1 MPTSWG(02)20 Original HIPERACCESS Scope n FWA radio access >25Mbit/s n Interoperable products n Focus on mass market n Symmetric or asymmetric traffic n Optimised for ATM n Competing with fibre, xDSL and cable modems

2 MPTSWG(02)20 Main Features n P-MP Topology n Single carrier n Adaptive coding and modulation n Adaptive power control n Supports different duplex schemes n Nominal cell size 43.5 GHz with % availability in rain zone K

3 MPTSWG(02)20 Frequency Bands n Focus on – GHz – GHz n Other bands of interest – GHz – GHz – GHz (TDD) – GHz

4 MPTSWG(02)20 Duplex Schemes n Frequency Division Duplex (FDD) –separate channels for uplink and downlink n Half-FDD (H-FDD) –In the Access Terminal (AT) only to facilitate cost reduction due to relaxation in isolation n Time Division Duplex (TDD) –Both AT and Access Point (AP) are half-duplex - utilise one channel

5 MPTSWG(02)20 Multiple Access Schemes n AP downlink –TDM contains data for full-duplex ATs or ATs are scheduled to transmit later in the frame than they receive –TDMA - optional contains data for half-duplex ATs n AT Uplink –TDMA

6 MPTSWG(02)20 Channel size, bit rate, modulation & coding n Channel size 28 MHz n Downlink –4, 16 and optionally 64 QAM n Uplink –4 and optionally 16 QAM n Concatenated Reed-Solomon with inner conventional code in some cases n Modulation and coding combinations form PHY modes

7 MPTSWG(02)20 Services n Both QoS and best effort supported n Internet Access n Telephony and video conferencing n Back-haul n Remote LAN

8 MPTSWG(02)20 HIPERACCESS Standards (www.etsi.org) n Requirements and Architectures TR –Published May 1998 n System Overview TR –Published March 2002 n PHY protocol specification TS –Published April 2002 n DLC protocol specification TS –Published September 2002 n Radio conformance test specification TS –Publication scheduled by end 2003 n Cell based convergence layers TS –Part 1 published Sept ‘02 & part 2 published Oct ‘02 n Packet based convergence layers TS –Part 1 published Sept ‘02 & part 2 published Oct ‘02 n Conformance test specifications - ongoing
