The Aprisa XE digital access radio is a compact, powerful solution engineered with up to 65 Mbit/s capacity for larger-scale, low and medium-capacity linking applications. Eight interface slots integrated within the radio platform are available for the customer-configurable interface cards. They are easily configured using the embedded 4RF SuperVisor™ network element management application in a Java™ enabled web browser.
Performance
The Aprisa product family has been designed with enhanced features to provide robust, reliable, ‘carrier-class’ transmission performance for long and challenging paths. Reed Solomon forward error correction (FEC) delivers exceptional data integrity while the multi-tap equalizers optimize Aprisa’s multi-path performance. Advanced digital filters provide optimum protection against adjacent channel interference, allowing you to maximize frequency reuse.
With frequency resources becoming limited and expensive we have maximized data throughput with support for 16, 32, 64 QAM and QPSK modulation.
