Thanks Sajan.
Now let's look at their brief, and the reality. This is a pretty long
mail, the first part being a discussion of the SACFA guidelines, the
middle part specific suggestions for inclusion in a recommendation
paper for TRAI, and the last being a recompiled list of
recommendations incorporating all these. I have put several line
spaces to separate these three parts, to make it easier to scroll
down. When commenting please only copy the relevant portion and not
the whole mail.
Both Arun and I, among others, have advocated over the years that it
should not be the role of the government to adjudicate between
different technologies, but only with their application.
Unfortunately the trend to omniscience continues, with TRAI mandated
to rule on carriage instead of content, and in this case,
specifically for FM, rather than public service. In fact, on this
list and at the various Open Houses we all have more or less accepted
that the broadcast code used by AIR is good enough to continue for
all. However, the real threat to use of the Code is the technical
obfuscation and cumbersome procedures adopted for no good purpose.
Although we do not believe that this process is the most effective
way to go about things, we do not refuse to participate, rather we
hope that our inputs will add value to the extent possible, in
generation of good policy.

Exactly. They already have some kind of guideline that was clearly
intended to ease their work, but which seems to have been, in the
typical bureaucratic way, been expanded to include everything but the
kitchen sink - and even that, if it is over 3 meters high. Easier
work ends up taking two years and more to clear a simple matter like
an application to broadcast low power FM. There must be a better way.

a) Aviation hazards are covered, please note, in a manner that is
surely inadequate by today's aviation norms. I would like to know
what kind of commercial jets normally flies off short runways? 3 km
is the runway length alone, for most large bodied commercial jet
aircraft, the type used in India, and for practically all land-based
fighter aircraft. Surely they have the right to expect
interference-free communications for more than that length after
take-off? My point being that there is a case to believe that the
departments are not concerned with effective governance, but only in
status quo and maintenance of power.
If the techies within SACFA (would this be the civil aviation
ministry experts?) know how to avoid interference for low flying
aircraft, and conversely, how to use low power radio signals to mess
up communications for low flying aircraft, especially in landing and
take-off, this ought to be public knowledge, to avoid mishap in the
future. Only terrorists and governments hoard information.
b) Existing/planned networks! And who on earth do they think is doing
the planning? This sounds like a perfect Catch-22. The same reaction
hit me when I looked at the next point, which refers to proposed
networks, without any hint of when such networks are expected to be
implemented.
Still, this is in a sense nitpicking, and if one could be lucky
enough to find non-venal or dedicated officers filling the steering
seats in SACFA, the guidelines should not, theoretically, pose a
hindrance to speedy clearance of new applications. Since this is not
a given, with the current level of dedication obvious among
government officers (evidenced by the extraordinary rapidity with
which last year's applications have been disposed), there is no harm
in asking TRAI to make things a bit clearer, either by sticking to my
original suggestion, or by appointing a special low-power wireless
frequency clearance committee that overrides SACFA's brief for the
specified FM band.
I have discussed these two scenarios once again below, plus added a
suggestion for conflict resolution on EMI/EMC interference.

If you have seen photos of cities like Toronto and Stuttgart, one
very prominent feature of the skyline is the TV tower, a commercial
building with a large mast on top. This allows the offices, studios
and antennae of the enterprise to be conveniently situated in one
building. Unfortunately, we don't have this luxury in any of our
cities, and negotiating a deal with an existing building owner could
be as inconvenient or just plain bad business sense (example: imagine
a special arrangement with a frequency clearance officer for say, one
year's operations only, next year come back and deal again).

Amazing. Can anyone imagine why SACFA was given this life-and-death
control in the first place? 50 watts! But look at (c) below, and it
is clear that section b) is *not intended* to cover FM broadcasting
stations. Whether or not the 50 watt categorisation is justified, it
does not affect those interested in low power FM broadcasting. It
does however, impact on the liberalisation of AM (medium wave)
broadcasting.
>(ii) All VHF stations in the frequency range 174-230 MHz with

>(c) Broadcasting stations in the frequency band 30-230 MHz with
>power output more than 100 watts.
So it is only FM broadcasting stations with power above 100 watts
that get covered by the "full siting category" nutcracker. I do not
understand why low power AM is getting stepmotherly treatment. While
the medium does not guarantee noise-free audio to the receiver, it
can work better for hilly areas, which is many important parts of the
country. I am puzzled by the lack of interest in speedy disposal of
applications for medium wave broadcasting as well as FM. I think
discussions on this list have not paid sufficient attention to
establishing community-focused public service radio in areas where FM
is not the most suitable choice.

I hadn't spotted the detailed SACFA guidelines before putting out
this suggestion, and now feel that it wasn't specific enough to deal
with the threat of stiflement, with which we are already familiar.
I therefore suggest that TRAI adopt a clear policy for both low power
medium wave and FM broadcasting, opening up - liberalising licensing
- of which will create an environment for the production of better
content than we currently experience, given the expensive luxury of
stations that constitute the commercial FM bands.
This policy may encompass Arun's suggestions just as posted to this
list, but with the following modifications (numbering as per Arun's
original - I have, right at the very end, compiled a complete list
for ease of reference):
5. Antenna height: Use of antennae for medium wave or FM transmitters
under 100 watts will be allowed at heights up to 3 meters from the
topmost point of existing buildings and natural prominences, subject
to the site being at least 3 km from the runway direction within 45
degrees to either side, for both ends of the runway. The construction
of the mast should be in conformance with local building laws,
wherever applicable.
Explanation: Aircraft communications that can be affected by
terrestrial broadcasting are only relevant in line with the runway.
An aircraft that is approaching a runway over 45 degrees from its
direction is obviously not intending to land, and is also unlikely to
be low enough that interference with communications could even happen
in the first place.
Note: I don't know who must have dreamed up the 3 meter restriction,
but at least one thing is reasonably clear: such a short mast is not
likely to be a hazard to persons in the vicinity, and even a very
poorly trained mason or ironworker ought to be able to erect such a
tower competently and inexpensively.
In rural areas, expect incompetency: the lack of training and skills
is closely linked to the lack of education and opportunity. This is
in fact why the need for effective communication is urgently felt.
Although optimal reach is as important in rural areas as in urban,
and in fact even more so, given the relative paucity of financial
resources for development, a rule that limits access to simplified
antenna placement to buildings only is discriminatory: tall trees,
rocks and hills must also be allowed. Usage restrictions of all kinds
need to be eased or lifted entirely. Antenna masts should not be
defined as 'constructions', or else forest dwellers will be denied
use of their own natural resources.
6. Permissible reach/coverage: As determined by the applicant, taking
care not to interfere with broadcasting/communications from existing
wireless networks. In case a new wireless network is already under
implementation, care should be taken by the newer station to avoid
interference with the older applicant. Such a condition will only
apply for eighteen months after start of construction.
Explanation: Low power broadcasting has been determined to be
irrelevant to high power broadcast signalling quality at the
recipient side. The reference is the Mitre study, carried out
independently but taken on board by the US FCC, in determining
conditions for future licensing of low power wireless broadcasting in
the USA.
This means that if the new station under implementation is a high
power station, then the fresh applicant will have to take care not to
interfere when the station is ready. However, it is not a blanket
veto handed over to potentially dog-in-the-manger station owners, it
will be time limited to eighteen months from the start of
construction of the station. If they delay construction or are
otherwise delayed in beginning operations, they should not forever
enjoy early bird benefits.
14. Conflicts: The District Collector should carry the role of
ombudsman in local interference conflicts, in case any such arise. If
the conflict cannot be resolved through technical adjustment of
existing installations, the Collector may be empowered to expedite
the assistance of technical experts from the relevant ministry to
recommend a solution.
Explanation: With SACFA and WPC out of the picture, it is important
to replace them with a more effective local governmental mechanism.
Complete list of recommendations:
1. License fee
none
2. Spectrum Usage Fee
none
3. Bank Guarantee
none
4. Transmitter power
100W, for more, you have to apply specially.
5. Antenna height
Use of antennae for medium wave or FM transmitters under 100 watts
will be allowed at heights up to 3 meters from the topmost point of
existing buildings and natural prominences, subject to the site being
at least 3 km from the runway direction within 45 degrees to either
side, for both ends of the runway. The construction of the mast
should be in conformance with local building laws, wherever
applicable.
6. Permissible coverage area of CR station
To be determined by the applicant, taking care not to interfere with
broadcasting/communications from existing wireless networks. In case
a new wireless network is already under implementation, care should
be taken by the newer station to avoid interference with the older
applicant. Such a condition will only apply for eighteen months after
start of construction.
7. Quantum of advertisements per hour of programming
Ten minutes maximum
8. Permissible limit of advertisement revenue per CR station
Not more than 25% of total revenue
9. Number of licenses per CR licensee
One per coverage area, more subject to availability of spectrum.
Spectrum availability to be publicised, against a review of the
technical specifications for FM broadcasting prevalent in major
wireless user countries.
10. Frequencies to be allotted for CR /Maximum number of CR
stations per location
Three reserved frequencies; if there are more applicants in a given
region this number may be expanded, subject to availability of
spectrum. The District Collector will be the Competent Authority for
allocation of reserved frequencies.
11. Period of license / period of extension
Same as commercial
12. Time limit for clearances
3 months
13. Period for preserving audio logs
Indefinite. Archiving done at central facility created for this
purpose. Use CDs, and specify compliance with a suitably open format
(it is inefficient to define the actual format to be used by each
station, as long as data is exchange-compliant).
14. Conflicts
The District Collector should carry the role of ombudsman in local
EMI/EMC interference conflicts, in case any such arise. If the
conflict cannot be resolved through technical adjustment of existing
installations, the Collector may be empowered to expedite the
assistance of technical experts from the relevant ministry to
recommend a solution.
