CCNP Wireless FAQ: Performing Site Surveys
Q1. A physical site survey includes determining how to route cable from the wireless equipment to the antenna. True or false?
Figure: Antenna-Mounting Location Examples
Q2. Before you perform a physical site survey, you should know how high above the ground your antennas need to be mounted. True or false?
Q3. If there is already wireless equipment operating on a building, you will first discover it during your RF site survey. True or false?
Q4. Minimizing the distance between your wireless equipment and your antenna system is important. Why?
Q5. If power lines run near a roof edge, is it okay to mount your antenna near that roof edge? Why or why not?
Q6. What is the biggest consequence from installing a wireless system in an area with a high noise level?
Q7. If you have a wireless protocol analyzer, you do not need a wireless spectrum analyzer. True or false?
Q8. If the operation of license-free equipment causes interference to the operation of licensed amateur radio equipment, the operator of the license-free equipment is responsible for correcting the interference problem. True or false?
Q9. The length of the spectrum analyzer sampling interval doesn’t tell you anything about the level of RF interference in a particular area. True or false?
Q10. In general, the higher the signal-to-noise ratio on a wireless link, the higher the wireless throughput. True or false?
Q11. What part of a point-to-multipoint wireless network is the most vulnerable to a high noise level? Why?
Answer: The hub site access point receiver of a point-to-multipoint network is the most vulnerable to a high noise level. Noise reduces the signal-tonoise ratio, which reduces the size of the coverage area and the throughput of the network.
