Warning
!
Any changes or modifications to the equipment not expressly approved by the party
responsible for compliance could void user’s authority to operate the equipment.
Note
!
This unit was tested with shielded cables on the peripheral devices.
Shielded cables must be used with the unit to insure compliance.
Important !
To comply with RF exposure requirement, the antenna must be installed to provide a
separation distance of at least 20 cm from all persons and must not be co-located or
operating in conjunction with any other antenna or transmitter.
CAUTION
This equipment is indoor use and all the communication

RSN-WiMAX-24C repeater is used to fill out areas in Mobile WiMAX systems, such as base
station fringe areas, business and industrial buildings, etc.
RSN-WiMAX-24C receives signals from a base station, amplifies and retransmits the signals to
mobile stations. Also it receives, amplifies and retransmits signals in the opposite direction. Both
directions are served simultaneously with the following features:
188MHz bandwidth service
Band Selection (Continuous 30MHz) service
Roll Offs: 40 dBc at 1 MHz /80 dBc at 3.5 MHz outside pass-band
The RSN-WiMAX-24C Repeaters are controlled by powerful microprocessors. Operational
status LEDs are visible on the front of the repeater.
The repeater works with convection cooling without fan because it has a radiator behind the
body of RSN-WiMAX-24C.

Operational parameters, such as gain, power levels, alarm condition, Automatic Gain Control
condition, etc. are set using a desktop or notebook and the Local GUI or WEB GUI, which
communicate, either locally or remotely via the UTP (Unshielded Twisted Pair Wire) cable, with
the repeater.
