Deployment Guideline for Below Main Deck
7
The Below Main Deck area comprises the following:
engine room
-
engine control room
-
pump rooms
-
switchboard room
-
storage rooms
-
all other areas below the main deck
-
For these areas, the recommended guidelines for installing base stations
are described below. In our example, Below Main Deck comprises the
Tween Deck and Tank Top Deck.
Engine Room Deployment - Tween Deck
7.1
These areas also include the potential azimuth at the fore section of the
ship. These areas usually have so much equipment already installed that
one (standard) base station on one side each of the (usually) two decks
are sufficient to provide proper coverage, signal strength and stability.
These base stations should be able to take up air sync from the closest
base station on the Main Deck above.

Pump and Storage Rooms Deployment
7.2
These areas include the lower pump room, storage rooms between the
fore and aft engine rooms, rooms enclosing the moon pool, and steel
corridors and narrow spaces.
These areas are either so square (boxy) and narrow that the radio
signals never stop reflecting. The standard base station is no longer
a viable option as much reflection is generated, the handover is bad
between the separate sections/rooms, and the air sync is very unstable.
Consequently, it is better to employ the Leaky Cable Solution (base
