Zhone Building[edit]

The Zhone Building at 7001 Oakport Street is a prominent detached building, next to Interstate 880 in East Oakland. The 66th Street exit was renamed "Zhone Way" west of 880, leading to Oakport. The building was the headquarters of Zhone, until they moved to a smaller building behind it, at 7195 Oakport Street.


Zhone's SkyZHone Metro Wi-Fi System is approved by the Rural Utilities Service for use in rural areas.
