) Enhancements to the current 802.11 MAC to pro
vide improvements in Security

rrent 802.11 MAC to provide improvements in
security. IEEE 802.11j (Task Group j) Enhanc
ements to the current 802.11 Standard to provide

• Active Task Groups
• IEEE 802.11n (Task Group n)
• Enhancements to the current 802.11 Standard to
  provide improvements in throughput
  
• The goal of Task Group n is to at least triple
  the effective throughput of wireless local area
  networks
  
• (WLANs). The speed objective set in IEEE P802.11n
  will be defined in a different way than in other
  IEEE 802 standards, e.g., IEEE 802.11g(TM). The
  standard will address higher effective throughput
  at the MAC interface, rather than as a signaling
  bit rate in the PHY layer modulation scheme. By
  focusing on the MAC data service access point,
  the objective throughput in the standard should
  more closely match what users see in transferring
  files and other tasks.

• Wireless Next Generation Standing Committee
• The Wireless Next Generation Standing Committee
  is tasked with exploring and considering future
  technologies, architectures, with the goal of
  proposing future projects that provide

• OVERVIEW
• The original version of 802.15.1 was based upon
  portions of the Bluetooth v1.1 Specification. 
  The Bluetooth Special Interest Group (SIG) is in
  the process of finalizing v1.2 of their
  specification.  The purpose of this TG is to
  review the SIG changes and update 802.15.1.
• 802.15.1a will correspond to the changes made in
  the new Bluetooth Spec, but are to retain the
  IEEE-specific information included in the
  original Standard.
• Review of the entire text of the resulting 15.1a
  Draft will be made first by the TG, then the WG. 
  Any discrepancies between v1.2 and 15.1a will be
  resolved by the TG.  Any errors or unclear
  language in v1.2 will be resolved with the
  Bluetooth SIG and one (or both) of the documents
  will be modified appropriately.

IEEE 802.15 Working Group for WPANs
Active Task Groups IEEE 802.15.3a (Task Group
3a) WPAN High Rate Alternative PHY OVERVIEW
The IEEE 802.15 High Rate Alternative PHY Task
Group (TG3a) for Wireless Personal Area Networks
(WPANs) is working to define a project to provide
a higher speed PHY enhancement amendment to
802.15.3 for applications which involve imaging
and multimedia. CURRENT STATUS At the July 20
03 meeting 6 remaining updated PHY proposals were
narrowed by the down-selection procedure to 1
proposal, but that proposal failed to receive the
required 75 confirmation vote at the Working
Group level. At the September 2003 meeting in Sin
gapore, a process was defined to review the two
most popular proposals, reconcile questions
regarding their respective merits, and prepare
for another down-selection vote at the November
2003 plenary.

OVERVIEW The IEEE 802.15 Low Rate Alternative P
HY Study Group (SG4a) for Wireless Personal Area
Networks (WPANs) is working to define a project
for an amendment to 802.15.4 for an alternative
PHY. CURRENT STATUS To date, the principle in
terest has been in providing high precision
location capability and high aggregate
throughput, as well as adding scalability to data
rates, range, power consumption, and cost. These
additional capabilities over the existing
802.15.4 standard are expected to enable
significant new applications and market
opportunities.

IEEE 802.18 Radio Regulatory Technical Advisory
Group http//ieee802.org/Regulatory/ Summary o
f Charter IEEE 802, the LAN/MAN Standards Commi
ttee (LMSC) currently has 4 Working Groups with
projects on standards for radio-based systems ...
802.11 (WLAN), 802.15 (WPAN), 802.16 (WMAN), and
802.20 (Wireless Mobility). Therefore, monitoring
of, and active participation in, ongoing radio
regulatory activities, at both the national,
regional, and international levels, are an
important part of the LMSC's work. That is the
job of the 802.18 Radio Regulatory Technical
Advisory Group ("RR-TAG"). IEEE 802.19 Coexist
ence Technical Advisory Group http//ieee802.org/
19/ Summary of Charter The IEEE 802.19 Coexi
stence Technical Advisory Group (TAG) will
develop and maintain policies defining the
responsibilities of IEEE 802 standards developers
to address issues of coexistence with existing
standards and other standards under development.
It will also, when required, offer assessments to
the IEEE 802 Executive Committee regarding the
degree to which standards developers have
conformed to those conventions. The Coexistence
TAG may also develop coexistence documentation of
interest to the technical community outside of
IEEE 802.

• Why are open industry consensus standards
  important?
  
• Standards provide many benefits to users
• Availability of interoperable equipment from
  multiple vendors
  
• Prevents a Tower of Babel situation
• Equipment from different vendors will
  interoperate if it complies with the standard
  
• Certification bodies exist to assure
  interoperability
  
• e.g., the Wi-Fi Alliance certifies equipment
  that complies with the IEEE 802.11 Standards
  
• Lowers costs to consumers
• Both through competition and economies of scale
• Promotes the continual advancement of
  technology
  
• Vendors constantly strive for competitive
  advantage through improved technology and features

21

• How can regulators assure that their citizens
  receive these benefits?
  
• Make sufficient spectrum available for these
  applications
  
• Adopt a Licensed by Rule or Class License
  paradigm as appropriate
  
• Individual licenses are totally impractical for
  many applications
  
• Applications like WLANs are different from,
  e.g., cellular systems
  
• Systems are owned and operated by many users
  (100s of ks, millions)
  
• Distributed, not centralized, ownership and
  operation
  
• Individual licensing burdensome for both users
  and regulators
  
• Allow sale and use of equipment certified to
  comply with minimal technical parameters
  necessary to assure that devices will not cause
  unacceptable risk of interference to other
  services
• Refrain from auctioning spectrum for these
  applications
  
• Spectrum auctions are also impractical for many
  applications
  
• Systems are owned and operated by many users
• Distributed, not centralized, ownership and
  operation
  
• Unlike, e.g., cellular, no single owner/group to
  buy spectrum
  
• Value to society far greater than value of
  potential auction revenues
  
• Low cost of ownership, increased productivity,
  access to internet economy
