4.5 Wireless Settings
Wireless Settings includes the basic Wi-Fi settings and wireless security. There are however, some
concepts to be mentioned before going one step forward on the wireless settings. As you know,
802.11 is a set of standards for WLAN communication at the 2.4, 3.6 and 5 GHz frequencies. The
IS150 works only with the 2.4 and 5 GHz range, it follows the below mentioned standards:
802.11a;
(also known as 802.11a-1999), is a 54 Mbps (around 20 Mbps net throughput), 5 GHz
signaling standard; since 2.4 GHz is used by a big number of different devices interference here
is less than in 802.11b. However, signals will not penetrate as much as 802.11b because they
are absorbed more readily by walls and other solid objects (when on a single path), but not
when use in multi-path environments i.e., indoors, office.
802.11b;
the first of the standards to be created; an 11 Mbps (4~5 Mbps net throughput), 2.4
GHz signaling standard. Although it performs much better than traditional dial-up networking, its
performance is still significantly less than 802.11a and other, newer standards.
802.11g;
very similar to 802.11b, the main difference being that it is done in a maximum raw
data rate of 54 Mbps (20 Mbps net throughput), at the same 2.4 GHz bandwidth
802.11n;
more resistant to signal interference from outside sources. Improves the amount of
bandwidth supported by using multiple wireless signals and antennas (MMO technology) instead
of one. Net throughput on a 2x2 solution is about 100 Mbps on our models.
4.5.1 Secure Wireless Wi-Fi Network
When Wi-Fi is enabled, we recommend using WPA2-PSK with AES as a minimum when securing
your network; also remember to set it at 802.11n for a full speed performance. For more information
