Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 30 September 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 January 2030.

Abstract

The rapid growth of wireless traffic and scaling of massive multiple-input multiple-output (MIMO) radios have pushed existing fronthaul technologies to their limits. Today’s mobile fronthaul based on digital radio-over-fiber (RoF) requires extensive analog/digital conversion at the radio unit (RU) and high-bandwidth digital data transfer. This results in significant energy overhead, costly high-speed electronics,…
