If the amplifier in Question 4 has a noise figure of 10 dB but a gain of 0 dB, what is the total noise figure of the cable, amplifier, and filter in series?
Response:
You are site surveying a network for VoWiFi. You have positioned an AP for a manual survey and are moving away from the AP with a phone in
Survey Mode in your hand and you are reading the RSSI value of the signal received from the AP. You have previously determined that the noise
floor was approximately -94 dBm on this floor of the building. The phones documentation does not specify a recommended RSSI or SNR value for
best performance.
Based on the information provided and the type of device (VoWiFi phone) you are deploying, what minimum RSSI should you plan for in all areas
you are monitoring and where VoWiFi service is desired?
Your customer is using PSK as their only authentication. They have an industry requirement to move to a stronger solution. Your recommendation
is to move to a certificate-based type of authentication where both the client and server require certificates. Which EAP type would be the best fit?
You deployed an AP and installed its antenna, and you now need to set the AP transmit power. Given a desired EIRP of 21 dBm, and an antenna
gain of 5.85 dBd connected through 25 feet of cable with a loss specification of 4 dB/100 feet.
Assuming that there is no significant loss from the connectors, what should be the transmit power level for this AP?
