5GHz Consultation The RA asked 5 questions in the consultation Is there a case for HIPERLAN Type 0? based only on simple radio parameters? If HIPERLAN Type 0 is not adopted by ETSI is there a case for the UK to introduce such a standard on a UK only basis? What are the likely applications for these bands, what development issues remain unresolved, and when and how will services be introduced? Is there a requirement for public access systems in these bands, what kind of systems would be envisaged and how should they be regulated? How best should these bands be assigned, given the aim of frequency assignment is to ensure that the maximum numbers of users get appropriate and fair access to spectrum for their applications?

Initial Analysis HIPERLAN Type 1 and HIPERLAN Type 2 cannot co-exist in the same location HIPERLAN Type 2 and IEEE 802.11a can There is a lobby for partitioning on HIPERLAN Type 1 and HIPERLAN Type 2 basis and on a public/private basis Some requirement for co-ordinated spectrum as well as licence exempt operation has been demonstrated There appears to be more demand for access to public and semi-public spectrum than for private only applications The number of users for particular applications is still an unknown quantity. The high volume markets for RLAN equipment will be significant.
Applications 5GHz technology Conference & classroom / lecture theatre scenarios Public access to high speed data networks Portable videoInteractive museum guides Dispersing an incoming broadcast signal around the home high speed data off and home applications Short range links in transport environments such as railway platforms Vehicle to vehicle linksHot spot access for travelling business people at locations - airports, hotels & conference centres Infotainment
RA Proposals IEEE 802.11a be permitted to operate in these bands HIPERLAN 0 versus acceptance of IEEE 802.11a should be investigated further. The bands should be partitioned according to the following bands ……...
RA Proposals 5150-5250 MHz HIPERLAN Type 1 for indoor systems only, licence exempt. Max EIRP 200mW. This use reviewed after 2 years 5250-5350 MHz HIPERLAN Type 2/IEEE 802.11a, for indoor systems only, licence exempt. Max EIRP 200mW 5470-5550 MHz HIPERLAN Type 2/IEEE 802.11a, licence exempt. Outdoor and indoor systems. Max EIRP 1W 5570-5725 MHz HIPERLAN Type 2/IEEE 802.11a, for systems on a licensed basis. Outdoor and indoor systems. Max EIRP 1W 5725-5875 MHz Low power devices, licence exempt. Max EIRP 25mW Band Use
RA Proposals If there is a requirement for public networks, then that service should be regulated by licensing. If some of the band is to be used by smaller, local services, should there be a low cost, easy entry to the spectrum?
RA Proposals Public Access Systems in this band be further regulated to enhance / enable small regional ISPs and or other local and community services to gain access to the spectrum Widespread, licence exempt and comprehensive access for private networks should be retained
RA Proposals - Notes The consultation results showed that the majority of respondents were in favour. This consultation covers a huge tranche of spectrum (455MHz HIPERLAN plus 150 MHz ISM) and some partition must be inevitable. Licence exempt uncoordinated spectrum use has advantages to certain types of users but is not the best use of spectrum for services requiring guaranteed quality of service levels Band partitioning is the key issue.
RA Proposals - Notes Only 5150-5250 MHz has currently been agreed by footnote in the Radio Regulation as an allocation to the mobile services by the ITU-R. The ERC Decision has allocated the other parts of the band within Europe only.
