Fig. 1: : External aspect The Teldat-3Ge is the enterprise access point to the 3G network. This device provides a unique interface with the access router over the corporate Ethernet LAN infrastructure. This singular approach avoids deployment of expens- ive and bulky ultra-low-loss coaxial cables, needed to link the access router to an RF antenna (often located far from interior setups).
Teldat-3Ge Fig. 2: The concept The Teldat-3Ge has two interfaces: the RF interface providing access to the 3G network, and an Ethernet port, which interfaces with the router over the LAN infrastructure. Figure 3 illustrates the basic connection schema: Teldat-3Ge Fig.
Disconnect the power supply from the main electricity electricity supply. supply. If you need redundant power, connect the power supply to the main electricity supply. If you need redundant power, connect the power supply to the device. Connect the Ethernet cable. Teldat-3Ge Installation Manual...
1.2.3.1 With External Power Supply Fig. 4: Connecting the power source The Teldat-3Ge can be powered by an external AC/DC power source through the Ethernet cable if it complies with the POE 802.3af standard. To connect the power supply to the device, please follow the steps set forth in...
Fig. 5: POE Injector: Aspect The Teldat-3Ge can be powered through the Ethernet cable, provided it complies with the POE 802.3af standard. To connect the Ethernet cable with the POE power to the router, please carry out the steps set forth in...

Fig. 7: LAN Connector 1.2.4.2 Connecting the Teldat-3Ge The Teldat-3Ge has one or two connectors for external SMA RF antennas, which improve the quality of the signal received and transmitted through the WWAN module. There are various cellular telephony technologies that use antenna diversity to improve the received signal (HSUPA, CDMA EV-DO, etc.).

For optimum performance, use the radio frequency accessories (antennas and cables) recommended by Teldat. If you use extension cables to connect the antennas to the Teldat-3Ge , they must be H155 coaxial cables. Figure 8 and Figure 9 show you how to install them.
3Ge and the base station degrade the RF signal. Place the device above ground level and steer it towards the nearest base station. • The density of materials also affects the Teldat-3Ge . Place it away from any type of wall, metal screens, mirrors, etc.
GREEN: Communication has been established. The device is ready for normal operations. During startup, the application loads. BLINKING GREEN: There is traffic over the WWAN interface. In Coverage Test mode (blinking more than 3 times per second) this indicates an optimum position. Teldat-3Ge Installation Manual...

OFF: The device cannot startup, please contact the technical service. YELLOW: There is a physical layer in the Ethernet. LEFT LED OFF: There is no physical layer. Check the Ethernet cable. BLINKING GREEN: Data is being received over the LAN. RIGHT LED Teldat-3Ge Installation Manual...
The firmware upgrade is carried out through a conventional TFTP file transfer. You will need a TFTP server where the Teldat-3Ge can download its firmware image. This server can actually be hosted in the current access router. Both the firmware image and the TFTP server IP address are configured in the Teldat-3Ge on startup during DHCP negotiation.
