b. MDT placement
Once the initial Repeater placement is complete, the MDT placement phase begins. Again the
LED feedback can be used to verify that MDTs are communicating with the network. Additional
repeaters can be placed in areas where MDTs are unable to connect to the backbone. MDT to
Repeater (or DCAP) range in open field scenarios is in excess of 1500 feet, however building
construction materials, terrain, and poor location choices can reduce this down to a hundred
feet or less.
The CIT software can also be used in the placement phase to provide more detailed information
such as Link Quality and Signal Strength readings generated by MDT and Repeaters.
c. Mounting Guidelines
Units should never be placed directly on a metal surface
or within a metal enclosure. Mounting
on a metal surface will significantly affect the radio performance of the device, be it an MDT or
a Repeater.
Recommended placement
- Mount on nearby wall away from meter and copper /metal piping
or conduit.
- RF performance is best when mounted on wallboard
- Use keyhole shape to mount on screw in wall
- Designed for #6 Drywall screw
- Separate case to tighten screw if desired
- Note Antenna Pattern shown on the right.
- Radio signal slightly attenuated along the long axis of the MDT
