Apple Inc is looking for a 4G/5G system engineer on mobility control. Based in California, USA (Bay Area or San Diego). Details Here.
This website tries to:
- explain 5G New Radio based on 3GPP specifications, thus, ensures accuracy of the descriptions.
- provide additional explanations when the specification is not easy-to-understand.
- provide interactive examples alongside the specification. It's much easier to learn things with examples, than trying to figure out how it works by yourself.
- provide a set of toolboxes that can be handly for daily work. E.g., frequency/ARFCN/raster converter, OFDM signal generator etc.
- provide a easy way to browse RRC Information Elements.
