Digital
Wireless Corporation is a pioneer and leader in the field
of digital dispatch voice and data radio with specific emphasis
in the utility industry providing high security voice, data,
GPS tracking, SCADA and utility meter control all on one cohesive
IP VHF/UHF system.
Internet
Dispatch Radio
The evolution orchestrated by Digital Wireless Corporation
takes dispatch radio to a level long dreamed of by dispatch
radio system users, but never achieved by radio manufacturers
focused on "high-end" public safety systems. In
contrast, Digital Wireless Corporation's i2way® dispatch
radio system provides high performance and features that equal
or exceed high-cost systems while retaining the ease of use
and ease of maintenance needed by the budget conscious system
user/operator.
The
"Basic" system is fully enabled to provide the advanced
features and capabilities required by the system operator.
All features and capabilities are standard and incorporated
and enabled in the basic product design. These features and
capabilities include:
6.25
kHz Channels
DWC's FCC-approved 6.25 kHz format provides much the
same range as analog FM but with noise-free, secure digital
quality in Ultra Narrow radio channels. Ultra Narrow 6.25
kHz operation provides users with hundreds of new, potentially
exclusive radio channels at every location in the country.
DWC's exceptional quality digital audio makes the long anticipated
but formerly useless 6.25 kHz channels, not only practical,
but also desirable, for their range, availability and exclusivity.
i2way Ultra Narrow uses the radio spectrum more efficiently
than ever before and gives users unique feature advantages
over existing circuit-switched technologies, such as GSM,
PCS, cellular, and legacy dispatch radio. These ultra-narrowband
radios make obtaining FCC licenses easy.
Networking
i2way makes it possible to operate extremely wide area
networks without the heavy costs of infrastructure equipment
or construction.
i2way uses the Internet (or a private MPLS Intranet) for inter-site
networking. With the aid of the Internet, people are communicating
in ways never before thought possible. Digital Wireless Corporation
invented DV/IP™ dispatch radio VOIP in 1996, the basis for
the i2way® Network, a high speed trunked radio network
with secure, digital audio, integrated unit tracking and integrated
data transmission to help geographically diverse organizations
centralize operations and operate more efficiently. The basic
call commodity is push-to-talk voice dispatch. i2way is sophisticated
and secure, yet it was designed to emulate "plain old
fashioned" two-way radio users are familiar with. Voice
is sent digitally at 2400 bits per second as part of 10,000
bps packets. It sounds like analog audio - but without any
noise.
i2way's
In-Band linking capability allows sites to mesh network to
a nearby site using their UHF or VHF channels should backhaul
fail. DWC's completely digital i2way product family operates
in the 380-520 MHz bands, in 12.5 kHz and 6.25 kHz spaced
digital channels.s.
Encryption
Because i2way uses 256-bit key AES end-to-end encryption,
it is as secure over the Internet as it is over the air. Because
i2way uses the proprietary DV/IP protocol, which is protected,
scanner manufacturers and professional interceptors have not
compromised communications security as they have "open"
standards. i2way 256 bit encryption not only secures voice
and tracking data, it also protects utility meters and DNP-3
SCADA data from interception.
Tracking
i2way portable and mobile radios include built-in GPS receivers
as standard. DWC's fixed base stations include GPS receivers,
too, primarily to transmit GPS ephemeris data to portables
and mobiles to speed up satellite acquisition in ultra critical
radio systems. The company's Desktop Dispatch Suite provides
real-time map display of the location of mobile and portable
units. The i2way Digital Logging Recorder archives voice and
data transmissions at the same time storing the geographic
location of the transmitting radios.
Data
Communications
An i2way radio is digital consequently it has the advantage
of not requiring a modem to convert digital signals to analog
to for wireless transmission. The radios transmit digital
location information at every PTT key and have the capability
to send digital status messages to and from the dispatcher
and mobiles. Interface to a digital terminal is as easy as
plugging in an USB connector or Bluetooth link.
Trans
Oceanic Networking
One typical i2way Network user routinely talks mobile to mobile
from vehicles in Los Angeles, California, to vehicles in Sydney,
NSW, Australia. Delay (and quality) is little different than
if the units were mere blocks apart. i2way operates large
networks on both continents. Should one of the American portable
radios travel to Australia, the instant it is turned on in
Australia the radio automatically seeks out local i2way cells
and logs on to its radio fleet in California,without any operator
intervention or programming. i2way is already in commercial
and military use around the world.
