The Verizon Wireless Network has added new 4G LTE cell sites along Vineyard Avenue, Isabel Avenue and Stanley Boulevard.
Verizon also has added new cell sites in Berkeley, Fremont and Oakland as part of its $7.8 billion in continuing investment to improve its California network since the company was founded in 2000.
Nationally, a Verizon representative said the company has invested more than $80 billion over that same period to increase the coverage and capacity of its network, and to add new services.
"The network upgrade is part of the company's ongoing investment to keep improving and strengthening the nation's largest and most reliable wireless network," the Verizon spokesman said.
Other sites in Alameda County that now have improved wireless coverage are:
