On departure; [we] received [an] UNABLE RNP EICAS message. [We] believed [the message] to have been directly related to [a] local 5G NOTAM. Due to ATC informing us of [a] previous departure receiving effects of 5G-related malfunctions; [we] strongly believe this to be related to 5G near PDX. 5G near airports is a safety issue affecting automation and navigation.
