WiMAX Certified Products
What is WiMAX Forum
Certification bringing?
• A greatly improved business case opportunity
– Certified, standards-based interoperability brings lower
equipment costs and larger markets
– Multiple vendors and greater choice of devices
– Increased operator confidence
– Target $250 for indoor self-install CPE
• Both a competitive and a complementary technology
– Can backhaul other technologies (e.g. WiFi hotspots)
– Overlay mobile networks
– Adding capacity to mobile connectivity
• Evolutionary technology from a common base
– A catalyst for convergence and converged terminal devices
– Supporting a variety of operational scenarios

The WiMAX Forum™
• The WiMAX Forum, founded in April 2001,
brings together leaders in the communications
and computing industries to drive a common
platform for the global deployment of IP-based
broadband wireless services
• The WiMAX Forum will certify products for
conformance and interoperability based upon
the IEEE 802.16 and ETSI Hiperman standards
– Certification begins July 2005 !
• The WiMAX Forum is also now addressing the
complete end-to-end “ecosystem” for BWA

WiMAX Forum spectrum objectives
• To promote flexible management of spectrum to
enable volume deployment of WiMAX Forum CertifiedTM
products
– Two licensed band ranges
• 3.3-3.8 GHz
• 2.3-2.7 GHz
– One license-exempt band range
• 5.725–5.85 GHz – Available with higher EIRP
(4W over 20 MHz) for outdoor use
– Each range will be covered by a single radio
• Flexibility for vendors to address national situations with their
products
• To promote additional spectrum below the 2.5 GHz
band for Mobile broadband applications
– 30 MHz or more per operator for “true” broadband

Membership of the ITU
• The WiMAX Forum Joined the ITU as a Sector
Member in Dec. 2004
– ITU-R (Radiocommunications) & ITU-D (Development)
• “International Organisation” membership
category, independent of any Member State
– The Forum can now send representatives and input
contributions, but like other sector members cannot vote
in the approval process of output documents
• Forum members also attend as delegates of their
national delegations and/or as representatives of
their company (if it is a sector member)
• ETSI / IEEE are also ITU members so some
coordination on relevant issues is useful

The European sub-group of
RWG
• The range and complexity of issues specific to
the European spectrum and regulatory
environment have necessitated the creation of a
European sub-group of the WiMAX Forum RWG
– Chair: Barry Lewis, Redline Communications
• Engagement in CEPT, ETSI and European
Commission discussions
• Dialogues with individual national regulators
• Regular Face-to-Face meetings, supported by
continuous e-mail contacts

Broadband Wireless Access
system deployed in the band
5725 - 5875 MHz
WiMAX Forum imperatives for
the 3.4-3.8GHz band in Europe
• Adequate spectrum in 3.4-3.8GHz to
support high quality broadband services
• Large enough spectrum blocks (per operator)
to allow broadband service innovation
• Regulatory approval of “nomadic” use
in fixed service bands
• Power levels sufficient to support indoor CPE
• In recent months a number of European
countries have issued public consultations
relating to this frequency range

Via ECC Decision ECC/Dec/(05)05, CEPT has “designated” this

arrangements, subject to market demand and national licensing
schemes
The WiMAX Forum is seeking a “technology neutral”
regulatory regime to allow operators to choose the
technology best suited to their business model and business
case

Conclusions
• The WiMAX Forum is actively engaged at
global, regional and national levels to secure a
globally consistent spectrum environment for
Broadband Wireless Access
– Including for WiMAX Forum Certified systems
• The Forum has a strong Regulatory Working
Group team to support WiMAX Forum spectrum
and regulatory activities
• 5.8GHz, 3.5GHz and 2.5GHz remain the key
focus at the present time
• The ITU has an important role in enabling the
right spectrum and regulatory environment
– And we are especially pleased to have been
welcomed as an ITU-R/ITU-D Sector Member !
