1. Overview
The LTD-VH1000 is achieved as personal mobile communication devices of the
compact radio equipment, the latest design of the parts becoming smaller, lighter
weight having the 850/1900MHz bands. It is the vehicle’s telematics system that
connect with CDMA(EVDO) wireless network and the wireless module with voice
and data communication. It can be operated at land, rivers, and other similar
areas. On EVDO operating mode, It can be communicated with uplink 1.8Mbps,
downlink up to 3.1Mbps data transfer speed such as a movie or a video call. It
may be able to receive large amounts of data.
Standard RS-232 port and USB port communicating with the host system via ATcommand or control commands can be used to send data. Voice calls are
possible
