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.

This research finding from Georgia Tech sounds like it comes from the plot of a high-tech thriller — a team has figured out how to listen in on what someone is typing on a nearby keyboard by using the accelerometer and gyroscope of an iPhone 4 to sense keyboard vibrations and decipher sentences with 80 percent accuracy. Although the actual risk of this happening is essentially non-existent, it’s yet another example of just how important it is that smartphone security be maintained by manufacturers and users alike.favicon follow link
