隨著網路科技日新月異的成長,再加上網路上的娛樂與休閒資訊越來越發達,使得人們對網路的依賴程度相對地增高,對於「隨時隨地可上網」的需求,也逐漸增加,無線上網是未來發展的趨勢。二十一世紀為行動無線通訊快速發展的年代,若要達到行動通訊,可隨時隨地上網接收信息的無遠境界,唯有將第二代的泛歐式系統(GSM)、2.5 代的整合封包無線電服務協定(GPRS)、第三代行動通訊技術(3G)及WLAN不同的系統整合在一起,可依照不同的地形、街道結構、建築物而有不同的系統服務,這樣不但可快速的達到訊號傳送,也可以減少不必要的信號干擾。
本篇論文首先說明整個無線行動通訊的概況;其次再介紹無線行動通訊技術,包括GSM、GPRS、3G以及WLAN的介紹;最後著重於行動通訊系統(GSM/GPRS/3G)與無線區域網路(WLAN)的整合研究,以及都會區無線電波涵蓋率的評估,作為增設3G/WLAN系統基地站台的參考。
The growth of new network technology nowadays, along with internet entertainment has been explosive since it started. Leisure information are getting more and more developed, cause level of dependency to advance relatively in networking. Regarding “may access the net anytime and anywhere” demand also increases gradually. Wireless surfer is quite tendency in future development regarding wireless. The 21st century for wireless communication was fast developed, if we have to achieve motion communication which may be able to access the net anytime and anywhere capability. There is a only way which is 2nd generation of pan-western-style system (GSM), 2.5 generation of conformity, Gift radio service agreement (GPRS), 3rd generation motion mechanics of communication (3G) and the WLAN different conformity in same communication system. It may defer to different terrain, street and building structure to have the different service. It’s not only just provide fast signal transmission, it may also reduce the nonessential meaconing.
This paper first explains the entire wireless mobile communication survey; Next introduces the wireless motion mechanics of communication, including GSM, GPRS, 3G as well as WLAN introduction; Finally emphatically in the motion communication system (GSM/GPRS/3G) with the wireless region network (WLAN) conformity research, as well as can the area radio wave coverage appraisal, the achievement additionally build the 3G/WLAN system base platform the reference.
