These networks allow individual computers to talk with other computers, access centralized programs and data, and navigate the Internet. Each has method of access has advantages and specific use cases.
Small businesses will often use a single WAP device and a router. This installation is fast and easy with no special requirements. Larger company networks, where there may be geographic dislocations making more than one WAP device necessary, will most likely require an RF study for the areas to be covered.
The company may also need greater control about which devices may access the network and, in some cases, guarantee that a specific computer connects to the network in a specific way.
For example, systems accessing financial data may be limited to a certain room or desk location. High level authorizations may only be allowed from the office of a member of the executive team. Access control of this nature can be accomplished with a physical LAN.
Most companies will use a combination of physical LAN and WAPs. Whether or not the network suffers bottlenecks, outages or slow response times is most often attributed to poor Physical Architecture.
