I suspect that the "Intranet" described below will be built on Linux-based IP
|
|
routers, possibly a simple implementation that can be booted from floppy
|
|
or Flash Card.
|
|
<P>
|
|
It's going to be very, very interesting.

TAPR was founded in 1982 as a membership supported non-profit amateur radio
|
|
research and development organization with specific interests in the areas
|
|
of packet and digital communications. In the tradition of TAPR, the Board
|
|
of Directors at their Fall 1995 meeting voted that the organization would
|
|
begin to actively pursue the research and development of amateur radio
|
|
spread spectrum digital communications. At the Spring 1996 board of
|
|
directors meeting, the following statement of purpose was passed:
|
|
<blockquote>
|
|
"TAPR believes that the technical facts support our conviction that
|
|
conventional and spread spectrum systems can coexist without detriment to
|
|
conventional systems on all frequencies from MF to EHF. To this end, TAPR
|
|
will begin to research spread spectrum systems that will develop technology
|
|
for future deployment."
|
|
</blockquote>
|
|
As stated above, the TAPR board feels strongly about TAPR's focus on spread
|
|
spectrum technology and especially how it relates to the potential
|
|
coexistence on frequencies that will have increased number of users
|
|
occupying them. The amateur radio bands, like other spectrum will become
|
|
more heavily utilized in the future. It is in the interest of amateur radio
|
|
to develop systems that are interference-resistant while not interfering
|
|
with other primary or secondary users on those frequencies.
|
|
<P>
|
|
TAPR understands the concerns many have with the new technology, and
|
|
believes that efforts in both education and research is necessary in order
|
|
to allay the fears about interference and to demonstrate the benefits of the
|
|
technology.
|
|
<P>
|
|
TAPR believes that todays' communications technology is moving toward all
|
|
digital transmitters and receivers. These advances in technology, combined
|
|
with the swift evolution of cell based transmission and switching protocols,
|
|
are opening up a new set of possibilities for unique new services utilizing
|
|
intelligent networks. These will contain smart transmitters, receivers, and
|
|
switches. Today's Internet is perhaps the best example of a self-regulating
|
|
structure that embodies these new technological approaches to communications
|
|
in the networking domain. However, to date, many of these innovations have
|
|
not moved into the wireless networking arena. TAPR will work on moving
|
|
these innovations into the amateur radio community.
|
|
<P>
|
|
TAPR feels that the VHF/UHF/SHF radio networks of the future will involve a
|
|
mixture of links and switches of different ownership, which terminate at the
|
|
end-user via relatively short-distance links. What will then be required is
|
|
a built-in, distributed, self-governing set of protocols to cause the
|
|
network's behavior to make more efficient use of a limited, common shared
|
|
resource, the radio spectrum. Creating such a self-regulating structure for
|
|
the optimal sharing of spectrum will require much effort.
|
|
<P>
|
|
|
|
One of the major problems which stands in the way of these new approaches
|
|
today is the current FCC regulatory environment and the manner in which
|
|
spectrum is managed and allocated under its rules.
|
|
<P>
|
|
Historically, the current regulatory approach to radio has been based upon
|
|
the technology that was in use at the time that the Communications Act of
|
|
1934 was framed, basically what we would call today, 'dumb' transmitters
|
|
speaking to 'dumb' receivers. The technology of that time required reserved
|
|
bandwidths to be set aside for each licensed service so that spectrum would
|
|
be available when needed. Given this regulatory approach, many new
|
|
applications cannot be accommodated since there is no available unallocated
|
|
spectrum to 'park' new services. However, given the new set of tools
|
|
available to the entrepreneur with the advent of digital technology, what
|
|
once were 'dumb' transmitters and receivers can now be smart devices which
|
|
are capable of exercising greater judgment in the effective use and sharing
|
|
of spectrum. The more flexible the tools that we incorporate in these
|
|
devices, the greater the number of uses that can be accommodated in a fixed,
|
|
shared spectrum.
|
|
<P>
|
|
|
|
Therefore, TAPR will focus its spread spectrum effort in the following
|
|
areas:
|
|
<ul>
|
|
<li>TAPR will work to promote rules and technologies to make the most efficient
|
|
use of the spectrum through power control, forward error correction, and
|
|
other means to minimize interference among spread spectrum users and
|
|
existing communications systems.
|
|
|
|
<li>TAPR will work on issues and efforts with other national organizations to
|
|
change the regulatory environment and rules in order to promote the
|
|
experimentation, development, and later deployment of spread spectrum
|
|
technology.
|
|
|
|
<li>TAPR will work to develop information on the topic to help educate members
|
|
and the amateur community as a whole about spread spectrum technology, and
|
|
to disseminate this information via printed publications, the World Wide
|
|
Web, presentations at conferences and meetings, and other means.
|
|
|
|
<li>TAPR will work to foster experimentation, development, and design of spread
|
|
spectrum systems, and to facilitate the exchange of information between the
|
|
researchers and other interested parties.
|
|
|
|
<li>TAPR will work to develop a national intra-network to foster the deployment
|
|
of future high-speed spread spectrum systems into regional and local
|
|
communities, including the development of suitable protocols and guidelines
|
|
for deployment of these systems.
|
|
|
|
<li>TAPR will work with commercial companies who manufacture spread spectrum
|
|
devices which operate in spectrum shared by the amateur radio service (ARS),
|
|
in order to make them more aware of the nature of ARS operations on those
|
|
bands with the goal to work towards the deployment of devices which will
|
|
minimize interference between all spectrum sharing partners.
|
|
|
|
<li>TAPR will work with commercial companies who manufacture spread spectrum
|
|
devices in order to identify equipments that can be either used or modified
|
|
for use for Part 97 operation.
|
|
</ul>
|
|

Adopted by the TAPR Board on September 20th, 1996

at Seatac, Washington Board Meeting.
