2. GSC-9, Seoul ETSI BRAN Interoperable Standards PHY DLC CL Testing ETSI BRAN (Broadband Radio Access Networks) HiperLan/2 (High Performance LAN) Wireless LAN at 5 GHz, connection-based, OFDM, 54 Mbps, QoS HiperAccess (High Performance Access) Fixed broadband wireless PMP system above 11 GHz, single carrier, 120 Mbps HiperMan (High Performance MAN) Fixed broadband wireless PMP system below 11 GHz, OFDM, IP-optimized PHY DLC CL etc. PHY DLC Profiles MIB Regulatory Competence Group Testing

3. GSC-9, Seoul ETSI BRAN and IEEE 802.16 Standards ETSI BRAN HiperAccess ETSI BRAN HiperMAN IEEE 802.16 WirelessMAN-SC IEEE 802.16 WirelessMAN-OFDM above 11 GHz (single carrier) same PHY layer further harmonization below 11 GHz (OFDM) same PHY layer same DLC layer different PICS,... additional modes for IEEE same „generic“ DLC layer

4. GSC-9, Seoul 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)

5. 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 Overview: HiperAccess and HiperMAN

6. GSC-9, Seoul613/08/2015 HiperAccess Main 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

7. GSC-9, Seoul HiperMAN Main 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)

8. GSC-9, Seoul Requirement Interoperability Spectral efficiency High QoS Low cost design Future proof 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 part option for TDD, support of H-FDD. Several further options, „hooks“ for future evolution, phased roll-out: 1st ATM, 2nd IP
