DSSS uses only DBPSK for modulation. correct answersFalse (DSSS uses DBPSK at 1 Mbps but uses DQPSK at 2 Mbps) Because of the relatively high speeds achieved with FHSS, it is widely implemented in WLAN systems. correct answersFalse How many adjacent non-overlapping channels may be used in the same physical area using the 2.4 GHz spectrum? correct answers3 Which type of RF signal uses only a single frequency for transmission? correct answersnarrowband

CWNA COMPLETE EXAM GUIDE QUESTIONS 2024. Data Link (MAC and LLC) and Physical (PMD and PLCP) - correct answer What two layers does WLAN technology operate on? 400 ns - increases data rates but not suitable for reflective environments - correct answer Short GI 800 ns - standard, lowers data rates but is more suitable for reflective environments (large warehouses, etc) - correct answer Long GI Frame Aggregation - correct answer Allows for larger frame sizes therefore greater throughput i...
