The JUE-251 continues the success of its predecessor, featuring a reliable industry standard interface and an advanced network router in a compact design. The JUE-251 integrates a blockage setting which allows you to register up to 6 blocking areas such as the radar mast or funnel. When the line of sight to the satellite coincides with any of the pre-registered blocking areas, the operator can easily recognize that there is a blockage and can take necessary action such as course change, to restore the connection. Based on 3G standards, FleetBroadband provides constant, simultaneous access to voice and high-speed data, capable of supporting always-on broadband connectivity at speeds up to 284kbps and streaming IP data rate of up to 128kbps. It allows users to send and receive SMS messages of up to 160 characters, a feature that is proven popular with crew who are familiar with texting from their GSM mobiles while on shore.
