Wireless LAN is a complementary service offering for mobile operators. The Ericsson Mobile Operator WLAN solution combines the wide-area benefits of second- and third-generation mobile systems, including unlimited roaming and mobility, with additional throughput and capacity in indoor hot-spots via wireless LANs. The solution gives broadband mobile public access to the Internet and to corporate intranets from relatively little additional investment.

The authors present WLAN as a complement to GPRS and UMTS and explain the market drivers of the solution. They describe the Ericsson Mobile Operator WLAN – Release 1 in detail and give an overview of ongoing standardization.
