The antennas transmit and receive radio signals. This performance is also affected by environment factors (such as
the distance between the device and the base station), physical obstacles and other interferences due to radio fre-
quencies (RF).
For optimum coverage, follow these steps:
• 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 all types of walls, 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 ducts (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 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.
• Do not touch any equipment containing devices that radiate, where the antenna is very close to (or touching) any
exposed part of the body (particularly the face and eyes) while transmitting.
• 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.
• To ensure the R&TTE 1999/5/EC directive is complied with, the device must be at least 15 cm away from a per-
son’s body when operating.
3.6.5 Wireless LAN Antenna Connection (Wi-Fi connectors)
The Teldat V router has two RF antenna connectors for an external antenna to improve the quality of the signal re-
ceived and transmitted by the Wireless LAN module.
This module is 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 , which are
located on both lateral panels of the router.

3.6.6 Connecting a 3G USB device (USB connector)
The Teldat V has a USB HOST 2.0 Type A connector interface that allows 3G USB modems to be connected. The
interface can be activated by purchasing the corresponding software license.
