GTR 8000 P25 Base Station/Repeater

GTR 8000 Base Radios support ASTRO® 25 (IV&D) and High Performance Data systems. The GTR 8000 Base Radio is available for IV&D systems in 700/800 MHz, UHF (435-524 MHz) and VHF (136-174 MHz) and for HPD systems in 700/800 MHz. 

G-series site equipment products are very flexible and designed to support today's robust site designs. G-series site equipment products provide the flexibility to upgrade to future functionality through software downloads.



    ASTRO® 25 Trunking
    GTR 8000 Expandable Site Subsystem (ESS), Motorola's premier turnkey RF site design, provides the optimal P25 trunking solution for easy installation and high availability. All base radios, networking equipment, timing and frequency distribution, RF combining and multi-coupler equipment are factory integrated into a single rack or cabinet.
    ASTRO® 25 & Analog Conventional
    Motorola's Conventional channel solutions range from small single repeater sites to wide-area coverage voting and simulcast systems. The GTR 8000 Base Radio’s high performing analog capabilities enable narrow-banding migrations that maximize audio performance.
    ASTRO® 25 Data
    Motorola’s Integrated Voice and Data (IV&D) in ASTRO® 25 trunking and conventional systems as well as High Performance Data (HPD) are supported by the GTR 8000. Voice and data transmissions switch dynamically on the same base radio for ease of use.
    3600 Trunking
    The GTR 8000 base radio supports 3600 trunking operation, enabling new future-ready base radios to be added to existing SmartZone systems with SmartX. The GTR 8000 is software upgradeable to P25 trunking when the time is right to migrate to P25. 3600 trunking operation is available on both simulcast and IntelliRepeater systems, in either analog or digital mode.
