Book from the Basics series of the Cisco Press publishing house. This series introduces users who professionally deal with networks to new technologies, discussing network topologies, examples of deployments, protocols and management techniques. In the face of increased data rates and falling prices, the benefits of installing wireless local area networks (WLANs) have become measurable. Now employees are not chained to their desks, nor does it hamper the physical expansion of the company. Implementation of WLAN can significantly increase productivity and bring big savings, allowing you to connect networks located in different buildings. However, as more and more companies are considering the use of WLAN, a lot of problems related to their design, implementation and management emerge to the light of day.
