When designing a wireless network for voice deployment, it is important to consider the cell overlap. Cell overlap refers to the amount of overlap between adjacent wireless access point (AP) coverage areas. Too much overlap can cause interference and degrade the quality of the wireless signal, while too little overlap can result in coverage gaps and poor connectivity.

To determine the appropriate cell overlap for a wireless voice deployment, Cisco recommends measuring the edge of the cell at a signal strength of -67 dBm or below. This signal strength provides adequate coverage while minimizing interference with adjacent cells. Therefore, option A is the correct answer.

Option B, which recommends measuring the edge of the cell below 35 RSSI (Received Signal Strength Indicator), is not a recommended Cisco measurement. RSSI is a relative measurement of signal strength and can vary depending on factors such as distance and obstacles between the AP and the client device.

Option C, which suggests that the measurement should be done on the 2.4-GHz band, does not provide enough information to determine the appropriate cell overlap. The appropriate cell overlap can vary depending on the frequency band being used, but the recommended signal strength of -67 dBm applies to both the 2.4-GHz and 5-GHz bands.

Option D, which recommends deploying one AP per 3000 square feet, is a general guideline for AP density but does not provide information on cell overlap. The appropriate cell overlap can vary depending on factors such as building materials, client density, and network capacity requirements.
