1 Introduction

The evolution of the Small Cell architecture and the need to deploy Pico sites at the
street level, create new challenges of deploying wireless backhaul links in Non-Line-of-
Sight (NLOS) conditions. In NLOS conditions, the signal propagation is blocked by street
obstacles (e.g. buildings, furniture, poles, trees, hills) and propagates in use cases of
diffractions, reflections or penetrations. The received signal is a superposition of multi
paths and there is a very wide variance of the received signal strength and its
distortions.

Deploying backhaul system in NLOS conditions is a new challenge due to the need to
bridge between the inherent uncertainties in the NLOS propagation conditions from
one side and the strict requirements of the Mobile Operators to get a Carrier-Grade
solution from the other side.

Addressing this challenge requires innovative technologies to resolve the following:
 Provide the required capacity for today and tomorrow needs.
 Comply with the KPIs for service availability, latency, jitter and quality of services
 Meet street level requirements such as small form factor and low power
 Provide ease of installation, operation and maintenance
 Provide simple means for planning at certainty level that enables to engage in site
acquisition
 Provide simple, accurate and low costs solution for site survey and installation in
NLOS conditions
 Maintain the backhaul performance and meet the required KPIs in a dynamic
changes environment at the street level

Addressing these challenges is essential to provide the required performance and the
operational viability to make
NLOS backhaul deployment a wide scale solution for Small Cell application.

One of ALCATEL-LUCENT's dedicated tools for addressing NLOS challenges, is the Smart
Beam Forming Antenna:

It assures very high performance and flexibility in the system deployment - it
increases the system gain, enables higher order of MIMO (3X3), simplifies the
installation by implementing automatic antenna alignment, and it supports
Interference Rejection by aligning the antenna pattern.

ALCATEL-LUCENT's Smart Beam Forming Antenna (SBFA) also supports Advanced

Antenna Steering mechanism which automatically steers the antenna in the best
direction and thus, the link achieves best performance (such as throughput and
latency). Moreover, the Advanced Antenna Steering mechanism allows interference
cancellation. This mechanism has significant impact on the efficient use of the
spectrum, the optimization of service quality, higher capacity and improved
robustness.

In this document we describe how ALCATEL-LUCENT addresses these challenges with
a set of innovative technologies incorporated in the products portfolio successfully
responding to the operational needs of planning, installation and maintenance.

The document provides a comprehensive description of ALCATEL-LUCENT’s SCBH
systems: Architecture, Supported Bands & Regulations, System Description, Innovative
Technologies & Features and Concept.

2 Concept

The MPT-SUB6 introduces a NLOS backhaul solution that supports a net throughput of up
to 350Mbps in a single 40MHz channel.

The product’s high quality performance in NLOS conditions is achieved by two layers in
the radio:

 MIMO / OFDM based PHY
 Proprietary advanced & robust Air Interface

The core competence of the air-interface is its dynamic adaptation, in a resolution of
frame by frame, to the instantaneous changes in the link conditions optimizing the
system performance to achieve maximum and stable capacity along with minimum
latency.

In addition, the MPT-SUB6 introduces a Smart Beam Forming Antenna which
enables the following capabilities:

 Increases system gain
 MIMO 3x3
 Beam forming
 Multipath aggregation
 Interference cancellation by aligning the Smart Beam Forming antenna patterns
 Automatic alignment

Beam Forming and Interference Cancellation mechanisms are operative during antenna

alignment. The radio finds the best path for the two spatial streams along with a
shaped pattern in order to overcome any
existing interference and thus achieve the best link performance.
It simplifies operation and removes the dependency on installation skills and accuracy
as installation is automatic. The air-interface controls the Modem and the Smart Beam
Forming Antenna and adopts them in accordance with
the dynamic changes in the channels.

As an example, the air interface adopts the MIMO mode, the Modulation Coding
Scheme (MCS), Guard time Interval and configures the antenna-phase-weight shaping
the antenna patterns in order to maximize the system gain.

Their combined contributions are essential to overcome the NLOS deployment challenges.

The MPT-SUB6 radio is optimized for urban NLOS backhaul of small cells.
2.1 Planning & Operating under NLOS conditions

The MPT-SUB6 addresses the challenges of planning and operating under NLOS
conditions in two main aspects:

1. By offering robust NLOS Backhaul radio solutions which are capable of
mitigating the harsh installations environment and adapt to the rapid urban
changes: Multipath and interferences
2. By providing deterministic prediction tools for the RF planning, allowing the
service provider to minimize the risks involved in mass deployment in the urban
environment.

Planning a PtP link and PtMP sector under NLOS conditions is achieved with
ALCATEL-LUCENT's unique NLOS planning solutions:
 Fully automatic
 Customized for ALCATEL-LUCENT’s proprietary technology
 Accurate Service performance calculations and SLA based on wave propagation
and ALCATEL-LUCENT System’s specific characteristics and topology (Band, PtP,
PtMP)
 Providing tools for qualifying BH sites
 Optimal automatic association between Small-Cells and Donors/Aggregation
points based on System topology, service requirements and SLA
The initial planning is exported as a work order to support the next step – an
efficient and fast site survey. With ALCATEL-LUCENT 's unique Site-Survey tool,
information is collected, validated and then fed into ALCATEL-LUCENT 's RF
Planning tool to allow composing the final Planning Report.

Manual
7 / 60
Thus, the final Planning Report provides deterministic prediction and reliable plan for
the NLOS Backhaul system deployment.
2.2 The Alcatel-Lucent Survey Kit:

The Site Survey kit is used as an integral part of the planning and prediction process
for NLOS small cell backhaul deployment at the street level. The installer carries out a
site survey based on site information obtained from the ALCATEL-LUCENT planning
tool.

The kit is designed to make the survey process accurate, smooth and rapid. It is
intended for use at sites to be operated in the 3.xGHz or 5.xGHz bands.

The kit includes the MPT-SUB6 radio with an integrated Smart Beam Forming Antenna
and an extendable battery pack (no need for an external power supply!).

The kit also includes a tablet with an embedded dedicated management & survey
application. The application provides for easy performance evaluation: spectrum
analysis and link performance monitoring & recording.

The kit is offered in four versions: FCC and ETSI for 5.xGHz and 3.xGHz. The kit
provides for one side of a surveyed link.
2.3 The MPT-SUB6 - PtMP Solution:

The MPT-SUB6 consists of an HBS sector radio and up to four remote radios (High
Capacity SUs – HSUs). The MPT-SUB6 radio employs a TDMA technology and it
supports a sector throughput of up to 350Mbps net aggregate traffic at 40MHz
channel BW.

Allocation of sector traffic is carried out as follows:

1. The user configures the minimum number of time slots to support the required
SLA service (Assured Throughput)
2. ALCATEL-LUCENT's DBA (Dynamic Bandwidth Allocation) increases the actual
throughput by allocating unused time slots of inactive radios
3. ALCATEL-LUCENT 's unique DBA algorithm guarantees that service will not suffer
degradation when other radios in the sector suffer decline of link properties.
2.4 The MPT-SUB6 - PtP Solution:

A PtP architecture is established using the same HBS sector radio remote radio (HSU)
listed above in the PtMP
solution. PtP connectivity is achieved thanks to the following features:

Manual

1. ALCATEL-LUCENT's management applications allow allocating the entire
sector capacity (time slots) to a single remote radio (HSU)
2. ALCATEL-LUCENT's Smart beam Forming Antennas at both ends shape the
radiated pattern automatically to provide directional PtP link

The MPT-SUB6 can be managed locally and remotely via EMS (Manager), and can
be integrated with the ALCATEL-LUCENT 5620 SAM.
