WWAN antennas
Fig. 26:
When the antennas are not directly connected to the router but installed through extension cords, the minimum dis-
tance between the two must be 7 cm. The maximum recommended distance between them is 25 cm.
To achieve optimum performance, the radio frequency accessories installed (antennas and cables) should be those
recommended by Teldat.
Teldat offers a range of suitable accessories (90º mount antennas, antennas for outdoor installation, antennas for
ceiling installation, extension cables, etc.) for different locations.
3.7.3.1 Placing the antenna
The direction of the antenna and its location with respect to other wireless devices and radiation sources (such as
communication devices, personal computers, etc.) can impact device performance.
Antennas transmit and receive radio signals. Environmental factors (such as the distance between the device and
the base station), physical obstacles and other RF interferences can impact their performance.
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 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 those used for plumbing, 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 the face and eyes).
• Do not install the device in areas where the atmosphere is potentially explosive.
