Cost-effective, easily managed alternative to high frequency microwave links

Microwave links, typically between 7 and 38 GHz, are commonly used for point-to-point connectivity, particularly in densely populated urban environments, with spectrum and equipment available throughout the world.

For many of our customers, however, higher frequency microwave has its problems, particularly when it comes to expanding connectivity into rural or remote areas.

Problems with high frequency microwave

Advantages of choosing the Aprisa XE

  • Increased congestion in high frequency bands
  • Heavily affected by environmental conditions
  • Many links required to ensure coverage
  • High costs
  • Complex network management
  • Minimal equipment requirements
  • Long range – a single link covering up to 250 km
  • Easy deployment
  • Reduced maintenance requirements and minimised operational expenditure

As well as the increasing congestion of these bands, which can lead to difficulty in deploying links, higher frequency microwave links are affected by environmental conditions, causing signal fading, which means that long distance links are not possible.

This in turn means that multiple links are needed, with ever-increasing capacity as traffic propagates through the network. With more equipment needed to make a long distance link, network management becomes more complex and capital expenditure increases, further complicated by the use of heavy, solid antennas, undermining the business case for connectivity.

Using the Aprisa XE for longer links, particularly into rural and remote areas, has provided our customers with a highly compelling business case and a rapid return on investment. In turn, higher frequency microwave can be reserved for core networks, for high capacity requirements over short distances in urban environments.

Frequently asked questions:

Can sub 3 GHz microwave links provide enough capacity?

While higher frequency systems often have large channel sizes, and hence higher throughput, the Aprisa XE can provide up to 65 Mbit/s of capacity, which is sufficient for many applications.

Is there enough spectrum available in lower frequency bands?

Spectrum availability and congestion levels vary throughout the world, but we’ve found that with support for many frequency bands below 3 GHz, and deployments in over 110 countries, acquiring spectrum licences for the Aprisa XE is rarely a problem.
