11. PacketMAX Performance – Latency
Latency is as important as net throughput:
Impacts TCP performance
Necessary for VoIP services
Necessary for TDM emulation (e.g. E1 over WiMAX)
As for throughput, latency depends on system configuration
Service classes: CBR uses UGS for low jitter; CIR w/ rtPS for non constant bit rate
Frame parameters: the shorter the frame, the lower the latency and throughput
Up to more than 60 Mbps per channel with 20 MHz channels
ARQ impacts latency and jitter – if application tolerates BER, it can be turned off
PacketMax allows a flexible configuration of all parameters and QoS attributes
Example:
2.5 ms frames, 50/50 UL/DL
CBR (UGS)
CIR (rtPS)

802.16e Products
Most of the systems available today are first generation systems, using mostly proprietary solutions based on older technologies (802.11, CDMA, etc.). As we have seen in previous slides, these systems are severely limited and cannot offer carrier class services.
A new breed of systems have seen the light a few years ago: while still using proprietary technologies, they offer most of the features and performance of Aperto is the first one to have introduced class technology to the BWA market, with our first PacketWave system in New systems are being introduced, including some aspects of the standard (for example OFDM 256 modulation). Although they offer basically the same performance as standard compliant systems, they will not be interoperable (in the absence of a final WiMAX interoperability specification). Note that interoperability is a prerequisite for achieving economies of scale (allowing for example consumer electronic companies to enter the CPE market without having to build base stations). Nevertheless, availability of class systems makes it possible for operators to realize a profitable business case today by offering a cost-effective carrier-class platform and to offer services to a wide array of users from the SME to the SOHO or the WiFi backhaul market.
True WiMAX certified systems are expected to see the day in late 2004, or more realistically in Note that typically it takes 24 to 36 months after a standard is published before a standard compliant product becomes widely available.
Possible questions:
- when will Aperto have the Standard Compliant version?
 Aperto is looking into various options with different chip vendors. Our goal is to reach the market with a complete carrier-class solution in the best time possible
The typical development cycle for standard-based and interoperable systems is by nature long and convoluted. First a group of experts has to agree on requirements and then a common technological approach and platform. This is what did in 2000/2001, selecting burst mode TDMA as the “heart” of Several options have been left open: duplexing scheme, modulations, ARQ, etc. Following that agreement, experts have to design a system-level specification to guide implementers in all companies according to a common blueprint. The resulting specification is the first iteration of the standard (802.16a having been published in early 2003).
It is however only that phase that implementers typically start working on the details of the protocols, chip designs and software (although in the case of Aperto, that effort has been conducted in parallel to the standard development process and has resulted in today’s PacketWave product). During the development process, engineers will find inconsistencies or open options in the standard which they will have to refer to the standards group to obtain a clarification. It is very important that these issues be documented in the standard since they could impair interoperability. This process is typically a long one – as an example, it took 35 revisions of the initial GSM standard before interoperability was finally possible (and that is not counting any new features that were introduced later on). In the case of , this process has barely started. While common implementation at the PHY layer will be simplified by using common chips (e.g. Intel, Fujitsu, etc.), MAC implementation will require a longer time as each system developer learn about this technology and agree on a common platform.
