When designing a Wi-Fi network, it is important to consider factors such as coverage, capacity, interference, and security. To improve the Wi-Fi network of an organization, several new coverage cells may be required. There are different standard designs that can be used to achieve this goal. Let's discuss the two recommended designs:

A. 5GHz provides increased network capacity with up to 23 nonoverlapping channels. The 5GHz frequency band is less congested than the 2.4GHz band and provides higher network capacity. It has up to 23 nonoverlapping channels, which means that adjacent access points can use different channels without interfering with each other. This design is recommended because it allows for more access points to be deployed without causing interference.

B. 5GHz channel selection requires an autonomous access point. An autonomous access point is a standalone device that can be configured individually. It allows for more control over channel selection and other settings. In contrast, a lightweight access point requires a wireless LAN controller (WLC) to manage its configuration. This design is recommended because it provides more flexibility in channel selection.

C. Cells that overlap one another are configured to use nonoverlapping channels. When designing a Wi-Fi network, it is important to avoid overlapping cells on the same channel. Overlapping cells can cause interference and reduce network performance. This design is recommended because it ensures that adjacent cells use different channels to minimize interference.

D. Adjacent cells with overlapping channels use a repeater access point. A repeater access point is used to extend the coverage area of an existing cell. It receives and retransmits signals from the parent access point. This design is recommended when adjacent cells have overlapping channels and there is no alternative channel available. However, it should be noted that repeater access points can reduce network performance and should be used sparingly.

E. For maximum throughput, the WLC is configured to dynamically set adjacent access points to the channel. The wireless LAN controller (WLC) is a device that manages and controls access points in a centralized manner. It can be configured to dynamically set adjacent access points to the same channel for maximum throughput. However, this design can cause interference and should be used with caution.

In summary, the two recommended standard designs for improving the Wi-Fi network of an organization are:

  1. Deploying 5GHz access points with nonoverlapping channels and using an autonomous access point for more control over channel selection.

  2. Configuring adjacent cells to use nonoverlapping channels and using a repeater access point as a last resort when no alternative channel is available.
