Question 3

Allowable levels for transmit power

When connecting two wired LANs via a wireless point-to-point connection, it is crucial for the technician to consider allowable levels for transmit power. This ensures compliance with regulatory standards and optimizes the performance and reliability of the wireless link.

A) NFC protocol data rate

NFC (Near Field Communication) is designed for short-range communication and operates at a data rate suitable for close proximity interactions, making it irrelevant for establishing a point-to-point connection between buildings. Therefore, this option does not apply to the technician's needs in this scenario.

B) RFID frequency range

RFID (Radio-Frequency Identification) is used for tracking and identification purposes, operating within specific frequency ranges depending on the type of RFID. However, it does not pertain to establishing a wireless point-to-point connection for LANs, making this option incorrect.

C) Bluetooth version compatibility

While Bluetooth technology facilitates wireless communication, it is not suitable for point-to-point connections over longer distances, such as those required for connecting two buildings. Thus, Bluetooth version compatibility is not a relevant consideration for the technician in this context.

D) Allowable levels for transmit power

Considering allowable levels for transmit power is essential for ensuring that the wireless equipment operates within legal limits, minimizing interference with other devices, and achieving the necessary coverage and performance for the connection between the buildings. This aspect is critical for successful implementation.

Conclusion

The correct choice is D, as it directly addresses the requirements for establishing a wireless point-to-point connection between the two LANs. Options A, B, and C fail to provide relevant considerations for this specific scenario, emphasizing the importance of adhering to transmit power regulations for effective and compliant wireless communication.
