The requirements for a WLAN you are installing state that it must support unidirectional delays of less than 150 ms and the signal strength at all receivers can be no lower than -67 dBm. What application is likely used that demands these requirements?
The requirements mentioned in the question, such as unidirectional delays of less than 150 ms and signal strength no lower than -67 dBm, are typical for applications that require real-time communication. This aligns with Voice over IP (VoIP) applications, which are sensitive to delays and require strong signal strength to maintain call quality. E-Mail and FTP are not latency-sensitive applications, so they do not fit the given requirements. RTLS could benefit from low latency but does not usually have strict requirements like < 150 ms. Therefore, the correct answer is VoIP.
RTLS is Real Time Location Services, though it works best with lower latency, it does not require < 150ms latency. VoIP is the right answer, answer C
Should be C .
I think C is correct
Answer is C - VoIP
