Wi-Fi link distances up to fourteen miles with mobility
The network consists of both fixed and mobile nodes operating at both 5.8 GHz and 2.4 GHz using 802.11a, and -b. The fixed nodes are located on towers along the border and some are deployed with sectored antennas for long-distance connections. Backhaul node-to-node distances range up to 14.4 miles, although most are in the three- to four mile range. Some of the wireless mesh sites are so remote that there is no AC power supply, so solar arrays, wind power, and batteries power the equipment. Specialized support in the MeshDynamics wireless mesh nodes for long distance 802.11 connectivity allows even the longest links to operate at up to 54Mbps.
The mobile nodes are mounted in security vehicles and provide connectivity to agents' data terminals. The MeshDynamics mobile wireless mesh nodes include a scanning radio, which offers make-before-break connectivity in the moving vehicles. The scanning radio allows the vehicle to travel through the network at high speeds while maintaining uninterrupted connectivity for security applications.
Node mobility: a Third-Generation challenge solved
High speed node mobility is one of the key benefits of MeshDynamics' Dynamic Distributed Radio Intelligence technology. Combined with the company's industry-leading Third Generation support for high performance over many hops, the network provides a reliable framework for security personnel communications. "Over many hops, only Third-Generation architectures provide enough bandwidth with low jitter and delay at the distant end of the network," noted Francis daCosta, founder and CTO of MeshDynamics. "But most Third-Generation solutions depend on fixed link and channel configurations. The border network's high-speed mobility requirement mandates more channel management and topology intelligence in each node, which only MeshDynamics delivers."
All over the country, community leaders are looking to boost economic development through various initiatives. One key element in many of those initiatives is the use of information technology. When local governments build IT infrastructure, create e-government applications, assist high-tech startups or otherwise focus on technology, they create conditions that draw businesses to their communities and help retain skilled workers. This paper discusses and provides examples of these various ways local government can use technology to ultimately make a community more attractive to businesses, visitors and residents.
