As far as I can tell, coverage in SF Bay area extends from around Cupertino along 280 to 85, 101,237. Coverage is strong from Cupertino to Menlo Park on the peninsula and across the Dumbarton bridge. LTE signal penetrates the Newark/Fremont zone already, but many dead spots with no LTE and very slow 3G.
I live in Newark, about 5 minutes from the bridge area, and can't get LTE at my house inside or out, but do around the corner.
