  • Page 13: Software Applications

    Software Applications The TB7300 operates in both P25/AS-IP and DMR/MPT networks. Within these networks, the base station utilizes distinct P25/AS-IP and DMR/MPT software applications. 1.2.1 Base Station Features The following is a list of base station features for both P25/AS-IP and DMR/MPT/MPT software applications: Fully compliant with the P25 Common Air Interface.

  • Page 14: Frequency Bands And Sub-Bands

    The 406 to 406.1 MHz frequency range is reserved worldwide for use by distress beacons. It is not legal to program transmitters to operate in this frequency range. b. In Brazil, for K band, the TB7300 is considered to be configured as a base station with retransmission of receive frequencies.

  • Page 15: Software Application Details

    All air interfaces and system types support simulcast operation. In a P25 conventional network, the TB7300 operates as a single or wide area conventional repeater, with receiver voting and optional simulcast.
