2.1.4 Connecting to the WWAN antenna

The Teldat H Automotive routers can have one or two connectors in order to connect the WWAN antennas. To as-
semble and dismantle the antennas, simply screw them to the connectors labeled WWAN (located at the front of the
device).
Antenna installation is essential in the Teldat H Automotive routers in order to improve the quality of the signal re-
ceived and transmitted by the Wireless WAN module (GPRS, UMTS, HSDPA, HSUPA, etc.).
Note
To obtain optimum performance, the router should always have the WWAN antenna(s) installed,
The device must have the corresponding software license installed to ensure the Wireless WAN inter-
face is operative.
There are some cellular telephony technologies that use the antenna diversity mechanism to improve the quality of
the signal received (HSUPA, CDMA EV-DO, etc...). Consequently, the Teldat H Automotive routers have two
WWAN connectors incorporated.
The following image shows you where to find the antenna connectors in devices that use antenna diversity
(DIVERSITY).
Antenna connectors for Wireless WAN (with diversity)
Fig. 5:
The device incorporates two WWAN antenna connectors ( Main and Ext.Diversity). As a general rule, we recom-
mend that you always install both antennas. You must always install the antenna for the Main connector. The
Ext.Diversity connector antenna is optional. If you are not going to install the Ext Diversity antenna, you need to suit-
ably configure the router (disabling this antenna) to obtain optimum performance from the device.
