RF Rules
•
Use coax ½”, 50ohm, male-to-male N-type, (6-7dB for 1Ghz, 11dB for 2Ghz) for
connecting to RHU and RHU ports.
•
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 Corning 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

SAFETY WARNINGS
•
When installing or selecting the power supplies:
•
Be sure to disconnect all power sources before servicing.
•
Calculate the required power according to the requirements of the specific installation
and then determine the configuration of the power supplies. The required DC cables will
then be determined by the selected PS configuration.
•
Use only UL approved power supplies
•
AC and DC power supply cables – use only the power cords supplied with the units
•
Install external over-current protective devices for the system according to the
requirements described in section
3.4.3.
