This webinar will provide an introduction into ETSI MEC and specifically the MEC Deployment and ECOsystem DEvelopment Working Group (DECODE). Before getting into the details of the MEC Sandbox, we will highlight MEC resources available to developers, including the MEC OpenAPI specifications on ETSI Forge, the MEC Developer Wiki, and information on MEC Hackathons. We will introduce the MEC Sandbox and do a live demonstration on how to get started. This will include showing developers where to find the MEC Sandbox, how to sign-in, configuring the Sandbox and selecting a scenario. Finally, we demonstrate how to interact with the MEC Service APIs (Location, Radio Network Info, and WLAN Access Info) via a few hands-on examples.
