Chapter 2 Introduction

2.1 Description of the device

The Teldat 4Ge device routes outgoing data from a corporate network to the WWAN network (HSPA+/LTE).
• The Teldat 4Ge always operates with the corporate network output router, routing traffic to the WWAN network in
cases where the main corporate output router drops its main connection.
• The technology used in the WWAN access depends on the wireless modem incorporated in the device. The mo-
dem provides access to the HSPA+/LTE networks for data transmission.
• The device has two possible power sources: external, through an element supplied together with the device, or
through POE (Power over Ethernet). In cases where both are present, the external power source takes priority.

2.2 Application Scenarios

The Teldat 4Ge has two application scenarios:
(1) Routers with WWAN communications that have insufficient network coverage due to location problems. It's
common practice to install the communication routers in racks, together with other devices, in rooms where the
WWAN coverage isn't very good.
(2) Backup for routers that don't have WWAN communications and can divert the outgoing traffic to the Teldat
4Ge.
