Core Networks: ATM, IP, ISDN, PSTN,...

Removes differences between core networks

Matched to the requirements for supporting ATM and IP

Ensure cost-effective implementation and spectral efficiency

DLC and PHY layers are independent of the core network

Interworking Approach (shown for HiperAccess, similar for all BRAN systems)

GSC-9, Seoul

• Point-to-Multipoint (PMP) topology

• Interoperability (testing is normative part of standard)

• Standard allows for vendor-differentiated products, e.g., - management, - core network interfaces, - ARQ, - broad range of cellular constellations - security, - bandwidth allocation strategies, ...

• Spectrum efficient (both for IP and ATM core networks)

• Dramatic improvements compared to 1G/proprietary systems

HiperAccessMain Characteristics

• Main applications:

– UMTS backhauling, SOHO, SME

– optimized for ATM and Ethernet

• ETSI BRAN developed protocol stack and radio specifications

• Supporters and interest from:

– Manufacturers: Alcatel, Ensemble, Ericsson, Marconi, Nokia, Siemens, etc.

– Operators: France Telecom, Omnitel Vodafone, Sonera, Telecom Italia, Telekom Austria, Telenor, Telia, etc.

• Strong points

– Suitable for immediate deployment in 2G and 3G networks

– Technical quality• Precision of specification• Well controlled optional features • Absence of ambiguities• Test specifications with ETSI strength

HiperMANMain Characteristics

• Main applications– SOHO, SME (wireless DSL)– Mesh radio networks (radio based routers)

• Based on IEEE protocol stack (IEEE802.16)– Profiling 802.16 to a narrower set of options– Adding things that 802.16 is now embracing

• Strong points– Developing in parallel with IEEE802.16– Industry forum WIMAX that is backing IEEE802.16 but is

present in HiperMAN as well– Test specifications with ETSI strength (ongoing)

Conclusions for HiperAccess (and HiperMAN)

Solution

A small number of well-controlled options, ASN.1-based message encoding,detailed test specifications.

Adaptive modulation & coding,adaptive power control.

Centralized radio link control,centralized scheduling,robust messaging.

Large network-independent partoption for TDD, support of H-FDD.

Several further options,„hooks“ for future evolution,phased roll-out: 1st ATM, 2nd IP
