Deployment Example of Onboard DECT System

DECT Deployment based on GA Plan
5.1
Before you install the IP DECT 6000 System on the vessel, it is
necessary to carry out a complete site design based on the GA plan to
determine the exact location of the Server 6000 and base stations, as
well as the number of handsets required.
The vessel that we are using as an example for the IP DECT deployment is a
)
Multipurpose ROV Field Support & Construction Ship.
The deployment of the PoE/base station points covers several decks. In
our example, the Bridge Deck is at the topmost level, the next level down
is the Third Deck, then the Second Deck, the First Deck, the Main Deck
followed by the Below Main Deck areas, namely the Tween Deck and the
Top Tank Deck.
In our deployment example, the Sync Master base station is installed on
the Main Deck, which is approximately midway between the decks above
and below it. All the base stations from the decks above and below the
Main Deck have primary sync ways that lead to the Sync Master on that
deck. The main consideration here is to implement a synchronization
chain that remains intact throughout the multi-cell system onboard ship.
Base Station / PoE Point Notation
5.2
The circle in the illustration at each base station point contains three
numbers: the one in the upper half of the circle is the number of the
base station itself, and the two in the lower half are the numbers of
the base stations on which it syncs with. The first number below the
line is the primary base for synching and the number after the slash is
the secondary base for synching. There are no functional differences
between primary and secondary syncs. To ensure system redundancy, if
the primary sync way is not working, then the secondary sync way takes
over and the synchronization chain is not broken. In this example, base
station 6 has a primary sync with base station 5 and a secondary sync
with base station 4.
‘PoE’ in the circle means that this is a PoE point that is cabled and ready
for extra base stations to be installed if the need arises.
