What wireless technology does PDA Palm Trio 650 use to allow
internet access almost anywhere?
Digital cell phones (as opposed to the older analog) are already, well,
digital so it was not a giant leap to interface them into the internet via
the phone service provider. As such you have an Internet connection
anywhere you could place a call, I.E. within range of a compatible cell.
It ain't cheap, especially considering it's rather slow.
What wireless technology do notebooks use to gain internet
access at many hot-spots?
802.11a or g.
Someone, bar, store, sports stadium, whoever, has to provide the wireless
access point, with an Internet connection, and it usually costs to access it.
A new 'sport' of 'hunting' for open wireless access points is evolving.
Is Bluetooth the same as 802.11a or b or g?
No. Bluetooth is a different standard for wireless connection of 'devices'
in a short range, 10 meters or so, local network. Bluetooth is about 1 mbps.
802.11a is a different frequency from 802.11b/g, 5GHz, and mainly business
oriented.
802.11b/g are both in the 2.4GHz band and compatible with each other.
