Future Spectrum Needs

• Wireless Access– 2G & 3G– WiFi & WiMAX (+ proprietary versions eg. iBurst)– Satellite

• Mobile Television– Multi-media Broadcast / Multicast Service (MBMS)– Digital Video Broadcast – Handheld (DVB-H)– Digital Audio Broadcasting (DAB)– Digital Multimedia Broadcast - Terrestrial (DMB-T)– Satellite Digital Multimedia Broadcasting Satellite (DMB-S)– Terrestrial Integrated Services Digital Broadcasting (ISDB-T)– QUALCOMM – MediaFLO– Satellite Digital Multimedia Broadcasting (S-DMB) – Terrestrial Digital Multimedia Broadcasting (T-DMB)


The current Australian licensing regime

Spectrum Licences are auctioned and allow operation of a band over a geographic areaThis is a requirement for Carriers because it is simple, gives certainty to spectrum availability and provides a solid foundation for network planning. This also ensures that the Quality of Service requirements that are expected by Customers can be met without issues arising from interference in the spectrum. The licences are tradeable.

Apparatus Licences are issued on a per site basis These allow for point to multipoint services subject to a fairly complex and restrictive set of legislation.Apparatus licences are generally not suitable for a national network because it is difficult or impossible to establish ubiquitous coverage on a site by site basis. New licences must not interfere with existing licences. They are in general issued for no more than five years, and can usually be renewed beyond that however this is not guaranteed.

Class LicenceUsers of class licensed spectrum have no protection from interference from other users other than changing frequency. It is expected that class licensed spectrum can be used successfully for broadband wireless in regional and rural areas in the medium term. In the longer term the viability of this type of license to provide sufficient quality of service to reliably deliver telephony service is in doubt. It is expected that more users of this equipment will come on line and there will be substantial interference especially in metropolitan areas.

Regulatory Frameworks

• Public Park – Spectrum Commons– Class Licences– PAN & LAN deployments

• Site Based – Command & Control– Apparatus Licence– Primarily point to point deployments– Not suitable for national WAS deployment, short duration

• Area Based – Private Spectrum– Spectrum Licence (national / major area, long term)– Commercial WAS with QoS guarantee

• Private Park – Carriers doing the regulators job ?– Commercial service QoS problems, cannot support primary line voice– First in, best service – more competition, less service– Prime, Low density / Remote, Remote – all competing out of the Cities


Optus Position

• Protection of Existing Investments– Commercial WAS with QoS guarantee to existing Customers– Extensive existing investment terms to provide commercial return

• Protection of International Satellite Links– Coordination of frequencies internationally– Adherence to ITU standards

• Commercial Viability of Equipment– Provision of Scale by adhering to ITU standards in Worldwide Markets for both network and

customer equipment

• Customers Expectation of Roaming– Customers expect services (and CPE / Terminal Equipment) to operate nationally and

internationally

• Commercial Viability of Future Spectrum Investments– Requirement to provide a commercial return for specific Customer services– Investment to provide known commercial return for practical market penetration
