INOVA DAS Bluetooth Manual

MHU is connected to the base station with wired RF cable, and connected to the lower EHUB

equipment with optic cable. EHUB is connected to ERU with wired Cat.7 cable, optic signal is converted

into Ethernet signal and transmitted to ERU or the Ethernet signal is converted into optic signal and

transmitted to MHU. Each branch of the MHU can each be connected cascade with 2 EHUBs for

operation, EHUB can be connected up to total of 4 ERUs.

Used Abbreviations

MHU: Master Hub Unit

DAS: Distributed Antenna System

EHUB: Ethernet HUB unit

ERU: Ethernet Remote Unit

ERFU: ERU RF Unit

The EHUB has no other transmitters except for Bluetooth transmitter. The ERU has Bluetooth

Bluetooth transmitter into EHUB and ERU device is just operated for status monitoring and control

parameters from server, software for DAS download and signal quality measurement.

There is no simultaneous transmission between Bluetooth transmitter and the repeater modules

within ERU device because ‘the cellular repeater signal on downlink side is NOT transmitted through

Bluetooth transmitter’.

The Bluetooth specification is as follows.

- Bluetooth V 2.0 / Class 1

- Output power: 5 dBm

- Size: 27.1 X 14.8 X 2.6mm (Shield case)

- Operating Temperature: -40°c ~ +85°c
