'GIS on the fly' to realize wireless GIS network by Java mobile phone

摘要

Java cellular phone has arrived in the marketplace as the latest device of a mobile gear. The gear is very compact, allowing 10KB for Java program size and 5KB for data size. Although small in size, it features innovative computer system architecture. Java program can be sent dynamically to the gear in a streaming manner over wireless network. In addition, compared to conventional mobile computers, Java cell phone is very cheap both in hardware price and in communication cost. Java cell phone has an enormous potential as a mobile gear. In this paper, we discuss our trial of constructing a extensive wireless GIS network by utilizing Java cell phone as a GIS terminal.
