Re: MBWA Call for Contributions
Abstract To be successful, 802.20 must provide higher performance than existing alternatives. Existing systems and techniques we can incorporate into the standard to achieve high performance will be discussed.
Purpose To facilitate discussion of the 802.20 requirements document.
Notice This document has been prepared to assist the IEEE 802.20 Working Group. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.
Release The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.20.
Patent Policy
The contributor is familiar with IEEE patent policy, as outlined in Section 6.3 of the IEEE-SA Standards Board Operations Manual <http://standards.ieee.org/guides/opman/sect6.html#6.3> and in Understanding Patent Issues During IEEE Standards Development <http://standards.ieee.org/board/pat/guide.html>.

The Most Effective Requirements...
….Are simply stated
Emperor Nero, to his banquet entertainers
“Astonish me”
President Kennedy, to NASA
“A man on the moon by the end of the decade”
Goal for 802.20
To be the technology of choice for mobile data
to achieve this, we must:
• Go beyond what 3G or 3G enhanced can do
– Higher in data rate
– Better in dealing with high-speed mobility
– Simpler in interfacing with IP land-line networks
– Faster in handoff
• Also, be better than 802.16e
Otherwise, why bother?
• Assuming that our next-generation system will be better than the competition
– Just because it’s better than their last one– They are working on their next generation, too
• To succeed, we need to be have higher throughput than existing systems
– And higher than their next (enhanced) version
Consider ATM vs. Ethernet: 25 & 155 Mbps vs. 10 Mbps--Ethernet moved to 100 Mbps and wiped out premises ATM
The Classic Mistake
The Current State of the Art
We need to beat these numbers by a significant margin:
TD-CDMA (Rel. '99 in 5 MHz) FWD REVPeak rate (no split) 4.5 - MbpsPeak rate (9:3 TDD split) ~3.4 ~1.1 MbpsAvg throughput ~1.5 ~0.9 Mbps
TD-CDMA (Rel. 5 in 5 MHz) FWD REVSector throughput ~1.9 Mbps
EVDO FWD REVPeak 2.4 0.153 MbpsThroughput 0.7 MbpsThroughput @ 3 km/h, 1 Rayleigh path 1.2 Mbps
Enhanced DO (proposed) FWD REVPeak ~3 ~1.2 Mbps
S-CDMA (in 5 MHz)Peak rate 2.1 1.0 Mbps
IEEE 802.16a (non-mobile in 20 MHz)Peak (3:1 TDD split) 60 10 Mbps
What is our Sustainable Technical Edge?
• Packets?– Most new systems use packets
• More complex modulation ?– All current systems have discovered the laws of physics
• CDMA?– 2G, 2.5G, and 3G have CDMA
• OFDM?– 802.16a has that
• Narrow channels to fit existing allocations?– New spectrum is unlikely to require narrow channels
• Maybe it’s complex antennas– 802.16 and even 802.11 are thinking about smart antennas
• Maybe it’s our simple IP-based protocol stack– Nothing prevents 802.16 from using the same stack
Bottom line: if there is no single “killer” advantage, then we have to tune our system better. The devil is in the details.
The Tools We Have
• Simple protocol stack– Conformance to normal data practice– Voice and video support via QoS scheduling
• Smart antennas– Great improvements in rate are possible– But the competition can add this to existing standards
• Targeted primarily at mobile users– Not an add-on– Power consumption considered from the start
• Consistency across different channel sizes– Easy roaming for the user and system migration for the operator
• Adaptive modulation and coding– Optimize for varying signal strength and different multipath environments
• Smart scheduling– Predict user’s nulls and avoid them– Identify user clustering
