BWA(Broadband Wireless Access)

Objectives for 2004• Draft new Recommendation on Radio

Interfaces for fixed BWA

• Collaboration with participating SDOs: e.g.,– IEEE (802.16 WG): WirelessMAN– ETSI (Project BRAN): HiperMAN

• Liaison with ITU-T SGs 9 & 15

• Support to ITU-D Q.20/2 for preparation of final Report on Broadband

GSC-9, SeoulITU-RITU-R

RLAN(Radio Local Area Network)

Objectives for 2004

• Issues requested by WRC-03

• Protection criteria, if required, for RLANs operating under the provisions of Resolution 229 (WRC-03) (5 GHz band)

• Sharing between RLANs and FWA in Region 3 in the band 5 250-5 350 MHz

• Updating of existing Recs.

GSC-9, SeoulITU-RITU-R

Satellite broadband accessObjectives

• Global broadband satellite systems– Spectrum requirements, frequency bands &

technical/operational characteristics– WRC-07 (§ 1.19): global harmonized spectrum for the

use of Internet applications

• High-density applications in the FSS (HDFSS)– WRC-03: global spectrum (20/30 GHz) & RES143

• Wideband spreading signals• Spectrum above 275 GHz

GSC-9, SeoulITU-RITU-R

ITS (Intelligent Transportation Systems)

Medium-term objectives

• Next generation ITS

• Application sub-layer (ASL) of DSRC

• ITS land mobile applications and technologies in the millimeter waveband

• Vehicle collision avoidance radar at 79 GHz

• ITS sharing in the 5 850-5 925 MHz band

• Handbook

GSC-9, SeoulITU-RITU-R

PPDR(Public Protection & Disaster Relief)

Objectives for 2004• Consideration of WRC-03 results (RES646)

– regionally harmonized spectrum (operators & manufacturers)

• Start work on new Recommendation:– harmonized frequency channel plans for data

comms used for protection of property

• Identification of additional frequency bands:– for certain Region 1 countries

• Update PPDR Report with new technologies

GSC-9, SeoulITU-RITU-R

Health Effects of RF ExposureObjectives for 2004

Electromagnetic fields from terrestrial broadcasting transmitting stations and their vicinity (study Question): calculation & measurement procedures, & design precautions to prevent hazardous exposure of human beings

Spectrum Management (SM) Spectrum Management (SM) Objectives

• Allocations 250-3 000 GHz (Res. 950(WRC-03)WRC-10)• Allocations > 3 000 GHz(optical free-space comms.)

• Improve international SM framework (Res. 951(WRC-03))• Convergence fixed/mobile broadcasting interactive multimedia (Rec. 951(WRC-03) WRC-10)

• EMC with Power-line comms. (PLC) & telephone distribution wiring• Short-range devices

• Guidance for national SM• Economic aspects of SM (Rep. SM.2012)
