The primary objective of the initial pre-deployment meeting is to communicate the design decisions to the deployment team, ensuring they understand the design documentation.This alignment is crucial for the successful implementation of the WLAN infrastructure as per the design specifications.
The CWDP-305 Official Study and Reference Guide highlights the importance of clear communication during the deployment phase.

Comprehensive and Detailed Explanation:
The IEEE 802.11 standard does not mandate a specific calibration accuracy for Received Signal Strength Indicator (RSSI) and Signal-to-Noise Ratio (SNR) reporting across client devices. RSSI values are relative and can vary between different hardware vendors, as each manufacturer may implement their own scale and measurement methods. This lack of standardization means that RSSI readings are not directly comparable across different devices. Therefore, there is no specific value to which clients are required to be calibrated for RSSI and SNR reporting.
