2 9341 RRH40-21 SOLUTION OVERVIEW

2.1 Overview

The Alcatel-Lucent distributed solution is composed of two main parts:

• The Alcatel-Lucent digital Node B

• The Alcatel-Lucent 9341 RRH40-21, located on the remote site: 9341 RRH40-21 provides the RF transceiver, MCPA and filter functions typically found in the

conventional Node B.

Figure 1 – Alcatel-Lucent 9341 RRH 40W 2100MHz

(without and with solar shield)





These two equipments are linked by optical fibres, carrying UMTS downlink and uplink (main

and diversity) base band digital signals along with OAM information.

Figure 2 – 9341 RRH40-21 System Overview

(Star Configuration Supported From 9326 d2U Node B)

2.2 Product Positioning

Alcatel-Lucent distributed solution is designed to provide operators with the means to achieve

a high quality and capacity coverage with minimum site requirements.

9341 RRH40-21 is designed for macro-cellular applications, and is an alternative to

conventional Macro Node B.

The advantages of using Alcatel-Lucent 9341 RRH40-21 to replace a traditional Node B are

most evident in rooftop installations. In fact, the limited space available in some sites may

either prevent the installation of traditional Macro Node B equipment or require costly cranes

to be employed, thus coverage holes may appear. These sites can however host 9341 RRH40-

21 installation providing more flexible site selection and therefore improved network quality.

In addition installation times and costs are greatly reduced.

Figure 3 - Site Benefits of Deploying 9341 RRH40-21

2.3 Benefits of 9341 RRH40-21

In comparison with a traditional Node B site, the following benefits are achieved:

2.3.1 Higher Savings On Remote Sites

Faster and lower cost implementation:

• Due to its small size and weight, operators can locate the 9341 RRH40-21 where RF

engineering deems ideal, trade-offs between available sites and RF optimum sites are

minimized

• 9341 RRH40-21 is a zero footprint solution and a noise-free module: this allows for

simpler negotiation with site landlords and minimize the impact on the

environment/neighbourhood

• Less civil works are required. There is no need for reinforcing steel frames to support

heavy outdoor Node B cabinet (around 300Kg). 9341 RRH40-21 weighs less than 20kg.

• 9341 RRH40-21 is an easy-to-install product (sizes below 30l): the installation can be

done by a single person, no cranes are needed to hoist the Node B cabinet to the

rooftop.

• A site can be on air in < one day, a fraction of the time required for a traditional Node

B.

Less rental area:

• The footprint of a cluster of 9341 RRH40-21 is much less than the footprint of a

traditional Node B cabinet (in some cases also transmission cabinet, battery cabinet

and power distribution cabinet) therefore the monthly rental fees are considerably

reduced (less footprint and weight).

Less equipment on site:

• The digital Node B cabinet does not need to be installed on the rooftop and can be

placed in the basement (with fibre running to 9341 RRH40-21 in rooftop) or in

centralized Node B “hotels” (if dark fibre is available between sites).

• No need for TMAs due to the fact that the feeder losses are dramatically reduced (9341

RRH40-21 are mounted close to antennas)

Great RF performance thanks to the capability of installing 9341 RRH40-21 close to the

antenna:

• No RF feeders are needed, only jumpers from 9341 RRH40-21 to the antenna. This

reduces the feeder loss in UL/DL, having several consequences:

− The feeder cost and installation costs are reduced.

− In the UL, there is no need for a TMA, as the losses introduced by the RF feeder are

greatly reduced.

− In the DL, no RF power is dissipated in the feeder runs. The PA power can be

reduced while maintaining the same RF power at the antenna. This results in the

power consumption of the equipment being reduced. Compared to a conventional

Node B (equipped with MCPA 60W) that delivers about 20W at the antenna level

(assuming 3dB feeder+TMA losses), 9341 RRH40-21 (assuming 0.8 dB jumper loss)

delivers 65% more RF power while consuming half the power.

2.3.2 Reduced CAPEX and OPEX

2.3.2.1 Reduced CAPEX

• Where dark fibre is available, Node Bs can be centralized (Node B hotels) off-town,

thus further reducing the site construction/ acquisition cost, normally higher in urban

areas: cost is further decreased by the use of one single fibre (thanks to single-mode

CWDM feature) per remote site (assuming daisy-chain), leading to a dark fibre lease

cost reduction factor of up to 6.

• A digital Node B can serve several remote sites and Channel Element pooling amongst

them further reduces equipment costs.

2.3.2.2 Reduced OPEX

• Up to 50% reduction in power consumption.

• 20% less site visits: as the Channel Element cards are in the digital Node B cabinet,

there is no need to visit the remote site for capacity upgrades.

• 9341 RRH40-21 has a high MTBF and uses natural convection cooling to produce a zero

noise high reliability fan-less solution.

• Operation and management is simplified as number of Node Bs that need to be

managed is reduced (one digital Node B can serve several remote sites) and they are in

the same location.

• Transmission costs are reduced as no leased E1/T1 is needed, instead owned and/or

leased optical fibre between 9341 RRH40-21 site and centralized base station.





3 9341 RRH40-21 PRODUCT DESCRIPTION

3.1 Overview

9341 RRH40-21 is a single sector 2100 MHz (3GPP band I) self-contained radio module,

including:

• A 2100 MHz transceiver

• An MCPA

• A duplexing system

• An optical interface

• A power system

9341 RRH40-21 delivers 40W nominal composite RF power at antenna port and supports up to

3 carriers.

It is an outdoor product, supporting -40°C/+50°C temperature range (up to +55°C with de-

In downlink, 9341 RRH40-21 receives the optical signal from the digital Node B in accordance with CPRI format. The signal is converted into an electrical digital base band signal, which

goes then through several digital processing functions (filtering, digital up-conversion, peak

power reduction, digital pre-distortion). The resulting digital signal is digital to analogue

converted and up converted to an RF signal. The RF signal is amplified through a power

amplifier and fed to the duplexer. 9341 RRH40-21 measures continuously the transmit RF

power and has the capability to monitor VSWR.

In uplink, two signals are received from the main and diversity antennas. They are amplified, through low noise amplification chains, and down-converted before being converted into

digital signals. The resulting digital signals go through different digital processing functions

(digital down-conversion, filtering), and are then multiplexed according to the required CPRI

format and converted into optical signals that are sent to the digital Node B.

9341 RRH40-21 has two antenna ports: one port is connected to a duplexer, which provides

the necessary isolation to connect the transmitter and one receiver on the same antenna. The

second 9341 RRH40-21 port enables RX diversity. 9341 RRH40-21 also provides a TX coupling

port for on-field test purpose.

The digital Base-Band processing provides daisy-chain capabilities to link several 9341 RRH40-

21 with only one fibre link coming from the digital Node B.

9341 RRH40-21 is offered in 2 variants, according to optical interface (Single-Mode or Multi-

Mode optical fibre).

4.2 Evolution Path

The following sections describe the architecture impacts on 9341 RRH40-21 solution: some are

related to upgrade while others are related to new 9341 RRH40-21 topology configurations:

• Increase the number of RF carriers

• Daisy-chain feature

• TX diversity





4.2.1 Multi-Carrier Configuration

4.2.1.1 Single 9341 RRH40-21 per sector: STSR2 & STSR3

The configuration and topology of a 1 carrier site remains the same when adding the second

carrier: upgrade is performed via software.

Figure 9 – 9341 RRH40-21 in 2 Carriers Configuration

Same applies for upgrade from 2 carriers (STSR2) to 3 carriers (STSR3) configurations.

4.2.1.2 Two 9341 RRH40-21 per sector: STSRx+y

9341 RRH40-21 is provided with a specific feature that makes it possible to manage up to 4

carriers on the UL (each 9341 RRH40-21 manages one single RX antenna), more precisely two

blocks of adjacent carriers. By using two 9341 RRH40-21 per sector, the following STSRX+Y

configurations may be supported in the future:

• STSR1+1, providing 40W per carrier

• STSR2+1, ie 3 carriers configuration providing 20W per carrier

• STSR2+2, ie 4 carriers configuration providing 20W per carrier

STSRX+Y configurations using 9341 RRH40-21 are perfectly suited to support UTRAN sharing.

4.2.2 Daisy-Chain Evolution

In the future, up to three 9341 RRH40-21 (up to six in single carrier configuration) may be

daisy-chained on the remote site linked to the Digital Node B by a single optical fibre link.

This feature will be an enabler for deployment using long-distance fibre run, as it will

minimize the number of dark fibres required, translating into operator CAPEX and OPEX

savings.

Figure 11 – 9341 RRH40-21 in Daisy-Chain Configuration

4.2.3 Tx Diversity Evolution

Tx diversity (future) will require the co-location of a second 9341 RRH40-21 per sector.

Using the daisy-chain feature, an additional short range fibre link will be required between

two co-located 9341 RRH40-21.

As an alternative site solution, the second 9341 RRH40-21 can be connected using a direct

fibre connection to the digital Node B (6 fibres from digital Node B).
