2. Introduction
This chapter provides an overview of the FibeAir IP-20G, Ceragon’s high-
performance edge node product. IP-20G is specially designed for edge/tail
sites, and features a small footprint, high density, and a high degree of
availability.
IP-20G is an integral part of the FibeAir family of high-capacity wireless
backhaul products. Together, the FibeAir family of products provides a wide
variety of backhaul solutions that can be used separately or combined to form
integrated backhaul networks or network segments.
This enables operators to utilize a combination of FibeAir IDUs and radio units
(RFUs) to build networks in which the most appropriate FibeAir product can
be utilized for each node in the network to provide the feature support,
capacity support, frequency range, density, and footprint that is optimized to
meet the needs of that particular node. The FibeAir series “pay-as-you-go”
activation key models further enable operators to build for the future by
adding capacity and functionality over time to meet the needs of network
growth without the need to add additional hardware.

2.1 Product Overview
FibeAir IP-20G is a compact wireless backhaul node that is optimized for tail
and edge/chain nodal deployment, with a small footprint, high density, and a
high degree of availability.
IP-20G includes an advanced feature set for Carrier Ethernet Transport,
including a sophisticated Ethernet services engine, cutting-edge header de-
duplication techniques, frame cut-through, and more.
IP-20G can also include the following optional features:
Multi-carrier package including two radio channels and radio interfaces.
16 x E1 interfaces, with advanced support for TDM services.
Dual-feed power option for power redundancy.
FibeAir IP-20G is built specifically for tail/edge sites deployments. It is based
on the same architecture and technology as FibeAir IP-20N, and supports
essentially the same feature set but in a fixed form-factor and on a scale that is
optimized for tail/edge sites.
The following interfaces are supported:
6 x 1 GE interfaces total
2 x dual mode GE electrical or cascading interfaces (RJ-45)
2 x GE electrical interfaces (RJ-45)
2x GE optical interfaces (SFP)
Optional: 16 x E1 interfaces
Single or dual radio interfaces (TNC)
Single or dual power-feeds (-48v)
Sync in/out interface
Management interfaces
Terminal –RS232 (RJ-45)
2x FE electrical interfaces (RJ-45)
External alarms interface
FibeAir IP-20G is based on a passive cooling design that does not require fans,
for improved operational efficiency.
IP-20G enables operators to maximize QoE with an improved customer
experience by providing TCP-friendly backhaul. The system provides support
for emerging services, standards, and networking protocols (future proof). It
also enables operators to reduce TCO by supporting rich, revenue-generating
services, simplified management for reduced OPEX, and improved service
availability and time-to-revenue.
IP-20G provides an innovative packet backhaul services aggregation solution
that is designed to meet the challenges faced by operators building next-
generation wireless backhaul networks for delivery of packet-based services.
Meeting these challenges requires the ability to maintain services with strict
SLA by enforcing a services policy that guarantees and monitors service
performance. It also requires the ability to manage the explosion of data by
ensuring capacity allocation and traffic management under wireless link
congestion scenarios.

IP-20G maintains high capacity at the aggregation network, with modulation
of up to 1024 QAM. The IP-20G aggregation solution is based upon rich
backhaul services and simplified management that are supported using
personalized QoS (H-QoS), superb service OAM (CFM, PMs, service activation),
and carrier-grade service resiliency (G.8032, MSTP).
2.1.1 IP-20G Radio Options
An IP-20G system consists of an IP-20N indoor unit (IDU) and either one or
two of the following radio frequency units (RFUs).
2.1.1.1 RFU-C
FibeAir RFU-C is a fully software configurable, state-of-the-art RFU that
supports a broad range of interfaces and capacities from 10 Mbps up to 500
Mbps. RFU-C operates in the frequency range of 6-42 GHz.
RFU-C supports low to high capacities for traditional voice and Ethernet
services, as well as PDH/SDH or hybrid Ethernet and TDM interfaces. Traffic
capacity throughput and spectral efficiency are optimized with the desired
channel bandwidth. For maximum user choice flexibility, channel bandwidths
can be selected. RFU-Ce provides a range of modulations from QPSK to 1024
QAM.
When RFU-C operates in co-channel dual polarization (CCDP) mode using
XPIC, two carrier signals can be transmitted over a single channel, using
vertical and horizontal polarization. This enables double capacity in the same
spectrum bandwidth.

2.1.1.2 1500HP/RFU-HP
FibeAir 1500HP and RFU-HP are high transmit power RFUs designed for long
haul applications with multiple carrier traffic. Together with their unique
branching design, 1500HP and RFU-HP can chain up to five carriers per single
antenna port and 10 carriers for dual port, making them ideal for Trunk or
Multi Carrier applications. The 1500HP and RFU-HP can be installed in either
indoor or outdoor configurations. The 1500HP and RFU-HP also include a
power-saving feature (“green mode”) that enables the microwave system to
automatically detect when link conditions allow it to use less power.
1500HP/RFU-HP provide a range of modulations from QPSK to 1024 QAM.

Specifically built to support resilient and adaptive multi-carrier radio links,
scaling to GE capacity
Future-proof with maximal investment protection
Supports RFU-Ce and RFU-HP for modulations up to 1024QAM.
2.1.3 IP-20G Protection Options
IP-20G provides 1+1 HSB radio protection. In dual-carrier systems, the user
can configure the two radio interfaces as a protection group, which protects
against hardware failure in the RFU. The CPU monitors the radio interfaces
and initiates switchover upon indication of a hardware or signal failure.
A power redundancy option is also offered by means of a dual-feed power
input hardware assembly option.
