Outdoor is the share of the area where the carrier reports 4G LTE or 5G to a phone standing still outdoors; in car is the share it reports to a phone in a moving vehicle, which is always lower. Indoor signal is not part of the FCC filing and can be weaker than either.
4G and 5G across all carriers in Portland
Share of Portland's area where at least one carrier reports each technology outdoors. "5G 7/1" means 5G of at least 7 Mbps down and 1 Mbps up, "5G 35/3" at least 35/3 Mbps, the two speed tiers the FCC publishes. The FCC summary does not split 5G by carrier.
Choosing a carrier in Portland
All three carriers report about the same coverage in Portland, so price, data allowance and contract terms can decide it. Check the street you live on in each carrier's own map before you commit, because a city-wide share can hide a dead spot.
