About W-OFDM
The Libra system uses Wi-LAN’s patented Wide-band Orthogonal Frequency Division Multiplexing
(W-OFDM) technology to process, transmit and receive data in parallel fashion over the air. W-
OFDM divides a wide RF frequency band into several subchannels that work together to deliver
data, similar to splitting a road into several lanes that together can handle more traffic than a single
lane.
W-OFDM offers many advantages, including effective use of bandwidth, resistance to interference,
ability to take advantage of multipath characteristics, and advanced error correction and recovery.
Because data is spread across all the channels, interference usually affects only a few channels
rather than all channels, and lost data can be easily recovered. Since W-OFDM is insensitive to
interference, the amount of ongoing tuning, adjustment and maintenance is minimized. Both
multipoint networks and point-to-point backbone systems are supported.
The following diagram illustrates the main concept behind W-OFDM. The available frequency
spectrum is divided into subchannels. Each subchannel is orthogonal, meaning that the peak signal
strength of each signal occurs at the null or point of minimum signal strength of its neighbor, so
adjacent subchannels do not interfere with each other. Data is carried in parallel across the
subchannels.

About Point-to-Multi-Point (P-MP) Systems
June 2003 Rev 0 15
About Point-to-Multi-Point (P-MP) Systems
Two kinds of equipment are required for a wireless P-MP link: Access Point (AP) equipment and
Customer Premise Equipment (CPE). AP equipment is located at the service provider’s site and
CPE equipment is located at the customer’s site. The LIBRA 5800 P-MP product is available as an
AP, a CPE with integrated 23 dBi antenna or an LCPE for connection to higher gain external
antennas.
LIBRA 5800 P-MP System Components
Access Point (AP) Equipment
The AP controls communication within the wireless network and is the main access point to the
Ethernet.
The access point communicates with the CPE’s in the system to provide each CPE with Access to
the main network (ie Ethernet). The access point is typically located at a distance away from the CPE
that will provide adequate radio signal strength for the specified data rates.

Description
16 Libra 5800 Series User Guide
The Access Point is responsible for any CPE data management functions.
The Libra 5800 AP consists of three parts: 1) AP radio unit, 2) Ethernet Power Inserter with CAT-5
cable (bought separately) and weatherproofing kit (included), and 3) the External Antenna and cable
(both bought separately).
•LIBRA 5800 AP– The AP is the main piece of radio equipment. It is designed for outdoor
installation but can also be installed indoors if needed. The AP is equipped with an N-type (F)
RF connector so that the external antenna can be connected to it. Thus many different types
of base stations can be deployed using sectoral, omni or other specialized antennas.
•Ethernet Power Inserter– This piece of equipment is a small box that connects between the
CPE and the P.C. This box also provides power for the AP equipment to run. A CAT-5 outdoor
cable is used to connect the Power inserter to the AP. The weatherproofing kit is used with
standard RJ-45 connector to ensure reliable connection for outdoor systems.
•Antenna and Cable– In order to accomodate different frequency re-use plans and scalability
of the base stations the AP is designed to be used with an external antenna. Antennas and
cables are selected by the user based on the network requirements.
Customer Premise Equipment (CPE)
The CP equipment connects customers to the AP via a wireless link. The link enables customers to
communicate with other users of the wireless network and the Ethernet.
Customer Premise Equipment has two parts: 1) CPE radio unit and 2) Ethernet Power Inserter with
CAT-5 cable (bought separately) and weatherproofing kit (included).
•LIBRA 5800 CPE– The CPE is the main piece of equipment that would normally be installed
outdoors (indoor installation is permitted when feasible) The CPE contains all of the
necessary radio equipment to provide a high-speed wireless link. The CPE also has an
integral antenna such that no RF cables are required for a typical installation.
•Ethernet Power Inserter– This piece of equipment is a small box that connects between the
CPE and the P.C. This box also provides power for the CPE equipment to run. A CAT-5
outdoor cable is used to connect the Power Inserter to the CPE. The weatherproofing kit is
used with standard RJ-45 connector to ensure reliable connection for outdoor systems.
Wireless network activity focuses on the AP, which is both the main access point to the Ethernet
(LAN or WAN) and the destination for CPE-originated communications (CPEs do not communicate
directly with other CPEs—they communicate only via the AP). CPEs complete the customer-end of a
wireless link.
Long Range Customer Premise Equipment (LCPE)
The LCP equipment also connects customers to the AP via a wireless link. The LCPE enables the
customer to reach longer ranges by allowing the connection to a higher gain external antenna. It can
also be used for indoor installation of the units should severe weather conditions require it. The
antenna is then mounted outdoors and connected via appropriate RF cables to the unit. One other
alternative which customers may want to consider is to use lower gain antennas with systems that
are very close to the Base Station to mitigate some interference concerns without recourse to
dynamic power control.
About Point-to-Multi-Point (P-MP) Systems
June 2003 Rev 0 17
The Libra 5800 LCPE consists of three parts: 1) LCPE, 2) Ethernet Power Inserter with CAT-5 cable
(bought separately) and weatherproofing kit (included), and 3) the External Antenna and cable (both
bought separately).
•LIBRA 5800 LCPE– The LCPE is the main piece of equipment. It is designed for outdoor
installation but can also be installed indoors if needed. The LCPE is equipped with an N-type
connector so that the external antenna can be connected to it. Thus the range of the P-MP
system can be significantly increased by use of higher gain antennas. Also, in situations
where very severe conditions may be encountered outdoors the LCPE can be installed
indoors with cabling to the antenna outside.
•Ethernet Power Inserter– This piece of equipment is a small box that connects between the
LCPE and the P.C. This box also provides power for the LCPE equipment to run. A CAT-5
outdoor cable is used to connect the Power inserter to the LCPE. The weatherproofing kit is
used with standard RJ-45 connector to ensure reliable connection for outdoor systems.
•Antenna and Cable– In order to accomodate different range requirements for P-MP links,
the LCPE is designed to be used with an external antenna. Antennas and cables are selected
by the user based on the network requirements.
Radio Operation Background
The Libra 5800 communicates using a technique call Time Division Duplexing (TDD) in both the P-P
and P-MP configurations. TDD uses one frequency for both the Down Link (DL) Transmission (Base
to Remote in P-P, or AP to CPEs in P-MP), and for the Up Link (UL) (Remote to Base in PP or CPEs
to AP in P-MP). The DL and UL transmissions are performed at different times, therefore the system
is known as a Time Division Duplexing system. The available frequency band is therefore separated
into multiple TDD channels allowing for use of the whole frequency bands for very high capacity.
Time Division Duplexing Channels
In addition to using TDD, in a P-MP system, the AP and CPE also use Time Division Multiplexing
(TDM). TDM is a process of using time slots to allow the AP to transmit to multiple CPEs during a
single transmit cycle. During the Up Link cycle each CPE is polled and if it has data it transmits in
turn. This is known as Time Division Multiple Access (TDMA). All CPEs thus share the bandwidth
available by allocating time slots in turn to each of the units on both transmit and receive channels.
The following diagram shows TDM in a DL and TDMA in the UL. Each slot is allocated to a different
CPE. In the Wi-LAN system each slot may vary in time depending on traffic destined for each of the
CPEs. CPEs that are not very active will also be polled less frequently thus reducing the latency of

the system. Once they are ready to transmit or receive they will move up the polling list and will be
polled more often.
Time Division Multiplexing/Time Division Multiple Access (TDM/TDMA)
Antenna characteristics and placement are critical. Because of W-OFDM’s excellent Non-Line of
Sight performance and its resistance to frequency selective multipath fading CPE directional
antennas do not have to be pointed directly at the AP antenna. Having a clear line of sight is always
preferable, but is not necessary with the BWS series. There are cases in which the optimal
performance is acheived when the CPE antenna does not point directly to the AP (e.g. when using
reflection off a nearby structure to avoid an absorbing obstruction).
About Point-to-Point (P-P) Systems
For P-P systems Libra 5800 comes in two versions, the Rapid Deployment (RD) and the Extended
Range (ER) units. P-P links are used when only two locations are connected, for example for
backhaul purposes between P-MP Base Stations and the Network Operating Center for connection
to the Internet backbone, or in situations where throughput requirements between two locations are
such that the bandwidth can’t be shared.
Rapid Deployment (RD) Equipment
The RD equipment is intended for very rapid installation of a P-P link and can be used for links of up
to 16 kms (up to 12 kms at full 32 Mbps bandwidth).
RD Equipment has two parts: 1) RD and 2) Ethernet Power Inserter with CAT-5 cable (bought
separately) and weatherproofing kit (included).
•LIBRA 5800 RD– The RD is the main piece of equipment that is normally installed outdoors
(indoor installation is permitted when the range and link budget allows it) The RD contains all
of the necessary radio equipment to provide a high-speed wireless link. The RD also has an
integral 23 dBi antenna such that no RF cables are required for a typical installation.
•Ethernet Power Inserter– This piece of equipment is a small box that connects between the
RD and the Ethernet network. This box also provides power for the RD equipment to run. A
CAT-5 outdoor cable is used to connect the Power inserter to the RD. The weatherproofing kit
is used with standard RJ-45 connector to ensure reliable connection for outdoor systems.

Extened Range (ER) Equipment
The ER Equipment allows for the use of different external antennas to achieve links of much longer
range (up to 66 kms). It can also be used for indoor installation of the units should severe weather
conditions require it. The antenna is then mounted outdoors and connected via appropriate RF
cables to the unit.
The Libra 5800 ER consists of three parts: 1) ER, 2) Ethernet Power Inserter with CAT-5 cable
(bought separately) and weatherproofing kit (included), and 3) the External Antenna and cable (both
bought separately).
•LIBRA 5800 ER– The ER is the main piece of equipment. It is designed for outdoor
installation but can also be installed indoors if needed. The ER is equipped with an N-type
connector so that the external antenna can be connected to it. Thus the range of the P-P
system can be significantly increased by use of higher gain antennas. Also, in situations
where very severe conditions may be encountered outdoors the ER can be installed indoors
with cabling to the antenna outside.
•Ethernet Power Inserter– This piece of equipment is a small box that connects between the
ER and the Ethernet network. This box also provides power for the ER equipment to run. A
CAT-5 outdoor cable is used to connect the Power inserter to the ER. The weatherproofing kit
is used with standard RJ-45 connector to ensure reliable connection for outdoor systems.
•Antenna and Cable– In order to accomodate different range requirements for P-P links, the
ER is designed to be used with an external antenna. Antennas and cables are selected by
the user based on the network requirements.
