Product : LTE/CDMA(EVDO) Wireless Modem
Model name : LTD-VL1000

Copyright ⓒ. 2014. All Rights Reserved.
The LTD-VL1000 is achieved as personal mobile communication devices of
the compact radio equipment, the latest design of the parts becoming smaller,
lighter weight having the LTE(700/1700MHz), CDMA(850/1900MHz) bands. It is
the vehicle’s telematics system that connect with LTE and 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 LTE operating mode, It can be communicated with uplink 50Mbps, downlink
up to 100Mbps 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
AT-command or control commands can be used to send data. Voice calls are
possible.

4. Electrical specification
4.1 Power supply specification
Modem power(V_BATT) should be provided DC3.8V ±0.1V, 2.0A. Modem
power is provided according to inner function and per block using DC
regulated circuit. It is controlled with each power depending on the
mechanism to reduce power consumption to a minimum. PA is used directly
V_BATT because of a lot of power input power source. Thus, It can be
resulted in breakage of PA in excess of the rated input power. In addition,
surge and ESD should be designed to block the influx in order to prevent
damage to the modem.
