EDGE FCR 3 Operating Instruction

Rev. C, 2019-09-10 Release Page 45 of 64

Peak use cases are defined by a high activity CPU and an intensive edge computing inside the

EDGE FCR 3. Furthermore, to achieve peak values, all communication interfaces must operate

at maximum rates. This combination of usage is only possible with the LTE / 3G HSUPA

operation with bit rates of 42Mbps or higher. Hence, the GSM modem case is irrelevant for

the peak use case and is shown for theoretical completeness only.

The 3GPP Modem may reach a transient peak current 2.5 A (average current 1.1 A), when the

module works at GSM mode (the module transmits at the maximum power) and the power

consume may reach for extreme short times a peak value of 8.25W.

6.4 LTE / 3G / GSM (3GPP) Module Specifications

The LTE / 3G / GSM (3GPP) module, further reference as LTE module, supports two RF

connectors used for external antenna connection. “M” is for Main antenna, used to receive

and transmit RF signals; “D / G” is for Diversity antenna, used to receive the diversity RF

signals.

The LTE module adopts standard M.2 module RF connectors and uses MHF4 connector.
