New Maxxcasting SFN Serves Boston Station
November 9, 2016
Solutions is calling attention to a deployment of its SFN-based MaxxCasting
system that it says is helping a Boston FM reduce signal interference and improve its coverage-to-contour ratio to reach more
potential listeners. It says the installation also strengthens building
penetration in downtown Boston.
formed in 2009 by Peter
Handy, Chris Devine, Rick Bonick and Bill Hieatt, believes
it has identified a big potential business opportunity. It thinks
that in the top 30 markets, 18% of the population is not covered within stations’
protected contours. So it makes systems that are intended to enhance coverage
areas (and thus reach more PPMs) using new techniques in single-frequency networks.
The manufacturer says big improvements
in coverage-to-contour ratio are an important benefit and
that its approach also eliminates common problems with legacy booster systems.
this project it worked with
Shively Labs, American Tower Corp. and its frequent business partner GatesAir.
The system at indy station WXRV(FM) 92.5 The River, which is licensed to
Andover, Mass., launched this month. GeoBroadcast Solutions credits the
installation with delivering stronger and broader signal coverage to 4.5
million people in the Boston metro. “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.”
system uses four low-power transmission sites in areas prone to interference or
weak signals. These nodes, on the same frequency as the main transmitter, are
in Lexington, Waltham and Natick on the outskirts of Boston, and on top of the
John Hancock building downtown (shown). Another site is planned in the Charlestown
The company says
its approach helps stations take all advantage of legally allowed coverage
through predictive modeling software to maximize a network topology; it
combines radio broadcast and mobile cellular technology to reduce or eliminate
interference between main transmitter and nodes. The nodes
use GatesAir IP networking to transport and synch program content across the
transmitters; nodes are synched to the main using GatesAir Intraplex

content from the studio to each node and the main transmitter. Shively created
custom antenna pattern designs to control node coverage, according to the announcement of the project.
up a listening test involving station General Manager Donald St. Sauveur and representatives
broadcasters. It quoted St. Sauveur saying the experience
of listening to the main transmitter as it transitions to the nodes is “seamless
and undetectable to the general audience.”
company has another offering called ZoneCasting that awaits FCC
approval and on which Radio World reported four years ago. It would provide
technology to geographically target radio advertisements.
