The Company wireless network is using 802.11G access points. Which two statements are
true about these access points? (Select two)
A.
It supports eight different data rates.
B.
It is fully backward compatible with 802.11b
C.
It provides the same network throughput with 802.11b clients, 802.11g clients, or a
mixed environment where both clients are present.
D.
It is only compatibly with the 11 Mbps 802.11b transfer rate.
E.
It has three non-overlapping channels in its channel options.
Explanation:
The 802.11g standard is currently the most popular Wi-Fi standard. 802.11g is the successor
to 802.11b, but it is backward-compatible with 802.11b as well. The two standards operate at
the same frequency (2.4GHz). With a throughput of about 22Mbps, 802.11g delivers four
times the throughput of 802.11b. 802.11g has been the de facto home network standard for
a few years and now dominates in retail markets. As it’s been widely adopted, the price of
802.11g products has fallen significantly, making it a cost-effective choice. The only
downside to 802.11g is the fact that it uses a crowded slice of the spectrum, with room for
only three nonoverlapping channels. This will make 802.11a a better choice for some
environments, especially those populated with devices that share the 2.4GHz spectrum,
such as cordless phones, baby monitors, microwave ovens, and Bluetooth radios.
