The House of Representatives will begin installing a WiFi network in January, creating a number of wireless hotspots in cafeterias. The goal is to have the 802.11n network cover the four House buildings and the U.S. Capitol building, which includes hearing rooms and member offices. The only WiFi hotspots today in the House are various member-operated networks that are not monitored. Most wireless Internet users on Capitol Hill rely on 3G signals that are often unreliable. The House has been leery about WiFi networks over security concerns. Plus the 505,000 square foot, multi-building campus, complete with marble walls make a WiFi network a challenge. Article
