Abstract:	現今網路與無線通訊系統，皆已經演進至高速傳輸世代，漸漸引領人們進入無距離的生活。由於無線通訊系統的進步，多數以通訊系統為軸心的技術，可以不被拘限在有線網路系統的限制，以無線網路來建置的系統，有非常多的優點，跨越地形上的障礙，克服通訊距離，減少纜線的鋪設，以台灣各處可見的監控系統而言，不論交通、社區或校園，改用無線網路來建置，建置系統時的便利與節約，在未來都是被關注的焦點。本論文在台灣大學地區實際測試針對已無線網路系統去建置無線校園監控系統之可行性，採用目前剛營運之WiMAX，以及現有的HSDPA(3.5G)、EDGE(2.5G)等技術透過Skype軟體來同時傳輸影像、VoIP，本論文最後會總結此三種無線網路技術傳輸後之結果與討論。 Internet and wireless communication system have been evolved into the new generation of high-speed transmission and people at anywhere and any time can retrieve they need information and message. Due to the development and advancement of wireless communication, many technologies utilizing communication as their core technologies will not be restricted and confined in the wired line network systems. In the installations of wireless communication system, it has many advantages such as to reduce the terrain barrier, to conquer the communication distance restriction and to reduce the amount of cable installations. In Taiwan for its existing and ubiquitous installed monitoring systems, if in their future new systems installations, no matter they are for traffic, community or campus, and if they are installed with wireless monitoring networks then they will become the focal attentions in the convenience and its cost effectiveness with the wireless systems installations. In this report we study the feasibility of the installation of wireless campus monitoring network through the field trials in the campuses of National Taiwan University and National Taiwan University of Sciences and Technology. We adopt the just in service WiMAX and the available HSDPA (3.5G), EDGE (2.5G) technologies to proceed in the system performance test when video, VoIP signals are simultaneously transmitted through the system by using Skype software. The transmission of HRV (Heart Rate Variation) through FTP format with these three systems is also studied. The resulting system performance and their characteristics of using WiMAX, HSPDA and EDGE in the transmission of video, VoIP and HRV are summarized and compared. With these test data and results it may provide some valuable reference data to the system designers and service providers when they are considering the installations of wireless surveillance system in the university campus.
