Special LED functions:
During a software download from CloudGate Universe
When the CloudGate is downloading new firmware from the CloudGate Universe the
LED behaviour is different compared to normal behaviour. In this situation the LEDs are
11

moving fast from left to right and back. The colors of the LEDs indicate the next:
Orange: A new firmware is being downloaded
Green: The download was successful. (This will be followed by a reset of the
CloudGate)
Red: The download was not successful.
During the bootup process
When the CloudGate is booting up, the System State LED behaviour is different
compared to normal behaviour. In this situation the System State LED flashes red and
orange. This process is expected behavior and can take up to a minute.
Please not that this only applies on CloudGate devices with a '2' as the third digit in the
serial number, f.e. MJ2xxxxxxx. CloudGate devices with a '1' will show their System State
LED solid orange during the early boot process.

7 Not used
8 Not used
IMPORTANT: The auto-MDIX feature is always activated on the CloudGate. This feature
automatically detects the required cable connection type (straight or crossed), and
configures the connection appropriately, removing the need for crossover cables.
In order for auto-MDIX to work correctly, auto-negotiation (auto speed and auto
duplex) must be enabled on both sides of the link. Note that auto negotiation is always
active on the CloudGate.
WAN/LAN Switchover Feature
The WAN/LAN switchover feature is a mechanism to maximize the internet connectivity
via the Ethernet port.
The description of the related configuration parameters and the switchover mechanism
itself can be found in the Ethernet Tab section of the CloudGate Setup Guide.

RF and antenna specifications of the CloudGate LTE WW
Warning for antenna assembly
The antenna has to be assembled in such a way that only the nut is rotating onto the
SMA connector. The antenna body itself may not be rotated. In this way the inner
conductor of the antenna is sliding into the SMA connector without rotation. This is the
best way to provide a reliable RF contact.

Diversity WWAN Antenna
The diversity antenna is labelled WWAN Div GPS on the front panel. Learn about
antenna recommendations for the CloudGate LTE WW.
IMPORTANT: The diversity antenna is by default disabled (from firmware version 1.9.0
onwards). Learn how to enable the diversity antenna.
Connectors
Uses the same type of connector as the main WWAN antenna
Frequency range
Receive diversity only works on WCDMA and CDMA bands
Only WCDMA and CDMA bands have to be supported by the diversity antenna.
The GPS frequency must also be supported if GPS functionality is desired on the
CloudGate.

GPS Antenna
There are two hardware variants of CloudGate LTE WW: one with passive GPS and one
with active GPS.
This section explains the variant with passive GPS antenna, it has no power
supply for active antennas on the RF connector. For accurate GPS operation
make sure the GPS antenna has a clear view of the sky.
The variant with active GPS is explained in the section about Active GPS
Maximum VSWR

Efficiency: > 50%.
Important: a CloudGate LTE WW with active GPS does not support the MIMO LTE
antenna. Instead it must be equipped with an active GPS antenna. See the relevant
section about Active GPS for more information.
RF EXPOSURE WARNING
To comply with regulatory requirements, please check the maximum allowed antenna
gain for your your external antenna! The maximum gain is specified for each product in
the certification information section of the CloudGate LTE WW.
