 incumbent telcos. Hong Kong, Singapore, Korea, and Japan have also dis- played interest in mesh networks, and wireless mesh networking is predicted grow as the first networks deployed demonstrate real-world benefits. Mesh networks are also of great interest to local communities and nonprofits in the developing world, particularly those interested in planning, deploying, and maintaining a local, sustainable network infrastructure to enable voice and data communications, both locally and on the Internet. University and enterprise cam- puses seeking to extend their WLANs outdoors are also good candidates. National Taiwan University and Edith Cowan University in Western Australia are early examples. By using a wireless mesh network, Edith Cowan University offers voice services to students, who can use Wi-Fi/cellular handsets to make intranetwork Wi-Fi calls on campus and roam to cellular for off-campus calls. Wireless Micromesh Networks One of the most important applications of mesh networks is their ability to dynam- ically support and make possible large-scale sensor networks (e.g., those that use RFID, telemetry, and control applications) that collect real-time data. Wireless micromeshes eliminate the need to wire every node and thus provide the greatest degree of flexibility possible in sensor/control networks. A micromesh network designed for short range (i.e., up to 300 feet [100 m] between any two nodes). This class of mesh network is characterized by long battery life, relatively low data rates, and good tolerance for latency. Core applications of micromeshes include the following, among many other industrial, commercial, and residential applications: Physical security-Micromeshes enable access control, monitoring, alarms, and other forms of physical security. Environmental sensing-Micromeshes can sense shock, vibration, ther- mal, optical, chemical, biological, and other environmental factors. Building automation-Micromeshes can be used in a building to automate HVAC, security, energy management, and SO on.
