The Wireless Path When Unwired Planet later currently Openwave wanted to create Internet access over a mobile phone they analyzed factors such as device memory capabilities wireless network connection and drop times device display and control characteristics and transfer speeds. They developed although some will argue GeoWorks developed HDML or Handheld Device Markup Language. Later Openwave joined with Nokia and others to found the WAP Forum now the Open Mobile Alliance. This group had the goal of creating a common standard for wireless Internet access. They largely took the features of HDML with some exceptions that frustrated the usability community and created WML Wireless Markup Designing the Mobile User Experience Barbara Ballard 2007 John Wiley Sons Ltd 200 APPENDICES Language as an XML language. This language proceeded from version to with version the apparent most common browser implementation.
