System
Introducing the WaveACCESS NET Product
Family1
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 SpreadSpectrum (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.
1-2WaveACCESS NET 2400 Installation Guide
Introducing the WaveACCESS NET 2400
System
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.

WaveACCESS NET 2400 Installation Guide1-3
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 Site1
Internet
WaveA CCESS 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 co v ers 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 Ruggedized Unit1
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 W aveA CCESS NET 2400 system is fully compatible with
the previous WaveACCESS NET version, it provides enhanced
functionality, as follo ws:
■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.
WaveACCESS NET 2400 Installation Guide1-7
Introducing the WaveACCESS NET 2400
System
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 Installation2
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.

Electrical Power Requirements2
This section provides guidelines for the installation of AC or 48VDC
electrical power to the base station, as follows:
■General Requirements, page 2-7.
■CU232 Power Requirements, page 2-7.
General Requirements2
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.
CU232 Power Requirements2
Each CU232 requires 24-48VDC, 15 Watts, which is supplied by
the power/data adapter.

Grounding and Lightning
Protection Bonding Requirements2
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 Requirements2
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.
2-8WaveACCESS NET 2400 Installation Guide
WaveACCESS NET 2400 Base Station Site
Preparation
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.
