Introduction

• Buzz Broadband is bringing all the benefits of
  the broadband future to our Wide Bay-Burnett,
  Fraser Coast region of Queensland, with a modern,
  competitive telecommunications network.
• We are building our own delivery infrastructure
  intended to not only bypass the speed and
  coverage limitations of the existing telephone
  network, but to free us from the financial
  constraints of that network.
• Buzz Broadband believes that the future of
  telecommunications will be based on the Internet
  Protocol (IP), in fact our telephone calls, TV
  channels as well as Internet data are carried
  over our IP network.
• Buzz has, therefore, invested in rolling out an
  all-IP, wireless network which delivers
  sufficient bandwidth to every user allowing the
  above, and many other bandwidth intensive
  services to be delivered.

Wireless Services

• Many customers in Buzzs regional area cannot be
  connected to ADSL
• Too far from exchange
• Copper in poor condition
• Many areas are blocked by Pair-Gain and RIM
  systems (even in new developments)
• Initial Wireless deployments Government Funded
• HiBis/Broadband Connect scheme subsidised
  customer connections to equalise cost of delivery
  of basic broadband to regional customers.
• Tremendously successful and effective in
  addressing disadvantage and creating a
  competitive marketplace with a truly independent
  infrastructure alternative.
• Demand for alternatives to Wire-Line Voice
• Buzz have found many customers would like to
  remove their copper dependence altogether

Why WiMAX?

• WiMAX is the first interoperable standard for
  Wireless Broadband Access
• Based on the IEEE 802.16-2004 and IEEE
  802.16e-2005 standards
• Currently provides fixed and nomadic
  applications, migrating to full mobility
• OFDM air interface, supporting non line of sight
  propagation
• WiMAX essentially provides true Wireless
  Telecommunications

Voice Services

• Providing voice services is key to a successful
  business model
• Whilst customers expect high speed data, they are
  not willing to pay for it!
• Voice is the premium service killer app which
  enables true competition with the incumbent
  operator
• Wireless networks typically provide either data
  only, or data with low quality voice
• Carrier Class Voice services are mandatory to
  establish any credibility with the customer
• Voice quality must be as good or better than
  existing voice offerings
• Customers are used to the Grade of Service
  currently provided by wired networks
• E.g. Circuit-Switched technology
• Network must allow Emergency Call support
• This is the only way to displace the incumbent
  since regulator requires each household to be
  able to call Emergency services during power
  outage or busy period
• This is a challenge to most wireless technologies
  the Air is a shared media !
