Note
The WWAN antennas should be connected to the router at all times in order to deliver high-quality per-
formance. All devices in this range have working WWAN interfaces with access to 2G networks
(GPRS/EDGE). Additional licenses must be installed in the device for access to 3G networks
(UMTS/HSDPA/HSUPA) or HSPA+).
If the RF1 and RF2 antennas are connected via extension cables rather than being screwed directly into the router,
they should be separated from each other by a minimum of 7 cm. The maximum recommended distance between
the two antennas is 25 cm.
To achieve optimum performance, install all radio frequency accessories (antennas and cables) as per our recom-
mendations.
We offer a range of accessories (90 degree antenna mounts, exterior antenna mounts, ceiling mounts, extension
cables, etc.) that allow you to install the devices in different locations.
3.5.2.1 Positioning the antenna
Device performance can be significantly influenced by antenna orientation and location with respect to other wire-
lessdevices and radiation sources (such as communication devices, personal computers, etc.).
Antennas transmit and receive radio signals. Performance is also affected by environmental factors (such as the dis-
tance between the device and the base station), physical obstacles and radio-frequency (RF) interference.
In order to receive better coverage, follow the instructions given below:
• Whenever possible, place the antenna away from physical obstacles. Obstacles between the antenna and the
base station degrade the wireless signal. Place the antenna above ground level and direct it towards the nearest
base station.
• Antennas are affected by the density of materials so place them away from walls, metal screens, mirrors, etc.
• Do not place the antenna near columns; these might throw shadows and reduce the coverage area.
• Keep the antenna away from metal pipes such as those used for plumbing, air-conditioning etc.
• Bear in mind that other wireless devices such as telephones, microwaves, etc., can temporarily interfere with
thequality of the wireless signal.
• Installing the antennas in racks alongside communication devices, computers, etc., is not recommended. 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 equipment containing devices that radiate very close to, or touch-
ing, 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.
• In order to comply with the R&TTE 1999/5/EC directive, the device must be at least 15 cm away from a per-
son’sbody when operating.
3.5.3 Connecting the serial ports
Depending on the model, the Regesta PRO PLC can have one or several female DB9 connectors.
