2.3. ION-B FEATURES
The following lines report a brief summary of ION-B main features:
• multiband 2G, 2.5G, 3G, and 4G compatible: ION-B is completely transparent to
any transmission protocol and modulation format, and it can distribute any 2G,
2.5G, 3G, and 4G wireless standard. In addition, it allows to carry also the WLAN
(802.11b/g) service over the same infrastructure;
• modular configuration for flexible design: by properly setting some parameters like
the amount of RUs and the antenna locations, the ION-B architecture can follow
the environment specific features in order to obtain the most effective radio
coverage of the indoor area. The modularity of the system allows easy
modifications for future growth and increasing traffic;
• easy to install: the intelligent plug & play ION-B system includes an Automatic
Gain Control (AGC), that eliminates system gain variations regardless of optical
loss. This avoids the need for field adjustments, thus reducing design, installation
and optimization time.
• low-power consumption: establishing a “quasi line-of-sight propagation” towards
all mobile phones inside the area, ION-B works with low power levels. Low power
levels have two great advantages: 1) allow mobile phones to work at lower power
levels, thus limiting the radiated emissions and increasing their battery life; 2)
allow a better control of interference effects between adjacent cells.
• central supervision functions: all individual alarms of ION-B system are available
to both local and remote connections. Detailed alarm information is provided by
special software (i.e. by Supervision or Maintenance software tools) running on a
locally connected host, as well as any information about alarm status and alarm
history is available to remote connections via TCP/IP protocols, SNMP agent, or
HTTP servers. This alarm information is visible also by means of LEDs present on
the front panels of both the MU and the RUs;
• multiple-carriers system: there are no restrictions on the number of carriers that
the ION-B can convey. Obviously, the more carriers per service, the less power
per carrier;
• remote power supply: in case mains cannot be used for the Remote Units, ION-B
offers a centralised power supply option, which distributes both a DC low-voltage
(-48V) power and the optical signals through a composite fibre optic/copper cable;
• wide variety of RF passive devices: the connections between the DAS and the
local BTSs are able to be arranged so as to get the best fit for the customers
needs. ION-B equipment provides RF splitters/combiners, cross band couplers,
attenuators, and duplexers for UL/DL paths, thus allowing maximum in design
flexibility;
• high reliability: high MTBF (Mean Time Between Failure).
