Chapter 2 Introduction
2.1 Device description
The Teldat 4Ge is a device that routes outbound data from a corporate network to a WWAN network (HSPA+/LTE).
• The Teldat 4Ge is designed to work with the corporate network outbound router, routing traffic to a WWAN if the
primary outbound route for the corporate network fails.
• The device's built-in modem determines the WWAN access technology. The modem is responsible for providing
access to HSPA+/LTE networks for data transmission.
• The device can be powered in two ways: via an external power source supplied along with the device or via Power
over Ethernet (PoE). If both power sources are available, the external power source takes priority over PoE.

2.2 Application scenarios
There are two usage scenarios for the Teldat 4Ge:
(1)
Routers with WWAN communication capabilities that have insufficient signal coverage due to their location. In-
stalling communication routers in racks in rooms that have poor WWAN signal coverage is a common practice.
(2)
Backup for routers that don't have WWAN communication capabilities and that can divert their outbound traffic
to the Teldat 4Ge.
