Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut

fonctionneravec une antenne d’un type et d’un gain maximal (ou inférieur) approuvé pour l’émetteur par Industrie Canada.

Dans le but de réduire les risques de brouillage radioélectrique à l’intention desautres utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la puissance isotroperayonnée quivalente (p.i.r.e.) ne dépassepas l’intensité nécessaire à l’établissement d’une communication satisfaisante.

2.2 System Network Configuration

INOVA DAS basic network configuration and optical extend configuration is as below picture.

Figure 1. Basic Network Configuration.

The MHU is connected to the base station with RF cable, and the lower ROU equipment is connected

with optic cable. Each branch of the MHU can be operated by cascade connection with each 8 ROUs,

and 1 MHU can connect up to 48 ROUs.

For service extension, extended ROU is connected by optic cable with Single ROU(Main), one branch

can operate up to 8 ROUs, so up to 4 stages of cascade is available for extend configuration.

“ This manual is to provide product installation method and product information to the user operating

the INOVA DAS system, the repeater manager who uses the operation manual needs to require

professional knowledge and experience on construction operation of repeater systems. “

This chapter explains how to connect power cables and how to install each equipment and optic

cable. It specifically describes MHU(MWDM, MPSU, MDRU, MBIU), ROU 2W, ROU 5W installation

method and cable connecting method.

5.2.1 Product Installation

MHU is configured with MWDM, MPSU, MDRU, MBIU, all units are designed as 19" rack type.

According to cable configuration, installation must be made in the order of MWDM, MPSU, MDRU,

MBIU, and it is recommended to slightly open between each unit when installing.

Page 49

INOVA DAS Operating Manual

Recommendation

When installing MPSU, MDRU, and MBIU to 19" rack, it is recommended to install them ar 1U

intervals.

Figure 15. Within 19” Rack, MHU installation.

Align the MHU(MWDM, MPSU, MDRU, MBIU) to rack installation location, when installation location

is confirmed, use fixing screws to fix MHU to rack. For fixing screws use M6*12L bolt to fix.

Figure 16. MHU Cable Connection.

Above figure shows cable connection of MHU. MWDM and MDRU are connected with optic cable,

MWDM and ROU are connected by optic cable. MPSU supplies power to MDRU and MBIU through

harness, MDRU and MBIU are connected between harness and RF cable. MBIU basically operates with

single so cable is configured as the center figure, however if additional Extend MBIU is installed, one

additional MBIU is configured to the existing MHU and additional cable is connected, just like the right

side figure.

Caution

When installing MHU, make sure that the power switch and distribution board switch on the front

of the MPSU are OFF before proceeding.
