Chapter 1 Introduction

1.1 Device definition

The Teldat-3Ge-USB (also known as the Antenna Ethernet-3G-USB) device routes outgoing data from a corporate
network to the WWAN (HSDPA/HSUPA).
• The technology used for WWAN access depends on the USB modem you connect to the device. The modem
provides access to the HSDPA, HSUPA, UMTS and GPRS networks.
• The device can be powered by an external source (supplied with the device), or via Power over Ethernet (PoE).
The external power source takes precedence when both types of power supply are available.

1.2 Application Scenarios

There are two application scenarios for the Teldat-3Ge-USB:
(1) Routers with WWAN communications where the WWAN coverage is poor due to problems with the location of
routers. Communications routers are often installed in racks alongside other equipment in rooms where WWAN
coverage is not very good.
(2) Backup for routers that do not have WWAN communications and can divert outbound traffic to the Teldat-
3Ge-USB.
