Best Practices for Deploying an 802.11b Wireless Infrastructure

A

The best practice for deploying an 802.11b wireless infrastructure is to allocate nonoverlapping channels to access points that are in close physical proximity to one another. This is because 802.11b operates in the 2.4 GHz frequency band, which has only three nonoverlapping channels available (channels 1, 6, and 11). If access points are placed too close to one another and set to the same channel, interference can occur, leading to poor performance and connectivity issues. By allocating nonoverlapping channels, the access points can operate simultaneously without interfering with each other's signals.

Disabling TCP (Answer B) is not a recommended practice for deploying wireless infrastructure as it is a crucial protocol for the proper functioning of the internet and other networked applications.

Configuring access points to provide clients with a maximum of 5 Mbps (Answer C) is not a best practice, as it limits the data transfer rate, which can result in poor network performance and low user satisfaction.

Setting the maximum data rate to 54 Mbps on the Cisco Wireless LAN Controller (Answer D) is also not a best practice, as it is not optimized for 802.11b and can lead to unnecessary interference and slower network speeds. It is best to set the data rate based on the specific needs of the network and the capabilities of the access points and client devices.

In summary, allocating nonoverlapping channels to access points in close physical proximity is the best practice for deploying an 802.11b wireless infrastructure.
