Designing Cisco Wireless Enterprise Networks (WIDESIGN, legacy) — Question 4

Cisco 7925G phones are experiencing intermittent connectivity issues. The wireless survey reveals that the facility has no current coverage holes. The radios on the 2.4GHz channel have all been statically set to power level 1. Which two reasons could explain why the phones are having issues on this wireless network?
(Choose two.)

Answer options

• A. The phones are experiencing excessive co-channel interference.
• B. The phones only operate on the 2.4 GHz band when the power level is above 25 mW.
• C. The phones are not transmitting at the same power levels as the access points.
• D. The phones are experiencing delays of less than 30 ms within their coverage cell.
• E. The phones are receiving greater than -67 dBm RSSI on the 2.4 GHz band.

Correct answer: B, C

Explanation

The correct answers are B and C. Option B is correct because Cisco 7925G phones need a power level above 25 mW to operate effectively on the 2.4 GHz band. Option C is also correct as the phones may not be transmitting at the same power levels as the access points, leading to connectivity issues. The other options do not address the specific issues related to power levels and are therefore not valid explanations.
