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

Overview HiperAccess and HiperMAN

• 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)

• Requirement
• Interoperability
• Spectral efficiency
• High QoS
• Low cost design
• Future proof

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 part option for TDD, support
of H-FDD. Several further options, hooks for
future evolution, phased roll-out 1st ATM, 2nd
IP
