Military Microwaves Supplement
The MILCOM management and sponsors made a wise decision to cancel the event this year as most of the east coast was pretty much closed down from hurricane Sandy. Everyone I know in New England down to the Mid-Atlantic found out over the weekend that their flights were canceled. It was a good move and addressed any safety concerns of people trying to get there. MILCOM even analyzed their attendee list and determined that approximately 40% of them would be affected by the storm so decided to cancel. I applaud them for taking this action and promoting it quickly to the attendees.
The thirty-first annual MILCOM Conference and Exposition, themed “Trusted Communications…Awareness to Action”, was to be held at the Gaylord Palms Convention Center in Orlando, Florida, October 29 through November 1. Co-sponsored by AFCEA International and the IEEE Communications Society, and hosted by Harris Corporation, MILCOM is the premier international conference for military communications. MILCOM gives industry the opportunity to promote communications technologies and services to commanders from all branches of the armed forces, Department of Defense, federal government, and the heads of multi-national forces from around the globe.
Even though the show was canceled, there was still a lot of company news and products that I received for the event so here is a summary of the show that did not happen from an RF/microwave perspective:
Agile Milcoms was going to demonstrate their new ISR-Direct™ platform that delivers FMV (Full Motion Video) and data directly to the Warfighter via handheld tablets and smartphones. This new platform incorporates key Agile Milcom components as well as Haivision’s Makito Air encoder and Kraken Transcoder. The ability to supply accurate and timely ISR (Intelligence, Surveillance & Reconnaissance) information is essential in today’s combat environment. ISR-Direct provides real-time video as provided from a multitude of the end-user sensors combined with map overlay and two-way data to the critical edge, allowing Warfighters to have up-to-date ISR information during their mission. I wanted to see this in action so maybe we can get a video or something later to see this demonstration.
