MDU/MTU Market

• Multi-Tenant Units (MTUs) are buildings housing
  clusters of different business users
• Multi-Dwelling Units (MDUs) are buildings housing
  clusters of different residential users
• Multimedia distribution provides high value
  deployment opportunities for Cable, Satellite,
  and Telco operators.
• Shared components reduce deployment costs
• MDU owners and operators add revenue new revenue
  opportunities and/or increase the marketability
  of their properties.

MDU/MTU Market

• MDU Market Size Predictions are
• 14 of U.S. Households are in MDU environments
  some estimate a total of 30 million homes in
  North America are in MDU/ MTU buildings.1,2
• 90 of International Households are in MDU/MTU
  environments.2

• In many buildings, new wiring is required
• Wiring makes delivery of broadband networked
  services expensive
• Wireless solutions provide fractured deployment
• Existing agreements often limit the use of
  existing wiring
• New content and business models necessitate new
  competitive networks

Functional Requirements

• MTU MDU environments have unique
  security, channel, and capacity challenges for
  wireless solutions
• Bandwidth demand is high
• Phased deployment options
• Economics dictate multiple Units per cell
• Channelization Capacity
• Each units network needs to be secure
• Fixed and portable devices must be supported
• Coexistence with other RF systems is mandatory

6
Functional Requirements - Bandwidth

• Voice/Audio Applications
• Voice services
• 10 kbps
• High quality VOIP/Digital Audio
• 128 kbps streaming audio
• 384 kbps surround sound
• Broadband Data Applications
• Todays typical client 1Mbps
• Future access requirements up to 10Mbps
• Video Applications
• Today Future .
  
• Cable Satellite Video 2-10 Mbps Up to 10 Mbps
• DVD 10 Mbps
• HDTV 19.2 Mbps
• Digital Camcorder 27 Mbps lt15 Mpbs

7
Functional Requirements Capacity
Channelization

• Economics dictate multiple units per cell
• Video and Data applications
• 4 Units per cell non overlapping channels
• 15 Mbps per unit today
• 30 Mbps per unit in future
• Phased deployment options
• Data and voice services only
• 8 units per cell
• 1 Mbit

• Capacity model must also include
• Individual unit ad-hoc connections
• Cameras
• Game interfaces
• MP3 devices
• Other fixed networks
• Video/Audio distribution
• Total required shared capacity of 300 Mbps
• Includes adjacent cell interference

8
Functional Requirements - Scalability

• Data rate, range, shared capacity are all scalable

• Data Deployment
• 8 Units
• 30 Meters
• 2 Mbits / Unit

• Multimedia Deployment
• 4 Units
• 10 Meters
• 30 Mbits / Unit

9
Functional Requirements Multipath Environment

• MDU capacity requirements dictate the use of a
  high capacity PHY
• High capacity wide band PHY solutions will need a
  higher resolution multipath channel model
• Current channel models inadequate, model must be
  appropriate for all wide band signalling (channel
  model to be proposed)

Typical channel impulse response is not uniform
spaced echoes, but current models are
equi-spaced. Source S. Yano, Investigating

Functional Requirements Security

• Each Unit must have a secure network
• The network must provide security for
• Delivered content
• Broadband data
• Voice content
• Internal Content
• Ad-hoc
• Permanent
• Network operators will provide their own security
  - Video Audio
• Studio Approved conditional access technologies
  exist
• Fighting the security battle is not worth the
  time to market cost
• Equipment manufactures use their CA as a
  differentiator
• Security doesnt need to be added at the MDU

11
Functional Requirements Mobility

• While the focus of MDU multimedia distribution is
  viewed as a fixed device proposition today
• Future video display devices will be portable
• Microsoft Mira portable display technology
• CE manufactures are aggressively pursuing video
  tablets
• Portable connected devices must be compatible

12
Functional Requirements Co-existence

• Multiple networks and other wireless CE devices
  will exist in the home
• WiFi, Bluetooth, 2.4 and 5 GHz phones etc will be
  part of the environment
• Operation in office and home multipath
  environments
• Incumbent networks will not be discarded
• If we dont work with the old network, we're not
  deployable
• Service providers may combine networking
  technologies
• In unit gateways may utilize 2.4 or 5 GHz hand
  sets

13
Summary

• The MDU/MTU market is large
• It accounts for a large percentage of homes
• High data rates will be required in the future
  300 Mbps
• Demands cell re-use and high spatial capacity
• Individual unit security is a must
• Co-existence may be more important
• Incumbent networks will not be discarded it may
  be your neighbors!
• If we dont work with the old network, we're not
  deployable
• Success depends upon also meeting the key metrics
  for consumer multimedia devices
• QoS
• Power consumption
• Footprint
• Cost
