What's Inside Technical accuracy is the responsibility of the author(s). PLEASE reference this code when ordering from this issue 2014 07093 Mobility Solution Enables Real- Time Video Streaming for Police Boats on the Chesapeake Bay Submitted by RAD The Chesapeake Bay is a beautiful and invaluable resource to the Maryland- Delaware region and beyond. Among its many roles, the bay is host to numerous active seaports, a venue for recreational and commer- cial fishing pursuits, a destination for millions of annual visitors, a strategic gateway for maritime traffic seeking access to U.S. shores and home to the Calvert Cliffs Nuclear Power Plant. Maryland Natural Resource Police (MNRP) is the enforcement arm of the Department of Natural Resources (DNR), tasked with the solemn responsibility to provide for the safety and security of the bay itself and all that occurs within its waters. These responsibilities include, among others, homeland security operations, search and rescue teams, emergency medical services, education, and information and com- munications services - all on a round-the- clock basis. Can I Get It In Real Time? With a fleet of approximately 140 vessels to cover the Chesapeake Bay's sprawling 64,000 square miles, the MNRP relies heavily on technology to successfully perform its duties. The MNRP has employed craft-mounted video surveillance for many years, but, until recently, a significant limi- tation was that the video feed could only be stored locally and downloaded once a boat was docked. For optimal operational efficiency and safety , the MNRP needed a solution to enable real-time video streaming. The DNR searched for more than four years to find an acceptable solution. Their search spanned a slew of different vendors and a range of technologies, including Wi-Fi mesh, WiMax, LTE cellular and a number of proprietary point- to-multipoint wireless solutions. Still, none of these met the baseline requirements of deliver- ing up to 3 Mbps throughput up to 7 miles off shore while traveling at up to 40 knots/46 mph. Finally, acting on a recommendation[from a trusted wireless technology integrator, they iden- tified RAD's Airmux Mobility wireless solution as a viable candidate. Certainly, the Airmux Mobility solution's documented capability to support up to 100 Mbps throughput at speeds up to 107 knots/124 mph seemed promising. The next step was to put it to the test.

DAS Designs Gain in Popularity Submitted by Transtector Distributed antenna system (DAS) designs are taking hold worldwide as avenues for providing coverage in targeted locations. Utilizing a struc- ture similar to spokes off a hub in a wheel- with a cell site, or macrocell, as the hub and antennae as the spokes outward in areas of concentrated demand-DAS solutions typi- cally can be shared by multiple operators using localized power. While a DAS site may have less com- prehensive capabilities at each site than a typical small cell, the goals are the same: Deliver better coverage to meet ever-increasing demands for mobile data bandwidth with power as a crucial component. "Like a small cell application, we have the same concerns about keeping equipment online and keeping the power clean," said Matt Hepler, Account Manager for Transtector Systems. AC, DC, data (Gigabit Ethernet), and RF protection are integral technologies. A DAS location may have an industrial application nearby causing power interference, for example. Ensuring the quality of power is crucial to ongoing network integrity. "Obviously, the important goal is to keep the network online," Hepler said. "Protecting power and installing the best quality grounding are both critically important." Key product features to seek when choosing RF protection equipment include low voltage let-through, proven reliability and configuration options to fit the application.
