Which two of the following statements pertaining to 802.11-compliant systems and co-located access points are accurate? Choose 2

A.
The same number of 802.11b systems and 802.11g systems can be co-located in the 2.4 GHz ISM band without adjacent channel interference.

B.
Up to four 802.11a access points in the5.15 ?5.25 GHz U-NII band can be co-located without performance degradation.

C.
802.11 FHSS systems have a co-location throughput advantage over 802.11b DSSS systems because they are frequency agile and make use of more discrete channels.

D.
802.11g access points configured for 802.11g-compliant operation use protection mechanisms to prevent OFDM transmissions from colliding with the DSSS transmissions. This prevents performance degradation when 802.11g systems are co-located with 802.11b access points.

E.
An 802.11-compliant FHSS system operating at its maximum data rate would require at least three co-located access points to achieve the same throughput as an 802.11b DSSS system operating at its lowest DSSS data rate.
