Case Studies
CN Tower, Toronto(supplied by Mobile Business Communications Ltd.)
Since 1976, Toronto's CN Tower – the tallest freestanding
structure in North America – has played a key role in the city’s
telecommunications infrastructure, and it also offers visitors a
superb view from its two observation decks. A building of this
unusual nature poses some special challenges for the people
who work there – and that goes for their radio system too.
According to Kerry Adams, President of MBC – the Toronto
dealer who installed the CN Tower system – ensuring that a
solid signal propagates throughout the facility was an
important factor in the selection of NEXEDGETM– with its
6.25 kHz capability– to replace the previous analog LTR®
trunked system. The new digital trunked system also
brought them increased capacity, allowing for multiple talk
groups– not previously possible with the LTR®system – so
employees in different departments can all be talking
simultaneously yet independently, enjoying excellent voice
quality with greater protection from eavesdropping. And as
the new system uses the same 450 MHz band, migration was
smooth. NEXEDGETM has proved to be an ideal solution for
this famous Canadian landmark.
A Beep, Chicago
A Beep was started in 1996 as a paging service, but now
the company is one of the largest SMR operators in
Chicago. To compete effectively with cellular systems, they
selected NEXEDGETM for their new Diga-Talk service. They
cite 5 key reasons for their choice: IP networking, 6.25 kHz
modulation, sound quality, system layout, and cost. Ease
of management, and proven Kenwood quality and
support only made the decision easier.With 9 sites linked
by IP network and another 3 scheduled, A Beep can offer
wide area seamless roaming over the entire Chicago
metropolitan area, which has a population of 9 million.
Increased coverage brings portable radios more
availability in the field, just like mobile radios. Also,
Diga-Talk can satisfy the needs of smaller companies,
not just fleet customers. The opportunities for
messaging and GPS are also attracting new clients,
such as limousine services, cab companies, and
landscapers.
