3800 TETRA Base Station

The ASELSAN TETRA Base Station, designed by ASELSAN, runs on the TETRA communication protocol. The TETRA communication protocol provides frequency efficiency because it has 4 time slots, i.e. 4 different logical channels in a physical channel defined by receive and transmit frequencies. Designed for use by organizations that have a large number of user groups, especially in urban centers, creating intense communication traffic and needing efficient frequency planning, this device can also be used with the switching unit (SoftSwitch) developed by ASELSAN in TETRA wide area communication systems.

ASELSAN TETRA Base Station, which can operate in the 380-430 MHz band, has a modular design that can be configured as 1/2/4/8 carrier. Because it can operate from -30 ° C to +60 ° C, it can be installed in different geographical locations with different climates. The 25 W output (Tx) allows coverage of a large area and TETRA terminals with low power can be serviced by the system using the "3-way receiver diversity" technique used on the receive (Rx) side.

With its IP over Ethernet interface the ASELSAN TETRA Base Station supports both unicast and multicast IP protocols. Thanks to the multicast IP technology used in the system design, installation times of group calls are reduced to the minimum in multi-site systems. By using "GPS disciplined clock" or "Precision Time Protocol (PTP)" in the base station, different base stations can be synchronized with each other, thus providing "seamless handover" for the terminals.

The ASELSAN TETRA Base Station, designed in full compliance with ETSI standards, backs up critical units such as power supply and site control unit. In this version, the base station is located in a compact cabinet that is resistant to environmental conditions such as rain, dust and solar radiation.
