Action

Item 1: Minutes of L
ast Meeting held on 18 February 2013


OSAB
42(13
)


1.

The minutes of the meeting held on
18 February 2013
previously circulated to the Board were agreed as an accurate
record for signature by the Chairman.


Item 2: Chairman’s Introduction and Matters Arising


2.

The Chairman welcomed all
members
present to the f
orty
-
third

meeting of OSAB.
A warm welcome was extended to the
OSAB Co
lleagues present.



3.

All th
e actions arising from the
meeting
on 18 February 2013
had been cleared.


4.

An O
fcom colleague briefed OSAB on the arrangements being
made for the appointment of a new Director of
the Spectrum
Policy Group.
The members expressed their appreciation for
the support given to the Committee by H Nwana whilst he was
Director of the Spectr
um Policy Group.



Item 3: Licensed shared access


5.

OSAB received a presentation on licensed shared access
(LSA) for spectrum from three Ofcom Colleagues. The
members noted that:

































LSA would grant additional spectrum rights of use in specific
bands on a
shared basis whilst ensuring a certain Quality of
Service (QoS) for all rights holders



LSA is seen as a regulatory approach to facil
itate more efficient
use of spectrum



the
application of the
LSA

framework may offer additional
spectrum access to mobile broadband services to address the
current challenges in Europe



LSA is being developed as a complementary approach to the
existing licensed and licensed exempt spectrum use



LSA as a concept was being

developed by the Radio Spectrum
Policy Group (RSPG)



CEPT has also initiated work on a Licensed Shared Access
Regulatory
Framework and the possible use of the LSA
approach to enable wireless broadband applications in the
2300


2400 MHz band



the current wo
rking definition of LSA was ‘a regulatory
approach aiming to facilitate the introduction of
radiocommunication systems operated by a limited number of
licensees under an individual licensing regime in a frequency
band already assigned or expected to be ass
igned to one or
more incumbent users.

Under the LSA framework
, the
additional users are allowed to use the spectrum (or part of the
spectrum) in accordance with sharing rules included in their
rights of use of spectrum, thereby allowing all the authorize
d
users, including incumbents, to provide a certain QoS’



in the

LSA concept the incumbent is the current holder of
spectrum rights independent of the way in which the rights
were obtained. Secondary trading and licence exempt use are
considered to be outs
ide the scope of LSA.



a number of

LSA scenarios have been developed for analysis

including

o

incumbent is a governmental user who may or may not
hold a licence

o

incumbent is a governmental or commercial user holding
a licence

o

vacant frequency band



the RSPG Wo
rking Group had met four times

o

a questionnaire had been developed to gather best
practice on spectrum sharing

o

the focus was now on writing the text of the Opinion with
a view to present the draft version to the RSPG plenary
in June to obtain approval for
public consultation

o

if approved, public consultation would take place in the
summer to gather stakeholders feedback to the draft
Opinion

o

the final Opinion was expected to be published in
November






6.

OSAB
also noted that the Radio Spectrum Policy Programme
(R
SPP) stipulated at least 1200MHz of suitable spectrum for
wireless broadband to be identified as part of the Spectrum
Inventory initiative, also mandated in the RSPP and adopted by
the Radio Spectrum Committee (RSC) in March.


7.

The RSPG Working Group on Wir
eless Broadband has also
reviewed the current allocations of spectrum in Europe within
the frequency range from 400MHz to 6GHz to establish the
opportunities for finding 1200MHz for wireless broadband. The
draft Opinion was approved at the February RSPG p
lenary and
subject to public consultation until 3 May.


8.


LSA was also being discussed within CEPT both as a general
concept and with regards to 2.3GHz spectrum release.


9.

The members offered the following comments on the
presentation:




OSAB noted that
there was an issue to be addressed with
respect to the concept of a right to use spectrum which would
require development of the option to share spectrum. OSAB
also noted that most of the spectrum in question was reserved
for military use

(particularly in

rural areas)

and thought that
work in this area could lead to harmonisation of spectrum
across the UK.



OSAB also noted that ‘quality of service’
was not a defined
term and would have different meanings, particularly between
existing users of the spectrum
and new entrants (Ofcom
agreed that there could be no guarantee within the
conventional meaning of the word with respect
to the
availability of spectrum,
a guarantee could be given as to its
quality)
.



OSAB thought that existing users of spectrum should be

identified and that Ofcom should work on guaranteeing
conditions for co
-
existence.



OSAB thought that spectrum reserved for military use should
either be paid for by the MoD or released for auction



the spectrum would have to be licensed or have
conditions
of
use
imposed on users to avoid interference problems

and allow
co
-
existence



that there was a risk of the spectrum policy getting ahead of
what is currently technically feasible



that there could be interleaving bands of white space to reduce
interference
issues



that Ofcom could have a role to play in directing the co
-
ordination of the use of shared spectrum



care needed to be taken to ensure that the implementation of
LSA did not favour any one provider of technologies



LSA needed to be seen to be adding val
ue
. If it did there
would be no need for quality of services issues to be
addressed



that LSA could be a step towards EU harmonisation



that the
anticipated
sale of spectrum by MoD was likely to be
freehold rather than leasehold



OSAB considered the issue to

be one where a global rather
than local or national view should be adopted



OSAB noted that there were a number of technical areas to
address and thought that LSA should feature on the agenda for
WRC 2015


10.

The Chairman thanked the Ofcom colleagues for the
presentation which OSAB found interesting and worthwhile. It
was agreed that a follow
-
up presentation could take place to
brief the members on the latest developments.


Item 4: Outcomes from a study on providing reliable in
-
building
coverage


11.

OSAB receive
d a presentation on the

findings of

a
yet to be
published
study on the
options for improving in
-
building mobile
coverage.
The members noted that:




Ofcom’s not
-
spots programme and the related Mobile
Infrastructure Project have primarily targeted outdoor co
verage
problems
, but indoor coverage is also important

o

indoor coverage is regularly cited as number on
e
network
-
related cause of churn

o

one operator

with coverage of 99.7% of population
indicate that 19% of their users’ regularly encounter
coverage problems at home

o

currently 70% of mobile coverage is inside buildings and
predicted to increase to 90% in the next few years

o

the 800MHz coverage obligation

targets indoor
coverage at 98% and 95% in each nation.

o

all operators have launched or announced in
-
building
solutions



indoor coverage could actually get worse

o

80% of usage is now indoors

o

22% of consumers cite more reliable data connection
and 34%
highlighted better network coverage as
reasons to switch service provider



factors improving service

o

more use of lower frequencies

o

upgraded technologies on macrocells

o

more macrocells per operator

o

specific solutions for enhancing in
-
buildings services

o

Mobile

Infrastructure Programme



factors degrading service

o

building regulations (better thermal insulation
requirements increase propagation losses)

o

smartphone sensitivity worse than feature phones

o

user expectation of minimum data rate increases with
time

o

greater

usage causes greater contention



requirements vary significantly between home users, small
offices, large multi
-
storey offices and public buildings and
campuses



current solutions which are increasingly available in all
environments


self provided Wi

Fi, carrier Wi

Fi, consumer
repeaters, intelligent repeaters, UMA, femtocells, picocells and
DAS and distributed BS



outside

in (macro and small cell) solutions provi
de an important
‘hassle free’ baseline for in
-
building coverage for consumers
but will not reliably work everywhere event when the outdoor
cell is nearby to the building



operators have an increasing range of technical options
available but remain unconvinc
ed of cost
-
effectiveness beyond
selected consumer and building segments

to drive availability, consumers and building owners need to
understand the range of dedicated in
-
building technical options
available and the scenarios where they best fit



common conc
erns emerging across in
-
building technical
options

o

small cell solutions are not yet fully integrated into
existing operator networks

o

best practice implementation of security standards in
consumer accessible small cells need to be ensured

o

multi operator sup
port and ease of switching is difficult in
low cost consumer products in particular

o

many in
-
building solutions still reasonably immature and
limited availability


12.

OSAB noted that the study made the following
recommendations for Ofcom:




consumers need assistance to navigate the choice of in
-
building solutions



spectrum is not a fundamental barrier to the deployment to in
-
building technologies and could help accelerate the adoption of
come solutions



the report recommended
Ofcom to

o

conside
r providing updates on in
-
building coverage
levels in their market reports

o

monitor appropriate openness of solutions to ensure that
consumers have a choice of suppliers for their preferred
in
-
building solution

o

assist in forming best practice implementation

guidelines
in in
-
building solutions and raise consumer awareness of

this

o

analyse the FCC position on repeaters and consider why
it does not fit the UK market


13.

the members offered the following comments on the
presentation:




that an internal network would
be required regardless of the
availability of Wi
-
Fi



that consumers needed to change
their expectations of the
services that
a network
could deliver
in order to appreciate the
problem



that the study should include information on the availability of
4G servi
ces



that access to a range of services would be controlled by tariffs



that consumers wanted access to voice as well as dat
a and
would be unlikely to regard access to voice through Wi
-
Fi as a
satisfactory alternative



that ownership of the physical
infrastructure of the network
would determine the range of services



that Ofcom should be encouraged to go into premises and
improve the standards of services



people would increasingly demand access to the full range of
services regardless of whether they w
ere at home or at the
office



that operators should be encouraged to fix network problems
before it became a matter for the regulator to address



that greater access to services would open the market up to
competition and encourage new entrants even into re
latively
small markets



that competition could only be effective
where consumers were
able to easily switch providers. The level of switching was still
very low


Item 5: OSAB Annual Report 2012/13


14.

OSAB noted that a draft of the annual report for 2012/13 w
ould
be circulated to them and interested parties within Ofcom for
comment before the end of the week. The report
would follow
the same format as the previous year


ie it would identify the
three main stands of the work carried out by the Committee
durin
g that period.
The intention was to have the report
approved for publication by the Ofcom Board for July 2013

and
members were encouraged to submit comments on the draft
.


Item 6: Any other business


15.

OSAB noted that the International Institute of Commun
ications
was hosting an event on 4G on 21 May and members would be
welcome to attend.


16.

The members noted that the next meeting would take place on
29 July and it was agreed that WRC15 should feature on the
agenda.
