iPad 3's Wi-Fi Signal Drops Sooner and More Than Other Apple Devices

The hardware involved in the tests were a brand new iPad, a first-generation iPad, an iPhone 4S and an iPhone 3GS for good measure. The access point is a Cisco WRT310N 802.11a/b/g/n single channel wireless access point. Tests were done using the mobile version of SpeedTest, an up/down test utility.
The tests were done over the space of my house, all on the same floor, at various distances with different numbers of walls in between. Tests were done on two servers, one in Los Angeles 32 miles from me, and one in Ft. Worth, Texas, 1,175 miles away.
After numerous tests, TabletPCReview found that the reports were in fact true. The new iPad's signal dropped faster and further than any other Apple device. In the chart below you can see that behind three walls the new iPad's download rate was measured at 0.02 megabits per second compared to 4.14 megabits per second for the iPhone 4S at the same location. The two devices use the same Broadcom BCM4330 chip.
