ETSI Develops Module for Software Reconfigurable Radio
Thursday, October 26, 2017 | Comments

The European Telecommunications Standards Institute (ETSI) Technical Committee for Reconfigurable Radio Systems developed a software model that allows a gradual and stepwise deployment of software reconfigurable radio.

ETSI’s Software Radio Reconfiguration model provides a modular and scalable solution to the challenge of deploying and using software radio systems. The solution is described in a recent ETSI white paper and in the EN 303 146 series of European standards. This enables device manufacturers to gradually implement software reconfigurable radios, developing confidence at each step of the way.

The model provides solutions to the following issues that all software radio systems must address:
• How to securely transfer and install radio software components
• How to provide access to new software components to a user/operator
• How to deal with device certification and type approval when new radio software components can modify the radio behavior of a device
• How to provide software portability and achieve efficient radio performance
• How to gradually evolve a system toward software reconfigurability

Most new cars offer connectivity as a feature, whether standard or optional. Customers expect their navigation systems to be connected to download real-time traffic information and map updates. Vehicle manufacturers increasingly provide remote diagnostics and vehicle software updates. Those these vehicles use 2G, 3G or 4G mobile networks to connect, while long before the end of their useful lives, 5G networks will be more common.

With the use of software reconfigurable radio, the radio system onboard a vehicle can evolve and improve over time, with new software upgrades. Software reconfigurable radios will also help in other situations. For example, security concerns may require the upgrade and patching of radio systems deployed in the field. Yet manual intervention would be costly in the case of vehicles, or even impossible in the case of inaccessible internet of things (IoT) devices.

The ETSI white paper is here.
