What method might improve network performance when upgrading a wireless network?

1. Increasing the number of access points

2. Upgrading only the router

3. Using higher frequency bands

4. Implementing multiple SSIDs

The correct answer is: Increasing the number of access points

Increasing the number of access points is an effective method for improving network performance when upgrading a wireless network. By adding more access points, you can enhance coverage and reduce the load on any single access point, which helps alleviate congestion, particularly in environments with high user density or extensive coverage areas. This configuration allows more devices to connect simultaneously with less interference and better overall bandwidth distribution. In contrast, simply upgrading only the router may not provide significant performance improvements, especially in areas where coverage is lacking. Using higher frequency bands, such as 5 GHz, can improve throughput and reduce interference but may limit range. Implementing multiple SSIDs can help manage network traffic and user groups, but without additional access points, it may not address the underlying coverage or performance issues effectively. Thus, adding access points is typically a more comprehensive approach to enhancing the performance of a wireless network.
