Teldat has a series of accessories (90º mount antennas, antennas for exterior installation, antennas for ceiling install-
ation, extension cables, etc.) that allow you to install the devices in different locations.
3.5.2.1 Placing the Antenna
The orientation of the Teldat 4Ge device and its location with respect to other wireless and radiation devices (such
as communication devices, personal computers, etc.) can significantly influence performance.
The Teldat 4Ge device transmits and receives. 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, 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 and facing the nearest base
station.
• The density of materials also affects antennas. Place them away from 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.
• 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 with other devices. Do not use the device in environments where medic-
al equipment is installed.
• To ensure compliance with the R&TTE 1999/5/EC standard, the device must be at least 1.5 cm away from a hu-
man body when operating.
3.6 Installing the SIM card
A SIM card needs to be inserted in the Teldat 4Ge so the WWAN interface operates correctly. The router is
equipped with an external SIM card tray.
When inserting the SIM card, make sure you are protected against electrostatic discharges (ESD).
Warning
Do not touch the SIM card connector.
