3.6.3 WWAN Antenna Connection (3G/4G connector)
The RS123 router family has two connectors for WWAN antennas. To assemble and disassemble the antennas sup-
plied, simply screw them into the connectors labeled 3G/4G (located on the side panels of the router).
Note
This connector is only available on RS123w-4G Devices.
Installing these antennas in the RS123 router is essential in order to improve the quality of the signal received and
transmitted by the cellular model.
Note
To achieve high-quality performance, the router should always have the WWAN antennas installed.
Cellular interface is operative only on RS123w-4G Devices.
Some cellular telephony technologies use the antenna diversity technique to improve the quality of the signal re-
ceived (HSUPA, CDMA EV-DO, etc.). Due to this, the RS123 router family incorporates various WWAN connectors:
Fig. 12: 3G/4G MAIN antenna and 3G/4G AUX antenna
When the MAIN and AUX antennas are not directly connected to the router but installed through extension cords, the
minimum distance between the two of them must be 7 cm. The maximum recommended distance between the two is
25 cm.
To achieve an optimum performance, the radio frequency accessories installed (antennas and cables) should be
those recommended by bintec.
bintec 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.
3.6.3.1 Placing the Antenna
Antenna orientation and its location with respect to other wireless devices and radiation devices (such as communic-
ation devices, personal computers, etc.) can significantly influence device performance.
Antennas transmit and receive radio signals. Performance is also affected by environmental factors such as the dis-
