2. Introduction
2.1. Purpose
Mobile telephone and public safety systems transmit signals in two directions
between base transceiver station (BTS) and mobile stations (MS) within the signal
coverage area to carry voice and data traffic.
If weak signal transmissions occur within the coverage area because of indoor
applications, topological conditions or distance from the transmitter, extension of the
transmission range can be achieved by means of an optical distributed antenna
system (DAS).
Office buildings, sports arenas, college campuses, industrial parks, and other areas
of high demand require the specialized capacity boost that an optical DAS can
provide to meet increasing customer demands for voice and data.
An optical DAS contains optical Master Units and a sufficient number of Remote
Units to provide the necessary coverage. The number of the Remote Units depends
on the coverage requirements of the DAS. The Remote Units are connected to the
Master Unit with optical links.
The Master Unit is the connection to the Base Transceiver Stations. The
configuration of a Master Unit depends on the number of the Remote Units and the
frequency range.
RF signals are transported to and from the remote units via optical fibers.
2.2. ION-U High Power Remote and Extension Units
The ION-U is an optical fiber based DAS system that efficiently takes the outputs of
multiple Base Transceiver Stations (BTS) sectors and converts those RF signals to
optical to send them over fiber optic cables to remote units to provide coverage in
indoor and outdoor locations. The system supports both low power and high power
remotes units and SISO and MIMO operation.
The ION-U H 19P2 is a high-power multi-operator 1900 MHz band Extension Unit
(EU). It works in conjunction with a Master Unit in the ION-U optical distribution
system and is connected to the main Remote Unit via an extension cable bridge.
The Extension Unit adds an additional band (1900 MHz) to the main Remote Unit
using the same fiber allowing multiple operators to transport signals to the DAS. The
additional service or frequency band provided by the Extension Unit is achieved
without any impact on the installed network.
The compact mechanical design is specifically architected to be mounted inside
poles or next to the main Remote Unit with a minimal visual impact. A shroud is
available to mount the RU and EU in a single protected structure.
