WiMAX與3G是目前無線行動寬頻接取技術中，最有可能成為主流的兩種技術。3G進入市場的時間較早，優勢在於具備強大的移動性。但是與其配合的終端裝置大部分為無法執行太多任務的手機，因此在內容服務上並無法獲得良好的發展。另一方面，WiMAX以低成本、高傳輸速率、良好行動性為訴求，緊隨著WiFi的成功之後開始進入無線行動寬頻接取服務的市場。不過一般預期WiMAX早期的應用終端裝置以行動性不高的筆記型電腦為主，並逐漸往高行動性的手持裝置發展。本研究主要探討的主題在於，當WiMAX以新進者的形態進入3G已存在的無線行動寬頻市場時，這兩種相近的技術產生何種競爭與合作的關係。
本研究以產業資料及文獻回顧整合出的探討角度來探討WiMAX與3G可能的競合狀況。另外，本研究也採取專家意見法來獲得實務業界對WiMAX與3G競合狀況的看法，以補足僅以文獻與次級資料探討本研究主題的不足。本研究檢視與整理WiMAX與3G在技術上的表現後發現，WiMAX在技術上的表現在目前及未來的兩三年之間都優於3G的相關技術標準。而藉由系統產品的特性與網路外部性、標準競爭與數位匯流的角度來探討WiMAX與3G可能的市場表現特性與競爭合作關係後也發現，WiMAX相對於3G具有低成本的特性，但3G在安裝基礎、線路普及率、全球工作頻段的一致性上，則有WiMAX未能具備的絕對優勢。因此何者能成為市場上主流的無線行動寬頻接取技術，尚未能有明確的定論。
WiMAX與3G在一開始的關係是合作大於競爭，而隨著WiMAX進入市場的時間越長，兩者之間的關係也由合作慢慢轉為競爭。而主要影響WiMAX與3G競爭關係的關鍵變數有四個：政府對WiMAX發展的態度、快速建立消費者期望的能力及對終端裝置產品發展趨勢的掌握、無線行動寬頻服務需求的成長狀況。WiMAX與3G 何者能確實影響或掌握四項關鍵變數的變化，將能真正成為市場上無線行動寬頻接取技術的主流。 / Among all kinds of broadband wireless access technologies, WiMAX and 3G are the 2 most potential candidates to dominate the future broadband mobile date service marrket. On the one hand, 3G moves into the market earlier and has the advantage of high mobility and popular existed 2G, 2.5G subscribers as bases. However, the content service on 3G doesn’t get prospered due to the complemental terminal devices comprise mostly handheld phones which aren’t capable of performing complicated tasks. On the other hand, WiMAX tries to follow the success of WiFi, and positions as the low cost, high data rate, and metropolitan area mobile solution in the broadband mobile data service. The most possible complemental terminal devices for WiMAX in early stage are notebooks which don’t provide high mobility, and will gradually migrate to handsets with high mobility then. This study tried to figure out the competition and cooperation between WiMAX and 3G when WiMAX as a new comer move into the broadband mobile data service market with 3G already existed in it.
This study discussed the possible competition and cooperation between WiMAX and 3G based on the industrial data and related literatures. Professions interviews were also included to supplement with the practical viewpoint of telecom operators. From the technical perspective, WiMAX has better performance and will lead 3G for next 2 to 3 years. From the perspective of systematic product, network externalities, standard competition, and digital convergence, WiMAX surpasses 3G in lower cost, and 3G is superior to WiMAX in larger installed base, potential subscribers and consistent international radio band. As a result, there is no clear conclusion can be made which of WiMAX and 3G can dominate the broadband mobie datea service market in the future.
WiMAX will cooperate more than compete with 3G in telecom operators at its early movement into the market. As the time pass by, WiMAX will compete more than cooperate with 3G. The four critical variables to influence the competition between WiMAX and 3G are: the government attitude to WiMAX development, the ability to establish the consumers’ expectation, response to mobile terminal devices trend, and the growth of the wireless mobile broadband demand. Either WiMAX or 3G has the potential to be the mainstream in the wireless mobile broadband market provided that which can influence or respond to the four variables above better.
