800 MHz Retuning Begins in Colorado.

Post by Brian »

One of these year it will happen? in San Diego County RCS system ;)
some nice reading too

----------------------------------------
Physical retuning in the 800 MHz rebanding process has begun in Colorado,
with one of the nation's largest public-safety systems starting the
technical and logistical challenge this week. Nearly 30,000 subscribers will
be returned as part of the Consolidated Communications Network of Colorado
(CCNC).

Colorado's statewide Digital Trunked Radio (DTR) system officials signed the
final documents with Sprint Nextel April 4 after six months of negotiations.
The carrier could pay up to $14 million to reband all the state's equipment.

The state has been divided into three regions, all of which began retuning
May 7 in conjunction with Motorola and three two-way radio repair shops. The
project will be used as a model for the rest of the country, said state
officials.

The state's goal is to get the majority of the work done by fall, when heavy
snow could hamper the efforts. "We need to get it done before the snow
flies," said Dennis Kalvels, electronic engineer and project manager of
rebanding for the state of Colorado.

The work will be complicated by several factors. The state is still building
out its network and will be adding new sites all summer; construction on a
new site will begin each week throughout the summer months, and the new
sites will also have to be rebanded, according to Mike Borrego, Colorado
electronic engineer. In addition, Sprint Nextel hasn't cleared some
frequencies yet, so negotiations will continue between CCNC and Sprint
Nextel to address those issues.

All subscribers on the DTR systems will be touched twice, officials said.
After the subscribers are touched the first time - scheduled to be completed
by the end of August - the state will reband all infrastructure,
bidirectional amplifiers, and international tactical channels (ITACs). Then
a second touch of subscribers will be followed by rebanding suitcase and
vehicle repeaters.

The radio repair shop in each region has a mobile trailer set up with all
equipment needed to do the work, said Terri Thornberry, Motorola's lead
project manager. The trailers will travel to each county in the state. On
the first two days of retuning, more than 100 radios were retuned each day.
