Infrastructure, information wireless networking

Information systems—by which we mean an interrelated suite of communication and computation technologies—are the third infrastructure we consider. In addition to the spread of information services across the population, the other important development during the twentieth century was the advent of wireless information systems. First, the country was hardwired for telephony, and then systems of wireless telephony were built. First, the internet was built on a hardwired infrastructure. Now increasingly it is based on wireless networks. These trends point to a future in which information continues to be untethered from location. 

In addition to a wired network infrastructure, there is increasing utility to be found in a wireless network infrastructure, providing the advantage of mobility. Applications include wireless patient networks, voice-over Internet Protocol (IP) for mobile communications, and communication with handheld information terminals carried by each physician. A wireless infrastructure requires careful planning, with attention being paid to access points, data rates, and electromagnetic compatibility with medical devices. Current standards such as IEEE 802.11b allowing data rates of 11 Mbps facilitate the seamless coexistence of wireless and wired networks. The use of lower-spread-spectrum techniques in wireless applications reduces problems associated wit medical device interference.

Another alternative for mobile robotic applications consists in taking advantage from the Wireless Sensor Network paradigm as a complementary infrastructure allowing for acquiring additional knowledge aboutthe environment. The idea is to feed the robots with additional cyberphysical information that can be carried out by the WSN, which provides substantial support to the robotic system to accomplish its missions. As a consequence, the performance will naturally improve. As an illustrative example, a WSN can afford localization services for robots to support its navigation in an indoor environment, in a...
