XYZ Company is using a single ERP access point in their New York branch office. There are ten ERP wireless client stations currently on the network, each in use by XYZ’s full-time employees. XYZ has hired a consultant to work on some accounting problems, and he is using an HR-DSSS radio card in his laptop. How might this affect XYZ’s WLAN throughput capacity on whatever channel the HR-DSSS radio is using?
A.
There will be no affect on the channel’s throughput capacity since the access point talks to each station at the highest rate at which the station is capable of transmitting.
B.
The channel’s throughput capacity will remain unchanged, but the HR-DSSS client station will cause the ERP stations to use lower transmission data rates.
C.
The channel’s throughput capacity will be significantly decreased. Additionally, each ERP client station must begin using 20 slot times.
D.
The channel’s throughput capacity will decrease slightly since the only change will be that the HR-DSSS client station will transmit at 11 Mbps instead of 54 Mbps.
E.
The channel’s throughput capacity will greatly decrease due to mandatory use of DSSS-OFDM modulation by all stations.
