1 Installing the Router
Note
Always install the WWAN antennas to achieve optimum performance from the router.
The device must have the corresponding software license installed in order to activate the Wireless
WAN interface.
Some cellular telephony technologies use antenna diversity techniques to improve the quality of the received signal
(HSUPA, CDMA EV-DO, etc.). For this reason, the Teldat H1+/H1+GE router incorporates two WWAN connectors,
labeled Main and Diversity.

Fig. 14:
If the Main and Diversity antennas are not directly connected to the device but installed through extension cables, the
minimum distance between them must be 7cm and the maximum recommendable distance is 25 cm.
To achieve optimum performance from the installed radio frequency accessories (antennas and cables), these
should be the ones recommended by Teldat.
Teldat has a series of accessories (angled antennas, antennas for external use, ceiling antennas, extension cables,
etc.), which allow you to install the Teldat H1+/H1+GE in different locations.
Placing the antenna
The orientation of the antenna and its location with respect to other wireless devices and radiation devices (such as
communication devices, personal computers, etc.) can significantly influence the device performance.
The antennas transmit and receive radio signals. Performance is also affected by environmental factors such as the
distance between the device and the base station, physical obstacles and other interferences due to radio frequen-
cies (RF).
In order to achieve the best coverage, carry out the following instructions:
• Whenever possible, place the antenna where there are no physical obstacles. Obstacles between the Teldat-3Ge
and the base station degrade the RF signal. Place the device above ground level and ensure that it is suitably ori-
entated towards the nearest base station.
• Density of materials also affects the antennas. Place them away from any type of wall, metal screens, mirrors, etc.
• Do not place the antenna near columns that can produce shadow areas and reduce the coverage zone.
• Keep the antenna away from metal pipes such as canals, air-conditioning.
• Please bear in mind that other wireless devices (such as telephones, microwaves, etc.) can temporarily interfere
with the quality of the radio signal.
• We do not recommend that you install the antenna near or by racks containing communication devices, computers,
etc. Use an extension cable and place the antenna outside.
The following recommendations are applicable to all wireless devices:
• Do not touch or move the antenna while the device is transmitting or receiving.
