Key Points
JRC welcomes the opportunity to comment on this consultation.
This is not an area of vital importance to JRC and its member companies,
but
we offer our comments in the hope that they may be of assistance to the
regulatory
authorities in discharging their duties.
Answers to specific questions posed in the consultation
VHF Band III
| Q1. Should available spectrum in LMS sub-band II and/or III
be used to ease
capacity restrictions in other PAMR/PMR bands? |
Yes, in so much as use of these sub-bands will not be adversely
affected by
increased restrictions on their use imposed under section 7.2.2. |
| Q2. Is there an anticipated market for digital PMR in Band
III?
| Users like to see multi-vendor support for expensive new
technology.
Manufacturers like to see a large market before committing investment, on a
regional basis or ideally globally. It is not clear at present whether a
sufficiently large market exists for suppliers to want to make products
available. |
| Q3. Do PAMR operators foresee an increase in demand for
spectrum in Band III
to
accommodate a growing customer base? |
Not applicable to JRC. |
| Q4. Is there anticipated demand for Band III spectrum by
the bus and coach
or
rail industries? |
Not applicable to JRC. |
| Q5. Is there anticipated demand for more VHF spectrum for
Terrestrial
Digital
Audio Broadcasting (T-DAB)? On what timescale is this needed, and, in general
terms, what should the development priorities be? |
By its nature, demand for broadcasting spectrum is always
likely to exceed
supply unless government imposes artificial constraints to the demand side (eg
onerous ownership or programming constraints). |
| Q6. Is there anticipated demand for VHF spectrum for
mobile, portable and
fixed
data/multimedia services? |
New multi-media services need a global market, and it is
unlikely that VHF
spectrum will be made available in sufficient countries to make this attractive.
In addition, VHF spectrum has a limited capacity for carrying multi-media
services, which makes it an unattractive option. |
| Q7. Is there anticipated demand for more VHF spectrum for
programme-making
purposes? |
Not applicable to JRC. |
1.5 GHz Band
| Q8. What is the demand for the 1.5 GHz Band spectrum for
T-DAB digital radio
multiplexes licensed under the Broadcasting Act, and what factors should
influence the size of multiplexes? |
Not applicable to JRC. |
| Q9. Is there anticipated demand for the 1.5 GHz Band
spectrum for mobile,
portable and fixed data/multimedia/broadband services? |
Yes, this band could possibly be used for these
services. |
| Q10. What is the demand for the 1.5 GHz Band spectrum for
the delivery of
digital radio, data etc services via satellite? |
Not really applicable to JRC. The existing satellite bands
seem to have
enough
capacity for data services to meet our requirements. |
| Q11. Is there demand for the 1.5GHz Band spectrum for any
other services on
a
secondary basis? |
JRC understands that in some countries, bands exist in this
part of the
spectrum
for deregulated telemetry and telecontrol applications (believed to be the case
in the USA), but we have no particular knowledge of whether a demand for such a
service exists in the UK, and how it might interact with a licensed
service. |
Detailed Comments
If as stated in section 7.2, there is to be a regional planning conference
affecting potential future use of this spectrum for broadcasting, it seems
unwise for the UK to take any action which might be adversely affected by any
decisions from this Conference. On a number of previous occasions, utilities
have found themselves disadvantaged by new restrictions imposed following World
or Regional Radio Conferences, especially where decisions have been taken about
future broadcasting use. If OFCOM were to facilitate use of this spectrum
before this Regional Conference for a service which were then adversely affected
by proposals at the Conference, OFCOM would come under pressure to change its
position at the Conference to defend whatever action it has taken, which may not
be in the UK's best interest, or may not be achievable.
Paragraph 9.2.2 states that "digital radio receivers tune across the
range
174-240 MHz". Before any further allocations are made outside of
existing bands,
it would be essential to prove this assertion. Previous experience indicates
that mass-market manufacturers rarely equip products to receive frequencies
outside of the common frequency ranges, as listeners to 'long wave' have found
to their cost.
Background
- JRC Ltd is a wholly owned joint venture between the UK
electricity and gas industries specifically created to manage the radio spectrum
allocations for these industries used to support emergency and safety critical
operations. JRC also represents gas and electricity interests to government on
radio issues.
- JRC manages 4 MHz of spectrum, of which 2.8 MHz is for PMR applications
and 1.2 MHz for telemetry and telecontrol services. JRC created and
manages a
national cellular plan for co-ordinating frequency assignments for large PMR
networks.
- JRC manages VHF and UHF allocations. These networks keep the electricity
and
gas industries in touch with their field engineers throughout the country. The
networks provide comprehensive geographical coverage to support the
installation, maintenance and repair of plant in all weather conditions on a 24
hour/365 days per year basis.
- The Scanning Telemetry Band is used by radio based System Control and
Data
Acquisition (SCADA) networks which control and monitor safety critical gas and
electricity industry plant and equipment throughout the country. These networks
provide reliable communications to unmanned sites and plant in remote
locations.
