RADIOCOMMUNICATIONS AGENCY Annette Henley Private Business Systems Unit (PBSU) Spectrum Issues for developments of WHANs at 5GHz
Structure of the presentation UK 5GHz Consultation Exercise Spectrum Available For HIPERLAN Process So Far WHAN in 5GHz WHAN Sharing Issues problem areas RA policy on Sharing Issues
5GHz Consultation Exercise 5150-5350MHz allocated to HIPERLAN max. EIRP 200mW indoor use only 5470-5725MHz allocated to HIPERLAN max. EIRP 1W 5725-5875MHz ISM band also allocated to short range devices max. EIRP 25mW The bands being consulted on are: HIPERLAN = HIgh PERformance Local Area Networks
5GHz Consultation Exercise What is the Consultation About? The Agency believes that the direction of development should be driven by needs of the market in terms of cost, required service and accessibility of the technology concerned. In particular the Agency was seeking views on:- –whether only interoperable systems should be permitted to use the spectrum or whether other systems, only capable of co-existence, should also be allowed in; –whether only private systems should be permitted or whether public systems should also be allowed; –determining the best way to allocate the available spectrum.
5GHz Consultation Exercise Process So Far 1st Round asked for written responses to the Agency Consultation Document on Short Range, High Data Rate, Nomadic Equipment Operating in the Frequency Range 5.150 - 5.875 GHz (Issued October 1999) Analysis of the Responses Received and Drafting of RA Strawman Proposal for presentation at 5GHz Consultation Event 2nd Round SMAG 5GHz Consultation Event – (2 June 2000) Set up UK 5 GHz Advisory Group - 1st meeting held 27th July 2000
1st Round Responses 21 individuals and organisations replied –Ericsson –RadioLAN –Internet Central –IEEE 802.11 –TTP –Central Research Laboratories –Nokia –Philips –Motorola –Philips –Motorola –Sky –Lucent –BBC –Media Channel –Norweb –Francis Walker –HIPERLAN 2 Global Forum –Professor Stephen Barton, University of Manchester –BT –Orange –Adaptive Broadband –Logica See Website:www.radio.gov.uk
Analysis From 1st Round HIPERLAN Type 1 and HIPERLAN Type 2 cannot co-exist in the same location HIPERLAN Type 2 and IEEE 802.11a use same channel raster. 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.
2nd Round Strawman Proposal 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 5470-5570 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
Terms Of Reference for 5GHz Advisory Group To produce recommendations to the RA which will: ‘Set the regulatory framework to ensure early access to the 5GHz sub-bands, maximising the optimal usage of the available spectrum and ensuring harmonisation with both European and International regulations. The framework will also recommend where necessary the appropriate standards to which equipment will be required to conform’.

WHAN Sharing Issues in 5GHz How many of the previous applications are compatible with or are part of WHAN systems? What is the spectrum requirement for WHAN? Will all WHANs be using equipment that can co-exist or is interoperable? How will Public Access systems be licensed? How will other co-primary users effect the available spectrum for WHAN?
WHAN Sharing Issues in 5GHz Band partitioning is the key issue. – The consultation results showed that the there is very high demand for the usage of the 5GHz spectrum for a number of different applications. WHANs are probably going to have the largest spectrum requirement. – The consultation covers a huge tranche of spectrum (455MHz HIPERLAN plus 150 MHz ISM). How much of that spectrum can be used without any partitioning is the key issue for WHANs.
WHAN Sharing Issues in 5GHz – 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 (e.g. public services). – If all the equipment used in the band can, at the very least, co-exist then the need to partition on the basis of equipment types is alleviated.
WHAN Sharing Issues in 5GHz – The spectrum requirement for WHANs will be determined by the highest data rate device that the WHAN has to interface. – The spectrum available for WHAN will be affected by the number of co-primary services that are being operated in the UK. (i.e. EESS, MSS)
RA policy on Sharing Issues RA actively supports ongoing work looking at spectrum requirements within the UK DTG WHN group and the DVB commercial requirements group. RA to encourage the development of highly spectrum efficient equipment for use within the home environment by using suitable coding techniques e.g MPEG. RA, OFTEL and CII are consulting at present on the provision of Public Services within licence exempt spectrum.
RA policy on Sharing Issues RA currently attends ETSI BRAN and IEEE 802.11a to support work towards one world wide generic 5GHz standard. RA signed up to ERC decision 99-23 on HIPERLAN and is participating in ITU studies looking at the sharing issues in 5GHz with a view to having a mobile allocation confirmed at WARC 2003.
