Benefits of SDR:

The benefits of SDR are compelling.

For Radio Equipment Manufacturers and System Integrators, SDR Enables:

A family of radio “products” to be implemented using a common platform architecture, allowing new products to be more quickly introduced into the market.

• Software to be reused across radio "products", reducing development costs dramatically.
• Over-the-air or other remote reprogramming, allowing "bug fixes" to occur while a radio is in service, thus reducing the time and costs associated with operation and maintenance.

For Radio Service Providers, SDR Enables:

• New features and capabilities to be added to existing infrastructure without requiring major new capital expenditures, allowing service providers to quasi-future proof their networks.
• The use of a common radio platform for multiple markets, significantly reducing logistical support and operating expenditures.
• Remote software downloads, through which capacity can be increased, capability upgrades can be activated and new revenue generating features can be inserted.

For End Users - from business travelers to soldiers on the battlefield, SDR technology aims to:
 
• Reduce costs in providing end-users with access to ubiquitous wireless communications – enabling them to communicate with whomever they need, whenever they need to and in whatever manner is appropriate.

Adoptation:

Examples of SDR adoption illustrating the transition to the mainstream are abundant:
• Thousands of software defined radios have been successfully deployed in defense applications
• Cellular infrastructure systems are increasingly using programmable processing devices to create “common platform” or “multiband multiprotocol” base stations supporting multiple cellular infrastructure standards
• Cellular handsets are increasingly utilizing System on Chip (SoC) devices that incorporate programmable “DSP Cores” to support the baseband signal/modem processing
• Satellite “modems” in the commercial and defense markets make pervasive use of programmable processing devices for intermediate frequency and baseband signal processing
