Product : LTE/CDMA(EVDO) Wireless Modem
Model name : LTD-VL1110
Copyright ⓒ. 2014. All Rights Reserved.
The LTD-VL1110 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.
