$1\mathrm{.}5$G Spectrum and Bandwidth Allocation

A$.$ Analyze how $5$G allocates spectrum for narrowband communication. B$.$ Compare and

contrast the use of sub$-6$ GHz bands and mm Wave bands in supporting IoT devices.

Include references to specific $3$GPP release documents discussing NB$-$IoT and LTE$-$M

integration within the $5$G framework.

$2.$Waveform and Modulation Techniques

A$.$Provide a detailed analysis of the OFDM waveform and its role in narrowband

communication.

B$.$ Discuss why certain modulation techniques are chosen for specific narrowband

applications.
