ION™-M Series
ION-M Series is a robust high power-density fiber-based distributed antenna
system (FDAS) with Radio over Fiber technology) that offers outstanding performance
in both indoor and outdoor environments. Typical applications range from coverage
of the central business districts to underground, rail, tunnel, and high rise
coverage.
Features of the ION-M Series
- Bidirectional amplification of signals between multiple mobiles
and the base station
- Standard WDM (single fiber that transports UL and DL) and optional
optical splitting to support up to 4 remote-units from a single master
unit OTRx
- Configurable for point-to-point, point-to-multipoint, and network
redundancy
- System transports multiple carriers, multiple technologies, and
multiple frequencies simultaneously. Supporting single-band, multi-band
and even multi-sector remote units
- Multiple extension option for field upgrade to additional frequency
bands or additional sectors
- Wide bandwidth - 380 to 2700 MHz
- 802.11 WLAN and 802.16 WiMAX compatible
- Centralized and flexible radio network interface
- Compact, sealed remote units rated to IP67 require no additional
housing or special treatment for outdoor use
- Alarming via different means: SMNP interfaces for X.733, SMS, or
dry contact alarming
- Full integration into Andrews standard OMC A.I.M.O.S with data
backhaul circuit switch or packet data connections

Components
- Master Unit:
- Interfaces to the base station via RF cables, to remote units
via optical fiber, and to the network management (A.I.M.O.S.)
via a wireless modem, wireline modem or LAN connection
- Modular to support any configuration up to 124 optical links
to remote units
- Easily changed from single-band/single-user system
to multi-band/multi-user
- miniMaster plus:
For smaller installations, the MMC plus controller unit is a tailored
cost- and space- optimized solution when sophisticated control and
supervision functions are not required. The MMC plus controller provides
up to three optical interfaces as well as one power supply in a single
three HU (height unit) 19-inch rack. Up to three subracks with integrated
power supply can be added
- Remote Units:
- ION™-M remote units are available in single- or multi-band
and micro or macro RF power classes. Guaranteeing a safe investment,
all single- and multi-band units can be extended in the field to
handle additional frequency bands and services. Highefficiency
MCPA technology empowers the remote units for multi-carrier and
multi-user applications. The remote units support WLAN (wireless
local area network) and WiMAX (worldwide interoperability for microwave
access) services through a transparent channel, while optional test
heads monitor antenna signals and deliver reliable performance data
in neutral host scenarios
Options
UPS - Uninterruptible Power Supply provides high quality
AC power for electronic equipment loads, especially for outside repeater
systems to give continuity of electrical power for at least 20 minutes
up to 8 hours when commercial AC source fails or degrades from overload,
surges, or spikes.
- BBU - Battery Backup Unit is used in the master unit
to operate the controller and the modem for 10 minutes up to 8 hours to
maintain control over the system and proceed problem root-cause finding
even when the master site power is down.
- Redundancy - Various redundancy options from
redundant power supply to power amplifier and optical modules to full
redundant systems with 2 remote units and 2 fiber links running in redundancy
configuration.
- CPD - Channel Power Detector is a test-head inside
the remote unit that give exact downlink power per band and channel (rms)
measured directly at the antenna port – It includes also VSWR measurement.
Alarming is possible on VSWR and downlink power high and low levels.
- UMR - Universal Measurement Receiver
is a test-head inside the remote unit that give exact downlink power (RSSI)
per band and channel, Ec/No, pilot-power and pilot and signalling decoding
for AMPS, CDMA, GSM, DCS, UMTS, WiMAX. The measurements are for downlink
and uplink and it provides also traffic statistics in uplink. It includes
also VSWR measurement. Alarming is possible on VSWR and downlink power
high and low levels.
- CSO - Cable Supervision Option is used in systems that
feed radiating cable. It injects a pilot signal at the output of a remote
unit and checks whether this pilot is received on the other side of the cable
at the input of the next remote-unit. By this its easy to detect a lose of
broken cable.
ION™-M Application Examples:

The ION™-Ms available performance margin, the optical link budget, and
the system flexibility allows to built up various network configurations.
Regarding the link between master unit and remote unit, it is possible
to configure the system according to the following methods:
- Point-to-point connection
- Star configuration
- Daisy-chain configuration
A sector (BTS/Node B port) can be assigned to a single remote unit, a
single optical link (maximum four remote units), or multiple remote units.
The criteria for the number of remote units assigned to a sector, is mainly
determined by the maximum raise of noise power acceptable at the BTS/Node
B.
Because of MCPA (multi-carrier power amplifier) technology, the ION™-M
series is ideally suited for multi-carrier (multi-user) wide-band applications.
But it also supports high reliability networks such as GSM-R or TETRA with
multiple redundancy scenarios on equipment or network level.
