Section 1 - Product Overview

Introduction

The D-Link 4G LTE Router allows users to access worldwide mobile broadband networks. 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.

Keep your wireless network safe with WPA/WPA2 wireless encryption. The DWR-921 utilizes dual-active ²rewalls (SPI and

NAT) to prevent potential attacks across the Internet, and includes MAC address ²ltering to control access to your network.

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

impromptu wireless network must be set up, or wherever conventional network access is unavailable. The DWR-921 can

even be installed in buses, trains, or boats, allowing passengers to check e-mail or chat online while commuting.
