Introducing the WaveACCESS NET Product
Family 1
The WaveACCESS NET system is a radio-based, high-capacity,
high bit rate, low-cost packet switched wireless system that
operates in the 2.4 Ghz ISM unlicensed band to provide
point-to-multipoint wireless Internet access. It is designed to
provide communications for several hundred users simultaneously
accessing the Internet or intranet.
WaveACCESS NET employs Frequency Hopping Spread-
Spectrum (FHSS) technology at data rates of 3.2 and 1.6 Mbps.
The fully digital FHSS radio provides protection against
interference and enables operation of collocated systems, thereby
increasing overall data throughput. WaveACCESS NET has been
optimized for IP traffic and provides high-speed networking at
distances of several miles.
The WaveACCESS NET system consists of a central site known
as the base station, and up to several hundred remote sites. The
base station is where the system links to a backbone, for example,
telephony, satellite, wireless, or digital cable data transmissions.
The WaveACCESS NET CU232 sits at the base station.
The remote sites are the user locations, where remote
WaveACCESS NET xDR232 units act as LAN adapters.
Introducing the WaveACCESS NET 2400
System
WaveACCESS NET 2400 Installation Guide 1-3
The WaveACCESS NET system is comprised of the following:
■WaveACCESS NET CU232: A wireless point-to-multipoint
central unit that can support up to 60 remote units at a data
rate of 3.2 Mbps each. Using unique RFStacker™ technology,
up to ten WaveACCESS NET CU232 units can be collocated
in a single site, creating a cell of up to 600 remote units at a
data rate of up to 25 Mbps. A remote unit does not necessarily
indicate a single user (for example, an MDR232 can support
an entire LAN). Therefore, the actual number of users the
WaveACCESS NET CU232 is able to support is considerably
higher than the number of remote units.
Figure 1-1 WaveACCESS NET CU232
Introducing the WaveACCESS NET 2400
System

■WaveACCESS NET SDR232: A standalone wireless LAN
adapter (remote unit), including a built-in antenna, designed to
connect to any computer’s Ethernet adapter card and allow
fast linking of any workstation to the Internet or Intranet. This
allows the user access to the full bandwidth, without having to
share the capacity with multiple users on a network.
Figure 1-2 WaveACCESS NET xDR232
■WaveACCESS NET MDR232: A multidrop remote unit,
including a built-in antenna, that provides a bridging function
and enables a complete LAN to be connected over a wireless
network. This unit has particular application for a small office
environment, in which a single MDR232 would enable all the
computers to access the Internet.

Sectorization of the Central Site 1
WaveACCESS NET CU232 units are typically installed in business
or residential areas which do not have well-defined boundaries. It
is not always possible to place the base station, with the central
units and antennas, in the optimal location. Therefore, the
WaveACCESS NET system provides the ability to sectorize the
base station by using multiple CU232 units, each of which covers a
sector of the total area to be covered.
This allows an increase in cell range from approximately two miles,
for an omnidirectional 8dBi antenna, to approximately seven miles
for a 20dBi panel antenna.
If you have many users in one area, you may have more than one
CU232 covering the same area to provide optimal throughput for
all the users.

WaveACCESS NET 2400 Installation Guide 1-7
WaveACCESS NET Ruggedized Unit 1
The WaveACCESS NET 2400 units are fully ruggedized and
suitable for outdoor installation, in weather conditions of -40°C to
55°C.
An internal antenna is embedded in each unit, although there is
also an option to use an external antenna for wider coverage. A
single flexible cable is used to transmit data and supply the unit’s
power. The WaveACCESS NET 2400 product now includes a
power/data adapter that connects to the AC power supply directly
and provides an Ethernet connection.
While the WaveACCESS NET 2400 system is fully compatible with
the previous WaveACCESS NET version, it provides enhanced
functionality, as follows:
■Firstly, the fact that the unit is ruggedized and has an
embedded antenna precludes the need for a long RF cable
connecting the indoor unit to its external antenna (with its
inevitable losses). Thus, the signal quality and the effective
ranges are improved.
Increased maximum range enables ISPs to accommodate
more users with a higher data rate in that cell and at the same
level of service. This benefits both ISPs and users of the
system, as users with a low data rate use more bandwidth
when transmitting the same data, than users with a higher data
rate.
■Secondly, the WaveACCESS NET 2400 units custom cable
connects to both the AC power supply and the Ethernet via a
single box, as opposed to the two boxes (one each for power
supply and Ethernet) in the previous version. The cable itself is
thin and easy to manipulate and enables the unit to be placed
up to 100 meters from the power supply.
■Thirdly, the WaveACCESS NET 2400 is easier to install.
Introducing the WaveACCESS NET 2400
System
1-8 WaveACCESS NET 2400 Installation Guide
You have the option to set up an external antenna for wider
coverage than is provided by the internal directional antenna.
When an external antenna is used, it is connected directly to the
radio output.

Tower Pipe Installation 2
It is recommended that towers have a wind rating of 100mph with
5, 10, or 15 CU232s. Each CU232 will experience 80 kg (175 lbs)
of wind load at 100mph w/wind factor normal to CU232. The tower
should be able to support 1, 2, or 3 sets of CU232s.
The installation height of the antenna must be approximately 15 m
above the surrounding average building height, or as specified by
the field RF engineer.
The pipes to which the CU232s will be attached should be
mounted either on a tower, or on the sides of a building near the
roofline, at a height specified by the field RF engineer.
When tower installation is performed, the pipe should be installed
around the tower with an angular separation of 72 degrees. In
certain instances, it may not be possible to install the support pipe
at 72 degree intervals. The ability to swing the CU232 from side to
side over an arc of approximately 45 degrees is required. One of
the support pipes should be mounted on the tower so that it faces
North. A subsequent pipe can then be installed at 72 degree
increments from the reference Northward facing pipe.
When performing the installation of five CU232s on a building, the
support pipes should be located on a common wall. The other
three CU232s can be installed on the other three sides of the
building. The clearance requirements should comply with
Figure 2-1.
The minimum distance between any CU232 support pipe and
other wireless telecommunication equipment should be
two meters.

■CU232 Power Requirements, page 2-7.
General Requirements 2
All the AC wiring and over-current protection must be provided in
accordance with the National Electric Code (NFPA-70) and local
electrical codes. An appropriate earth-ground connection is
required before the commercial AC service can be connected. The
base station AC input power is single phase, nominal 120/208 or
120/240 Vrms, 50/60 Hz. Nominal voltage is defined as 120 Vrms
between line(s) to ground, and 208 Vrms or 240 Vrms line to line.

Grounding and Lightning
Protection Bonding Requirements 2
This section provides information on grounding and lightning
protection requirements for a WaveACCESS NET base station, as
follows:
■General Requirements, page 2-7.
■Lightning Protection, page 2-10.
General Requirements 2
The WaveACCESS NET base stations are susceptible to lightning
surges due to their association with towers and antennas.
Therefore, it is imperative that all base station components be
properly grounded, providing a low impedance path to earth. The
grounding conductors must be as straight and short as possible
and should not have any sharp bends or loops.
The CU232 cable shield must be bonded at the top and bottom of
the vertical run, and where it comes near the equipment. The tower
or metallic support of the antenna must also be bonded to the
grounding system. In addition, the surge protection device must be
bonded to a nearby ground bus bar that is connected directly to the
grounding electrode system.
All metallic objects within 2 meters (6 feet) of the grounded
equipment must be bonded to the grounding system.
All base station equipment must be bonded to a grounding
electrode system, for example, buried ring ground, copper clad
rod, electrolytic rods, metallic water pipe, and so on.
WaveACCESS NET 2400 Base Station Site
Preparation
WaveACCESS NET 2400 Installation Guide 2-9
The minimum requirement for buried ground conductors is
#2 AWG bare, solid, tinned copper wire. Exterior ground
conductors must be either solid, bare, tinned copper or stranded,
insulated (for sunlight resistance) copper cable. The interior ground
cable must be stranded copper with green insulation type THAWN
or equivalent.
All grounding system material, namely, cable, connectors, buses,
and so on, must be made of high quality materials that are
resistant to deterioration and that require little or no maintenance.
An exothermic weld is recommended for grounding connections,
where practical. All below-grade connections must be
exothermically welded. In addition, compression type, long barrel,
two-hole (0.75" center) lugs or double crimp “C” Taps are also
acceptable. The metal contacts to which connections are made
must have a bare bright finish, and be coated with an anti-oxidation
material.

Preparation
4-2 WaveACCESS NET 2400 Installation Guide
Overview 4
The remote units (xDR232s) are the user locations, where remote
WaveACCESS NET units act as LAN adapters. There are two
types of remote units, each of which includes a built-in antenna
and interfaces to end user PCs:
■MDR232: A multidrop remote that provides a bridging function
and enables a complete LAN to be connected over a wireless
network. This unit has a particular application for a small office
environment, in which a single MDR232 would enable all the
computers to access the Internet.
■SDR232: A single drop remote that enables single user access
to the Internet. This allows the user access to the full
bandwidth, without having to share the capacity with multiple
users on a network.
The xDR232 provides a reliable air interface capability to the
subscriber. It connects to the end user via a 10Base-T physical
interface supporting the Ethernet protocol. The xDR232 is
physically attached to the outside of a home or office. It measures
34 cm x 31 cm x 13 cm and weighs 4 kgs.
The xDR232 package consists of the following:
■xDR232 unit.
■Power/data adapter.
■Data and power cables.
■Power supply.
■Mounting brackets (vertical/horizontal).

Vertical Surface Mounting 4
This section describes mounting the WaveACCESS NET xDR232
on a vertical surface, as follows:
■Physical Considerations, page 4-6.
■Clearances, page 4-6.
Physical Considerations 4
When you are preparing the xDR232 site for vertical surface
mounting, the structure needs to conform with the basic space and
environmental requirements. The specified area must include the
space required by the xDR232, and the mounting pipe (optional).
Although the mounting pipe is optional, it is highly recommended
that one is used.
When selecting the site for the xDR232, keep in mind that the
maximum cable length allowed from the xDR232 to the PC/
Ethernet Hub connector is 100 m (300 ft.), as shown in Figure 4-3.
Clearances 4
The spacing requirements for the xDR232 are critical. It is
essential that enough clearance is provided so that the xDR232
can swing up and down, and side to side. A minimum clearance of
33 cm (13 in) is recommended for the xDR232 to swing up and
down, and 81 cm (32 in) to swing side to side.
When mounting the xDR232 with the optional pipe, there is an
additional spacing requirement of 15 cm (6 in) so that the xDR232
can swing in all directions.

■Aligning the xDR232 after Mounting, page 5-24.
Choosing the Optimal Physical Location for
the xDR232 5
Prior to installation it is essential to identify a remote unit
installation site and prospective (intended) base stations for airlink.
Based on customer requests and the RF planning document, the
installers should be provided with a location for the xDR232
installation, the base station(s) locations, and channel numbers for
the most likely base station candidates.
It is recommended that the xDR232 be installed within line of sight
of the CU232. This is not a requirement, but it will improve the
signal quality in certain installations. In addition, it is also
recommended that the xDR232 be mounted in front of a wall or
other structure, to minimize the occurrence of spurious signals
from reaching the unit.
Installing the Remote Units
5-8 WaveACCESS NET 2400 Installation Guide
!CAUTION:
The xDR232s must be grounded to prevent the
accumulation of atmospheric static charge on the chassis
and to reduce unpredictable static discharges that may
result in serious damage to the subscriber’s equipment
(Ethernet hubs, PCs, LANs, and so on), as well as the
remote unit.
Installing the Remote Units
WaveACCESS NET 2400 Installation Guide 5-9
!CAUTION:
When placing the xDR232s, the guidelines detailed in the

3. Adjust the orientation of the xDR232 to establish a “Sync”
condition and maximize the signal strength. The minimum
recommended requirement is that the 10dB indicator is lit.
Record the signal level as indicated by the LEDs. When the
signal measurements are taken, the xDR232 should be
positioned as close to the prospective mounting location as
possible.
4. Reprogram the xDR232 for the other CU232 ESS-ID(s) and
repeat the survey to determine the best direction, location, and
signal strength for the remote unit.
5. For each CU232, record the ESS-ID and the signal strength
and pass this information on to the network planner.

for information.
When an external antenna is required, an omnidirectionl antenna
is used, as described below.
WaveACCESS NET 2400 Antennas
WaveACCESS NET 2400 User’s Guide 7-3
External Omnidirectional Antennas 7
The omnidirectional dipole antennas available for use with the
WaveACCESS NET CU232 are intended for external mounting
and should be used when full 360° coverage is desired. When
these antennas are mounted on a mast, they should be located as
high as possible in order to avoid any other object being located
beside it.
The OM10 (and to some extent the OM08) omni antenna has a
very narrow elevation (vertical) beamwidth. Both the height and
distance separation between the two sites must be taken into
consideration when selecting this antenna. In order to maximize
the coverage area, you may want to order the appropriate down tilt
option ahead of time, if it is available for that particular antenna.
The following table describes the physical characteristics of the
omni antenna:
NOTE:
Some antennas have a female N-type connector, and
some antennas have a male N-type connector. In case of
the latter, a female-to-female N-type adapter should be
supplied with the antenna.

Antenna Options and Specifications 7
The table on page 7-5 displays the antenna options and their
specifications. These figures reflect a 6-10 dB fade margin over
ideal free space propagation and use the shortest permitted cable
(see the minimum cable segment length in the table on
page XXX). It is assumed that the remote end (WaveACCESS
NET SDR232 or WaveACCESS NET MDR232) uses its largest
antenna, PG24, and the shortest permitted cable. The central
antenna is assumed to have a horizontal deviation from the remote
equal to a quarter of its horizontal beamwidth.
NOTE:
Irrelevant in the case of Omni antennas.
Where antennas with narrow elevation beamwidths are employed,
and the remote unit is located at a significant height difference, the
remote unit may not be within the main beam of the antenna. To
avoid this situation, optimize the antenna tilt for the remote unit.

This section provides a basic guide for aligning antennas for a high
gain link. It also explains the basics of link budget calculation, as
follows:
■Antenna Placement and Alignment, page 7-12.
■Calculating the Link, page 7-15.
■Calculating the Antenna Elevation Angle, page 7-16.
■Setting the Azimuth Alignment, page 7-18.
■Directional Alignment, page 7-19.
■Software for Antenna Alignment Calculations, page 7-20.
For more information on using the LEDs to measure the strength of
the signal, refer to Chapter 5 ”Installing the Remote Units”.
Antenna Placement and Alignment 7
When you are building a central site, the type and location of the
antennas must be carefully chosen in order to enable optimal
communication between the collocated central units and the
remote units.
The following factors must be taken into consideration when
choosing antennas and their placement at the central site:
■Boundaries.
■Fresnel Zone.
■Antenna Elevation.
WaveACCESS NET 2400 Antennas
WaveACCESS NET 2400 User’s Guide 7-13
Boundaries 7
The boundaries are defined by calculating the coverage range of
the antenna, based on antenna beamwidth and gain specifications.
Basically, the boundaries of the antennas used at a central site
must be compatible with the area you need to cover. Keep in mind
that the higher the gain, the narrower the beamwidth. Thus, the
antenna may cover a longer distance, but a narrower sector.
When placing antennas at the central site, you must take into
account the total area you want to cover. You can then calculate
the sectors to be covered by each antenna, based on the predicted
range calculation, according to the specifications of the specific
antenna.
It is recommended that the boundaries of the antennas overlap a
little, so that there are no gaps in the coverage area. However,
make sure that they do not intersect one another, as this will cause
disturbances in performance.
In order to calculate the link for antenna alignment, you need to
consider the following basic data:
■Distance between the central unit antennas and the remote
unit.
■Height difference.
■Types of antennas being used.
■Types of cables, and losses for the leads being used.
After obtaining this data, the expected path loss and required
antenna elevation angle can be calculated. To assist in calculating
the link loss and fade margins, a special Excel-based worksheet is
provided on the WaveACCESS NET software diskette.
WaveACCESS NET 2400 Antennas
7-14 WaveACCESS NET 2400 User’s Guide
Fresnel Zones 7
When positioning the antennas, you need to ensure that there is
line of sight between the central site antennas and the remote unit.
Most importantly, the first Fresnel zone must be clear. The
following diagram illustrates how to calculate the Fresnel zone:
Figure 7-1 Calculating the Fresnel Zone
Antenna Elevation 7
Antennas in a collocated system are usually installed with 0° tilt.
However, where antennas with narrow elevation beamwidth are
used, and the remote unit is located at a significantly different
height, you may have a situation where the remote unit is not within
the main beam of the antenna. In such a case, you need to
optimize the tilt of the remote unit. For information about
calculating the antenna elevation angle, refer to page 7-16.

Calculating the Link 7
To calculate the link, the following basic data is required:
■Distance between the two points.
■Height difference between the two points. If the height
difference is larger than the antenna vertical beamwidth
allows, it will affect the elevation setting of the antenna.
■Type of antenna being used (i.e., gain and beamwidth).
■Type of cables, and losses for the leads being used.
After obtaining the above data, the expected path loss and
required antenna elevation angle can be calculated.
WaveACCESS NET’s Excel-based calculation tool, which is
provided on the enclosed software diskette, is used to calculate the
free space path loss and fade margin for a specific link. Use this
spreadsheet to determine your optimal setup and expected
performance. Refer to the section,

Calculating the Antenna Elevation Angle 7
The antenna elevation angle at each point is calculated in order to
achieve maximal performance. This is done using the following
equation:

directed upwards by α and the higher antenna must be tilted
downwards by α.

The elevation alignment is made in the following manner:
The higher antenna must be aligned first.
To align the antenna: 7
1. Attach a weighted string to the higher antenna.
2. Measure the distance (G) and the antenna diameter (D) and
use the equation shown on the preceding page to calculate α.
3. Use the same method to align the second antenna to the
maximal reception from the first antenna.
NOTE:
If the angle α formed by the height of the antennas has a
difference of less than the antenna’s vertical opening β by
a factor of at least four (i.e., β ≥ 4 α) it is not necessary to
perform vertical alignment. In that case, the antenna
should only be aligned to the horizontal.

Setting the Azimuth Alignment 7
The next step in setting up the link is the azimuth (or horizontal)
alignment. In order to do this, you must achieve as accurate a
direction as possible from one antenna to the other. This can be
done using a good map or GPS system that can give accurate
coordinates and point you in the right direction. If none of the
above is available, a good compass and a pair of binoculars
(to see the other end) can be used.
To set the azimuth alignment: 7
1. Align each antenna directly towards the other.
2. Lock one of the antennas.
3. Adjust the unlocked antenna in order to find and prove that the
antenna is receiving the best possible signal strength. Do this
by moving it horizontally in one direction until the signal
strength peaks and then goes down by at least 5 dB (as shown
using the RSSI indicator in the monitor of each unit).
NOTE:
It is important to move the antenna at an angle of at least
four times its horizontal opening to ensure the antenna’s
main lobe is being measured, not a side lobe with its
subsequent low power.
4. Now turn the antenna in the opposite direction and repeat the
procedure in number 3.
WaveACCESS NET 2400 Antennas
WaveACCESS NET 2400 User’s Guide 7-19
5. Return the antenna to the highest peak previously achieved
and lock it in place, using the correct tools.
NOTE:
If a signal cannot be received from the other system,
and/or the units do not synchronize, even though there
should be enough fade margin for the link, you need to
move the antenna at a lower speed.
Attempt to move the antenna laterally at a rate of 1° − 2°
per second to allow the unit to properly detect the other
unit’s signal.
6. Repeat the above steps at the second site.
!WARNING:
Make sure that the antennas are tightly locked in place,
otherwise harsh meteorological conditions (strong winds,
storms, and so on,) may cause the settings to change.
Directional Alignment 7
This process is comprised of the following steps:
1. Aligning the two antennas with a compass to the correct
direction.
2. Fine-tuning one antenna to its maximum Rx strength.
3. Fine-tuning the second antenna until it reaches maximum Rx
strength.

Software for Antenna Alignment
Calculations 7
Since WaveACCESS NET systems in the ISM band use frequency
hopping, a special feature has been included to help with the
installation of high gain point-to-point links. This software utility is
capable of:
■Limiting transmission to one frequency only.
■Providing statistics about noise level in the area.
■Giving RSSI (signal strength above threshold) readings.
These special features are accessed through the ASCII monitor
system of the units.
The special screen which enables setup of the unit for single
frequency transmission is available only to Authorized
WaveACCESS NET resellers and distributors, and may not be
used by the end user.
NOTE:
Most countries do not allow an ISM band Spread
Spectrum device to transmit only on a single frequency.
This utility is to be used very sparingly, and only for
antenna alignment purposes.
In order to maximize compliance with laws and
regulations, the unit reverts to Hopping mode whenever it
is reset.

Lightning Protection
THIS IS AN INCOMPLETE DRAFT.
This section provides information on the reasons and methods of
lightning protection for the WaveACCESS NET product family, as
follows:
■Why is Lightening Protection Required?, page A-2.
■Methods of Lightning Protection, page A-3.
■Lucent Technologies Lightning Protection Unit, page A-7.
■Considerations for LPS Design, page A-9.
The CU232 and xDR232 enclosure and the I/O cable shielding
must be properly grounded in order to provide protection against
lightning, surges, and static buildup. Failure to do so will invalidate
the product warranty.
!CAUTION:
The CU232 and xDR232 bracket must be grounded using
a minimum of a No. 10 AWG wire (6 AWG in Canada), or
by adhering to the local electric code.
The CU232 and xDR232 include Gas Discharge Tubes (GDT) as
secondary lightning protection devices. These devices clamp the
excess voltage, surge, or static buildup that exceeds 90 Volts.
However, other factors may warrant additional optional protections
for the unit, especially in geographical areas where lightning
storms are a common occurrence.
Appendix A: Lightning Protection
A-2 WaveACCESS NET 2400 Installation Guide
Why is Lightening Protection
Required? 1
The need for protection is influenced by the Network or Service
Provider’s assessment of the importance of the WaveACCESS
NET element. This includes the following:
■Likelihood of lightning strikes.
■Cost of a Lightning Protection System (LPS).
■Cost of a voided warranty and the replacement of system
elements.
■Cost of repair work.
■Cost of information that is lost or destroyed.
■Loss of revenue.
■Relative risk of fire and electric shock.
■Potential health and safety risks.
The British Standard BS 6651: 1992 provides a simple
mathematical overall risk factor analysis for assessing whether a
structure requires protection.
Appendix A: Lightning Protection
WaveACCESS NET 2400 Installation Guide A-3
Methods of Lightning Protection 1
The best method to use to reduce the risk of lightning strikes is
avoidance. The CU232 and xDR232 must be mounted within a
zone of protection, namely, the 45o lightning protection cones
provided by the building structure, or an existing LPS. The 45o
cone of protection applies to tower-mounted units as well, as
shown in Figure A-1 and Figure A-2.
!CAUTION:
Failure to provide a lightning protection zone will void the
warranty.

If the CU232 and/or xDR232 cannot be mounted within a zone of
protection, an LPS must be introduced or extended to provide a
new zone of protection for the CU232 and/or xDR232, as shown in
Figure A-2, Tower B.

A braided wire is typically used to ground the CU232 or xDR232 to
the structure’s main grounding point. The existing LPS is also
connected to the same point. The grounding point for the CU232 is
located on the right side of the mounting bracket.

The grounding point for the xDR232 is a threaded stud on the
bracket, as shown in Figure A-4.
Figure A-4 xDR232 Bracket and Grounding Stud Location
The bare, non-insulated drain lead of the I/O cable, which includes
the 10Base-T wires and power leads, must be connected to the
ground terminal (green-colored) on the plug-in terminal block on
the CU232 or xDR232.
The shield and drain wires, inside the power/data adapter, must be
cut back to the insulation to prevent the current from flowing back
into the building.

considered when a Lightning Protection System must be installed
or extended.

Lucent Technologies Lightning
Protection Unit 1
Additional protection in lightning-prone areas can be provided by
installing a Lucent Technologies Lightning Protection Unit, as
shown in Figure A-5.
Figure A-5 Lightning Protection Unit
This is an outdoor unit that provides secondary protection to the
incoming cable. It includes gas discharge tubes for line protection
and a fusible link between two earth studs. When high current
develops between the incoming and outgoing earth studs the
fusible link provides extra protection. This device may not be
required for every installation.
NOTE:
The Lightning Protection Unit is not currently available.

A-8 WaveACCESS NET 2400 Installation Guide
Lucent Technologies’ products provide only secondary protection
against lightning discharges. Primary protection is provided by
locating the products in a recognized “zone of protection”,
connecting to a LPS, and complying with the applicable
governmental regulations. There can be no assurance that the
products will survive electrical discharges from lightning at or in the
vicinity of the products even when primary protection is in place.
Lucent Technologies does not warrant its products against damage
from such discharges. All costs to repair such damage for which
Lucent Technologies is not responsible, including any costs of
restoring such secondary protection, shall be the responsibility of
the party seeking such repair.
Appendix A: Lightning Protection
WaveACCESS NET 2400 Installation Guide A-9
Considerations for LPS Design 1
The following design recommendations should be considered
when a Lightning Protection System (LPS) must be installed or
extended. These recommendations are also affected by local
regulations that may impose additional standards. These are the
principal elements of an LPS:
■Air termination networks
— New LPS or system integration into an existing LPS.
■Down conductors
— Types of conductors and spacing.
— Routing of conductor.
■Earth termination networks
— Protecting equipment and buildings.
— Protection of people.
— Soil conditions namely, temperature, moisture, chemical
composition.
— Choosing a grounding system namely, design life, soil
resistivity, design.
■Bonding to prevent side flash.
Earth Termination Networks 1
It is recommended that deep-driven earth electrodes be used, as
they are more likely to reach permanent moisture and be
unaffected by seasonal changes. Where it is impossible to drive
earth rods deep enough, several rods may be used together in a
matrix. Although it may be possible to use the reinforcing bars
within the structure's foundations, precautions must be taken to
ensure that there is electrical continuity.
Appendix A: Lightning Protection
A-10 WaveACCESS NET 2400 Installation Guide
NOTE:
Due to increased use of plastic/PVC components, buried
water pipes are not considered reliable.
Bonding 1
All metal work on or around a structure must also be bonded to the
LPS. When an LPS is struck, its electrical potential with respect to
earth rises. Unless all metal work within a fixed distance is bonded,
the discharge will seek an alternative path to earth by side flashing
to other metal work in or on the structure. Tables for calculating
suitable "isolation" distances are listed in BS 6651 (British
Standard).
System certification and maintenance 1
Installing an LPS entails much more than placing a copper rod in
the ground and connecting the WaveACCESS NET unit enclosure
and mounting pole to it. It is recommended that a local lightning
protection consultant or installation company be engaged to carry
out the design, installation, and maintenance of such systems.
Once a system has been designed and installed, it may be
required to be inspected and certified to be in compliance with
local regulatory standards. Annual inspection and testing is
recommended to ensure that the LPS still functions according to its
design specification.
Lightning protection system suppliers 1
Lucent Technologies makes no recommendations on suppliers of
lightning protection systems. The following is for reference only.

Example of Lightning Protection System 1
!WARNING:
The following design does not constitute a proposal. It may
be necessary to substitute components or to alter the
physical layout from that shown, depending on local
regulations. This is only an example.
NOTE:
To avoid the effects of galvanic corrosion, it is essential
that dissimilar metals not be bonded together or in physical
contact. For example, if the mounting pole is aluminum,
then an aluminum Air Terminal should be used. Any
transition from copper to aluminum must be made via an
appropriate bimetallic connector.
Appendix A: Lightning Protection
A-12 WaveACCESS NET 2400 Installation Guide
Copper or aluminum can be used above ground for the LPS;
however, because the WaveACCESS NET unit is made of
aluminum, an aluminum system is recommended. Where the
system enters the ground, a bimetallic coupler must be used.
Copper or stainless steel should be used for the LPS below
ground; stainless steel should be considered if galvanic corrosion
is an issue.
The item numbers shown in Table A-1 and Table 1-2 refer to the
elements shown in Figure A-6.
