The iPhone 4 on AT&T's wireless network downloads data two times faster than its counterpart on Verizon, a new study has revealed.
Mobile evaluation firm Metrico Wireless conducted thousands of field tests in five prominent US cities where both AT&T and Verizon had a strong presence.
The company said that although AT&T had the faster mean data download speed, AT&T and Verizon iPhone 4s recorded the same web page load time.
Metrico said that when the devices were being used in a moving vehicle, the AT&T iPhone 4 completed around 10 per cent more downloads than Verizon iPhone 4. However, when the devices were stationary, the Verizon iPhone 4 completed 10 per cent more upload sessions than the AT&T iPhone 4.
Some past reports might question Metrico's findings but the company claims that those tests failed to incorporate multiple factors for testing.
Rich McNally, vice president of information products for Metrico, said in a statement “Metrico's results are based on both stationary and mobile [while the user is moving] scenarios at [multiple] locations over five markets and with sample counts in the thousands.”
The Metrico executive informed that the study was not commissioned by any particular carrier and could be purchased by anyone for $4,950.
