Dot是一个完整的信号天线，外形有点像烟雾探测器。它可以作为蜂窝网络的一种延伸附着在墙壁或者天花板，为室内环境带来语音和数据信号。<BR><BR>在一些需要移动服务的场所，信号的覆盖率及容量十分缺乏。目前很多公司提出解决方案，而爱立信希望借助Radio Dot进军这一市场。例如，到2014年末，AT&T计划建设4万个小蜂窝站点，布置1000个分布式的天线系统，以增强其3G和LTE网络服务。据称这些服务的主要目标是室内。</P> <P><A href="http://www.oecr.com/data/attachment/portal/201309/29/105147ffkrze9rbt2en9zn.jpg" target=_blank><IMG src="http://www.oecr.com/data/attachment/portal/201309/29/105147ffkrze9rbt2en9zn.jpg"></A></P> <P>AT&T小蜂窝网络服务副总裁戈登·曼斯菲尔德(GordonMansfield)表示：“我们花了20年建设首批5万个蜂窝站点。我们在3年内还要再建设4万个。”作为小蜂窝<a href="http://bbs.oecr.com" target="_blank" class="relatedlink">论坛</a>的主席，他认为移动网络设计下一个阶段关注的是容量，而非覆盖率。小蜂窝网覆盖的面积或许只是宏蜂窝的一少部分，但它们的网络容量相等。<BR><BR>爱立信的Radio Dot无疑是AT&T建设新网络时不错的选择。它关注的是室内网络服务，不过距离商业化还有一年时间。<BR><BR>爱立信网络部门主管约翰·韦伯(Johan Wibergh)表示，Radio Dot灵活性强，而且价格低廉，能够提高办公大楼和居民区的网络覆盖率和容量。但它不会用于较大的室内公共场合，如体育馆、购物中心。<BR><BR>值得一提的是，个人购买Radio Dots并在家里使用的可能性不大，因为它是针对办公大楼、大学校区的<a href="http://b.oecr.com/company" target="_blank" class="relatedlink">企业</a>级解决方案。Radio Dots系统包括一个基站，所谓的基站是一个接收运营商信号的蜂窝天线，它通过网络线缆把信号传输给互联的Radio Dots。Radio Dots支持以太网供电，所以不需要独立电源；每个Radio Dots的重量只有0.7磅。<BR><BR>爱立信表示，Radio Dots系统的蜂窝数据传输速度可达150Mbps，足以支持4G LTE网络，而且它很容易借助升级支持更快的速度。爱立信称，Radio Dots系统支持当前所有的蜂窝电话技术，也能同时支持多个运营商。当然，具体实施方式还要依赖用户和运营商的合约。<BR><BR>据悉，第一批商用化Radio Dots有望于2014年下半年上市。</P> <DIV><FONT color="#808080" size=2><IMG src="http://www.oecr.com/xwb/images/bgimg/icon_logo.png">
