CHICAGO,�November�16, 2016���GeoBroadcast Solutions�(GBS)�has been granted a patent�for key�innovations in�itsMaxxCasting radio coverage optimization system.�The new United States patent, number�9232481, protects GBS� unique technology�and methods�that help radio broadcasters maximize their signal quality and coverage�with their protected contours�to�increase�advertising revenues and listener�retention.
�GeoBroadcast Solutions has patented a technology that will revolutionize the FM radio business,� said John Bridge,�owner of Chicago-based�Windy City Broadcasting.��As a key investor and a strong believer in this important and timely technology, MaxxCasting will help station owners improve their signal coverage and quality, enhancing their bottom lines while returning ad revenues to�the�industry at large.� �
While radio stations are permitted to broadcast signals throughout their legally-associated metropolitan�or�geographic�area, impediments including natural terrain and man-made obstacles often create gaps in coverage where transmissions from the main antenna cannot be effectively received.�In other cases, the�sheer�expansiveness of a station�s designated broadcast region, defined as a service contour,�may�prevent�signals�from the main transmitter from reaching potential listeners on the edges of the�permitted�area.�Additionally, the station�s transmitter may reside considerably outside the desired principal city, adversely affecting listenability and failing to decode on�Nielsen�Portable People Meter (PPM) units that measure potential audience exposure.
Combining�highly-accurate,�predictive modeling with�advanced�radio and cellular technologies�across�multiple synchronized transmitter nodes,�the�MaxxCasting system improves broadcasters� coverage-to-contour ratio�and�maximizessignal penetration within their markets.�Unlike conventional booster approaches,�which can exacerbate coverage�and quality�problems by creating interference with the main transmitter signal, MaxxCasting�s proprietary methods minimize or eliminate such interference.�The enhanced coverage�allows broadcasters to reach more�PPM�ratings measurement locations, increasing�ad�revenue potential�while�also�attracting new advertisers in previously under-served areas.
�Our research has shown that across the United States as a whole, close to 20% of the�population�in the top 30 markets�that FM broadcasters could�legally reach are not actually receiving such signals,� said Bill Hieatt, Chief Technology Officer, GeoBroadcast Solutions.��That�s a huge,�untapped�audience�for advertising�that�could�contribute�right to broadcasters�bottom line, but previous approaches have generally had limited success in solving the problems.�The grant of this patent demonstrates�and further validates�the unique and innovative nature of our MaxxCasting solution, while our successful commercial deployments prove that it delivers on its promises.�The patent also helps�protect our customers��investments�in MaxxCasting, ensuring that�the�innovations and�advantages we bring them�can�t simply be copied by�either�their competitors�or�ours.�
At the heart of the MaxxCasting system�are�GBS� proprietary�predictive modeling�formulas,�which consider�several�coverage-affecting environmental factors.�The�predicted�results, which have proven exceptionally accurate, enable the design, optimization and deployment of single-frequency networks (SFNs)���architectures�in�which�transmissions from two or more locations share the same frequency, enabling seamless transparency for listeners���that fill in coverage gaps while minimizing�interference and audible distortion.�
Multiple, synchronized MaxxCasting nodes are deployed in the desired coverage areas with lower antenna�radiation heights than the main�transmitter,�with the�node�signal level�decreasing rapidly as a function of distance.�This effectively reduces the geographic area where�a�node�s�signal is close�in power to the main transmission,�decreasing�interference.
As the time differential and RF signal power ratio between multiple signals reaching a receiver determine the amount of audio distortion heard by the listener, the MaxxCasting system topology optimizes both aspects.�GBS techniques can analyze simulcast performance using up to one meter terrain and�building resolutions, from an infinite number of arriving signals.�Leveraging�GBS� years of field experience and�the results of�controlled listening tests such as those performed in conjunction with�NPR Labs and Towson University, this analysis is then�used to predict the listener�experience and�refinethe MaxxCasting configuration accordingly.�
�Every dollar spent up front on modeling and prediction of MaxxCasting system performance can save our customers�hundreds of�dollars in the implementation and capital costs of trying to make everything perform well �in the field� with other approaches,� said Hieatt. �That�s yet another financial benefit of MaxxCasting ��we reduce the�deployment and operational costs of the SFN system, all while enabling increased revenues.�
All nodes are synchronized with the main transmitter using GatesAir Intraplex� SynchroCast3 technology, with program content transported through�Intraplex� IP Link 200 codecs.�Once a MaxxCasting deployment is�designed�and operational for�analog�FM broadcasting, the same system can�be�seamlessly�augmented to�support the less-stringent design requirements�of�digital HD Radio.�GatesAir is also the official transmitter supplier for MaxxCasting deployments.
In addition to its standalone benefits for�improving�radio coverage, MaxxCasting�s network topology and underlying technology are important components of GBS��patented�ZoneCasting solution�� a technology that Bridge says will �target commercial content to specific neighborhoods across broadcast markets with amazing accuracy.��Pending FCC approval, ZoneCasting will enable broadcasters to geographically target over-the-air radio advertising�by segmenting their main broadcast signal into defined zones, each�capable of�receiving discrete content as determined by the transmitting�node�on a minute-by-minute basis.�The same�powerful�SFN�simulcast optimization methodologies�used in MaxxCasting system�are used within each zone�of a ZoneCasting deployment.
GBS received a patent for innovations within its ZoneCasting solution in 2014, and additional patents are pending for bothMaxxCasting and ZoneCasting.�
