Wireless local loop:
current status and future outlook
Licences for the deployment of public
wireless local loop (WLL) networks in the 3.4-3.6 GHz frequency band were
awarded by ARCEP on 25 July 2006, following a call for candidates launched in
August 2005.
These licences include deployment
obligations, whose first inspection deadline was 30 June 2008.
Over the course of summer 2008, ARCEP
performed an audit on these deployment obligations. It also held hearings to
achieve its analysis of the current status and future outlook for wireless
local loop projects in the 3.4-3.6 GHz frequency band.
The goal of this document is to render an
account of this audit and to provide a summary analysis of the situation, based
on the elements supplied by the players.
This report is composed of three parts:
·
a precise
inventory of rollouts as of 30 June 2008;
·
an analysis of
the technological and economic factors that have affected rollouts;
·
an updated view
of the wireless local loop’s development prospects.
Between 2004 and July 2006, the Authority
held a call for candidates for regional wireless local loop licences in the
3.4-3.6 GHz frequency band in Metropolitan France and in the overseas regions
of Guyana, Saint-Pierre and Miquelon and Mayotte.
Following the public
consultation conducted by the Authority in 2004, whose purpose was to identify
the market’s interest in the wireless local loop in the 3.4-3.8 GHz
frequency band, the call for candidates for wireless frequency licences in the
3.4-3.6 GHz frequency band was launched in 6 August 2005 after publication by
the Ministry of Economy, Finance
and Industry of the order concerning the procedures and terms for awarding
frequency licences defined in ARCEP Decisions nos. 05-0646 and 05-0647 of 7
July 2005.
The Authority began the selection
procedure with a preparatory phase which included the submission of 175 letters
of intent from the candidates on 14 October 2005. This stage was to allow those
players interested in being awarded a licence to access the wireless local loop
to explore the different possibilities for sharing the use of the frequencies.
Once this stage was completed, in early
January the Authority established an inventory of the submissions to be able to
assess the possible scarcity of frequencies on a region-by-region basis. The 45
submissions received led to a determination of scarcity on 10 January 2006 in
22 regions in Metropolitan France, in Guyana and Mayotte, where selection
procedures had been officially launched. No scarcity of spectrum resources was
determined for Saint-Pierre and Miquelon. There were ultimately 35 players
selected as candidates.
Among these 35 candidates, 15 players
were selected, including six conseils régionaux (regional
councils), each with a 15MHz duplex. The selection procedure was based in equal
part on the following selection criteria:
·
contribution to
the national broadband development plan;
·
the
project’s capacity to stimulate broadband market competition;
·
the sum of the
fee that the candidate was willing to pay.
The selected candidates agreed to
large-scale rollout commitments which were included as obligations in the terms
of their licences.
The goal of the audit performed on 30
June 2008 was to assess the degree to which the licence-holders were meeting
their commitments, particularly in terms of deployment objectives.
This audit also provided an opportunity
to take an inventory of wireless local loop deployments and to get an updated
view of the players’ plans with respect to ADSL dead zone coverage and
the development of roaming services.
The licences awarded by the Authority
concern frequencies that can be traded in the secondary market. This system has
been widely used by the original licence-holders. The transfers include not
only a transfer of rights but also of the original licence-holder’s
obligations. The following paragraph lists the licence-holders as of 30 June
2008 which were the subject of the audit.
As of 30 June 2008, the number of
licence-holders in Metropolitan France had practically doubled (19
licence-holders of which 14 local authorities and 5 operators) compared to the
10 original licence-holders (6 regional councils and 4 private operators).
The mechanisms of the secondary market
have been employed chiefly by the regional councils to cede their rights to the
conseils généraux (departmental councils). As a result,
the number of local authorities involved has increased considerably following
the transfers of frequency usage licences. 14 local authorities currently hold
a frequency licence.
In Alsace, the Conseil régional
transferred its licence to the Conseils généraux of the
Haut-Rhin and the Bas- Rhin in their respective départements. In
the same vein, in Aquitaine, the Conseil régional ceded its
licence to the five Conseils généraux (Conseils
généraux of the Gironde, the Dordogne, the Landes, the
Lot-et- Garonne and the Pyrénées-Atlantiques). Le Conseil
régional of Poitou-Charentes, which was initially a licence-holder
for the entire region, transferred a portion of its licence in the
Deux-Sèvres département to the firm, Altitude, and kept
its licence to the Charente region’s three other départements.
In Brittany, the Conseil régional ceded its licence to the Conseils
généraux of the Côtes d’Armor, the
Finistère and Ille-et-Vilaine in their respective départements,
and to operator Nomotech in the Morbihan département. The Conseil
régional of Burgundy transferred a portion of its licence to the
NiverLAN joint union in the Nièvre département, keeping
its licence to the rest of the region. And, finally, Corsica kept its original
licence.
The private operators that are
licence-holders are HDRR France, Altitude Wireless, Bolloré
Télécom, SHD and Nomotech SHD. HDRR France (formerly HDRR
multi-regions and HDDR Centre Est) has licences in 11 regions (Lower Normandy,
Centre, Champagne-Ardenne, Upper Normandy, Languedoc-Roussillon, Limousin,
Lorraine, Nord-Pas-de-Calais, Pays de la Loire, Picardie, Poitou-Charentes).
The company acquired all of the wireless local loop frequency licences from its
wholly-owned subsidiaries, HDRR Multi Regions and HDRR Centre- Est, on 30
November 2006. Altitude Wireless has a licence in 13 regions (Alsace, Auvergne,
Lower Normandy, Burgundy, Centre, Champagne-Ardenne, Franche-Comté,
Upper Normandy, Lorraine, Midi-Pyrénées, Nord-Pas-de-Calais, Pays
de la Loire, Rhône-Alpes) and Altitude Télécom has a
licence in the Deux Sèvres département. The company, Altistream
(renamed Altitude Wireless), a wholly-owned Altitude subsidiary, acquired all
of its wireless local loop frequency licences from the firm Maxtel, of which
Altitude controls 50%, on 7 June 2007 for 11 regions, and on 16 October 2007
for the two remaining regions: Franche-Comté and Rhône-Alpes.
Bolloré Télécom holds licences in 12 regions (Aquitaine,
Auvergne, Brittany, Corse, Franche-Comté, Ile-de- France, Upper
Normandy, Limousin, Midi-Pyrénées, Picardie,
Provence-Alpes-Côte d’Azur, Rhône-Alpes) and SHD (Neuf and
SFR subsidiary) in 2 regions (Ile-de-France, Provence-Alpes-Côte
d’Azur). And, finally, the firm Nomotech SAS has acquired a licence for
the Morbihan département.
After the 30 June 2008, ARCEP approved
the HDRR France plans to transfer licences to Bolloré
Télécom in 8 regions. At the outcome of this transfer, HDRR
France still held licences in three regions (Picardie, Languedoc-Roussillon and
Limousin) and Bolloré Télécom became the licence-holder in
20 of the 22 regions in Metropolitan France (all except Alsace and Burgundy).
These transactions illustrate two trends:
first, operators’ restructuring which has enabled the emergence of a
virtually nationwide operator and, second, a fragmentation at the departmental
level created by local authorities.
Lastly, operator IFW, which holds a
national licence whose deployment deadline is later than the rest (December
2008), will be audited at a later time.
Licence-holders’
use of wireless local loop frequencies in the 3.5GHz band as of 30 June 2008
In 2006, licences were also awarded in
the geographical zones outside Metropolitan France. The following licence
holders were thus also subject to the audit:
·
France Telecom
(Saint-Pierre and Miquelon, Guyana and Mayotte)
·
Guetali (Mayotte)
·
Guyacom (Guyana)
·
Omtel SPM
(Saint-Pierre and Miquelon)
·
STOI (Mayotte)
·
Mediaserv
(Saint-Pierre and Miquelon)
The audit of licence-holders’
compliance with the terms of their wireless local loop frequency licences,
which was performed two years after these licences were awarded, allows the
Authority to obtain an inventory of the first rollouts in the 3.4-3.6 GHz
frequency band. These rollouts involve a large number of sites (more than 500
operational sites). Commercial offers are also available and the first
customers (around 4,000 residential and business customers) have been connected,
especially in the less densely populated areas. Deployments nevertheless remain
small scale compared to what had been planned in 2006, and there are still
sizeable disparities from region to region (some are equipped with a large
number of sites while others have none) and from one licence-holder to the
next. On the whole, the current state of WLL deployments is well below the
licence-holders’ initial commitments.
A total 526 sites have been deployed, of
which 512 are operational with a commercial offering either available or
scheduled to launch in the last quarter of 2008. HDRR France and Altitude
Wireless are reporting several thousand customers connected (business and
residential).
Three licence-holders have met their obligations
in terms of the number of sites to be deployed: the Conseil
général of the Haut-Rhin, the NiverLAN joint union
(Nièvre) and the firm Nomotech SAS (Morbihan).
Half of the local authorities that have
WLL licences are involved in a large-scale WiMAX rollout for which they have
appointed a technical partner and mobilised substantial financing, even if no
site has yet to be deployed. In many cases, the objectives for these projects
exceed those contained in their licence (in number of sites and breadth of
coverage).
The first commercial offers are
available. They are aimed at both residential users
(including services running at 2 Mbps downstream, 512 kbps upstream or 1 Mbps
downstream, 128 kbps upstream) and businesses (including services delivering 4
Mbps downstream, 1 Mbps downstream and 8 Mbps symmetrical), providing broadband
internet access at the same price as ASDL services, along with unmetered voice
services for residential users for an additional €10 euros a
month. Several thousand customers, both residential and business, already
subscribe to these offers.
A regional inventory of rollouts reveals
that of the 22 regions in Metropolitan France, 16 are equipped with their first
sites and commercial offerings – the first rollouts having been achieved
by private sector licence-holders in 13 regions and by public authorities in
the other three. Pioneer deployments have taken place in a large percentage of
the country, albeit in a disparate fashion.
Figures on the rollouts are presented in
the tables below, which reveal, among other things that:
·
SHD has achieved
significant deployments in its two regions. Commercial launch is scheduled for
September 2008 (Numéo), and the wholesale offering has been available
since March 2007;
·
Altitude Wireless
has installed 212 sites in 7 regions and markets a commercial offer in four of
its 13 regions;
·
HDRR France has
transferred its licence in 8 regions. The company has met its obligations in
terms of number of sites to be deployed in three of these regions (Upper
Normandy, Pays de la Loire and Poitou-Charentes) and performed rollouts (63
sites) in the other regions, with the exception of Lower Normandy. In the three
regions where HDRR France has kept its licence, significant rollouts have taken
place in the Limousin where a commercial service is available (Numéo);
·
Bolloré
Télécom is testing its equipment and has deployed trial sites in
one of its 12 regions;
·
Nomotech SAS has
deployed two sites in accordance with its obligations as of 30 June 2008, and
the commercial launch of its services was scheduled for summer 2008.
The following tables provide a summary,
by licence-holder and by region, of the extent to which licence-holders’
obligations had been met as of 30 June 2008 in terms of:
·
scale of
deployment (number of sites);
·
proper use of
frequencies. This obligation translates into the presence of at least one
operational site and the availability of a commercial offering in each département.

The situation from one
operator to the next is very disparate, with some licence-holders having not
yet begun their deployments while others are altering their strategies, such as
HDRR France which, although it had deployed sites, transferred 8 of its 11
licences to Bolloré Télécom which is continuing its trials
and waiting for terminal equipment to be available in large volumes before undertaking its rollouts. SHD
has completed around half of its planned deployments, and has been marketing a
wholesale offer since March 2007.
And, lastly, Altitude Wireless is
continuing its rollouts but only as part of projects financed by local
authorities (whose role in the development of the wireless local loop is
addressed in section 2.3.5).
Some local authorities, notably the Conseil
général of the Dordogne and the overseas collectivity of
Corsica, have opted for another broadband access technology – namely dead
zone subscriber connection points or NRA-ZO (Nœuds de Raccordement
Abonnés Zones d’Ombre).
Deployments in Guyana have been achieved
chiefly by Guyacom (5 operational sites and some 15 businesses connected) and
France Telecom (2 sites installed but not operational). In Mayotte, Guetali has
met its obligations and has a base of around 100 business customers. In
Saint-Pierre and Miquelon, two France Telecom sites are operational.
The results presented in the previous
chapter provide a quantified illustration of wireless local loop deployments
– clearly revealing the disparities amongst licence-holders. The goal of
this chapter is to present the elements supplied by licence-holders in their
responses which justify the differences in the status of their projects’
timetables.
The chief reason for being behind
schedule cited across the board is terminal equipment delays in terms of both
availability and technological maturity. This factor has a more or less significant
impact on rollouts, depending on the service (fixed or roaming) and the planned
business model.
The first section in this chapter
examines the technological maturity and availability of the equipment. The
second paragraph then assesses the impact on business models and explores the
other factors that influence these models.
The technologies currently employed to
develop the wireless local loop in the 3.4-3.6 GHz frequency band belong to the
802.16 family of standards defined by the IEEE and referred to commonly as
WiMAX (Worldwide Interoperability for Microwave Access). Only the two
latest versions (d and e) are currently being used.
• 802.16d version of WiMAX
enabled connection of the first customers in rural areas
Version 802.16d has proven itself as a
technology that works for delivering a fixed WLL service. It had the advantage
of being mature and available. This technology was used for pioneer fixed
rollouts back in 2006 and later by local operators developing their own
equipment based on this standard.
• …but the market
worldwide shifted to the more promising 802.16e standard
Market players around the globe, both equipment
manufacturers and operators, have switched to the next version of WiMAX
technology, namely 802.16e. Introduced later than anticipated, this technology
– which enables roaming and announces better performance along with
economies of scale at the global level – proved persuasive for most
market players, including those wanting to provide a fixed service.
Mobile equipment manufacturers in
particular began developing 802.16e-based products, and the entire market is
now centred around the technology.
Meanwhile, version 802.16d is currently
the focus of developments by only a handful of local players and by
manufacturers offering hybrid 802.16d and 802.16e products that enable current
installations to make the transition.
Operators in France thus elected to
follow the same path as the global market.
• First 802.16e-based
deployments are underway …
With the exception of a few local
operators, current deployments are all being performed using the 802.16e norm,
including those by operators whose first rollouts were based on 802.16d.
As it stands, a great many manufacturers
are able to supply a large volume of base stations and terminals for fixed
usage (with rooftop antenna).
The terminal equipment needed to enable
roaming usage (PCMCIA cards) are just now becoming available.
• … but 802.16e
technology does not yet deliver the announced level of performance…
According to operators, the performances
by currently available equipment are below forecasts. In particular, coverage
is 10% to 20% lower for an equivalent number of base stations, and indoor use
is highly compromised by the equipment’s lack of maturity. Rollout budget
forecasts were thus revised as a higher
13/19 number of base stations is needed
to achieve the same coverage as what was stated in the licence-holders’
submissions.
In addition, according to one operator,
the equipment’s current state of maturity still makes it impossible to
provide a high quality telephony service using 802.16e.
• …and the equipment is
not interoperable
One major obstacle cited by the WLL
frequency licence-holders is the lack of interoperability between the terminals
and the base stations employed for fixed usage, and no doubt for roaming as
well. This lack of interoperability forces the players to perform more costly
rollouts using a single supplier, added to which investments made to date may
well be undermined if future equipment upgrades are needed.
WiMAX Forum certification of technical
solutions has fallen behind schedule, with the timetable set in July 2006
indicating certification of the first equipment by the end of that year. This
first wave of certification for equipment operating in the 2.6 GHz frequency
band did not, in fact, occur until June 2008, and certification of 3.5 GHz-band
equipment is now scheduled for late 2008 or early 2009.
This roadmap illustrates not only delays
in manufacturing but also the fact that the development of equipment operating
in the 3.4-3.6 GHz frequency band is closely bound up with the development of
analoguous equipment operating in the 2.6 GHz band.
The future of this technology goes beyond
just France, of course, and will be decided at the global level according to
the leading manufacturers’ and operators’ commitments to
large-scale projects in the 2.6 GHz and 3.5 GHz frequency bands.
When the WLL licences were delivered, two
types of project had been identified for use of the 3.4-3.6 GHz band:
·
contribution to
developing broadband coverage nationwide, particularly in those zones not
covered by ADSL;
·
innovative
endeavours in the area of roaming between fixed and mobile broadband,
particularly in densely populated areas.
Both types of project are still on the
table. Current wireless local loop deployments are focused on fixed usage, with
pioneer rollouts and the launch of commercial services having been supported by
public-initiative networks, for projects in sparsely populated areas, as a
complement to zones covered by ADSL. WiMAX technology is, however, having to
compete with new technological solutions such as the NRA-ZO (dead zone
subscriber connection points) as well as proven technologies such as satellite
and Wi-Fi.
In densely populated zones, as a solution
for delivering broadband wireless roaming, WiMAX provides the market with
innovative services between fixed and mobile broadband. But the below-par
performances of the equipment thus far, the lack of suitable terminals and the
lack of interoperability have all contributed to delaying rollouts.
These points are examined below.
Licence-holders that have been working to
equip dead zones underscore the fact that public-initiative networks have been a
significant driving force in WLL rollouts in these areas. The majority of
launches in Metropolitan France in fact occurred as part of a public-initiative
network.
Players with a WLL licence in the 3.5 GHz
frequency band confirm the fragility of a business model for operations solely
in dead zones and reveal that, without public financing, this model will not
likely be viable. Furthermore, the economic area is stretched to the point that
it cannot sustain two players in the same dead zone. As a result, regardless of
the technology used, when a public-initiative network is underway, other
players’ rollouts are discouraged, and so preventing the introduction of
a competing offer.
HDRR France’s withdrawal
demonstrates that it was unable to achieve economic viability with a
multi-regional coverage model aimed only at those zones still not covered by
ADSL. In addition to delays with the technology, the reasons cited by the
operator are the introduction of the NRA-ZO solution and the fragmentation of
the target market which resulted in the multiplication of public-initiative
networks.
The extension of ADSL coverage enabled by
the development of the NRA-ZO (dead zone coverage) solution reduces the size of
the potential zone to be covered by WLL technologies. The NRA-ZO solution is
positioned as a direct rival for WiMAX from an economic standpoint. The NRA-ZO
connection points are being installed on the border of zones covered by ADSL.
On the whole, a dead zone subscriber connection point installed in these zones
captures around 25% of the lines in the target market, without reducing the
quantity of WiMAX equipment (particularly base stations) that needs to be
installed to ensure coverage in the remaining areas. As a result, the economic
potential of WiMAX is seriously undermined while its required investments in
infrastructure remain the same.
Furthermore, some licence-holders pointed
out that the fragmentation caused by public-initiative networks reduces the
size of the potential market for a national player, and so the potential
economies of scale. This fragmentation also undermines the ability to achieve a
homogenous and consistent marketing model. In particular, when marketing a
wholesale offer, this fragmentation discourages ISPs from offering a service
that would not be national or, at least, as widely available as possible. The
customers for these wholesale offers are thus local ISPs (rarely operating beyond
the departmental or multi-department level) which, for a national operator,
generates additional costs for structuring and connecting to the information
system.
Public authority financing for dead zone
coverage projects helps rebalance this business model. Operators nevertheless
indicate that the financing is sometimes accompanied by targets that well
exceed the initial obligations contained in their WLL frequency licences.
Moreover, financing that takes account only of the initial investment may not
be enough to cover the cost of future technological developments.
And, finally, operators with a WLL
licence underscore the fact that public-initiative network contract models are
often complex and that the generally long timelines cannot be managed efficiently
so as to keep up with technological developments.
This being the case, local authorities
have a central role to play in the digital development of their region in
general, and in WiMAX deployments in particular: this point is examined in more
detail in section 3.3.2.
2.2.2. WiMAX for ISPs’ national
roaming projects
WiMAX technology, and the 802.16e
standard in particular, was developed to enable roaming, and even mobile
broadband access. By choosing this version of the norm, some operators’
licence submissions included the fact that they wanted to help develop
broadband market competition nationwide, and particularly in densely populated
areas, with innovative roaming solutions.
Operators pointed out that the roaming
equipment (PCMCIA cards, USB keys) required was in very short supply, and even
non-existent when it came to 3.5 GHz chips embedded in PCs, added to which this
equipment – whose production was already some 24 months behind schedule
– is not interoperable.
The combination of
these two factors is currently preventing operators from deploying networks
that enable roaming services under viable economic conditions (the lack of
interoperable equipment prevents the creation of a mass market and puts a halt
to investments by operators which will undoubtedly have to upgrade their base
stations once the terminal equipment has been certified).
Furthermore, projects in the 3.5 GHz band
aimed at delivering roaming services are now having to contend with the
development of 3G mobile broadband offerings and, in future, with new projects
born of the upcoming availability of the 2.6 GHz and 800 MHz frequency bands.
The following chapter presents the
players’ updated perspective on the development outlook for the wireless
local loop, and identifies a number of factors that will help stimulate its
development.
3. Outlook for
projects in the 3.5 GHz frequency band
This chapter is devoted to the outlook
for wireless local loop projects in the 3.5 GHz frequency band, as presented by
the players. The first part contains an analysis of the role that the WLL in
the 3.5 GHz band will play in the broadband access market. The second part
describes the factors that will be key to its development.
3.1. Role of the
wireless local loop
Despite a rocky start, the audit
performed with the players confirmed the existence of projects based on two
very different models:
·
nationwide
projects for delivering roaming services in densely populated zones;
·
regional digital
development projects.
The recent consolidation of operator
Bolloré Télécom illustrates a tendency to develop a
national strategy aimed at delivering roaming broadband wireless internet
access in densely populated areas, and confirms the market’s interest in
developing this type of project.
The Bolloré Télécom
wireless local loop project underscores the operator’s interest in WiMAX
technology. The project involves sizeable investments and aims to build a
strong nationwide brand with commercial offerings that benefit from economies
of scale and consistent service thanks to the national dimension.
Providing a wireless local loop service
nationwide would prove an appealing alternative or complementary solution to
DSL technologies, particularly for roaming access to services.
To succeed, however, this type of
business model would need to forge itself a place between fixed broadband
access offers and mobile broadband access offers.
There does not appear to be a viable
business model for using wireless local loop technology in the
3.5 GHz frequency band only for
delivering fixed broadband access in zones not yet covered by ADSL or cable.
Given that the rollouts performed as part
of a nationwide ISP model will initially target densely populated zones,
covering dead zones with services in the 3.5 GHz band seems an unlikely
prospect in the short to medium term, outside a local public-initiative network
project.
Here, WLL technologies in the 3.5 GHz
frequency band could contribute to achieving national coverage as part of
projects that employ a combination of technologies. It does seem that no single
technology – whether wireless local loop, wireline technologies or
satellite systems – can single-handedly meet the goal of expanded
coverage.
It is only by examining the local
situation on a case-by-case basis that the optimal combination of technologies
can be found to resolve a digital regional development problem.
Each alternative to the wireless local
loop has its own set of advantages and disadvantages. The NRA-ZO solution, for
instance, which targets dead zones, does not always meet the client
enterprise’s needs in terms of service as most businesses require
guaranteed symmetrical bitrates. Satellite solutions have inherent technical
limitations and remain costly for the speeds they deliver, although
technological progress is expected in the coming years, as is a decrease in
price. Wi-Fi is an easy, fast and inexpensive solution to install, but it is
only temporary – one of its weaknesses being that it cannot guarantee
quality of service. And, finally, optical fibre solutions which are competitive
in densely populated zones, only serve as a collection network component in
more sparsely populated areas and, using WiMAX as the access solution,
constitute an intermediate stage in delivering fibre to the user.
The issue of regional digital development
is examined briefly in this document, but will be the subject of a detailed
ARCEP report, in accordance with the law on modernising the economy (Loi de
Modernisation de l’Economie).
1. Development factors
2. Global production situation
Widespread use of the wireless local loop
in the 3.5 GHz frequency band depends to a considerable extent on the
large-scale and global availability of WiMAX 802.16e standard-compliant
equipment that is interoperable and that performs as expected.
This availability depends a great deal on
the existence of a large enough worldwide market that projects in France alone
cannot create.
All of the WLL frequency licence-holders
emphasised the impact of production delays in WiMAX equipment for the 3.5 GHz
frequency band.
802.16e equipment for fixed usage is currently
available, albeit carrying certain concerns over its interoperability with
future hardware. Certification of the first roaming-compatible equipment in the
2.6 GHz band was the subject of a WiMAX Forum communiqué in June 2008,
and equipment in the 3.5 GHz band is expected to be certified in late
2008-early 2009. The timetable is thus a positive sign of the development of
WiMAX technology.
According to the manufacturers, equipment
in the 3.5 GHz band will become available 6 to 12 months later than 2.6 GHz
band equipment. This means that both public and private sector players will
need to establish a technological plan that depends on developments around the
globe, and so contains a portion of risk.
One key to successful projects will thus
be the massive release of interoperable equipment, for both fixed and roaming
usage. Its interoperability will lift the current restriction of having to rely
on a single supplier.
In addition, operators need to continue
to work to promote the development of the equipment, particularly by taking an
active part in initiatives such as those being undertaken by the WiMAX Forum.
As it stands, equipment performance
levels vary from one manufacturer to the next. Of particular note is the fact
that some manufacturers’ products do not provide high enough quality to
deliver a telephone service. Manufacturers and operators are working together,
notably within the WiMAX Forum, to improve the hardware’s performance.
The next generation of base stations and terminals is expected to deliver more
robust wireless performance. Ongoing progress towards producing more robust and
high performance equipment is thus another crucial factor for the future
success of WiMAX in the 3.5 GHz band.
802.16e technology has the advantage of
being the focus of production worldwide, which will only materialise from
demand for large-scale projects. Uncertainties at the global level thus have a
direct impact on equipment availability. In addition, the development of
WiMAX-based equipment is focusing first on the
2.6 GHz band. WiMAX in this frequency
band has a relative lead over 3.5 GHz-band equipment because of the
geographical scope of the projects (in Asia and the United States). As a
result, manufacturers naturally began by developing technical solutions in the
2.6 GHz band, which meant that 3.5 GHz band WiMAX developments were forced to
take a backseat.
Mass production therefore depends, first,
on manufacturers’ commitment and, second, on the existence of
operators’ large-scale projects.
3.2.2. The role
of local authorities in digital regional development projects
In the short and medium term, the use of
WiMAX in the 3.5 GHz band for covering ADSL dead zones will be shaped largely
by their inclusion in public-initiative networks.
The crucial factors that can help
encourage the use of this type of technology are:
·
the availability
of a backbone network, e.g. optical fibre, which can be accessed under neutral
and non-discriminatory conditions by all operators, allowing them to deploy
their local loop quickly and at a lower cost. Investments induced by the
construction of a backbone network have the added advantage of being lasting;
·
the availability
of high points.
Local authorities’ commitments to making
this type of lasting investment is one of the factors that will enable the
deployment of wireless local loop technologies, while not being specific to
WLL.
Furthermore, the role
played by the wireless local loop in the 3.5 GHz band as part of a combination
of technologies needed for digital regional development can be assessed at the
local level, based on an inventory of the zones concerned and an
technical-economic optimisation aimed at determining the solution that is best
suited to each case.
If one of the solutions
identified includes WiMAX, whether or not the local authority has a WLL
licence, the deployment of a digital regional development project based on
WiMAX could be facilitated if the local authority takes account of the
operating costs and the costs generated by technological developments (evolving
standards and equipment upgrades) during the financial planning stage.
Conclusion
Over the course of summer 2008, ARCEP
performed an audit of the rollout obligations for public wireless local loop
networks in the 3.4-3.6 GHz frequency band. The hearings that were held
concurrently made it possible to assess the circumstances affecting the
development of wireless local loop projects in the 3.4-
3.6 GHz band and to obtain an updated
view of the market.
The first point noted is the actual
deployment of the wireless local loop in over 500 sites, along with the
availability of commercial offers and several thousand residential and business
customers. Rollouts remain still relatively small-scale, however, and currently
fall well short of the licence-holders’ original commitments. This
situation can be explained in large part by the undeniable production delays
worldwide of interoperable 802.16e standard equipment, whose outlook is more
promising and towards which the market is currently oriented.
Widespread use of the wireless local loop
in the 3.5 GHz frequency band depends to a considerable extent on the
large-scale and global availability of WiMAX 802.16e standard-compliant
equipment that is interoperable and that performs as expected. This
availability depends a great deal on the existence of a large enough worldwide
market that projects in France alone cannot create.
It emerged from the players’ views
on the outlook for their projects that the wireless ISP model devoted to
providing nationwide roaming broadband services is still very much on the
table. To succeed, this type of business model will need to forge itself a
position between fixed broadband and mobile broadband access offers.
Among other things, wireless local loop
technologies in the 3.5 GHz frequency band could contribute to regional digital
development projects, as one component in a combination of technologies. It
does seem that no single technology – whether wireless local loop,
wireline technologies or satellite systems – can singlehandedly meet the
goal of covering all of the country’s dead zones. The economic viability
of a WiMAX project aimed specifically at dead zones does, however, appear
unlikely outside their inclusion in public-initiative networks.
