Antenna connectors for WWAN (with diversity)
Fig. 16:
Depending on the connecting technology, you will need to use one (e.g. GPRS) or two antennas (e.g. LTE).
You must always install the antenna for the R1, C1 (Main) connectors (mandatory). The R2, C2 (Ext.Diversity) an-
tenna connectors are optional.
In some models, if you are not going to install the Diversity antenna you need to configure the router accordingly
(disabling this antenna for optimum performance).
When you install both the Main and the Ext.Diversity antennas, the minimum distance between the two must be 7
cm. Maximum recommended distance is 25 cm.
For optimum performance, use the radio frequency accessories (antennas and cables) recommended by Teldat.
Teldat has a range of accessories that allow Teldat H2 Automotive routers to be installed in different locations.
Note
Antennas must not be directly connected to the Teldat H2 Automotive router, but at least 50 cm away.
3.6.6.1 Positioning the antenna
Antenna orientation and its location with respect to other wireless devices and radiation devices (such as communic-
ation devices, personal computers, etc.) can significantly influence device performance.
Antennas transmit and receive radio signals. Performance is also affected by environmental factors (such as dis-
tance between the device and the base station), physical obstacles and other interferences caused by radiofrequen-
cies (RF).
For optimum coverage, carry out the following instructions:
• Whenever possible, place the antenna where there are no physical obstacles. Obstacles between the antenna and
the base station degrade the wireless signal. Place the antenna above ground level facing the nearest base sta-
tion.
• The 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, which may throw shadows and reduce the coverage area.
• Keep the antenna away from metal pipes such as canalization, air-conditioning, etc.
• Please bear in mind that other wireless devices (such as telephones, microwaves, etc.), can temporarily interfere
with the quality of the wireless signal.
• We do not recommend installing antennas near, or between, racks containing communication devices, computers,
etc. Use an extension cable and place the device outside.
The following recommendations are applicable to all wireless devices:
• Do not touch or move the antenna while the router is transmitting or receiving.
• When the antenna is transmitting, do not touch any equipment that contains devices that radiate very close to, or
touching, any exposed part of the body (particularly face and eyes).
• Do not install the router in areas where the atmosphere is potentially explosive.
• Wireless devices can cause interferences with other devices. Do not use the router in areas where medical equip-
ment is installed.
