Introduction ISDB-T, TDT DVB, DVB-T, ATSC-M/H Standards Are in Place in LATAM ALL of These Standards Support Broadcast to Mobile Receivers This is THE Time for Broadcasters to Move Ahead of Competitive Delivery Methods (Satellite, Cable) While Keeping The System Flexible Enough for Future Enhancements/Expansion What Does the Broadcaster Need to do to Take Advantage of Standards and Technology to Gain An Advantage Over Competitive Delivery Methods and Competitor Stations? Polarization Diversity…… © Radio Frequency Systems 2011 All rights reserved
Polarization DiversityPolarization Diversity-Adding a Vertical Component to the Radiated Signal to Increase Receive Probability. The Amount of Vertical Component Is Typically From 20% Vertical (Elliptical Polarization) to a Full 50% Vertical (Circular Polarization) Why Is This Important? In a Mobile Receive Environment, the Receiver Acts As a Linear Dipole Orientation Is Constantly Changing Critical in Non Line-of-sight and Fringe Areas Traditional Broadcast Is Horizontal Polarization Only (94% Pre-transition) The Mobile Environment Is Broadcasters “Sweet-spot” to Regain Viewers Over Satellite and Cable Delivery Systems Is There a “Magic Number” for the Polarization Ratio Which All Broadcasters Should Consider for Delivery to Mobile Devices There is no magic number however studies Show That ANY Incremental Vertical Polarization Is Beneficial However Every Station Will Have Different Economics and Timing to Support Mobile © Radio Frequency Systems 2011 All rights reserved
Polarization Diversity ContinuedStudies Have Shown That by Adding a Vertical Component to the Radiated Signal Increases the Margin at the Receiver by 2 to 11db How Can This Be Achieved? Elliptical Polarization or Circular Polarization From a Common Array Is There a Way to Upgrade The Antenna System Today While Allowing for Future Polarization Ratio Changes As the Business Model Focus Transitions to Mobile? Absolutely-Using Variable Polarization Technology (VPT)! © Radio Frequency Systems 2011 All rights reserved
Variable Polarization Technology (VPT)VPT Allows for Each Channel in a Master Array to be Operating with a Polarization Ratio Independent of the Ratios of Other Channels Operating in the Same Array Stations can Operate Horizontal Polarization, Elliptical Polarization and/or Circular Polarization Simultaneously in the Same Array Why is This Important? Today’s Polarization Ratio is Typically 100% Horizontal (Just Upgraded DTV Transmitter) and Additional Transmitter Upgrades in Coming Years Determining What the Right Polarization Ratio Can be Dependant on Channel of Operation, ERP, Terrain, Competition, Transmitter Limitations…Not the Same For Every Broadcaster The Polarization Ratio May Change as the Business Model Matures and Supports Mobile Reception System is Future-Proof! Allows for Future Polarization Ratio Changes Without Antenna System Changes! Allow Stations to Leap Frog the Competition on Their Time Frame © Radio Frequency Systems 2011 All rights reserved
