2. GENERAL INTRODUCTION OF ION-B PRODUCTS
2.1. THE FEATURES
ION-B is an innovative platform designed in order to provide an effective and flexible
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 LTE to the in-building environments requiring reliable and interference-free
communications, as well as high traffic capacity and maximum flexibility about future
expansions.
These unique features make the ION-B platform suitable also for applications to
critical areas experiencing difficulties in establishing and keeping phone calls, while
its compact design always guarantees a minimum aesthetic impact.
2.2. 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 700MHz -
2700MHz 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
Transceiver Station) through either a repeater (RF interface) or a coaxial cable.
Each Remote Unit is connected with a dedicated pair of single-mode optical fibres
(one for UL and one for DL) to the Master Unit. These optical fibres work on 1310 nm
wavelength and provide low losses and almost unlimited bandwidth, available for
future system developments.
ION-B System Block Diagram
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;
• a variable number of Remote Units (TFAx), whose function is feeding the antenna
passive network;
• a proper number of indoor antennas, suitable to provide radio coverage to the
area. ION-B is fully compatible with any type of indoor antennas;
• the optical cables required to connect the 19” subracks to the TFAx.
