(3G / 4G)
Antenna Placement
When in service the antenna should be placed away from electronic devices or
other antennas. The recommended minimum distance between adjacent antennas,
operating on a similar radio band, is at least 50cm.
Antenna Connection Cable
If a cable is used to connect the antenna to the router this cable must be a high
quality low loss cable. The cable and any connectors used should have 50 ohms
impedance.

Installation
Considerations for Installations Incorporating the MICA-Compact
There are several conditions which need to be taken into consideration when
designing your application as they might affect the router and its functionality. These
are:
Environmental conditions: The router must be installed so that the environmental
conditions stated such as temperature, humidity and vibration are satised.
Additionally, the electrical specications must not be exceeded.
Signal strength: The router/antenna has to be placed in a position that ensures
sufcient signal strength. To improve signal strength, the antenna can be moved to
a more elevated position. Signal strength usually depends on how close the router is
to the base station. You must ensure that the location at which you intend to use the
router is within the network coverage area. Degradation in signal strength can be the
result of a disturbance from another source, for example an electronic device in the
immediate vicinity.
When considering the location for the router and antenna placement, you must
consider received signal strength as well as cable length as long cable runs can
attenuate the received signal strength.
Connections of components to MICA-Compact Series routers: The system
integrator is responsible for the nal system solution. If external components are
incorrectly designed or installed it may cause radiation limits to be exceeded. For
instance, improper cable connections or incorrectly installed antennas can disturb the
network and lead to router malfunction.
Network and subscription: Before your application is used, you must ensure that
your chosen network provides the necessary telecommunication services. Contact
your service provider to obtain the necessary information.
» If you intend to use SMS in the application, ensure this is included in your
subscription.

Power Supply Installations
»Use a high-quality power supply with short leads. This ensures that the voltages
at the connector pins are within the specied range, especially during the
maximum peak current of approximately 2A.
» When the router is powered from a battery or a high current supply, connect a
fast 1.25A fuse in line with the positive supply. This protects the power cabling
and router from damage.
Securing the Router
Before securing the router please take into account the amount of additional space
required for the mating connectors and cables that will be used with the router in the
application.
» Where access is restricted, it may be easier to connect all the cables to the router
prior to placing it in the application.
