When designing a high-density wireless network for a large auditorium in an enterprise environment, which of the following strategies is most effective in managing co-channel interference (CCI)?
- A . Deploying omnidirectional antennas at maximum power settings
- B . Utilizing a high-density deployment with microcell architecture
- C . Spreading the access points evenly across the available spectrum without considering user density
- D . Increasing the minimum data rate for the wireless LAN
B
Explanation:
In a high-density environment such as a large auditorium, managing co-channel interference (CCI) is crucial for maintaining optimal wireless performance. Utilizing a high-density deployment with microcell architecture involves deploying a larger number of access points with lower transmit powers and smaller coverage areas. This approach allows for a more granular control of the RF environment, reducing the overlap between coverage cells and thereby minimizing CCI. It contrasts with deploying omnidirectional antennas at maximum power settings, which can exacerbate CCI by extending the range of each access point’s signal and increasing the likelihood of overlap. Increasing the minimum data rate does not directly address CCI, although it can improve overall network efficiency. Lastly, simply spreading access points evenly without considering user density fails to account for the variable demand within the auditorium, potentially leading to areas of high CCI and poor performance.
When configuring alert rules based on network conditions, what factor should be considered for effective alerting?
- A . Integration with ITSM tools
- B . Compliance with industry standards
- C . Notification frequency
