Section 1 - Product Overview

Introduction

The D-Link 4G LTE Router allows users to access worldwide mobile broadband networks, and share them with a number of

wired and wireless devices. Once connected, users can transfer data, stream media, and send SMS messages. Simply insert

your UMTS/HSUPA SIM card, and share your 3G/4G Internet connection through a secure 802.11n wireless network or using

any of the four 10/100 Ethernet ports.

The DWR-921 keeps your wireless network safe with WPA/WPA2 wireless encryption, preventing unauthorized users from

accessing your network. The DWR-921 utilizes dual-active firewalls (SPI and NAT) to prevent potential attacks across the

Internet, and includes MAC address filtering to control which clients can access your network, and what content they can

access.

The DWR-921 4G LTE Router can be installed quickly and easily almost anywhere. This router is great for situations where an

impromptu wireless network is required, or wherever conventional network access is unavailable. The DWR-921 can even be

installed in buses, trains, or boats, allowing passengers to access the Internet while commuting.
