requirements for the wireless home network
Requirements for the Wireless Home Network
  • Support for QoS of real time streaming of A/V content
  • Net bitrate over 30 Mbits/s (Digital Video Camcorder)
  • Ad Hoc Networking (Direct Mode)
  • Self configurable (no network or frequency planning)
  • Security and Privacy
  • Connection to wired 1394 devices and clusters (bridge)
  • Plug and Play
  • Low Power for Mobile Terminals
  • Interoperability of devices from different manufacturers
  • Enough spectrum for highly populated urban areas
scenario s for the wireless home network
Scenario’s for the Wireless Home Network
  • Connection of wired clusters (e.g. between different rooms)
  • Connection of wireless stand-alone devices to the network (e.g. view a camcorder movie on the TV)
  • Categories :

conclusion and recommendations
Conclusion and Recommendations
  • HiperLAN / 2 Specification fulfills our requirements
  • We need the 455 MHz in the 5 GHz Band without partitioning
  • We need a Pan European frequency harmonization with final aim for global compatibility as far as possible
