This article describes some recent developments in technology and in the communications industry that have brought mobile data within the reach of virtually any public safety operation, even those far-removed from populous areas.
Abstract
For smaller communities where private industry has not developed the necessary communications infrastructure, as well as for agencies that work in isolated areas, mobile data capability has been rare. Now, however, there is an alternative for agencies that operate in all but the most remote environments. MeshNetworks was brought to the market in 2003. It uses a Mesh-Enabled Architecture (MEA) device that functions both as an access point and as a repeater for wireless communication. In a typical MEA public safety system, a local government would install MeshNetworks Wireless Intelligent Access Points (IAP's) at fixed locations within their area of operations, such as light poles, water towers, public buildings, and other sites where the agency has rights and access. The IAP's would have access to a reliable hardwired power supply (with a battery backup); it would supply network coverage over a mapped area. The carrying capacity of the network can be expanded by the use of wireless routers that are also installed at fixed locations to assist in managing the flow of data. Besides serving as relay stations for network data, the fixed IAP's and wireless routers serve as reference points to triangulate the precise locations of wireless clients on the network. Each wireless client also serves as a relay station, extending the scope and connectivity of the network to the limit of its access point. MeshNetworks has a demonstration network established in the Orlando metropolitan area.
