1.1 PASO-350 Overview
AMEC PASO-350 is a Simplex AIS Repeater. It complies with all the requirements and regulations imposed
by the international standard. As a repeater, PASO-350 extends AIS coverage and attempts to overcome
terrain obstacles that block AIS radio propagation. Within the AIS service network, PASO-350 is on the
same layer as AIS base stations. There is direct access to the VHF/RF domain equipments for reception
and transmission of AIS VDL messages.
The PASO-350 AIS Repeater doubles the VDL link load for AIS mobile stations and should only be used in
areas with relatively low AIS traffic density.
If the installation site’s AIS traffic loading is very high, some VDL
message dropping could occur due to AIS repeater standards. It is recommended that the installation sites
for PASO-350 have less than 25% of the VDL link load.
