1. Introduction Tri MINI repeater is used to fill out areas in iDEN and CDMA mobile systems, such as base station fringe areas, business and industrial building, etc. Tri MINI 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: a.
- DHCP server at the Local port enables Plug and Play by automatically assigning the IP address to the user’s computer. 1. Introduction - TRI MINI utilizes the web-based user interface and web server to support the remote access and control through an external monitoring device with wireless modem. There are two physical RJ-45 ports: • The Local port provides the on-site access to the repeater. • The remote port allows remote users to access the repeater through an external monitoring device.

3. Hardware Installation The installation procedure is as follows: • Check List of Items • Mounting • Grounding • RF Cable Connection • Power On 3.1 Check List of Items Index 1 2 3 4 5 6 7 Items Repeater AC Cord Anchor Bolts Wall Mounting Template UTP Cross LAN Cable Quick Guide User’s Manual Quantity 1 1 4 1 1 1 1 3.1.
Tri MINI is easy to mount using the assembled mounting bracket, which has 9 holes for the provided 5/16” fixing screws. Step 1 Remove the cover of double-coated foam tape squares at each corner on the back side of the template. Step 2 Stick the provided template to the wall using the tape squares while adjusting the horizon. Mark the position for 4 screws depending on the installation location. Step 3 Drill holes directly through the template. User’s Manual 3. Hardware Installation 3.
3. Hardware Installation 16 Step 4 Install the set anchor bolts or the plastic anchor bolts on the holes. Step 5 Attach the mounting bracket to the wall using provided bolts or extra screws.
Lean the Tri MINI to hang the topside of the Guide Ring on the mounting bracket, and push toward the wall to mount. Step 7 Fix the Tri MINI using 8 screws provided. User’s Manual 3.
3. Hardware Installation 3.3 Grounding A rod on the left side is intended for a building ground. Connect the ground cable to the rod. Warning Dangerously high voltages may occur and damage the equipment if the equipment is not grounded properly. 3.4 RF Cable Connection Step 1 Connect a cable from a donor antenna to the DONOR ANTENNA Port. Step 2 Connect a cable from a repeater’s service antenna to the SERVER ANTENNA Port.
Enough isolation? Antenna isolation = Path loss between the server antenna port and the donor antenna port Antenna isolation Repeater max. gain +15dB If antenna isolation < Repeater max. gain +15dB → System oscillation or Low gain Model Max Gain RSN-TRI-25/24-DC 40dB to 80dB(CDMA) ≥95dB(80dB+15dB) 50dB to 80dB(iDEN) Tri MINI Donor antenna for iDEN Base Station Minimum required isolation (@Max Gain) Donor antenna for CDMA 3.
