Wireless broadband 101

A look at a few players in wireless broadband services for city wifi and municipal surveillance


Firetide 's HotPort High Performance Mesh Network provides maximum versatility to conform to any environment. The MeshBridge feature allows interconnection of multiple networks, even those operating on different frequencies and applications.

The MultiMesh application can cost effectively accommodate both singleand multiple-administrator management of the networks. With HotZones and HotRegions mesh technology, agencies can expect consistent connection of multiple HotSpots for Internet access indoors and outdoors, availability of both restricted-access private networks and open-access public networks, real-time video monitoring and surveillance for enhanced public safety and a highly portable network that can easily be moved to another location.

What Ksenia Coffman, marketing manager for Firetide, hears most often from customers is the flexibility and ease of deployment offered by mesh wireless. Firetide also delivers the highest bandwidth for evidence-grade video, reducing the number of radios needed by almost half. Firetide utilizes systems integrators to present a complete solution to each agency, from deployment of new projects to integration into existing systems.

In early 2007, the Dallas Police Department implemented a wireless video surveillance system in an effort to reduce crime in the Central Business District. Dallas-based BearCom was the overall manager of the project and brought in Firetide, Sony, and several other wireless companies as strategic partners. Sony's Model 550 cameras with pan-tilt-zoom capability were installed at major intersections that cover more than 30 percent of the total downtown area. These cameras connect to Firetide wireless mesh nodes that form a resilient mesh network, resulting in guaranteed camera connectivity.

Qualcomm

In 1989, Qualcomm introduced Code Division Multiple Access (CDMA), an unparalleled technology for wireless and data products. Initially developed for commercial use, CDMA allowed more efficient voice and data transmissions between mobile devices and cell sites than comparable technologies. Qualcomm's latest version is CDMA2000, which exceeds third generation standards for improved peak rate download and upload speeds.

Eventually expanding its technology to the public sector, Qualcomm launched an initiative in 2006 to assist in recovering abducted children. Working with the National Center for Missing & Exploited Children and the AMBER Alert Highway Network, Qualcomm's satellite-based mobile communications system collaborates with professional truck drivers nationwide to locate missing children.
