1 edit | Isn't this just Intel's MyWifi PAN standardized? My daughter's got this in her laptop. (Lenovo with a Intel 5300 wifi card) From what I read on the laptop, it creates a wifi based PAN (personal area network) that Intel called "My WiFi" »www.intel.com/support/wireless/wlan/mywf/ Reduces the amount of cables needed though as pointed out earlier, chargers may be needed instead.
It can but not necessarily allows a shared pass through connection to the web. So assuming you have access at starbucks for 30 min you could use it on the laptop, and allow your iPhone web access since it would already be configured for the laptop connection.
Also, one thing over bluetooth, is "immediate accessibility" that
means that you have access to the material as it is available on the other device. So a camera doesn't actually have to do a transfer, you can see it in the laptop right after it's taken. See: »www.youtube.com/watch?v=5DHBFrPBNc8
It's a PAN so that you don't have to constantly reconfigure ALL of your devices to connect to your laptop (assumed) all the time that is independent of the configuration being used to connect the laptop to the web (wireless or wire). It supports up to WPA2-PSK but all the devices (up to 8) have to have the same security so the lowest level wins if you have older devices but not unlike your router. It's unlikely that your camera, sd card or phone's or printer's wifi can connect to two wifi networks at the same time.
Intel offers both an auto PIN (like bluetooth but not only 4 digits) configuration and a automatic configuration where the device has a configuration button that needs to be set. Legacy devices can be configured in the standard manner. However, you have to allow any device to connect, specifically, there is no totally, automatic configure and accept whatever's in range setting.
Bluetooth is very variable between devices, some have better profiles and capabilities than other devices which only appear when you try to interconnect, e.g, stereo profiles vary greatly between mfgr. WiFi is more 'standard' and backward compatible, IMHO having used mixed devices. Both of these technologies are certainly hackable given computing power and time.
