When choosing a spread spectrum technology for your wireless LAN network, what are two facts should you consider? Choose 2

A.
An 802.11b Direct Sequence Spread Spectrum (DSSS) signal offers higher data rates and is less susceptible to narrowband interference than an 802.11 Frequency Hopping Spread Spectrum system.

B.
While 802.11g devices can use either DSSS or OFDM technology, 802.11a devices only support OFDM. Therefore 802.11g devices always use OFDM to communicate with 802.11a devices.

C.
When 802.11b devices are present in an 802.11g BSS, the use of DSSS will diminish network throughput significantly over a purely OFDM environment.

D.
An 802.11g system supporting only the data rates required by the 802.11g amendment can interoperate with 802.11b devices.

E.
802.11g systems use OFDM technology to obtain speeds equal to 802.11a systems and to communicate with 802.11b devices.
