Introducing Aprisa XE

A superior design, perfectly executed

The Aprisa XE is a highly stable platform, achieving the greatest possible system gain, capacity and distance, without degradation of signal performance. Receiver performance is optimised to mitigate path interference and distortion, maximising link availability. All this performance is packed into a robust chassis that operates reliably despite temperature and environmental extremes.

The Aprisa XE uses only licensed spectrum bands below 3 GHz. These are relatively unaffected by environmental conditions and allow the use of inexpensive, quickly deployed, lightweight antennas. The Aprisa XE can successfully make even the most challenging links, without compromising on capacity, distance or link availability.

Product Features

High performance RF

Maximum transmitter performance using highly linear Class A LDMOS devices delivers clean undistorted output power. Carefully matched low noise amplifiers produce excellent receiver sensitivity. The designs operate without degrading the performance of the complex modulation. This attention to system signal to noise means a greater system gain, which contributes to the long-distance links the Aprisa XE can achieve.

Sub 3 GHz licensed bands

The Aprisa XE uses only licensed frequency bands, protecting your link and eliminating the commonplace interference issues experienced by links operating in unlicensed bands. It operates in the fixed service bands of the lower microwave spectrum below 3 GHz. This spectrum range offers impressive long haul capabilities, and these bands have been used for this distance advantage since microwave links were invented.

High performance modem

The many possible configurations of the Aprisa XE mean that its capacity varies from 56 kbit/s, in a small channel allocation in a band such as 400 MHz, through to 65.4 Mbit/s where a larger channel allocation is available in a band such as 2 GHz. The Aprisa XE is designed to maximise data throughput using modulation up to 64 QAM. Its high linearity transmitter and low noise reception receiver are engineered for maximum performance, reducing distortion to an absolute minimum and enabling high spectral efficiency at cost points previously thought impossible.

Duplexer architecture

The Aprisa XE duplexer designs use 5 or 6 pole band-pass inter-digital cavity filters to give the best protection from interfering signals. Typical insertion loss is less than 1.5dB and there is over 80dB isolation between transceiver and receiver ports. Duplexer options are available for every transmit receive split used for fixed links below 3 GHz, including duplexers for difficult band plans with very narrow transmitter to receiver spacing. All duplexers use transmission zeros in the filters to provide better close-in attenuation to interfering signals.

Aprisa LTE - Efficient thermal management

Unlimited configuration flexibility

All the functionality and performance of the Aprisa XE is housed in a compact single box architecture.

Key to the Aprisa XE is the built-in multiplexer and cross-connect, providing unlimited configuration flexibility. Digital TDM, IP and analogue legacy interfaces are all supported, with space for eight configurable interface cards.

The modular construction of the Aprisa XE, with transceiver, modem, power supply, duplexer and motherboard all housed in a compact 2U chassis, reduces the mean time to repair and simplifies configuration and management.

The flexibility of the Aprisa XE extends to protected options. Both hitless space diversity and hot standby options are available, for your most mission-critical applications.

Characteristics

Main Benefits

Efficient future-proof single-box architecture

The Aprisa XE’s built-in multiplexer and cross-connect eliminate external equipment and minimize the over-the-air requirements, with customer-configurable interface slots integrating all IP, voice and data traffic. Configuration, performance monitoring and diagnostics are easy with the Aviat’s embedded web-based element management system, SuperVisor.

High capacity

Class-leading spectral efficiency and up to 64 QAM modulation make the maximum use of the available spectrum, with industry leading capacity of up to 88 kbit/s in a 25 kHz channel.

Long range

A single 400 MHz Aprisa XE can link distances in excess of 150 miles, overcoming the problems of water, environmental conditions and topographical obstacles.

Carrier-class performance

Aprisa XE links are engineered to achieve ‘five 9s’ availability, benefiting from state-of-the-art forward error correction and inherent low latencies, for unrivaled quality of service.

Cost effective

The Aprisa XE has a low total cost of ownership, providing a rapid return on investment by minimizing both capital and operational expenditure.

Reliable

The Aprisa XE has an actual MTBF of 95.72 years. It can be relied upon to perform in the harshest and most remote environments.
If your mission is critical, you need the industry-leading performance of Aprisa LTE 5G

Q&A

Why a Solution in the Sub 3 GHz Licensed Bands?

If you have an obstructed path, a need to link over long distances in a single link or are struggling with challenging environmental conditions or harsh terrain, the Aprisa XE can overcome these problems. By taking advantage of licensed frequency bands below 3 GHz, by combining features such as powerful forward error correction and robust equalisation, and through our rigorous manufacturing and quality control programme.
