Besides LAN, WAN communication is also important to a company's life. Getting and keeping touch with the customers is the base of every business. May those customers be in the next street or in a distant continent (Figure 1). E-mails and phonecalls directed to them are directed out of the office, out of the company's LAN, so it requires WAN.
