CHICAGO,�November�9, 2016���GeoBroadcast�Solutions�announces the first of several�new�MaxxCasting�deployments designed to significantly improve market-wide signal penetration. The first of these systems, serving �Boston�s Independent Radio� station�WXRV(FM), launched earlier this month, and is delivering stronger and broader signal coverage to the approximately 4.5 million living in the metro area. This includes the�nearly 1.5�million�population of�adjacent Middlesex County, where interference�and weak signal�is�most�common due to�rolling hills�and other conditions that�deteriorate�signal performance.
Patented�MaxxCasting�systems�use GBS� unique�predictive�modeling software to�maximize network topology, enabling broadcasters�to increase�coverage and revenue potential�by�reaching more�Portable People Meters (PPMs)�and�attracting new advertisers.�MaxxCasting�combines�radio broadcast and mobile cellular technology�to�reduce�or eliminate�interference between main transmitter and�MaxxCasting�nodes.�
In the case of WXRV, the single-frequency network (SFN) architecture includes four low-power�transmission sites�strategically positioned in areas of the market prone to interference and/or weak signal coverage. These �nodes,��which are on the same frequency as the main transmitter,�are located in Lexington, Waltham, and Natick on the outskirts of Boston,and�on top of the John Hancock building in downtown Boston. A�fifth site�will soon�be added in the Charlestown neighborhood within Boston city limits.
Each node incorporates intelligent IP networking technology from�GatesAir�to transport and synchronize live program content across all transmitters,�which�ultimately contributes�to a seamless transition from node to node as mobile audiences move through the market.�Additionally, the�MaxxCasting�deployment strengthens building penetration in congested areas of the market, including downtown Boston.
WXRV General Manager Donald St.�Sauveur, who recently joined representatives from GBS,�GatesAir, American Tower Corp.�and regional broadcasters on a�successful�listening test in�the region, shared�that transitions between nodes were�noticeable only when looking at his car radio�s�RDS display. That display�temporarily indicated�individual node reception. It�ultimately will show�the same�artist/title information as the main station. �
�The experience of listening to the main transmitter as it transitions�to the various nodes is seamless and undetectable to the general audience,� said St.�Sauveur. �WXRV�s signal has improved substantially in areas that had been previously impaired for a variety of reasons. For example, the station�s signal�downtown and�south of Boston�coming off the Hancock Tower sounds robust, without interference and static. The benefits for greater coverage, larger audience share and future business opportunities with advertisers are obvious.� �
In addition to vastly improving coverage-to-contour�ratio,�MaxxCasting�systems eliminate�self-interference and signal degradation problems common with legacy booster systems�a problem that WXRV also experienced with a previous booster installation. To�outperform legacy systems, GBS uses�highly accurate modeling software�and�proprietary formulas�to measure a variety of environmental factors that affect coverage, including:
- Height above average terrain of each node
- Distance between each node, and the time differentials between each transmitter output
- Power ratio between each node
- Antenna patterns and interference areas
These�calculations�are�used to predict coverage improvements,�and�customize settings that at once improve market penetration and�eliminate interference between the nodes. All nodes are synchronized with the main transmitter using�GatesAir�Intraplex��SynchroCast3 technology. The�SynchroCast��technology is incorporated within�Intraplex��IP Link 200 codecs, which�transmit�the program content�from the studio�to�each node�and the main transmitter site.�Unique antenna pattern designs by Shively Labs�are key to controlling the extent of�each node�s�coverage,�and�mitigation of�self-interference.
�The coverage-to-contour�ratio is the key ingredient�to our success,� said Hal Kneller, VP Business Development,�GeoBroadcast�Solutions. �If a station is only covering 700,000 people inside a contour with one million potential listeners, they are not maximizing the legal coverage they are afforded by�the FCC.��The ultimate goal is to reach more listeners,�help them light�up more�PPMs to enhance ratings,�and attract new advertisers.�
It is estimated�that on average in the top 30 markets,�18%�of the population is not covered�within the stations� protected contours.�This creates a huge opportunity�for�MaxxCasting�to help improve a station�s bottom line. With tens of thousands of sites available through American Tower Corp, a�MaxxCasting�vendor�and�by�diplexing�multiple stations�at�a site�tremendous flexibility and efficiency of implementation is assured.
�It�was very reassuring to see�the�real world�node coverage and transition zone�performance�almost perfectly duplicate the GBS predictions,� said Jim Stenberg, RF engineer, American Tower Corp. �The seamless transitions from one nodes coverage,�back to the main signal and then�to another�node�were proof that they really can expand coverage without degrading the primary signal in any way.� It is now a new world for�expanding�FM�station coverage within their contours.� �
GeoBroadcast�Solutions, LLC (GBS) offers proprietary products and solutions to enhance radio station coverage areas to maximize both coverage and revenue as well as the ability to zone audio (pending FCC approval) and RBDS/RDS.��With several additional patents pending, new techniques for Single Frequency Networks have been developed to improve coverage.��GeoBroadcast�Solutions' charter is to innovate and bring to market technologies that help radio broadcasters maximize their signal and grow revenues.�MaxxCasting�will expand the coverage area of a FM signal.�ZoneCasting, pending FCC approval, will provide technology to geographically target radio advertisements. These emerging technologies give broadcasters tools to compete in�the face of innovations internet and cellular message distribution.�GBS partners with:GatesAir�for transmission and IP distribution equipment,�Shively�for antennas and�combiners,�and American Tower Corp for site infrastructure.
