Verizon Wireless has added two new cellular sites to improve wireless coverage on O'ahu and Kaua'i.

A new 'Ewa Beach site improves overall coverage and call capacity for customers in and around the area's residential neighborhoods and industrial sites, as well as the U.S. Naval Reservation at Iroquois Point, Verizon said in news release.

A new Kaua'i site improves overall coverage for customers in and around Puhi, increasing upload and download speeds, as well as providing better in-building coverage for Kaua'i Community College, Puhi Industrial Park and the Home Depot Store, according to the release.

The recent expansion adds to Verizon Wireless' $17 million investment in Hawai'i last year. Nationwide, the company has invested nearly $45 billion since it was formed — $5.5 billion on average every year – to increase the coverage and capacity of its national wireless network and to add services.
