Radio frequency design

Kordia’s radio frequency design house turns over thousands of RF designs every year across multiple technologies.

These designs range from radio frequency (RF) configuration for mobile base stations to heavy-duty broadcast transmitter ‘plumbing’ designs. Our biggest turnover of RF designs is in PDH and SDH microwave systems in both short and long-haul links.

Microwave network RF designs

Kordia recently completed 600 microwave network radio frequency designs across 222 sites and undertook a mobile carrier’s largest STM-1 link installation schedule. Kordia installed 170 high capacity links over five months, averaging two swaps per night across Australia.

Each STM-1 carries between 50–100 sites worth of traffic, creating potential for extreme risks, and allowing outages for a maximum of only three hours during the low usage period of 10.00 pm to 6.00 am.

Some examples of microwave point-to-point services include:

• thousands of microwave link designs and installations (and maintenance) for Australian mobile carriers since 2003
• microwave long-haul link designs and installations
• microwave radio site pre-rigging inspections, line-of-site evaluations, site audits, installations and commissioning

Special coverage RF designs

Kordia has solid experience in the design, consultation and deployment of multi-technology wireless and mobile coverage radio frequency design solutions that meet the most ambitious coverage goals.

RF engineers, technicians and project managers understand the demand for innovative but cost-effective and flexible solutions in today’s competitive environment.

From planning and system design to coverage, site surveys and project management, Kordia’s specialists provide a complete range of engineering consultancy services. These include construction, integration, commission, optimisation, operations and maintenance.

Kordia offers complete turnkey solutions or works with customers to define specific needs. No job is too large or small and our processes are aligned with best-practice design guidelines to ensure seamless delivery.

In-building radio frequency coverage

Kordia has experience in supporting scenarios that need in-building coverage (passive and active technology) such as:

• small, medium and large corporate office buildings
• shopping centres, airport terminals and public buildings
• university campuses, stadiums, warehouses and factories
• tunnels e.g. shared infrastructure for road and rail tunnels
• microcellular sites e.g. CBD locations, leisure and entertainment areas
• repeater coverage e.g. rural and black spot enhancement
• special events e.g. coverage on wheels (COWs) and temporary coverage.
