WiMaxChanging the Rules of the GameBased on
the IEEE 802.16 Air Interface Standard, the WiMax
technology can provide wireless broadband
solutions in campuses, airports, city centres or
companies. This presentation will expose the
advantages and drawbacks of this technology
today and in the near future, with new dangers
and opportunities for companies in the
information transport systems (ITS) industry.

Peak Data Rate per User (Mbits/second)

• Market is converging onto the 802 standards
• WiMAX extends the coverage of Wi-Fi
• 3G best suited to high mobility/low data rate
  applications

10
Delivering Resiliency and Self-Healing Wi-Fi
Networks

• Dynamically assigns mesh route
• All possible paths are calculated
• Allows instantaneous change if new route is
  needed
• Only one route is active
• Best path continuously determined based on
  measurement of traffic, signal strength, hops
  and other parameters

Advantages of a Dual-RadioMulti-band Mesh System

• Dedicated 5 GHz radio for mesh network
• Dedicated 2.4 GHz radiofor client traffic
• Advantage 1 Clients dont contend with mesh
  radio for limited spectrum and bandwidth
• Advantage 2 Client cells are spaced using
  non-overlapping channels, TRIPLING the
  performance of single radio mesh systems
• Advantage 3 Mesh network capacity is greater
  than single radio mesh systems

With a dual radio system, client cells can be
designed for non-overlapping coverage.
12
WiMAX update

• First products are approved
• 802.16e standard is ratified
• First customer shipments are beginning for
  802.16d
• WiFi Mesh is being rolled out rapidly
• 802.16e products expected end 2006

WiMAX Enterprise Applications

• Security
• IP video surveillance

• Enterprise Campus
• Fiber extension, or
• Leased line replacement

• Warehouse
• Campus VoIP

• Branch Office
• Leased line replacement

15
Threats

• Replacement of UTMS / 3G
• Replacement of fiber
• Replacement of lease lines
• Replacement of CATV or ADSL
• Replacement of indoor CAT 5/6 cabling
• Self installable CPE
• New companies entering your space
• Customer demand for WiMAX solutions

16
Opportunities

• Every base station will require a cable
  connection
• Every mesh portal will require a cable connection
• Bandwidth of fiber is much higher than radio
• But Radio is a nice backup
• New potentional customers are addressable when
  WiMAX will become available in rural areas
• New solutions will become available for
  innovative companies
• The new networks are based on IP

17
United Nations World Food Program

• Challenge
• To provide voice and data communications in
  disaster relief situations. To reduce these costs
  by replacing multiple VSAT links into each camp.
• Solution
• Tsunami Quickbridge 11 point to point links to
  connect camps up to 20km apart. A single high
  bandwidth satellite link is now able to serve
  multiple sites. Currently the UN have replaced
  over 60 VSAT links enabling budget to be utilized
  in more critical areas.
