposure is exceeded on the reflecting
surface of the dish.
As noted above, RCC recommends that this equipment be installed so these situations are not
generally possible,

2.1 .2 Antenna
Figures 2-3 through 2-5 provide details of the three antenna types available with the RWM.
It is not necessary to use the same type ot antenna at the two ends of a link. The actual
combination depends on the range required. Table 2-1 shows the range capabilities of each
possible combination in free space conditions, assuming that a link margin of at least 25 dB
is ore-requisite. Note that the upper limit of 20 miles is governed by protocol constraints,
and not by the antenna gain.

2.1 .3 Mounting Bracket
RadioConnect antenna mounting brackets are designed to allow tilting in the vertical plane,
to accommodate elevation differences between the RWM units at the two ends of a link.
This capability is especially useful for relatively short links. The brackets are calibrated with
tilt angles above and below horizontal. Once the RadioWire Modems have been installed
and aligned with each other, and the brackets firmly locked in their optimum positions, you
should record the tilt angles read from the mounting brackets, in your Configuration
Worksheet.
2.1 .4 RWM-to-NIM Cable
The cable that runs between the roof-mounted RWM and the
in-building NIM is a special serial cable that carries low
voltage power up to the FlWM, as well as carrying data
between the units. This cable is offered in standard lengths
from 25 feet to 200 feet, and in two different fire-resistance
ratings - standard or plenum-rated. Custom lengths are also
available to special order. Check that the lengths of the
cables you receive match your order, and if there is any
discrepancy, notify your reseller as soon as possible.
The standard PVC cable is satisfactory tor use in vertical wall
cavities and shafts, while plenum-rated cable is required for
routing through under-floor plenum space. In either case, the Fiflsnlor
cable is supplied as a kit, with the connector not installed at zszgg'jzs
one end in order to facilitate feeding the cable between the connector

Figure 2-7 shows the NIM front panel layout The liquid crystal display (LCD) at the right
side of the panel displays ongoing status information, and is updated automatically at
1-second intervals.
At the left side of the panel, six light emitting diodes (LEDs) serve as signal indicators:
- USER An active connection exists between the NIM and the user‘s
{Green LED) equipment. For the serial NIM, this implies that the cable
between the NIM and the user’s equipment is installed, and
that the DTR (Data Terminal Ready) signal is asserted. For
the Ethernet NIM, the LED indicates that an active Ethernet
cable is connected to the NIM.
- CL For the serial NIM, this LED indicates that the NIM clocking
{Pied LED) signal is present. This is the signal that enables synchronous
transmission to occur. For the Ethernet NIM, this LED flashes
whenever a collision is detected.
- TX This LED is on whenever the user‘s equipment is transmitting
(Yellow) data to the NIM.
- FtX This LED is on whenever the NIM is forwarding the data it has
{Ye/low) received from the FtWM, to the user's equipment.
- AFlQ The ARC LED flashes at the receiving end of a link when a
(Red) packet error is detected.
- LCK This LED has a dual function. It flashes red while the
(Red/Green) RadioWire modems at the two ends of the link are attempting
to synchronize with one another. Once synchronized, the LED
changes to a solid green display, indicating that the two ends
are locked.
For initial configuration or reconfiguration of the WlSL system, the front panel of the NIM
unit may be removed to provide access to the Console port. The port comprises a female
DE-9 connector, to which either a PC-compatible computer or a dumb terminal may be
attached. The cable required is a 9-pin straight—through male-to-temale serial cable. A
6—fool cable of this type is included in the System Installation Kit available separately from
FtadioConnect (part number 004-0001-00). Such cables are also readily available at most
computer stores.

2.2.3 Synchronization Cable
One synchronization cable is provrded with each WISL system. This 12“ cable is used to
connect two NlM units together via the sync ports (FtJ-H connectors) on the rear panel. More
than two NIMs may be interconnected by daisy-chaining them together, as shown in
Figure 2-8. Note that the two connectors on each unit are functional y identical, so that
either cable may be plugged into either socket.
Figure 2-8. NIM Units Daisy-Chained' tor Synchronlzation
The purpose ol interconnecting units in this way is to provide a clock signal between them
that causes all units to synchronize their transmit and receive cycles. The clock signal is
provrded by a single NIM configured as the ‘primary' unit. The effect at this interconnection
is that all units transmit in the same cycle, and then receive in the same cycle, which avoids
the possibility of some of the co»located units receiving the transmissions of others.
Wireless Internet Service Link - Users Manual Section 4: Operation
3 Installation
CAUTION
It you are not familiar with working on towers and antennas,
get help from an experienced installer. Installing tower
structures and mounting antennas can be dangerous and
lite threatening. Make sure the lower or pole you are using
is at appropriate size to carry the weight and wind load of
the RadioWire Modern and antenna system.
3.1 System Installation Kit
RadioConnect offers a System installation Kit (part number 004-0001-00) which may be
purchased separately from your WISL systems. Although not pre-requisite for installing a
link, the kit is recommended. It is re-usable for installing multiple links, and contains the
following items:
- 3-foot FtWM-to‘NlM cable. required if units are to be configured prior to installation
- 6-foot Console cable
- FlF emulation cable
- Cable pull grip
- Cable assembly/continuity tester lor FlWM-to~NlM cable (comprises 2 components
— loop-back terminator for RWM end of cable, and display terminator for NIM end.)
- Tools: Allen key, screwdriver and wrench
- Magnetic compass
In addition to these items, the person installing the link may also need a steel-tape cable
puller (also referred to as a "snake"), and some nylon cable ties, A cable tie will be used to
attach the cable pull grip to the cable puller, as explained in Section 3.6.1 below,
3.2 Installation Procedure
Figure 3-1 shows a high level flowchart of the required and optional steps tor installing a
link, The WISL equipment can be installed without requiring initial configuration. However,
this is not recommended, as it is much easier to configure and test both units together at a
single location, before they are transferred to their eventual (remote) sites.
In either case, at least one configuration parameter must be set before the two WISL
systems can communicate That parameter is the ‘Master/Slave Status’ (Section 3.4.3). Until
one end of the link is set as Master, and the other end as Slave, installed units cannot be
aligned.

3.3 Configuring Your System
The first step towards configuring each of yourWlSL systems is to complete the link
Configuration Worksheet (Appendix C). Refer to the System Overview and Planning Manual
(part number 950-0001-00) for guidance in preparing the Worksheet There are several
important parameters that must be configured correctly for proper operation:
1) Pseudovrandom spreading code
2) Frequency channel
3) Master/Slave status
4) Synchronization generator status
5) Transmit power control mode and level
Each of these parameters is discussed in detail below, and a completed Worksheet example
is shown in Figure 3—8.
Next, take the following steps in preparation for configuring each unit:
- If the configuration process is being carried out before a WISL system has been
installed. connect the RWM and NIM together using the 3-foot cable provided in the
System Installation Kit.
- If the configuration process is being carried out after installation, the FlWM and NIM are
already connected.
- Connect a personal computer (PC) to the MM console port (section 2.22) using a
standard serial cable (9-pin, straight through, male-to-female). One such cable is
provided in the System Installation kit.
- Power up the PC and install the Configuration Utility from the 2—disk set provided with
your WISL system. The PC must be running Windows 95 or later, or Windows NT.
Insert disk 1 into the floppy drive, and display its contents under Windows Explorer,

3.4 Radio Configuration Parameters
3.4.1 Frequency Channel
The RadioWire Modem supports three discrete, non-overlapping frequency channels within
the 2.4 GHz band allocated for unlicensed use. These are shown in the Configuration
Worksheet as channels 1, 3 and 5. The other two channels (2 and 4) partially overlap their
neighbors. In general, use channels 1, 3 or 5 only, unless you are co-Iocating more than
three RWM units at the same site. Select the desired channel from the pull—down menu.
3.4.2 Master/Slave Status
One unit on each point-to-point link must be configured as the link Master. The other unit
must be the link Slave. The link Master controls transmit and receive timing for a given link.
When multiple RWM units are co-Iocated, they will typically all be specified as Masters
(Figure 3-5). However, it a hierarchical network is being built, similar to that shown in
Figure 3-6, all nodes except the central one will have at least one Slave coupled to one or
more subsidiary Masters through appropriate user equipment such as an Ethernet nub or a
serial synchronous time-division multiplexer (TDM). Click on the appropriate button to select
Master or Slave status.
All central units
are ‘Masters’

3-5 DRAFT
Wireless Internet Service Link - User's Manual Section 4: Operation
All central unlts
are ‘Masters’
Figure 3-6. Master/Slave Assignments in a Hierarchical Network
3.4.3 Synchronization Generator
When multiple RWMs are co-Iocated at a site, they must be synchronized to all transmit at
the same time and all receive at the same time, to help avoid mutual interference. To
accomplish this, every RWM is equipped with the ability to generate a synchronous clock
signal. However, only one unit can be the active synchronization generator at any given
time, and all other co-Iocated units must receive the synchronization signal through the
‘daisy—chain‘ oi cables that couple their NIMs together.
A special requirement applies at all subsidiary nodes of a hierarchical network. At all such
nodes, p_nly Slave units may take the role of synchronization generators. This is because a
Slave unit derives its clock from the airvvave signal it receives from its associated Master.
This requirement ensures that the entire network operates coherently from a single clock
source. The example in Figure 3-7 illustrates this. Click on Sync Generator, if required.
3.4.4 Transmit Power Level
The transmit power level may be set between a minimum at -2dB and a maximum of +24dB
When shipped, the default setting is odB. it a unit is being configured prior to installation,
care should be taken with regard to increasing the power level. Excessive power levels can
be hazardous to humans, as well as to other operating radio equipment in the near vicinity.
it possible, setting of the power level should be left until the link is being installed. In the
U.S.A., the maximum power level oi +24dB is only required when operating at the maximum
range specified for the antennas. Some countries require a lower maximum transmit power
level than the +24dB permitted in the U.S.A.

3.4.5 Pseudo-Random Spreading Code
There are more than 16,000 possible pseudo—random spreading codes available to ensure
the privacy of RadioWire links, and which contribute towards the extraordinary interference
rejection characteristics of RWM units. The same value must be configured for both ends of
a link. If multiple links are to be installed, select a different code for each link.
Many RWMs can share the same frequency channel with negligible interference when a
different pseudo-random code is selected for each different link.
3.5 NIM Configuration Parameters
3.5.1 Type
By default, this field will display the type of NIM being configured - Serial or Ethernet - and
may not be altered.
3.5.2 Clock Polarity (Serial only)
This parameter must match the clock polarity of the equipment attached to the NIM. The
default setting is ‘Normal‘. If necessary, click on 'Inverted'.
3.5.3 User Mode (Serial only)
The connector on the Serial NIM for attachment of user equipment is a female DB-25.
However, the User Mode parameter allows you to select the active signal interface on the
connector. The choices available on the pull-down menu are v.35, ElA-530, ElA-530A or

Caution: Only select the setting that matches the signal intertace of the attached
user equipment, If this caution is not observed, electrical damage may result to
either the user's equipment or the NIM.

3.6 Pre-lnstallation Testing
To ensure satisfactory operation between two WISL systems, they may be tested together
before being transferred to their eventual destinations. For testing in close proximity, the RF
emulation cable supplied in the System Installation kit must be used.
CAUTION
Do not under any circumstances attempt to test two
RadioWire Modems in close proximity, with their
antennas installed. To do so may result in severe
damage to both units, due to excessive signal load
on the receivers.
- Two units equipped with +14dBI helical
antennas may not work satisfactorily at any
distance less than 130 meters.
Two units equipped with +24dBi helical
antennas may not work satisfactorily at any
distance less than 1.3 kilometers.
The procedure for pre-installation testing is as follows:
1) After configuring each of the two WlSL systems, disconnect power to both of them.
2) Carefully remove each RWM from its antenna using the Allen key supplied in the System
Installation kit. Set aside the antennas for later rte-attachment.
3) Place the two RWM units on a flat surface about 2-3 feet apart, with their antenna
sockets uppermost. Connect the RF emulation cable between the two sockets.
4) Connect each RWM to its NIM (if not already connected), using the 3-foot cables
supplied in the System installation kit.
5) Power up both systems. Within about 20 seconds, the green LED on each RWM should
turn on solidly and the red LED should be off. in addition, the ‘Lock’ (LCK) indicator on
the NIM front panels should both be on (green), and the ‘Error’ (ARQ) indicator should
be off. If this is the situation, the two WISL systems are communicating satisfactorily,
and you can move on to step 6), Otherwise, refer to Troubleshooting (Section 3.5.1}
below.
6) This step is optional. If you have the necessary equipment available for transferring user
data across the link, make the necessary connections to the two NIMs, and ensure that
data transfer is working correctly. If not, refer to ‘Troubleshooting’ (Section 3.5.1) below.

Wireless lntemet Service Link - User‘s Manual Section 4: Operation
3.7 Installing the RadioWire Modem
This procedure assumes that suitable locations have been selected for installation of the
equipment at both ends of the link, and that poles or towers are available on which to mount
the HadioWire Modems. it also assumes that during the pre»insta|lation survey, a suitable
route was determined tor running the serial cable down irom the RWM to the NIM, at each
end of the link.
CAUTION
For compliance with safety regulations, the
Radlowire Modem must be grounded to
earth. It is recommended that a metal pole
be used for mounting the RWM, and that
the pole itself has a substantial connection
to an earth grounding system.
Take the lollowing items up to the roof area where the RWM is to be installed:
- RadioWire Modem
- Antenna and its assembly fasteners
- Mounting bracket and assembly fasteners
Also, the following items from the System Installation kit (or suitable equivalents):
- Cable pull grip
- Loop-back terminator lor RWM end of cable (a component of the cable
assembly/continuity tester tor the RWM-to-NIM cable)
- Allen key, screwdriver and wrench
- Compass
3.7.1 Attaching the RWM and Antenna to the Pole
With all the necessary equipment gathered at the mounting site, the next step is to install the
mounting bracket assembly. Figure 3-9 shows how this is done. Position the bracket so
that it is lacing approximately in the direction of the remote site, and is at the desired height
on the pole. Use the compass provided in the System installation kit to set the azimuth, it
the remote location is too distant to be seen with the naked eye. Note that the azimuth
values of one site with respect to the other were entered on the Configuration Worksheet
during the link-planning phase. Tighten the mounting bolts enough to allow the bracket to
bear the weight of the modem and antenna.
The next activity depends on which antenna you are using. In the case of the 1—meter
antenna, it must first be assembled. Attach the 3 legs to the main dish, using the bolts,
washers and nuts provided, and then attach the modem-mounting plate to the legs (see
Figure 3-10). The other two antennas do not require assembly.
Now attach the RadioWire Modem to the antenna, using the four knurled Allen screws
provided. Refer to Figures 2-3 through 2-5 for the way in which the two parts lit together.
3-11 DRAFT
Wireless Internet Sen/ice Link ~ User's Manual Section 4: Operation
Attach the combined RWM/antenna assembly to the mounting bracket on the pole. Once
again, the method of attachment for the 1~meter antenna is different than for the other two
antennas. ("' 1-meter antenna TBD "').
For the two smaller antennas, it is the RWM that attaches to the mounting bracket. On the
rear of the RWM enclosure, there is a metal strip that serves as a hook. lt allows the FlWM
to be hung on the mounting bracket in the correct position for the large knurled fasteners to
be screwed into the RWM (Figure 39). This hook-and-Iip system makes it possible to
complete attachment of the RWM/antenna assembly using only a single hand, which may
be necessary in situations where you need to use your second hand for support.
Later on, elevation and azimuth adjustments will be made via the mounting bracket, in order
to align the FtWM units at the two ends of the link. But for the moment, the next step is to
install the cable irom the roof down to the NIM location. Begin by securely connecting the
cable to the FtWM. This will anchor the upper end of the cable while the other end is being
pulled down.

3.7.2 Cable Installation
At this point, you must determine whether a cable puller tool will be needed. For example, if
the cable will be run external to the building walls, the tool will probably not be needed
(Figure 3-11). Similarly, if a clear vertical path is available within the wall cavity, the cable
can be installed without the need for a puller.

Figure 3-11. Internal and External cable Homing
However, cable routing is typically not as straightforward as shown here. Often, obstacles
within the wall cavities must be circumvented, or the cable must travel through a
combination of wall and floor cavities. in these cases, use a cable puller, starting from the
NIM location and working the steel tape up to the root.
Next, return to the root, and slide the cable pull grip fully over the open end ol the cable,
ensuring that no slippage occurs once the grip is in place (Figure 3-12). Now connect the
loops at the ends at the cable pull grip and the steel tape, using a nylon tie wrap threaded
through them both. Trim the free end of the tie wrap, so that it will not catch on anything as
it passes through wall and/or floor cavities.
Return to the NIM location. and proceed to carefully reel-in the steel tape until the cable
reaches you. During this procedure, it may be useful or necessary to have the assistance of
a second person on the root to feed the cable, ensuring that it does not get tangled.
You are now ready to install the 08-25 connector on the NIM end of the cable. Remove the
cable pull grip from the cable end, by pushing it off from its open end. This compresses the
mesh, thus releasing its friction grip on the cable and allowing it to slide oft.

Wireless Internet Service Link - User's Manual Section 4: Operation
Separate the two halves of the DB-25
connector shell and remove the main body
(see Figure 3-13). Using the pin-out
information provided in Appendix F,
carefully insert the pins into the numbered
holes, from the rear of the main body.
Ensure that all pins are fully seated and
protrude from the connector an equal
amount. Clamp the two shell halves back
over the cable and main body assembly,
ensuring that the braided grounding sheath
of the cable makes full contact with the
shell halves at the cable-entry collar. Insert
and tighten the screw that holds the two Figure 3.12, Cable pu|| Grip
halves together.
At this point you may optionally test the
complete cable for correct assembly and lead
continuity, using the tester provided in the
System Installation kit. To do so, go up to the
root, disconnect the cable from the RWM, and
install the loop-back terminator on the cable
connector. Fleturn to the NIM location and
install the display terminator component of the
tester.
("'" Add tester operating procedure "")
After removing the test terminators. reconnect
the cable to the RWM.

3.8 Installing the Network Interface Module
The Network Interface Module must be located in the vicinity of the user equipment to which
it will be connected. It may either be installed as a freestanding unit on a suitable surface
such as a shelf, or a pair at NIM units may be attached side-by-side and rack-mounted in a
standard 19" rack. A special RadioConnect Universal Ftack—Mount kit (Figure 3-14) is
available from your reseller for this purpose (part number 250-0001-00).
It multiple WISL systems are being installed at the same location, they must be inter-
connected using the synchronization cables provided. Fteter to Section 2.2.3 for details of
how to I'daisy-chain" multiple NIM units together.
After physically installing the MM unit(s), connect the cable lrom the RWM, to the
appropriate DB-25 socket on the rear panel.

3.8.1 Electrical Requirements
The system is now ready to be powered up. Connect the power cord to the NIM. For
compliance with safety regulations, the NIM must be connected to a properly grounded
electrical circuit.
The foregoing procedure for mounting the RadioWire Modern and antenna, installing the
RWM-to-NIM cable, and installing the Network interface Module, must next be repeated for
the WISL system at the other end of the link. Once this has been done. you are ready to
proceed with alignment of the systems.
3.9 Antenna Alignment Procedure
With power applied to both WISL systems, return again to the roof at one end of the link.
inspect the LEDs on the underside of the RadioWire Modeml If the green LED is on solidly,
and the red LED is off (Le. not flashing), no further adjustment is needed Simply tighten all
bolts and fasteners as much as possible, using the tools provided.
If the status of the LEDs is not as required, carefully loosen the mounting bracket bolts just
enough to be able to rotate the Modem around the pole. Be sure that while you do this, you
support the unit so that it does not slide down the pole. Next, adjust the azimuth in small
increments to the left or right, until the optimum LED status is achieved. If it is not possible
to find an ideal position at which the green LED is on solidly and the red LED is fully off, then
the best position is that at which the flashing of the red LED is minimized. Once this is
accomplished, tighten the mounting bracket bolts as much as possible.
You may also try optimizing the LED status by adjusting the elevation angle of the FtWM.
Do this by loosening the vertical tilt bolts on the mounting bracket, then tilting the unit up or
down in small increments
Once the best possible combination of red and green LED status is achieved, tighten all
bolts and fasteners as much as possible.
Repeat this alignment procedure at the other end of the link.
