CWNA Exam Questions & Answers 2023/2024 DSSS uses only DBPSK for modulation. - ANSWER-False (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. - ANSWER-False How many adjacent non-overlapping channels may be used in the same physical area using the 2.4 GHz spectrum? - ANSWER-3 Which type of RF signal uses only a single frequency for transmission? - ANSWER-narrowband How wide ...

dcom 251 8-14 final exam Question and answers 100% correct 2024 Which of the following is not a WLAN security standard? - correct answer WAP WLAN security based on a PSK technology is called ________ mode. - correct answer personal The strength of the electromagnetic waves being radiated from an antenna is referred to as gain, which involves a measurement of both direction and efficiency of a transmission. Gain is commonly measured using the dBi unit of measure. - correct answer true ...

What is the fundamental requirement of OFDM? It has orthogonality. The frequency spacing is 1/T which leads the signal to be orthogonal. If the bit time of the carrier is T, then the base frequency must be chosen to be a multiple of 1/T. OFDM Multiple carrier signals at different frequencies that send some bits on each channel. OFDMA Like OFDM, except that it is a multi-user version. Multiple access is achieved by assigning subsets of subcarriers to individual users. SC-F...
