Viewing Wi-Fi Details in Snow Leopard

In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.

On his blog, electromagnetic engineer Bob Egan claims that the RF testing that Consumer Reports did with regard to the iPhone 4 antenna issue was seriously flawed.favicon follow link

He doesn't say it's seriously flawed, he says the number CR came up isn't precise: "I have not seen CR’s claim directly that the finger effect reduces the iPhones sensitivity by 20db as reported elsewhere, but unless CR connected to a functional point inside the iPhone that number is fantasy."

So he doesn't dismiss the report, he says that the number isn't precise. There is no doubt at this point that touching the iPhone antenna at the edge of the phone worsens the signal. The question is by how much.

He says it's flawed in the title of his post, and uses terms like "uncontrolled" and "unscientific." He's not saying, and neither am I, that there isn't a problem, just that this test that purports to show there is a problem is flawed.

For what it's worth, I can't reproduce any sort of problem with my iPhone 4 either.
