Compared to LTE, NR has many advantages (Erik Dahlman 2018). Higher frequency bands are exploited to utilize more spectra supporting wider bandwidth for transmission thereby achieving higher data rates. Also, an ultra-lean design is introduced to improve energy eciency as well as reduce the interference. Forward compatibility is ensured to be prepared for unseen future use cases and technologies. By ensuring low latency, the performance of current use cases as well as that of newly introduced ones is improved. Finally, a beam-focussed design is proposed where beamforming is used extensively using an extremely high number of antenna elements for data transmission as well as for control-plane procedures like initial access.
Introduction to computer architecture

Forward compatibility is upward compatibility carried to an extreme. Forward compatibility means that a later family of machines retains the ability (either through direct hardware implementation or emulation of the instruction set architecture) to run programs written and compiled for a previous family. Perhaps the best historical example of forward compatibility is the several families of mainframe computers built by IBM during the 1960s through the 2010s. The zEnterprise family machines being sold as this chapter is being written can still run, without recompilation, programs developed for the IBM System/360 and 370 families in the 1960s and early 1970s.

The data once embedded in the CAD model can either be saved in that CAD package’s native format or it can be saved out to a neutral file format. Compatibility of the embedded data in the CAD package is exactly the same as how that given CAD package handles forward and backward compatibility between files. If CAD package A has an old and new version and the old version will not allow saved files from the new version to be imported into the old version then data that is embedded in the new version native CAD package format will not be imported into the old version. If the old version allows files from the new version to be imported into the old version then the embedded data in the new version can also be imported in. In the case of the first issue where there is only a forward compatibility between native saved files in the CAD package an alternative to getting data that was created in the new version into the old version can use a native file format (NFF) to import in the model and embedded data. The NFF format used by the plug-in is the STEP format. The compatibility of the emended data being imported into a given CAD package is dependent on that CAD package’s import system being built to follow the standards as outlined by the STEP format.
