Group3 Standards: H2 vs other standards

Group3 Standards H/2 vs other standards?

• What the future for HIPERLAN type 1?
• Hiperlan 1 not suitable for an operator to give
  public access.
• Not many vendors are today designing HIPERLAN
  Type 1 systems or chipsets
• Bluetooth seems to have taken part of services
  intended by HIPERLAN/1.
• Could be used in the lower part of the band
  indoors only, specific applications.
• No exclusive band for H/1, share lower part with
  H/2. Market decides which system to win.
• Within a 2 year period H/1 must change the
  specification to follow the ERC decision.
• Should IEEE 802.11a be permitted in UK and
  Europe?
• You should not prevent the use of IEEE 802.11a in
  Europe. Under the new RTTE directive it seems
  very difficult to prevent IEEE 802.11a products
  since the physical layers are already harmonised.
• IEEE 802.11a must implement DFS and TPC to fulfil
  ERC decision. The necessary changes in the MAC
  are already being considered.

• Many vendors are implementing the IEEE 802.11a
  products.
• Co-ordination between ERC and IEEE is needed to
  verify the ERC requirements.
• With or without complying to the ERC decision?
• UK and other european countries should comply
  with ERC.
• What restrictions should apply?
• The ERC decision should apply.
• A harmonised channel raster like the 20 MHz
  channels used by H/2, IEEE and MMAC should be
  required. Note that this is already a requirement
  in Japan.
