MDU/MTU Market

US Broadband Revenue Projections

  • 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 market1
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
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 unit’s network needs to be secure
  • Fixed and portable devices must be supported
  • Coexistence with other RF systems is mandatory

Jim Meyer, Time Domain Corporation

functional requirements bandwidth
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
      • Today’s 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 <15 Mpbs

functional requirements capacity channelization
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 the 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 capacity of 300 Mbps
    • Includes adjacent cell interference

functional requirements security
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 doesn’t need to be added at the MDU

Projector

TV

Digital Camera

Laptop

Printer

Camcorder

MP3 Player

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

Jim Meyer, Time Domain Corporation

functional requirements co existence
Functional Requirements – Co-existence
  • Multiple networks and other wireless CE devices will exist in the home
    • WiFi, Bluetooth, 2.4 & 5 Ghz phones etc will be part of the environment
  • Incumbent networks will not be discarded
    • If we don’t 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

Jim Meyer, Time Domain Corporation

summary
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 don’t 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
