MBF, Multi Band Repeater

PRODUCT DESCRIPTION AND USER'S MANUAL

1.3.2.2 Highway Coverage

One two-sector BTS feeds two frequency translating repeaters, each covering an area comparable to the base

station. This is a way to get maximum coverage out of the one BTS, with one connection point for

transmission.

Since antenna isolation requirements are low for frequency translating repeaters, omni-directional antennas

can be used at the remote sites to achieve good coverage.

1.3.2.3 “Fake site” – Moving Capacity

In this application the BTS is upgraded with an additional “sector” used for feeding a frequency translating

repeater to cover an area up to 20km away from the BTS. This is an effective alternative when no

transmission point is available in the area to be covered. The frequency translating repeater “moves” capacity

from the base station site to the new location.

Fake Site

This type of installation takes full advantage of the high output power and high sensitivity of the frequency

translating repeater.

1.3.3 Band Shifting Repeaters

A band shifting repeater can be used in the same way as a frequency translating repeater if the user has access

to frequencies on two different bands.

1.3.4 Fiber Fed Repeaters

1.3.4.1 Tunnel Coverage

Fiber optic fed repeaters makes it possible to cover long tunnels from one or two BTS sites nearby. The hub

unit at the BTS site can feed up to 24 repeaters. The repeaters distribute the signal in the tunnel with antennas

or radiating cables (leaky feeders).
