As we prepared for pushback from DEN; we received a message from Dispatch that numerous aircraft departing DEN were losing their GPS; possibly due to interference from the 5G signals.  We discussed the possibility of losing our GPS on our departure.  During our initial climbout at 800 feet AGL; we received an EICAS message indicating that we lost our ADS-B out capabilities.   I reported this to ATC; and we were told by ATC; that numerous aircraft had been experiencing various navigation/Communication failures which appeared to be due to interference of the new 5G signals.  These failures included loss of GPS; Loss of ADS-B; and loss of transponder. In our case; we only had a loss of the ADS-B out. signal. By FL180 everything returned to normal operations.  We had no further issues with any of our communication and or navigation equipment for the rest of the flight.  We notified Dispatch of our issues while departing DEN.  We did not write up the ADS-B as an ELB; as the problem seemed related to the 5G signal and then went away as we gained more altitude on the climb.
Air carrier Captain reported losing ADS-B out capabilities on departure from Denver.  Reportedly; ATC advised the crew of several ADS-B; GPS and transponder issues possibly due to 5G interference.
