Wireless Location Based Services (Wi-LBS)

The needs and demands on location information have arisen rapidly. With the advancement of mobile computing technologies, many researches and studies have been conducted in providing reliable location information solution. Location based information has become an important resource for mobile users especially in giving direction or locating places. Wireless Location Based Services (Wi-LBS) highlight this scenario by explaining the application and usage of the LBS in wireless environment. Wi-LBS is introduced with respect to providing wireless method in locating places within UTP campus instead of referring to static map. The objective of this research is to integrate GIS with MMS technology as a system called Wireless Location Based Services. It is mainly focused on applying GIS elements in providing location information by utilizing the advancement of today's wireless handheld devices. Users will request for location by sending short messages using their mobile phones to the WiLBS system and the system will reply back sending the location information containing pictures and direction. Rapid Application Development (RAD) is used as the methodology in designing the system of Wi-LBS. This research also details the study on Multimedia Messaging Service (MMS) that covers the sending of picture messages from Wi-LBS to mobile phones and system's function in responding to the users' requests. Various references and studies have been done regarding the successful LBS applications implemented in foreign country that leads to the interest of doing the research on LBS implementation in this country. The result from the research will be the proposed framework for Wi-LBS, the discussion on the GIS and MMS as well as the system of Wi-LBS. This study proved that Wireless Location Based Services has great potential to be commercially implemented with the growth of wireless application nowadays as today's community is eager of getting more services from wireless system

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

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. 1
