802.11b - 11Mbps per channel over three channels in the 2.4GHz range
|
|
(also shared with microwaves and cordless phones) at rages up to ~300 ft.
|
|
802.11a runs on 12 channels in the 5GHz range and up to around five
|
|
times more bandwidth (~54Mbps or so) but has less range (60-100 ft).
|
|
8021.11a also adds Forward Error Correction into the scheme to allow for
|
|
more reliable data transmission.
|
|
Which to use really depends on what you're doing with it. Streaming
|
|
video almost necessitates 802.11a, while streaming just audio can be
|
|
comfortably done with 802.11b provided that there isn't much
|
|
interference or too many clients.
|
|
Prices? Don't know... Haven't done the research. For covering a large
|
|
area 802.11a will be more expensive due to the need for more APs. If you
|
|
want to reach the local coffee shop, however, you will need a
|
|
directional antenna either way.
|
|
|
|
Check out http://www.80211-planet.com, they've got some good articles on
|
|
802.11... Also, some of the best info on 802.11 security I've seen can
|
|
be found at http://www.drizzle.com/~aboba/IEEE/.
