Broadband Wireless Access at Sea Practice of using at Eastern part of Gulf of Finland
Vysotsk Primorsk Broadband Wireless Access (BWA) network Base Stations deployed on 10 towers. Main reasons : Increasing amount of information; Short of conventional channels; High price of satellite and mobile communication Somers Gogland Seskar Karavalday Kotlin St. Petersburg VTS Center Gorki BASE STATIONS
To increase coverage area antenna suspension are chosen up to 70 m over the ground BASE STATIONS
Typical BS BWA installation
Gogland Somers COVERAGE AREA Modulation & rate 1 MB/s 3 MB/s 4 MB/s Recommended route Proprietary protocol provide high speed (up to 4 MB/s) With narrow bandwidth(1,3 MHz). Coverage area up to 40 km Vysotsk Primorsk Kotlin Ust Luga Seskar Karavaldai VTS Peterhoff Gorki St. Petersburg
