问题 Because short messaging service is a kind of data communication, second generation wireless cannot support it. [br] Even on their way to destinations, travelers can easily surf Internet by 802.11 cards if there are ______.
选项
答案 mobile hot spots
解析 由题干中的on their way和802.11 cards定位到第六个小标题下首段前两句To exploit the real power of 4G, Beijing...standard 802.11 access points．此处应填入名词性成分。题干中的travelers与原文中的users同指；原文第二句中的this指代的是第一句的内容。所以空白处应填入mobile hot spots。
