2.2 Radio Interface Unit (RIU)
The RIU is an operator dedicated unit that interfaces to up to three BTS sources and
automatically adjusts the signal output according to changing environmental conditions in order
to provide optimal coverage for the site. The RIU is remotely monitored and managed.
Each RIU can support up to three BTS Conditioner (BTSC) sub-modules, where each sub-
module provides interface to a BTS or BDA of
the same type of service
.
Each RIU can be connected to
four
8-port Base Units (real panel connections) or to
eight
4-port
Base Units.
Additional BUs can be supported by using splitters and combiners connected to the front panel
Expansion connectors.
The following figures shows an RIU with three BTSC sub-modules.
Figure 2-11. RIU
Note: All connections are via RG223 coax cables with 1/2" N-type male connectors
ATTENTION
The RIU is factory set to 0dB gain on the uplink and downlink. In order to operate
properly, an ADJUSTMENT process is required in the field.
Any unused input and output connectors MUST be terminated with 50 ohms –
otherwise the ADJUSMENT procedure results may be affected.

3.1 Infrastructure Preparation
This following installation rules are based on the assumption that site survey and installation
planning (
including power requirements
) have been completed.
3.2 Installation Requirements
The infrastructure preparation consists of two main phases:
A. Floor Planning: Planning the distribution of the antennas on each floor to provide the
required coverage.
B. Telecom Closet Planning: Planning the layout of the devices and cables in the telecom
closet or shaft. This includes the MA 850, 802.11 Access Points, cabling and other voice
service distribution systems that are relevant to the specific installation.
3.3 Coaxial Cable Connections
3.3.1 General Cable Installation Procedures
Observe the general cable installation procedures that meet with the building codes in your
area. The building code requires that all cabling be installed above ceiling level (where
applicable). Each length of cable from the risers to each antenna must be concealed above
ceiling.
The cable must be properly supported and maintained straight using tie-wraps, cable trays and
clamps or hangers every 10 feet (where practical above ceiling level). Where this is not
practical, the following should be observed:
• The minimum bending radius of the supplied ½” coax cable should be 7”.
• Cable that is kinked or has a bending radius smaller than 7” must be replaced.
• Cable runs that span less than two floors should be secured to suitably located
mechanical structures.
• The cables should be supported only from the building structure.
MA 1000 Installation and Configuration Guide
28
3.3.2 Fiber Optic Rules
• Use only single mode fiber for indoor applications.
• Use only 8-degree SC/APC connectors (green color).
• Use only fusion splice for connecting two fibers.
• Use minimum splicing/connectors to achieve minimum losses on the fibers (<0.5dB).
• Use precaution while installing, bending, or connecting fiber optic cables.
• Use an optical power meter and OTDR for checking the fiber optic cables.
• Make sure the environment is clean while connecting/splicing fiber optic cables.
• All fiber optic connections should be cleaned prior to attaching to termination points
using a dry cleaning device (i.e. Cletop or equivalent).
• Fiber connector protective caps should be installed on all non-terminated fibers and
removed just before they are terminated.
• Verify the Fiber Optic connections. You may use the Optical Test Procedure described at
the end of this manual.
• Pay special attention while connecting the SC/APC connectors - you must hear the
“click” when the connection is made.
3.3.3 RF Rules
• Use coax RG223, 50ohm, male-to-male N-type for RF connections from the
BUs to the BTS/RBS and to the RIU.
• When using the MobileAccess™ system in an environment in which other indoor
coverage systems are installed, it is recommended (where possible) that the antennas
are placed at least two meters apart
• When bending coax cables, verify that the bending radius does not exceed the coax
specifications.
• Use wideband antennas supporting a range of 800Mhz to 2500Mhz
• Use a VSWR meter (i.e. Site Master or equivalent) for checking coax cables, including
the antennas. (<2). The VSWR must be measured prior to terminating the RHUs in the
remote communication rooms
• Terminate all unused RHU and RIU ports with a 50 ohm load
MA 1000 Installation and Configuration Guide
29
3.3.4 Coax Cable Lengths and Losses
Use coax ½”, 50ohm, male-to-male N-type, (6-7dB for 1Ghz, 11dB for 2Ghz) for connecting to
RHU and RHU ports.
