以日韩经验来看宽带行动上网服务的成功因素与发展契机

探讨日韩宽带行动上网的成功因素,发现服务内容个人化可增加消费者使用服务意愿,政府政策的大力支持有助于宽带行动上网的普及,优惠费率会吸引消费者转换3G码号及提升使用宽带行动服务的意愿。最后提出台湾3G和WiMAX业者建议。     

WiMAX技术及其在固定电信网应用的探讨

通过案例分析了WiMAX技术提供的多种应用方案和演进路线，认为WiMAX与3G等现有及其演进技术是相辅相成的，提出了要解决WiMAX在推广应用过程中存在的技术问题，抓住该技术在个人家庭用户市场、IP语音业务市场、传输承载市场和集团客户市场的发展机遇。     

无线通信技术热点及发展趋势

由于无线通信网络存在的带宽需求和移动网络带宽不足的矛盾,用户地域分布和对应用需求不平衡的矛盾以及不同技术优势和不足共存的矛盾,因此,决定了发展无线通信网络需要综合运用各种技术手段,从全局和长远的眼光出发,采取一体化的思路规划和建设网络。发挥不同技术的个性,综合布局,解决不同区域、不同用户群对带宽及业务的不同需求,达成无线通信网络的整体优势和综合能力。对此,我国政府管理部门也应该积极为运营商配备充足的频谱资源,为其综合规划提供有力的支撑和保障。     

Analyzing the Integration of WiMAX and Wi‐Fi Services: Bandwidth Sharing and Channel Collaboration

Several emerging studies have focused on the pricing issue of bandwidth sharing between Wi‐Fi and WiMAX networks; however, most either concentrate on the design of collaborated protocols or figure out the issue without the overall consideration of consumer preferences and contract design. In this study, we explore a wireless service market in which there are two wireless service providers operating Wi‐Fi and WiMAX. One of the research dimensions given in this study is whether wireless service providers implement bandwidth sharing, while the other is whether they make decisions individually or jointly. By involving consumer preferences and a wholesale price contract in the present model, we find that bandwidth sharing would benefit a WiMAX service provider, yet a Wi‐Fi service provider would make no significant savings under a wholesale price contract. In addition, the profit of a WiMAX service provider may increase with Wi‐Fi coverage when bandwidth sharing has been implemented but decrease with Wi‐Fi coverage when both wireless services operate without bandwidth sharing. Furthermore, the WiMAX service provider allocates more capacity when the average usage rate increases, but lowers the expenditure of capacity when the average usage rate is too high.
