1. Introducing ION-B

1.1 The Features

ION-B is an innovative platform designed in order to provide an effective and ﬂ exible

coverage to a large variety of indoor scenarios.

Thanks to its high modularity, its low power consumption, and its full-transparency to protocols

and modulation formats, ION-B is the perfect plug&play solution to distribute any wireless

standard (including GSM, GPRS, EDGE, CDMA, W-CDMA, and WLAN IEEE 802.11b/g) to the in-

building environments requiring reliable and interference-free communications, as well as high

trafﬁ c capacity and maximum ﬂ exibility about future expansions.

These unique features make the ION-B platform suitable also for applications to critical areas

experiencing difﬁ culties in establishing and keeping phone calls, while its compact design

always guarantees a minimum aesthetic impact.

1.2 Brief Description of ION-B

ION-B is a Distributed Antenna System (DAS) based on the Radio-over-Fibre (RoF) technology,

and capable of carrying wireless mobile signals through the 800MHz - 2500MHz frequency

range regardless of their protocol and their modulation format.

The system has two basic components, a Master Unit and a Remote Unit. The Master Unit

is made of one or more subracks typically connected to the BTS (Base Tranceiver Station)

through either a repeater (RF interface) or a coaxial cable.

Each Remote Unit is connected with a dedicated pair of single-mode optical ﬁ bres (one for

UL and one for DL) to the Master Unit. These optical ﬁ bres work on 1310 nm wavelenght and

provide low losses and almost unlimited bandwidth, available for future system developments.

ION-B is a modular system whose basic components are:

• one Master Unit made of one or more subracks, each providing 12 module slots. Each

slot can host either an active or a RF passive device (chosen among the wide range of ION-B

options), in order to meet the planned design requirements;
