As we enter into a wireless era, we begin looking
for different ways to connect to the Internet. For mobile users, most current
laptops have some kind of built in WLAN capability or a PC Card slot for WLAN
cards. For desktop users, it was never as easy to connect to a WLAN since it was
required to open up a computer. X-micro came up with a way to have access to a
WLAN with almost one step, by inserting the USB Adapter into any USB slot, that
applies to any laptop user or a desktop user. Now we can enjoy the internet
around the house without making holes in the walls for the famous RJ45 cable.
Power: 5V DC
(Max): 11/5.5/2/1/fully auto Mbps
computer, CPU speed of 200 Mhz or above
Memory: 64MB or
above, 128MB recommended
several specifications in the 802.11 family:
-- applies to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4
GHz band using either frequency hopping spread spectrum (FHSS) or direct
sequence spread spectrum (DSSS).
-- an extension to 802.11 that applies to wireless LANs and provides up to 54
Mbps in the 5GHz band. 802.11a uses an orthogonal frequency division
multiplexing encoding scheme rather than FHSS or DSSS.
(also referred to as 802.11 High Rate or Wi-Fi) -- an extension
to 802.11 that applies to wireless LANS and provides 11 Mbps transmission
(with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. 802.11b uses only
DSSS. 802.11b was a 1999 ratification to the original 802.11 standard,
allowing wireless functionality comparable to Ethernet.
-- applies to wireless LANs and provides 20+ Mbps in the 2.4 GHz band.
Here we have a
clear view of the 802.11 technology.
