A hospital wireless environment was designed with these characteristics: - RF coverage - better than -67 dBm in the 5 GHz spectrum - RRM be used for DCA and TPC in the 2.4 GHz band - RRM be used for…
The correct answer is D. TPC drastically reduces Tx power in the 2.4 GHz band. The Cisco Aironet 3800 Series APs support mGig, which allows for higher throughput over existing cabling. However, the maximum cable length that supports 5G operation is limited by the quality of the cable and signal attenuation. Category 5e cabling can support 5G operation up…
Question
A hospital wireless environment was designed with these characteristics:
- RF coverage
- better than -67 dBm in the 5 GHz spectrum
- RRM be used for DCA and TPC in the 2.4 GHz band
- RRM be used for DCA and TPC in the 5 GHz band
After deployment, why do many of the legacy 802.11b/g devices have difficulty maintaining connectivity?
Options
- AExcessive co-channel interference in the 2.4 GHz band exists.
- BExcessive overlapping channels in the 2.4 GHz band exists.
- CTPC drastically increases Tx power in the 2.4 GHz band.
- DTPC drastically reduces Tx power in the 2.4 GHz band.

Explanation
The Cisco Aironet 3800 Series APs support mGig, which allows for higher throughput over existing cabling. However, the maximum cable length that supports 5G operation is limited by the quality of the cable and signal attenuation. Category 5e cabling can support 5G operation up to a length of 130 meters, which is within the acceptable range for maintaining the required signal integrity for 5G speeds.
