Note

Antennas must not be directly connected to the bintec H2 Automotive+ router. They should be at least

50 cm away.

The following image shows the position of the WWAN antenna connectors.

3.6.4 Positioning the antennas

Antenna placement with respect to other wireless devices or other radiation sources (such as communication

devices, personal computers, etc.) can have a significant impact on device performance.

Antennas transmit and receive radio signals. Performance is also affected by environmental factors (such as the dis-

tance between a device and a base station), physical obstacles and other radio frequency (RF) interference sources.

For optimum coverage, follow these recommendations:

• 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 facing the nearest base station.

• Antennas are also affected by material density. Place them away from walls, metal screens, mirrors, etc.

• Do not place the antenna near columns, which may cast a shadow and reduce the coverage area.

• Keep the antenna away from metal objects such as metal duct work, metal pipes, air-conditioning piping, etc.

• Please bear in mind that other wireless devices (such as telephones, microwaves, etc.) can temporarily interfere

with the quality of the wireless signal.

• Installing antennas in racks alongside communication devices, computers, etc., is not recommended. Use an ex-

tension 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.

• Do not touch any equipment containing radiating devices if the antenna is very close to, or touching, any part of the

body (particularly the face and eyes) and is transmitting.

• Do not install the device in areas where the atmosphere is potentially explosive.

• Wireless devices can cause interference in other devices. Do not use them in areas where medical equipment is

installed.

The bintec H2 Automotive+ has a USB HOST 2.0 Type A connector interface, compatible with 3G USB modems.

You activate the interface by purchasing the relevant software license.
