The gateway has a built-in Global Navigation Satellite System and a Cell-based location engine in combination with a proprietary RF location engine to calculate the position. A built-in quad band gsm modem will send the information to the communication servers. In case the bus gateway in in reach of an RF communication hub, the information can also be sent to the server using the local RF hub which saves on communication cost. ECIS communication monitoring platform guarantees maximum performance at the lowest cost.
