AT&T Upgrades Network Capacity on Coastside, San Mateo County

Forty-five cell sites with increased capacity equivalent to adding another lane of traffic on Bay Bridge at rush hour.

On Friday, AT&T announced upgrades in 45 cell sites across San Mateo County designed to increase coverage and expand capacity.

The upgrades should make an immediate impact on both network accessibility as well as staying connected to the network, the company said.

“Adding more capacity to a cell site is like adding more lanes on the freeway so that voice and data traffic flows faster,” said Terry Stenzel, AT&T Vice President and General Manager for Northern California and Northern Nevada.

George Ross, a communications liaison with SCN Strategies, said that data traffic on the AT&T network has increased by 8,000 percent in the last four years.

"All that data usage requires additional spectrum to continue moving at the speeds customers expect," he said.

Upgraded networks are now in place for the following cities:



Daly City

Half Moon Bay (3 carrier additions)

Menlo Park


Montara (2 carrier additions)

Moss Beach (1 carrier addition)

Pacifica (4 carrier additions)

Portola Valley

Redwood City

San Bruno

San Mateo

South San Francisco

AT&T said that it also continues to upgrade cell sites with fiber optic and Ethernet connections back to the central switching facilities, which enables faster 4G speeds.

"Whether customers are talking, texting, e-mailing, surfing the net, streaming music or video, using their favorite apps, or conducting business we want to make sure they have a good mobile broadband experience,” said Stenzel.

The company said that it could not give details on the exact amount coverage and capacity would increase from the upgrades until it could collect data from the sites itself.

I have sprint and live in park pacifica. I think i would have better odds at winning the lottery than getting a clear data signal. Nevermind that sprint has been charging extra for 4G that we NEVER GOT BACK HERE AND STILL DONT! I cant get a clear data 3G signal for more than a couple min without a roaming alert. Somebody tell me why i have an unlimited data plan when i cant get a data signal! Soup cans and a long string are lookin pretty good right now!!
