Hughes is synonymous with innovations in satellite communication industry. From Claircomm to ICO, from Thuraya to Spaceway, Hughes has a wide range of experience in all technologies of this mature industry.

HSC engineers have enriched experience in standardization (GMR-1), implementation: Ground segment (Transceivers, Resource management, Resource Payload control, OMC, NOC) and user segment (Terminals for voice/data). With the experience of having participated in the design and development of major satellite systems, HSC engineering has the following offerings:

Product reengineering helps vendors of network equipment in established technologies offer substantially improved components for their customers. Product reengineering may involve one or more of the following:

• Software reengineering: This is done to improve the capacity, reliability, performance or feature set supported by a given software component. Depending on the context, it might include porting to a different platform, or re-engineering in order to meet tighter resource and performance requirements. An example is the re-engineering of legacy GPRS base stations to reduce cost per channel and improve data throughput and QoS management.
  
  
• Product enhancements: This means improving internal algorithms and features to give additional capacity to an existing software product. The key challenge is to do this without breaking any existing software functions, many of which (for long-lived products) are incrementally developed on the base specifications. Thus, the enhancement requires a long and exhaustive test-cycle, even if the software development is only incremental.

Network design and modeling is required by network operators as they launch new networks, re-engineer existing networks and/or interwork between networks. Examples are

• Capacity analysis of a proposed system of a given radio plan and spectrum.
  
  
• Air Interface Protocol specification and Validation.
  
  

The HSC team brings to this task a comprehensive set of skills, ranging from formal network modeling, design consultancy to an integrated test planning.

HSC works with network component vendors to develop custom software units, ranging from protocol stacks, to functional components such as schedulers, compression engines, call management engines and resource management engines.

Built to specification from the customer, these software components incorporate technologies contributed both by HSC as well as the customer's engineering and are written in a modular, testable manner, enabling easy integration into customer products. Along with the component, HSC works with the customer to help integrate and test this software into the final product.
