Local Area Networks
With a local area network, or LAN, the focus is on providing the same secure communications as with a WAN, just on a smaller geographical area. This type of telecommunications network offers phone, data, and Internet capability within an enclosed setting, and from a limited number of devices connected to the network. One example would be a hotel, where the phones and Internet access are all routed through a network located within the hotel. Connections to larger networks is only achieved by going through the LAN first.
