This is clearly reflected in different solutions being developed by service providers, roaming operators and device manufacturers that aim to facilitate WLAN usage.</div> <br style="color: rgb(65, 65, 65); font-family: Arial, Helvetica, &quot;Arial Unicode MS&quot;, &quot;Trebuchet MS&quot;, sans-serif; " /> <div class="NLM_sec NLM_sec_level1" style="color: rgb(65, 65, 65); font-family: Arial, Helvetica, &quot;Arial Unicode MS&quot;, &quot;Trebuchet MS&quot;, sans-serif; "><span style="color: rgb(32, 84, 136); "><a name="_i4"></a></span> <div class="sectionInfo" style="overflow: hidden; "><div class="sectionHeading" style="float: left; font-size: 18px; "><h5 style="margin: 0px; color: rgb(51, 51, 51); text-rendering: optimizeLegibility; line-height: 18px; font-size: 12px; ">Originality/value</h5></div> <div class="sectionJumpTo" style="float: right; "></div></div> <span class="NLM_x">–&nbsp;</span>The ubiquity of WLAN services, ranging from campus networks to commercial hotspots and community WLAN services, requires a new approach for automatically locating and using services. The paper presents a service selection infrastructure that is independent of a user's current network attachment and location in a way that users can obtain information of a specific network (or any other service) without being required to be connected to a particular one. Information about networks and services are distributed in a way that allows for using this information offline, e.g. when still looking for appropriate network access.</div>
