The CNT Books network described in Case Project 8-1 is expanding

1. One possible solution for connecting the building across the street with the existing building is to use a wireless bridge. This would involve installing a wireless access point in the building across the street and connecting it to the network infrastructure in the existing building.

Step-by-step explanation

• A solution for connecting the building across the street with the existing building is to install a wireless bridge. A wireless bridge is less expensive than hiring a service provider, and it can be installed quickly. This would allow for the connection, yet not require new wires to be run throughout the buildings, which could prove costly and inconvenient, especially if there are any renovations that need to be made in the future. 
• Another possible solution would be to lay fiber optic cable between the buildings. A drawback here would be that it would take time to dig up the street and lay the cable, and this might disturb traffic in the neighborhood.
• A simple wireless solution would allow the buildings to communicate with one another using a single channel. The connection could also be made with a single Ethernet cable. CNT has plenty of resources to make this connection and maintain it much more cost effectively than contracting out the work to an ISP.
