2.4.2 Placement
Requirements. Antenna locations must meet the following requirements for minimum signal
level, physical separation, and isolation.
• Minimum Signal Level: The minimum signal level from any cell to be used as a donor
must be -75 dBm at the D1 antenna connector on the EAC-2100. The minimum signal level
from the donor cell must be at least -100 dBm at the data mobile antenna feed.
• Physical Separation: For diversity operation, the M1 and M2 antennas should be
physically separated by at least 10 feet (3 m) horizontally or 3 feet (1 m) vertically.
F NOTE: Even if diversity reception is not required, both the M1 and M2 antennas
must be installed, since both antennas are used to transmit to the boosted
subscribers.
Multi-hop configurations: An EAC-
2100 not adjacent to the donor
requires a forward signal level of at least -
70 dBm (at the D1 antenna
connector) from the previous EAC-
2100 in the chain. Each booster
along the path must be able to communicate only with the previous
and next booster. They are not required to be able to receive from or
transmit back to the donor cell site.
