IP DECT Deployment on Ships

A100K10676

Deployment Guideline for Below Main Deck

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

stations 11 and 12 on the Tween Deck and base stations 14 and 15
