to-point radios represent a new microwave architecture that is designed to address universal
applications for both PDH and SDH platforms. This advanced technology platform is designed to
provide the flexibility to customers for their current and future network needs.
The Challenger L series equipment is based upon a common platform to support a wide range of
network interfaces and configurations. It supports links for 16 x E1, E-3, 1/2 x 100BaseTX
Ethernet, and 1 x STM-1. The radio family is spectrum and data rate scalable, enabling service
providers or organizations to trade-off system gain with spectral efficiency and channel availability
for optimal network connectivity. Challenger L series digital radio enables network operators
(mobile and private), government and access service provides to offer a portfolio of secure,
scalable wireless applications for data, video, and Voice over IP (VoIP).
The Challenger L digital radio family is composed of a Challenger L Indoor Unit and Outdoor
Unit (ODU). The Challenger L IDU is designed to be frequency independent, and the ODU is
designed to be capacity independent. The Challenger L IDU allows selection for multiple
capacity options, modulation types, radio frequency channels and transmit output power
levels to accommodate and adhere to world-wide regulatory and spectral efficiency
requirements. The companion ODU, mounted outdoors, can support frequency bands from
7 to 38 GHz.
The Challenger L IDU supports 1+0 and 1+1 protection and ring architectures in a single 1
RU chassis. The modem and power supply functions are supported using easily replacable
plug-in modules. An additional feature of the Challenger L IDU is provision for a second
plug-in modem/IF module to provide repeater or east/west network configurations.
The Challenger L Digital Radio includes integrated Operations, Administration, Maintenance, and
Provisioning (OAM&P) functionality and design features enabling simple commissioning when the
radio network is initially set up in the field at the customer’s premises. Furthermore, a highlight of
Challenger L radio products is scalability and the capability to support a ring-type architecture.

The recommended maximum length for all cables to terminal equipment is a maximum of 3
meters. The exception to this recommendation is the length of the ODU/IDU Interconnect cable,
which connects the Outdoor Unit to the Indoor Unit.
Power Supply Input
DC Input
-48 VDC
-48v (Isolated Input); 2-pin captive power connector. The
Challenger L Digital Radio requires an input of -48 volts dc
±10% at the front panel DC Input connector. The total
required power is dependent on the option cards and
protection configuration (1+0, 1+1). The Challenger L IDU
front panel power connector pin numbering is 1 through 2,
from left to right, when facing the unit front panel. Pin 1 is the
power supply return and is connected to unit chassis ground
internally. Pin 2 should be supplied with a nominal -48 V dc,
with respect to the unit chassis (ground). A ground-isolated
supply may be used, provided it will tolerate grounding of its
most positive output.
The recommended power input is -44 to -52 V dc at 2 Amps
minimum. It is recommended that any power supply used be
able to supply a minimum of 100 W to the Challenger L IDU.
A mating power cable connector is supplied with the
Challenger L IDU. It is a 2-pin plug, 5 mm pitch, manufactured
by Phoenix Contact, P/N 17 86 83 1 (connector type MSTB
2,5/2-STF). This connector has screw clamp terminals that
accommodate 24 AWG to 12 AWG wire. The power cable
wire should be selected to provide the appropriate current with
minimal voltage drop, based on the power supply voltage and
length of cable required. The recommended wire size for
power cables under 10 feet in length supplying -48 Vdc is 18
AWG.
The Challenger L IDU supplies the ODU with all required
power via the ODU/IDU Interconnect cable. The Challenger L
IDU does not have a power on/off switch. When DC power is
connected to the IDU, the digital radio powers up and is
operational. There can be up to 320 mW of RF power present
at the antenna port (external antenna version). The antenna
should be directed safely when power is applied.

Figure 1-4. Challenger L IDU Block Diagram
Figure 1-4 shows the Challenger L IDU and interfaces from a functional point of view. The functional
partitions for the I/O, Modem/IF, and power supply modules are shown. The Challenger L IDU comes
with the standard I/O capability which can be upgraded. In addition, the Modem/IF function is
modular. This allows the addition of a second Modem to support protection or ring architectures. The
power supply is similarly modular.
The major functions of the Challenger L IDU can be summarized as follows:
•I/O Processing – The Challenger L IDU comes with a standard I/O capability that includes
support for up to 16xE1 and 2x100Base-TX user payloads, 2x100Base-TX for SNMP, and voice
orderwire. In addition, option cards for E3, 1xSTM-1 may be added. The Challenger L IDU
architecture is flexible and allows for the addition of other I/O types in the future.

1-11 This manual is provided by WNI Global and its confidentiality is preserved. Without the pre-written consent from WNI Global,
anyone may not disclose, extract, cite or publish any part or all parts of this manual. Version No.: V2.0
•Switch/Framing – The Challenger L IDU includes an Ethernet Switch and a proprietary Framer
that are designed to support 1+1 protection switching, ring architecture routing, and overall
network control functions.
•Network Processor – The Challenger L IDU includes a Network Processor which performs SNMP
and Network Management functions.
•Modem/IF – The Challenger L IDU Modem performs forward-error-correction (FEC)encoding,
PSK/QAM modulation and demodulation, equalization, and FEC decoding functions. The IF chain
provides a 350 MHz carrier and receives 140 or 60 MHz carriers. The multiplexer function is built
into an appliqué that resides in the Modem/IF Module. Two modems can be used for 1+1
protection or ring architectures.
•Power Supply – The Challenger L IDU power supply accepts - 48 Vdc and supplies the
Challenger L IDU and ODU with power. A second redundant power supply may be added as an
optional module.
The Modem Processor and its associated RAM, ROM, and peripherals control the digital and analog
Modem operation. It also provides configuration and control for both the IF and I/O cards. The
Challenger L IDU interfaces with the Challenger L ODU to receive and provide modulated
transmit and receive waveforms.
The 256-QAM Modem performs the modulation and demodulation of the payload/wayside/SNMP
data and forward error correction using advanced modulation and coding techniques. Using all-
digital processing, the 256-QAM Modem uses robust modulation and forward error correction
coding to minimize the number of bit errors and optimize the radio and network performance.
The 256-QAM Modem also scrambles, descrambles and interleaves/deinterleaves the data
stream in accordance with Intelsat standards to ensure modulation efficiency and resilience to
sustained burst errors. The modulation will vary by application, data rate, and frequency
spectrum. The highest order modulation mode supported is 256 Quadrature Amplitude
Modulation (QAM). Table 1-3 summarizes the TCM/convolutional code rates for each modulation
type supported by the Digital Radio.

The Challenger L IDU also provides the physical interface for the user payload and network
management. In transmit mode, the Framer merges user payload (Fast Ethernet) with radio
overhead-encapsulated network management data. This combined data stream is transmitted
without any loss of user bandwidth. In the receive mode, the Framer separates the combined

data stream received from the 256-QAM Modem. The Challenger L IDU supports Scalable
Ethernet data rates, such as 25 or 50 Mbps via the 100BaseT data interface port. The
Challenger L IDU provides network management data on 10 Mbps ports accessible via the
10/100BaseTX port. The Central Processor Unit (CPU) provides the embedded control and
network element functionality of the OAM&P. The CPU also communicates with other functions
within the Challenger L IDU for configuration, control, and status monitoring. The CPU passes
appropriate status information to the Challenger L IDU front panel display.
The power supply converts 48 Vdc to the DC voltage levels required by each component in the
system.
1.6 Consecutive Point Architecture
The consecutive point network architecture is based upon the proven SONET/SDH ring.
Telecommunications service providers traditionally use the SONET/SDH ring architecture to
implement their access networks. A typical SONET/SDH network consists of the service
provider’s Point of Presence (POP) site and several customer sites with fiber optic cables
connecting these sites in a ring configuration (see Figure 1-5). This architecture lets providers
deliver high bandwidth with high availability to their customers.
Figure 1-5. Ring Configuration.
SONET/SDH rings are inherently self-healing. Each ring has both an active path and a standby
path. Network traffic normally uses the active path. Should one section of the ring fail, the network
will switch to the standby path. Switchover occurs in seconds. There may be a brief delay in
service, but no loss of payload, thus maintaining high levels of network availability.

The consecutive point architecture implemented in the Challenger L Digital Radio family is based
on a point-to-point-to-point topology that mimics fiber rings, with broadband wireless links
replacing in-ground fiber cable. A typical consecutive point network consists of a POP and
several customer sites connected using Challenger L units. These units are typically in a building
in an east/west configuration. Using east/west configurations, each unit installed at a customer
site is logically connected to two other units via an over-the-air radio frequency (RF) link to a unit
at an adjacent site.
Each consecutive point network typically starts and ends at a POP. A pattern of wireless links and
in-building connections is repeated at each site until all buildings in the network are connected in
a ring as shown in Figure 1-6.

1.7 Power Management
RF power management is a radio design feature that controls the power level (typically expressed
in dBm) of the RF signal received from a transmitter by a receiver. The traditional goal of power
management is to ensure that the RF signal at a receiver is strong enough to maintain the radio
link under changing weather and link conditions.
Traditional power management techniques such as Constant Transmit Power Control (CTPC)
and Automatic Transmit Power Control (ATPC) transmit at a high power level to overcome the
effects of fading and interference. However, these techniques continue to operate at a higher
power level than needed to maintain the link in clear weather. Because transmit power remains
high when the weather clears, the level of system interference increases.
Radios operating at high transmit power will interfere with other radios, even if the interfering
source is miles away from the victim. High interference levels can degrade signal quality to the
point that wireless radio links become unreliable and network availability suffers. The traditional
solution to system interference is to increase the distance between radios. However, the resulting
sparse deployment model is inappropriate for metropolitan areas.
In response to the need for a high-density deployment model the Challenger L use a unique
power control technique called A
d
TPC. A
d
TPC enables Challenger L units to transmit at the
minimum power level necessary to maintain a link regardless of the prevailing weather and
interference conditions. The Challenger L is designed and manufactured to not exceed the +30
dBm maximum power allowed. The purpose of power management is to minimize transmit power
level when lower power levels are sufficient. A
d
TPC also extends the concept of power
management by controlling not only the power (dBm) of the RF signal, but its quality (signal-to-
noise ratio) as well.
In contrast to ATPC, the A
d
TPC technique dynamically adjusts the output power based on both
the actual strength and quality of the signal. Networked Challenger L units constantly monitor

BER performance under varying interference and climate
conditions. Each Challenger L unit can detect when there is a degradation in the received signal
level of quality and adjust the transmit power level of the far-end Challenger L unit to correct for it.

TPC provides maximum power in periods of heavy interference and fading and minimum power
when conditions are clear. Minimal transmit power reduces potential for co-channel and adjacent
channel interference with other RF devices in the service area, thereby ensuring maximum
frequency re-use. The resulting benefit is that operators are able to deploy more Challenger L
units in a smaller area.
