Broadband Wireless Communication


High-capacity mesh radio systems for public safety and defense applications

The Challenge

Develop high-capacity mesh radio systems that surpass commercial equipment

CLIENT: Ultra Electronics TCS.


LOCATION: London, UK and Montreal, Canada

Create high-capacity multichannel, multiband, point-to-point (PTP), point-to-multipoint (PMP), and mesh radio systems for public safety and defence applications. These systems must be done at a reasonable price and over a scarce frequency spectrum and meet specific military performance standards and use cases, including security and survivability requirements that are far more rigorous than those for commercial equipment.

Meet military-specific performance requirements

Broadband communication services across multiple networks

Need to be done over a scarce frequency spectrum

The Solution

Partner with Orthogone for technical expertise

To overcome these challenges, a radical approach was required. This was accomplished by leveraging programmable 4G technology into FPGA and Network Processors combined with state-of-the-art broadband RF technologies.

The implementation of an efficient, multiband, and cost-effective radio system.

In-depth customization across multiple layers of the wireless communication stack was then possible to support the various network topologies, security and service delivery requirements of the many use cases needed by military communications. Digital Signal Processing (DSP) algorithms combined with RF technologies were instrumental in realizing a high-performance, multi-band and cost-effective radio system.
