MotivationMotivation
• The genesis of this project was the interest of the
Portuguese Navy (PON) in measuring physical
parameters over long distances.
• These parameters were the result of a missile impact
on a naval platform (decommissioned ship).

System’s LayoutSystem’s Layout
The system can be divided into two parts:1. Wireless communication;2. Data gathering.
1.Wireless communication IEEE802.11g standard
(compatible with LAN’s, common routers with wireless,
amplifiers and antennas).
2.Data gathering Dataloggers (associated with
sensors) with LAN interface, high resolution and high
sample rate.

TestsTestsIn order to prove the measurement concept, two tests were made:
•Laboratory tests to all equipment in order to verify their own specific characteristics;
• Some tests were made to validate the system in similar conditions to real situations.

ConclusionsConclusions•This work highlights the potential of Wi-Fi technology in data transmission over long distances;
•Increasing transmission power, higher distances can easily be achieved;
•The available bandwidth at 7.49 Km allows the transmission of data but not of video.

Test the system at high sea;
Construct a high-gain directional antenna for use on the monitoring ship;
Finally, a lot of work must still be done in analyzing the data collected by the sensors, and in optimizing the sensors and sensor layout.
