you are upgrading the wireless network in your cafe from ieee 802.11b to ieee 802.11g to improve internet speeds for your customers. you want to ensure that the new network is backward compatible with older devices that some customers might still use. which feature of ieee 802.11g allows it to support legacy ieee 802.11b devices?\nthe use of the 5 ghz frequency band\nthe ability to switch back to dsss/cck\nthe use of ofdm technology\nthe exclusive use of non - overlapping channels\ni want to review this question later. (optional)
Answer
Answer:
The ability to switch back to DSSS/CCK
Brief Explanations:
IEEE 802.11g can use DSSS/CCK modulation (same as 802.11b) for backward - compatibility. 5 GHz is not used by 802.11b, OFDM is new in 802.11g and non - overlapping channels don't relate to backward compatibility with 802.11b.
