阅读下列说明,回答问题1至问题3。
【说明】
去年底某大型企业集团的财务处经过分析发现,员工手机通话量的80%是在企业内部员工之间进行的,而90%的企业内部通话者之间的距离不到1000m。如果能引入一项新技术降低或者免掉内部员工通话费,这对集团来说将能节省很大一笔费用,对集团的发展意义相当大。财务处将这个分析报告给了集团的总经理,总经理又把这个报告转给了集团信息中心主任李某,责成他拿出一个方案来实现财务处的建议。
李某找到了集团局域网的原集成商A公司,反映了集团的需求。A公司管理层开会研究后命令项目经理章某积极跟进,与李某密切联系。章某经过调研,选中了一种基于无线局域网IEEE802. 11n改进的新技术“无线通”手机通信系统,也了解到有一家山寨机厂家在生产这种新技术手机。这种手机能自动识别“无线通”、移动和联通,其中“无线通”为优先接入。经过初步试验,发现通话效果很好,因为是构建在集团现有的局域网之上,除去购买专用无线路由器和这种廉价手机之外,内部通话不用缴费。而附近其他单位听说后,也纷纷要求接入“无线通”,于是章某准备放号并准备收取这些单位适当的话费。
但等到“无线通”在集团内部推广时,发现信号覆盖有空白、噪声太大、高峰时段很难打进打出,更麻烦的是当地政府的主管部门要他们暂停并要对他们罚款。此时章某骑虎难下,欲罢不能。

【问题1】
造成这样局面的可能原因是什么章某在实施“无线通”时可能遇到的风险有哪些

It is hardly surprising that clothing manufacturers (生产商)follow certain uniform standards for various features(特征)of clothes. What seems strange, however, is that the standard adopted for women is the opposite of the one for men. Take a look at the way your clothes button. Men’s clothes tend to button from the right, and women’s from the left. Considering most of the world’s population---men and women---are right-handed, the men’s standard would appear to make more sense for women. So why do women’s clothes button from the left?

History really seems to matter here. Button first appeared only on the clothes of the rich in the 17th century, when rich women were dressed by servants. For the mostly right-handed servants, having women’s shirts button from the left would be easier. On the other hand, having men’s shirts button from the right made sense, too. Most men dressed themselves, and a sword drawn from the left with the right hand would be less likely to get caught in the shirt.

Today women are seldom dressed by servants, but buttoning from the left is still the standard for them. Is it interesting? Actually, a standard, once set, resists change. At a time when all women’s shirts buttoned from the left, it would have been risky for any single manufacture to offer women’s shirts that buttoned the right. After all, women had grown so used to shirts which buttoned from the left and would have to develop new habits and skills to switch. It would be weird for them to button from the right, since anyone who noticed that would believe they were wearing men’s shirts.
