Initiatives around the worldsince 2008
all based on expensive and no universal technology
most simulation-oriented
SMARTCOAST, Aveiro, October 2014
5
Motivation
SMARTCOAST, Aveiro, October 2014
Maritime communications unique challenges
Rocking movement
Large vessels as obstacles
Specific radio propagation characteristicsHarsh environment
Affordable long range broadband comms
6
Motivation
Wi-Fi long range maritime communications not yet exploited
Wi-Fi freely available on land
Wi-Fi over license exempt bands
higher Tx power, longer ranges
Wi-Fi is universal and affordable

The Mare-Fi projectWi-Fi for land-sea communications
Objectives
Study Wi-Fi performance for land-sea and sea-sea
comms using license exempt bands
Extend free Wi-Fi on land to the sea using community
networks of fishing ships
Develop Wi-Fi-based comms solutions addressing the
unique challenges in sea environment
SMARTCOAST, Aveiro, October 2014

Roadmap
First phase
– deploy land stations and sea nodes (fishing ships) – MARBED
– study land-sea Wi-Fi comms performance
Second phase
– study ship-ship Wi-Fi comms performance
– extend Porto Digital free Wi-Fi up to 10 nmi
using fishing ships as relays (JANUS technology)
– develop Wi-Fi comms solutions adapted to sea environment

Economical impact– pioneer digital services at sea
e.g., broadband Internet access for fishing ships
– save money spent on celullar/satellite comms
– boost fishermen economical activity
– developed comms solutions and services with
exportation potential

Social impact– increase safety at sea
– users at sea closer to family and co-workers
– contribute to digital inclusion and EU Digital Agenda 2020
– bring broadband to new users and geographical areas
