Wireless Lan Antenna Connection (Wi-Fi Connectors) - Teldat iM8 Installation Manual

3 Components and Power Supply
WWAN Main and Aux 1 antennas
Fig. 24:
When the Main and Aux 1 antennas are not directly connected to the router but installed through extension cords,
the minimum distance between the two of them must be 7 cm. The maximum recommended distance is 25 cm.
To achieve optimum performance, the radio frequency accessories installed (antennas and cables) should be those
recommended by Teldat.
Teldat has a series of accessories (90º mount antennas, antennas for outdoor installation, antennas for ceiling in-
stallation, extension cables, etc) for installation in different locations.
3.7.3.1 Placing the Antenna
The orientation of the antenna and its location with respect to other wireless devices and radiation sources (such as
communication devices, personal computers, etc.) can influence the performance of the device.
Antennas transmit and receive radio signals. This 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).
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.
• Density of materials also affects 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 canals, air-conditioning, etc.
• 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 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 device 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 device in areas where the atmosphere is potentially explosive.
• Wireless devices can cause interferences in other devices. Do not use the device in areas where medical equip-
ment is installed.

3.7.4 Wireless LAN Antenna Connection (Wi-Fi connectors)

The Teldat iM8 has four RF antenna connectors for an external antenna to improve the quality of the signal received
and transmitted by the Wireless LAN module.
These modules are internal and can be activated by purchasing the corresponding software license. To assemble
and disassemble the antennas provided with the device, just screw them into the connectors labeled Wi-Fi. They are
located on the rear and on both lateral panels of the router.
