                                 Frequencies and Emissions

        The MT will transmit on frequencies in the L-band (1631.5 - 1660.5 MHz) and receive
on frequencies in the L-band (1530.0 – 1559.0 MHz). The frequencies that will be used for
testing and demonstration are within the range allocated to MSV under the L-band operators’
agreement.1

        The maximum possible mobile aeronautical earth station EIRP is 30.8 dBW, but EIRP
will be limited to the minimum necessary to achieve a reliable satellite communications link.

        The maximum possible mobile maritime earth station EIRP is 33 dBW, but EIRP will be
limited to the minimum necessary to achieve a reliable satellite communications link.

Modulation Types employed include:

      1. ABPSK (Aviation BPSK)
      2. QPSK
      3. OQPSK

Communications Bandwidths utilized will include:

1.          2.5 KHz    ACARS Mobile Terminal RSMC Channel
2.          5.0 KHz    ACARS Earth Station PSMC Channel
3.          17.5 KHz   ACARS Earth Station P Channel
4.          17.5 KHz   ACARS Mobile Terminal R Channel
5.          17.5 KHz   ACARS Earth Station T Channel
6.          17.5 KHz   ACARS Mobile Terminal T Channel
7.          200 KHz    Mobile Terminal Broadband Data Link (Aero Demo)
8.          200 KHz    Earth Station Broadband Data Link (Aero Demo)
9.          400 KHz    Mobile Terminal Broadband Data Link (Maritime Demo)
10.         400 KHz    Earth Station Broadband Data Link (Maritime Demo)
