PANASONIC AVIONICS CORPORATION ASC-AA8190-01 Enhanced Cell Modem ➢ RF Performance: • Meets ETSI TS 125.101 (3GPP). • There are two characteristics to specify the RF performance; Transmitter power for Transmitter characteristics and Receiver Sensitivity for Receiver characteristics. These are all defined in the ETSI’s specification.
PANASONIC AVIONICS CORPORATION ASC-AA8190-01 Enhanced Cell Modem ➢ Transmitter Power: • Meets ETSI TS 125.101 (3GPP). ➢ Transmitter Attenuation: • The transmitter output level has programmable limitations depending on the mechanism inside the chip. The transmitter output level is limited by the Transmitter power. Maximum output power of Cellular UE is +23 dBm + 1 dBm per 3GPP standard requirement.
PANASONIC AVIONICS CORPORATION ASC-AA8190-01 Enhanced Cell Modem • If any discrete input is not active, the RF frequency bands and RF power amplifier output remains disable and cannot be overridden by software. • The eCM has fail safe circuitry to prevent unacceptable radiated or conducted interference to aircraft system.
PANASONIC AVIONICS CORPORATION ASC-AA8190-01 Enhanced Cell Modem 3.0 ELECTRICAL CHARACTERISTICS 3.1 Power Consumption & Current Draw Power Input: Single Input Power – Cannot operate with AC & DC at the same time. (Note: BOEING Installations – Install with 28 VDC Only, Not 115 VAC).
PANASONIC AVIONICS CORPORATION ASC-AA8190-01 Enhanced Cell Modem 4.0 FUNCTIONS 4.1 Functionality and Interface Characteristics The Enhanced Cell Modem (eCM) is a component of the GCS/eXConnect system designed to provide cellular and wireless data bridge from aircraft to ground network server for gatelink application. The eCM communicates with other head-end equipment through dual ports copper gigabit Ethernet and serves as wireless-to-wired network switch, routing media content, application software and service data.

PANASONIC AVIONICS CORPORATION ASC-AA8190-01 Enhanced Cell Modem 5.4 Discrete Inputs and Outputs Characteristics 5.4.1 5V Discrete Input The eCM provides one maintenance Enable discrete input to allow the unit entering test mode. The discrete input has the following requirements: Logic Low – Enable maintenance mode Ground <...
Under normal operating conditions, when the eCM radios are transmitting in operational frequency bands, there is no potential for interfering with airplane systems. Panasonic chose to use simple hardware to remove power from the COTS radios based on the state of airplane discrete input signals to the eCM in order to preclude the potential for unintended operation resulting in out of band emissions.
• The battery part number is BR1225. • The battery manufacturer is Panasonic with UL file# MH1210; or Rayovac with UL file# MH12542. The battery is not required for safe operation of the airplane; The battery is less than 2 Watt-hours;...
