<p>&nbsp;<b style="text-align: justify;"><span style="font-size:10.0pt;&#10;line-height:115%;font-family:&quot;Times New Roman&quot;,serif;mso-fareast-font-family:&#10;&quot;Times New Roman&quot;">Today, with continuing improvements in WiFi/802.11 technology, including higher bandwidth protocols, IP based networking and faster roaming between access points, users are finally able to use WiFi to construct a reliable mobile wireless communication system in industry that takes advantage of all the latest innovations to deliver substantial cost savings, easier set up and maintenance, and greater operational efficiency.</span></b></p> <p class="MsoNormal" style="text-align:justify;line-height:107%"><b><span style="font-size:10.0pt;line-height:107%;font-family:&quot;Times New Roman&quot;,serif">When wireless links are included in industrial network, reliability and timing requirements are stringent and more difficult to meet, due to the adverse properties of the radio channels. In this paper, we thus discuss some key issues coming up wireless industrial communication systems :1)fundamental problems like achieving timely and reliable transmission despite channel errors; 2) the usage of existing wireless technologies for this specific field of applications; and 3) the creation of hyid systems in which wireless stations are included into existing wired systems.<o:p></o:p></span></b></p>
