350-401 Question 17
Select 3A company is designing a wireless network for its new office building. The network must support high-density environments, such as conference rooms and auditoriums, while ensuring minimal co-channel interference. Which design principles should be applied to achieve these goals?
- A
Use non-overlapping channels to separate adjacent access points
- B
Deploy access points with maximum transmit power to ensure wider coverage
- C
Increase the number of access points to handle higher client density
- D
Perform a site survey to identify sources of interference and optimal AP placement
- E
Employ directional antennas to focus the wireless signal in specific areas
Show answer and explanation
Correct answers: A, D, E
Explanation
High-density wireless network designs require careful planning to ensure sufficient capacity and minimal interference. Using non-overlapping channels, conducting a site survey, and employing directional antennas are key principles to achieve these goals. Maximizing transmit power or randomly increasing the number of access points without planning can lead to degraded performance due to interference.
- A. Correct.
Using non-overlapping channels helps reduce co-channel interference, improving network performance in high-density environments.
- B. Incorrect.
Deploying access points with maximum transmit power can cause excessive interference and is not suitable for high-density environments.
- C. Incorrect.
Simply increasing the number of access points without proper planning can lead to channel overlap and increased interference.
- D. Correct.
Performing a site survey ensures optimal placement of access points and helps identify potential sources of interference, which is critical for high-density designs.
- E. Correct.
Directional antennas can help focus wireless signals in specific areas, reducing interference and improving coverage in high-density spaces.
