Strategies for Wireless Access Services

A few thoughts & comments…….

Wireless access overview of my presentation l.jpg

What is Wireless Access?

Why is the industry/market in its current state?

Current spectrum situation & emerging technologies

Some suggestions & some concerns

An underlying ‘theme’ & preliminary response(s)

Some key messages to stimulate debate

Wireless Access: ………Overview of my presentation:


Wireless access is multi dimensional l.jpg

Wireless Access: ………is multi-dimensional

Fixed line substitution

Mobility demand

Supplementary wireless access

* ‘Urban’ includes regional / rural cities & towns


Wireless access but the deployment cost factor l.jpg

Wireless Access: ……But, the deployment cost factor

Capacity Demand

Increasing capital cost

Physical Distance


Wireless access varying commercial attraction l.jpg

Metro/Urban Areas

RURAL & REMOTE AREAS ??

Wireless Access: ……& varying commercial attraction

Market Size

But…there is already notable BWA spectrum allocations in regional areas ?

3.4 GHz

2.3 GHz

Regional Areas

Delivery Costs

A natural rush toward the most profitable markets

RURAL & REMOTE Wireless Access Services

Regional 802.16 WiMAX

Metro/urban 3G WCDMA

Metro 802.16 WiMAX

ADSL/Cable Access Services

Relatively easy to deploy ….so, what’s holding things back?

802.11 WiFi

Wireless Access: ……& differing rollout timeframes

Deployment Cost

Deployment Time


Wireless access gives obvious market outcomes l.jpg

Higher-profit metro & other urban markets that are easily deployed are attracting all the competitive players

Other markets, with more complex deployment demands are largely neglected by competitive service providers – WHILE

Significant aggregated spectrum [covering many regional/rural areas] still lies unused - but inaccessible to other willing & able players !

NEXT

Wireless Access: …..gives obvious market outcomes:

…3.4GHz band

…2.3GHz band

 Clamorous demands for further spectrum allocations !


Wireless access the radio spectrum situation l.jpg

Wireless Access: …..the radio spectrum situation

Existing & Candidate Bands for Wireless Access (below 5GHz):


Wireless access some emerging applications l.jpg

Fixed WiMAX – 802.16d – certified products late-2006

3G streaming data – HSDPA (2007) & HSUPA (2008)

Mobile TV services – DVB-H, MBMS, MediaFlo – late-2007

Mobile WiMAX – 802.16e – certified products late-2007/8

Broadband satellite services – commercial availability 2008

High-altitude platform stations – commercial availability 2009

Super-3G/LTE and 4G – probably around 2010

Wireless Access: …..some emerging applications

New (broadband) wireless applications already on the horizon……..

These new applications will encourage user demand that will subsequently further strain current spectrum allocations……..


Wireless access do we need rollout targets l.jpg

Wireless Access: ….. Do we need rollout targets?

Noting that large portions of current BWA allocations continue to lie unused – especially in regional/rural areas……..

To maximise community benefit & commercial opportunity, we believe there IS justification for:

  • Use-it-or-lose-it - especially for:

    • metro/urban deployment settings, where demand is high;

    • ‘low deployment complexity’ services in ALL regions; and

    • provided some other player can demonstrate a viable alternative usage plan.

  • along with:

  • Annual instalment payments – instead of a single up-front fee:

    • to facilitate early returns (ie. ‘lose-it’ scenario);

    • to avoid diversion of vital investment capital from the initial build-out task; &

    • so smaller players are not unduly disadvantaged.


Wireless access do appropriate boundaries exist l.jpg

Too far out: may deny access by rural communities

Too far out: may delay access by regional communities

Wireless Access: ….. Do appropriate boundaries exist?

Low-population corridor?? – not always appropriate or equitable

Wireless access some other allocation issues l.jpg

Auctions should involve bidding on “notional lots”:

to allow post-auction aggregation & avoid fragmentation of lots (eg. 1.8 GHz);

to combat deliberate spoiling tactics by certain bidders; and

to avoid excessive wastage through technical ‘guard’ bands.

Spectrum lots must be of reasonable size:

to reflect the commercial viability threshold of relevant technologies; and

distinct from the (smaller) standard trading units (STUs) - that allow later trading & optimisation of spectrum holdings.

Spectrum acquisitions might be incrementally released post-auction:

requiring proof of efficient utilisation to justify each increment;

in support of a ‘use-it-or-lose-it’ regime;

balancing ‘certainty’ with ‘flexibility’;

retaining a common expiry date encourages earliest take-up– else diminishing the revenue window;

allowing delayed clearance of incumbents; and

allowing mid-term re-allocations, if appropriate.

Wireless Access: …… some other allocation issues:


Wireless access but let us be quite frank l.jpg

Wireless Access: …… But – let us be quite frank…

  • Telstra will continue to vigorously & strenuously oppose any suggestion to apply entry rules or restrictive bidding limits, because:

  • the Australian community gains most benefit from operators with sufficient capitalisation to actually deploy and deliver new services in a timely manner;

  • efficient use of spectrum relies on sufficient capital, manpower & know-how;

  • radio spectrum is an extremely valuable national economic resource.

In any case, existing provisions of the Trade Practices Act will automatically apply to all bidders at the completion of each spectrum auction to prevent anti-competitive outcomes – as per Productivity Commission recommendation.

There is no rationale for any other “special” restrictions – and a “use-it-or-lose-it” provision would discourage any hoarding of spectrum.


Wireless access an underlying theme l.jpg

The SPECTRUM LICENSING framework is very effective, but:

More prudent spectrum allocation policies are needed – to avoid the mistakes of the past (eg. 3.4GHz BWA constraints/limits, boundary definitions, neglect of regional/rural/remote areas);

There IS a place for USE-IT-OR-LOSE-IT rules – recognising the differing deployment cost & timeframe scenarios;

Other allocation strategies also exist to foster more efficient allocation & usage of radio spectrum – refer previous slides;

Readily availability & low-pricing incentives should apply to spectrum in low density rural/remote regions to encourage wider investment; and

Conventional APPARATUS LICENSING continues to be viable for “highly shared” allocations, such as for fixed point-to-point radio links.

Wireless Access: …… an underlying theme:


Wireless access some preliminary proposals l.jpg

Current spectrum allocations enough?

No – so much BWA spectrum is still lying idle but inaccessible

Key technologies & timeframes?

802.16: backhaul – now; nomadic – 2006/7; & mobile – 2007/8

3G expansion (HSDPA) – from early-2007

Mobile-TV – late-2007 – 520~702 MHz probably preferred

Amount of spectrum & number of competitors?

varies by particular technology & market – is still under study.

Candidate bands:

450~520 MHz in rural/remote areas

520~820 MHz in rural/remote areas + 4 channels in metro/urban

2010~2025 MHz in metro areas

2200~2290 MHz in metro/urban areas

2500~2690 MHz nationwide

3600~4200 MHz in metro/urban areas

Private park?

Unnecessary- we can already achieve this under current spectrum licensing regime!

Wireless Access: …… some preliminary proposals:

… mobile TV

… broadcasting bands

Already allocated to BWA:

2010~2025 MHz : regional/rural

2302~2400 MHz : nationwide

3425~3575 MHz : nationwide


Wireless access some final messages l.jpg

Additional Wireless Access spectrum DOES need to be found……but:

Minimum deployment targets should apply, to avoid ‘cherry picking’ and warehousing of critical spectrum resources – adopt use-it-or-lose-it provisions; AND

Tighter boundaries should be defined around metro/regional urban markets, so outlying rural communities are not disadvantaged; but

Low density rural/remote services may need longer deployment planning & payback periods.

Wireless Access: ….. & some final messages:


Wireless access l.jpg

Wireless Access: ………

….. some initial thoughts in regard to Wireless Access spectrum strategy.

Any questions?

…spectrum table


Wireless access current broadcasting bands l.jpg

2 datacasting channels (7MHz) in each BSA should to be re-allocated ASAP for new Wireless Access usage – eg. to encourage innovative new broadcasting-type services over new platforms.

Clearance of channels 68 & 69 should commence ASAP to further allow competitive Wireless Access

Rural/remote areas should be universally freed up for Wireless Access purposes

NEXT

Wireless Access: ………current broadcasting bands

Majority of terrestrial TV transmitters/translators/repeaters are located in populated metro/urban & regional areas – only a few local channels used in rural/remote areas.

 BSB spectrum in rural/remote areas could be released for ‘co-ordinated’ use by Wireless Access services - benefiting from the longer propagation range achievable.

…Minister’s statements

  • Two 7 MHz channels in all areas almost immediately!

  • Two additional 7 MHz channels in (say) 3 years; and

  • significant rural/remote spectrum almost immediately!

global MSS allocation: 1980~2010/2170~2200 MHz

More than 2000 3G base stations are already deployed* nationwide in the 3G TDD band by 3GIS Pty Ltd; and

Plans are underway to deploy* further 3G base stations in the FDD band over next several years.

Optus & Vodafone are envisaged to have similar deployment* plans.

Wireless Access: ………current & planned 2 GHz usage:

* NOTE: Deployment includes a significant number of existing GSM/CDMA site upgrades, as opposed to new sites.

Wireless access current 3 4 ghz usage l.jpg

Wireless Access:………current 3.4 GHz usage:

  • Total number of active 3.4 GHz P-MP base stations (as at 1 Feb 2006):

  • Telstra: 352 within 2 x 17.5 MHz spectrum sub-segments in regional areas (~2,000 customers).

  • Unwired: 428 within the overall band (3425~3575 MHz) mainly in Sydney & Melb metro areas.

Wireless access indicative trends in mobile tv l.jpg

Mobile-TV is clearly on the horizon as a future service – early commercial activities are already evident in a number of countries, including: Korea, Italy & US – as well as Australia’s own recent technical trial.

Senator Coonan has already articulated positive Govt support: “…consumers [will] be better served by media policy that encourages new content and innovative services by opening up of opportunities for television-like services over other platforms…” and “…the use of the datacasting spectrum provides the opportunity for some interesting new services for consumers and, in my view, is a key element of any media reform package…”

So, given the propagation & coverage advantages, the broadcasting services bands (including the datacasting channels) should be opened up sooner rather than later.

Wireless access indicative govt support l.jpg

Wireless Access: ………indicative Govt support:

On several recent occasions, Senator Coonan has articulated her thinking in capacity as the Government’s Minister for Communications:

  • “…consumers [will] be better served by media policy that encourages new content and innovative services by opening up of opportunities for television-like services over other platforms…” and

  • “…the use of the datacasting spectrum provides the opportunity for some interesting new services for consumers and, in my view, is a key element of any media reform package…” and

  • “…I think people should have choice. That’s why I want to get many more innovative services available on the additional spectrum that we will have available as from 2007. I have in mind that that wouldn’t be open to the free-to-air players simply because I think there needs to be new voices. So I think that the whole plan will mean that people have a much richer and more diverse media experience than is available, by having people, at least having media providers, trapped in outmoded rules in an old analogue world.” (ABC Radio National, Thurs 2/03/2006)

…broadcasting trends


Wireless access technology neutrality etc l.jpg

Spectrum Licences are never truly ‘technology-neutral’:

because of the overriding ITU-R spectrum allocation table; and

because Govt usually has some competitive service objective.

Core technical conditions are key to flexible usage:

but, development requires extensive technical knowledge; and

especially to equally accommodate differing technologies.

Understanding guard-space concepts is essential:

spectral guard-band AND geographic guard-space;

choosing an appropriate propagation model is important;

a ‘notional receiver’ definition is also essential; and

need to consider both in-band & out-of-band effects.

Wireless Access:………technology neutrality, etc:

 Essential to specify ‘notional’ Rx performance as well as Tx OOB & spurious limits.
