上海智慧城市建设中公共WLAN热点的空间分析与检讨

Building a smart city:a spatial analysis and review of WLAN hotspots in metropolitan Shanghai

在当前移动信息时代,无线城市、移动城市、智慧城市等各种新的城市形态不断涌现,但迄今对这些城市演变态势的空间认知还十分缺乏。本文试图探讨智慧城市建设中无线基础设施在城市内部布局的差异问题及可能带来的负面效应。以上海为例,采用上海移动的公共无线局域网(WLAN)热点数据,运用GIS方法进行空间分析,并揭示无线网络接入设施的空间分布规律和态势。结果发现,尽管无线接入设施在空间上迅速扩展,但仍没有缩小邻里之间的差异,空间数字鸿沟依然存在,并可能有扩大的趋势。最后,为当前无线城市和智慧城市发展与规划提供一些有益的政策建议。

In the current era of mobile telecommunication, wireless city, mobile city, smart city, and other kinds of new urban forms are emerging, but we know little about the evolution of these new urban spaces. This article explores the spatial disparities of wireless infrastructure in metropolitan area and reveals its adverse effects. It analyzes the spatial distribution of wireless access facilities by GIS technique, using the data of Shanghai CMCC's wireless local area network(WLAN) hotspots. Despite the rapid expansion of wireless access facilities in the city, disparities between neighborhoods have not been reduced. The spatial digital divide still exists and may have a tendency to expand. Finally, some planning and policy recommendations for wireless city are proposed.
