Current Trials

• Hamilton Ontario
• Alcatel/Lucent equipment 802.16e 2005
• 10 BTS sites with near contiguous coverage with
  indoor CPE and PCMCIA for fixed and
  nomadic/portable capability
• Mix of urban suburban, commercial/industrial
  and residential
• Toronto Suburbs-Markham/Richmond
  Hill/Brampton/Mississauga
• Motorola equipment 802-16e 2005
• 10 BTS sites without contiguous coverage
• Mix of residential and commercial mostly in
  suburban or industrial/commercial park
  environment
• Service design including fixed outdoor modem

Initially focus on Technical Validation

• Basic Radio Performance
• Throughput (vs. distance, mobility speed, CIR)
• Interference in multi-cell environment
• Advanced antenna technology (MIMO, AAS)
• System Capacity (bps/Hz, frequency reuse,
  bandwidth)
• Portable/Nomadic Service
• CPE capability
• Handoff (inter-sector, inter-BS, Layer 2, Layer3)
• Service Feasibility
• Application level throughput (TCP/UDP)
• Internet access / VoIP

Promising Technical Trial Results

• Trials are continuing
• New features, enhancements bug fixes ongoing
  every few weeks
• Many cases coverage better than expected
• One quarter watt PCMCIA indoor reception
  throughout library
• One half watt desktop CPE omni antenna 10 kms
  NLOS
• Large variations depending on positioning
• 4 Mbps anywhere on second floor of house
• 1 Mbps on main floor on side close to base
  station
• No reception on main floor on opposite side of
  house
• Reception continuous when traveling 100 km/hr
• Instantaneous handoff between sectors and cells

Comments

• Predicting indoor coverage is problematic
• Uplink limited link budgets and throughput
• Other proprietary fixed systems have output power
  up to 2 watts directional antennas
• Significant benefit of additional uplink power
  for fixed applications
• Additional sub carriers for more throughput
• Higher modulation modes
• Network capture vs maintain sessions at cell edge
• Planning to commence roll-out in Q1 2008
• Extent and speed of construction dependent on
  financing and/or strategic partners
