Updated: Report: Dunkin' Donuts has fastest Wi-Fi download speeds among coffee chains

In honor of National Coffee Day (yes, there is such a thing), wefi released analytics regarding Wi-Fi connectivity trends at coffee chains such as Starbucks, Dunkin' Donuts, Tully's Coffee and Panera Bread.

Dunkin' Donuts had the fastest download speed at 6.09 Mbps, while Starbucks came in second with 4.11 Mbps, wefi said in a reissued press release. An earlier release from the company included incorrect results due to an issue with data retrieval, a wefi spokesperson said.

Starbucks showed the fastest average effective throughput at 0.18 Mbps. Starbucks, Dunkin' Donuts, Tully's also had the highest total data consumption among the coffee chains, led by Tully's, whose patrons consumed on average 27.75 MB, according to the updated release.

Wefi did not compare the performance of Wi-Fi service delivered by Google (NASDAQ: GOOG) vs. AT&T Mobility (NYSE: T) within Starbucks locations. In August, Open Signal released a study that revealed Wi-Fi supplied by Google at Starbucks outperformed locations whose Wi-Fi service was powered by AT&T. Likewise, SpeedSpot in July confirmed that its users experienced up to 18 times faster download speeds at Starbucks locations that had swapped out their AT&T Wi-Fi service for Google's.

According to wefi, Google Chrome, Facebook (NASDAQ: FB) and YouTube are the applications most used over Wi-Fi by coffee shop patrons.

"With many franchisees looking to provide additional services and grow their businesses, the availability of a fast, reliable Wi-Fi offering has become an important consideration," said Zur Feldman, chairman and CEO of wefi.

Similarly, Time Warner Cable (NYSE: TWC) released a survey of small businesses earlier this year that revealed 80 percent of respondents believe their customers expect free Wi-Fi.

For its report, wefi collected data from more than 45 million hotspots based on the implementation of its intelligent network selection solution within multiple cable operators throughout the United States. The metrics are based on a 30-day average of Wi-Fi speeds for each location during the month of August 2014.
