Note
To get high-quality performance, the router must always have the WWAN antennas installed. The
WWAN interfaces with access to the 2G network (GPRS/EDGE) are operative in all the devices in this
range. To access the 3G network (UMTS/HSDPA/HSUPA) or HSPA+) the device must have additional
licenses installed.
When the RF1 and RF2 antennas are not directly connected to the router but installed through extension cords, the
minimum distance between them must be 7 cm. The maximum recommended distance between the two antennas is
25 cm.
To achieve an optimum performance, the radio frequency accessories installed (antennas and cables) should be
those recommended by us.
We offer a series of accessories (90º mount antennas, antennas for outdoor installation, antennas for ceiling installa-
tion, extension cables, etc.) that allow you to install the devices in different locations.
3.5.2.1 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 significantly 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).
To receive better 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 steer it towards the
nearest base station.
• 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 that could throw shadows and reduce the coverage area.
• Keep the antenna away from metal pipes such as canalization, air-conditioning etc.
• 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 that you install antennas in 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.
• 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.
