TORONTO, March 31 /CNW/ - Active Control Technology Inc. (TSX-V:ACT)
today announced a new purchase order for ActiveMine(TM), the premier wireless
voice communications and tracking system for mines. The system will be
installed at an underground coal mine in Illinois that plans rapid growth and
long-term operations.
The initial installation, scheduled for April 2009, will be the first
commercial ActiveMine deployment in Illinois.
ActiveMine wireless Wi-Fi network equipment will be installed in all
operating areas of the mine and in tunnels linking the network to the surface.
Initial requirements will include network equipment and handsets, with
tracking capability to be added later.
"Our new customer selected ActiveMine because of the productivity gains
it makes possible," said Steve Barrett, President and CEO, Active Control. "We
look forward to contributing to their success through ActiveMine's excellent
voice quality, high speed broadband capability, and plug-and-play
installation."
Deployment of the system is subject to MSHA approval of ActiveMine's
wireless Wi-Fi telephones. Certification of the phones - the final stage of
MSHA approvals for ActiveMine - is expected soon.
Active Control partner Fairmont Supply Company provided the initial
customer contact that led to the purchase order.

About ActiveMine

The ActiveMine communications, data and tracking system enables
monitoring of production, personnel and equipment in all types of surface and
underground mining environments, including coal and hard rock mines.
ActiveMine is positioned to bring to mining what the Internet brought to the
world. The system is designed to:

<<
- Provide the world's first standards-based Wi-Fi + IP network for the
underground mining industry with a 54Mb wireless backhaul.
- Provide full duplex, clear voice communications and tracking as
required by law in US underground coal mines.
- Provide ample bandwidth to move existing legacy applications onto a
single standards-based network, eliminating multiple proprietary
networks.
- Enable the deployment of an unprecedented array of new IP-based
applications in mines - applications that are not possible with
current proprietary and antiquated wired networks.
- Enable the deployment of any Wi-Fi device in mines, thereby driving
the availability of new devices, controlling costs, and freeing mine
operators from being locked into proprietary technology.
