D-Link's DWR-921 4G LTE Router allows you to access and share your 4G LTE or 3G mobile broadband connections. Once connected, you can transfer data, stream media, and send SMS messages. Simply insert your SIM/USIM card and share your 4G LTE or 3G Internet connection through a secure wireless network or any of the four Ethernet ports. The DWR-921 4G LTE Router is designed with constant connection in mind. Dual-band 4G LTE and 3G support allows automatic 3G connection if or when the 4G LTE signal strength becomes low, whereas the additional xDSL/FTTH Ethernet WAN option gives fail-safe connectivity if either your fixed line or mobile broadband fails. The 4G LTE Router lets you connect to your 4G LTE mobile connection with fast download speeds of up to 100 Mbps and upload speeds of up to 50 Mbps, giving you a fast and responsive Internet experience, allowing you to surf the web with ease and stream music and video without buffering. The DWR-921 utilises dual-active firewalls (SPI and NAT) to prevent potential unwanted intrusions from Internet. WPA/WPA2 wireless encryption keeps your wireless network secure and your traffic safe, allowing you to securely share your 4G LTE or 3G connections without worrying about unauthorised users accessing your network.
