The Astra Evolution E6-ST28 is a high-capacity outdoor subscriber terminal designed for professional wireless access and backhaul applications in the five and six gigahertz bands. It integrates a 28 dBi dual-polarized antenna with a narrow 5x5 degree beam pattern, providing excellent signal focus and stable connectivity over distances up to twenty-five kilometers.

Operating across a wide frequency range from 4900 to 6425 megahertz, the E6-ST28 supports channel widths of ten, twenty, forty, and eighty megahertz. It delivers up to six hundred seventy megabits per second of real throughput in an eighty megahertz channel and maintains high performance even under challenging conditions through advanced modulation up to QAM256.

The device incorporates MIMO 2x2 and OFDM technologies to ensure efficient spectral use and link reliability. Adaptive radio control features include automatic bitrate and transmit power adjustment, dynamic distance learning, and configurable uplink and downlink ratios. Built-in spectrum analyzer and antenna alignment tools simplify installation and optimization, while DFS and radar detection provide reliable operation in shared spectrum environments.

Comprehensive networking features include Ethernet-over-IP and IP-over-IP tunneling, multipool NAT, VLAN and QoS support, as well as Astra’s proprietary MINT network protocol for seamless integration into larger systems. The E6-ST28 also offers voice-aware packet handling, ensuring low latency for real-time traffic.

The terminal supports multiple management interfaces such as web GUI, SNMP, and SSH, and is fully compatible with Astra EMS NEXT for centralized monitoring and software updates. A single Gigabit Ethernet interface provides a reliable wired connection, while flexible power options include AC, DC, and PoE inputs.

Housed in a durable weatherproof enclosure rated to IP66 and IP67, the Evolution E6-ST28 operates reliably in demanding outdoor conditions and extreme temperatures. Combining high antenna gain, robust radio design, and flexible management, it is ideally suited for long-distance subscriber links and enterprise-grade wireless access networks.
