1–1.2 General description
The 9400 AWY is a family of digital Point to Point microwave radio systems designed to satisfy the various
digital transmission needs of public and private networks for a large range of applications.
The short–haul microwave systems are particularly recommended for the interconnections of cellular
networks base stations and base station controllers.
They can also be used for the rollout of public and private networks, in urban or suburban regions and by
means of the Ethernet interfaces they provide a wireless solution in the access area for data connectivity
as 2G/2.5G/3G networks, cellular LMDS/WIP networks and digital terminal connection (PABX,
Videoconference, etc.).
The 9400 AWY represents an attractive solution for the above needs due to radio intrinsic characteristics
as:
–easy and fast deployment
–effective solution in difficult geographical area
–very low cost of the complete network
–security against physical damages
–reuse of existing frequency plan
–progressive capital investment according to traffic needs
The 9400 AWY is a complete homogeneous family of PDH Point to Point low and medium capacity
microwave link, fully integrated in the last SDH 9600 LSY and 9600 USY families for world wide
applications in all frequency bands from 13 GHz to 38 GHz.

1–1.3 Network applications
1–1.3.1 Cellular backhaul applications
A major application is related to cellular networks, mainly in urban and sub–urban areas where an
increasing number of small cells are used to densify the network, leading to a need for a very high number
of radio links inter–connections in the millimeter wave frequencies (23 to 38 GHz) which are well suited
for short distances and allow to take advantage of increased frequency reuse.

wireless networks
•9400 AWY is used in networks which are similar to the standard private networks/business
applications of microwave radios:
In very dense area the 9400AWY can be combined with Alcatel LMDS family to provide integrated
access solutions.
The 9400 AWY product provide NxE1/NxDS1 direct connections (leased lines applications) of
subscribers to avoid to congest the LMDS spectrum in one sector or the connection of subscribers
who are out of range with the LMDS cell but whose traffic does not justify the installation of a new
cell.
•9400 AWY is used to provide E3/DS3 inter–connections between Wireless IP base stations or
between regional low traffic potential LMDS base stations, in order to provide a cost effective
infrastructure transmission solution.

–Indoor Unit (IDU)refer to paragraph 1–1.5.1 on page 26
–Outdoor Unit (ODU)refer to paragraph 1–1.5.2 on page 30
–IDU/ODU cablerefer to paragraph 1–1.5.3 on page 29
IDU and ODU are connected with a single standard coaxial cable carrying the main traffic, the remote
power supply voltage for the ODU and auxiliary information.
Rack or wall or desk mounting are available for the IDU.
The ODU can be installed on standard poles, wall or pedestal mount, with an appropriate fastening
system, which guarantees the coarse and fine pointing, even when a faulty ODU has to be replaced.
document, use and communication of its contents
All rights reserved. Passing on and copying of this
not permitted without written authorization from Alcatel.
The ODU (one or two depending on the configuration 1+0 or 1+1) incorporates the complete RF
transceiver and can be associated with an integrated antenna (30 cm or 60 cm diameter) or separate
antenna, if a larger diameter is needed. The ODU is capacity–independent and consists of a single cabinet
(size and weight independent on frequency) with a solar shield.
The cabinet is a very compact and robust weatherproof (IP 67) container, designed to be compatible with
hot and very sunny climatic zones.
The ODU can be rapidly installed on standard poles with an appropriate fastening system. The pole
mounting is the same for 1+0 or 1+1 configurations from 13 to 38 GHz.
The ODU is fixed by means of quick latches. This system allows to change the ODU without altering
antenna pointing
The pointing of the antenna can be easily performed with the use of a dedicated service kit. This kit, when
connected to the ODU, provides the received signal level, and the connection to the other station on the link
through a telephone service channel.

operates from 13 GHz to 38 GHz. The mechanical structure utilizes an outdoor water–resistant IP67
cabinet (see chapter 2–3 on page 73 for drawings).
The mechanical solution is the same for the 13 to 38 GHz frequency bands, while the only differences
among the frequency bands are related to the diplexer and the RF section.
All configurations are available for each frequency band.
The ODU presents one output port at which a single polarization integrated antenna (30 cm or 60
cm diameter) or a waveguide for not integrated antenna connection can be connected.
The ODU is capacity–independent.
The ODU consists of subunits which carry out the following main functions (see Fig. 7. on page 30):

signals and harmonics. It consists of two band–pass filters: one for the Rx and one for the Tx.
The rejection between these two parts is more than 70 dB. The insertion losses are less than
2 dB.
b )Solar shield
Even if the ODU has been designed to work without solar shield, this one is always delivered with
each ODU.
N.B.Note : the ODU is qualified for a room temperature of +55
ED
03
: it is screwed on the Front End box
: it is inserted between the front end and the antenna. Its scope is to filter all interfering
0
C maximum. In case of solar
radiation (1120 W/m2), the maximum room temperature is reduced to +40
0
C (ETS 300
019–2–4.1). It assumes that the protection of the solar shield is 15 0C.

c )ODU Coupler
The ODU coupler (shown in Fig. 23. on page 86) is used in the following equipment configuration:
•1+1 HSB
•1+1 FD CP
The 1+0 configuration is comprised of a simple diplexer inside the cabinet while the protected
configurations (1+1) are always comprised of two cabinets and:
•one 3 dB symmetric or 1/10 dB asymmetric coupler for HSB configuration
•one 3 dB symmetric coupler for FD with single polar antenna
The couplers are connected between the cabinets and the antenna.
1–1.5.3 IDU–ODU cable
The connection between the IDU and the ODU is realized with a single coaxial cable and N–50 ohm
connectors.
On this cable the following signals are present:
–DC voltage to the remote power supply of the ODU;
–HDB3 Tx signal;
–HDB3 Rx signal.
The HDB3 signal is an aggregate signal including the main signal, auxiliary signal and the IDU–ODU
service channels.
The bit rate of the aggregate signal is listed in the following table.
