4G LTE Wireless AC1200 Router with One Module for Two SIM Cards and GLONASS/GPS Support


The D-Link DWM-321 wireless router has one LTE Cat. 4 interface and provides 3G/4G connection with up to 150 Mbps downlink speed and up to 50 Mbps uplink speed. The DWM-321 is an in-vehicle hotspot device, which allows passengers to get Internet access with wireless devices. In addition, you can use the DWM-321 to organize meetings, seminars, conferences and other events out of the office. The router has two USIM/SIM slots allowing you to use a USIM/SIM card with the most efficient billing plan and backup mobile connection if one of the mobile operators malfunctions (you can switch to redundant conection through the Web UI).
Versatile Usage
With WAN port and 3G/4G support, the DWM-321 allows you to backup wired connection with mobile connection and vice versa, and provide load balancing. Wide range of operating temperatures (-30 to 70 °C) allows you to use the DWM-321 in harsh environmental conditions.
GNSS Antenna*
You can connect the GNSS antenna* to the DWM-321 and track location of the vehicle and analyse its traffic route in details.
Usage of External Wi-Fi Antenna
The ANT24-CB01N conversion cable is required for connecting external Wi-Fi antenna (excluding ANT70-1400N). The ANT24-CB03N / ANT24-CB06N / ANT24-CB09N extension cables are recommended to use for increasing the distance between wireless device and external Wi-Fi antenna.
The ANT-SP lightning surge protection is recommended to use when installing Wi-Fi antenna outdoors. 
* The GNSS antenna is not included in the package contents.
