Introduction
• IEEE 802.20 is a new standard for mobile broadbandwireless access.
• IEEE 802.20 was developed by the Mobile BroadbandWireless Access (MBWA) Working Group andsponsored by the IEEE 802 Local and MetropolitanArea Networks Standards Committee.

History
• Published in August 2008
• Liaison relationship with ARIB
– ARIB (Association of Radio Industries and
Business) of JAPAN adopted and standardized
802.20 for Japan application.

Mission
• Efficient & packet-based air interface optimized for IP-
based services
• Affordable, ubiquitous, always-on, and interoperable
mobile broadband wireless access
![Page 5: Mobile Broadband Wireless Access](https://reader036.fdocuments.in/reader036/viewer/2022081804/55a7a21f1a28ab4d438b48ab/html5/thumbnails/5.jpg)
Scope
• To define the PHY and MAC layers
• Optimized for IP-data transport, with peak data
rates larger than 1 Mb/s per user
• Supports various vehicular mobility

802.20
• IEEE 802.20 will fill the gap between cellular networks
and other wireless networks
• Different from 802.11(WLAN) and 802.16(WiMAX)
• It will increase coverage or mobility
• Defines Medium Access Control (MAC) protocols
with several different physical (PHY) layer
specifications

Technical Aspects
• Peak user data rate
• Peak aggregate data rate
• Spectral efficiency
• Bandwidth
• Maximum operating frequency

System Aspects
• The 802.20 standard intends to permit either a fixed
hierarchical network or non-hierarchical network.
• The specification structure provides a versatile
framework that can easily accommodate future services
and capabilities while not compromising QoS.

Application Support
• It shall support applications such as video, web
browsing with graphical capability, e-mail, file
uploading and downloading without size, streaming
video and audio, Voice-Over-Internet Protocol (VoIP),
instant messaging, and all while maintaining an
always-on connection.

Security
• Includes three major factors protecting against theft,
privacy of the user, denial-of-service attacks.
• AES is the encryption algorithm is used to provide
security.
• Providing authentication to mobile station and base
station.

IEEE Std 802.20.2
• IEEE Standard for Conformance to IEEE 802.20
Systems-Protocol Implementation Conformance
Statement (PICS)
– This standard represents the Protocol
Implementation Conformance Statement for
conformance specification of access nodes and
access terminals based on the air interface specified
in IEEE Std 802.20.
![Page 13: Mobile Broadband Wireless Access](https://reader036.fdocuments.in/reader036/viewer/2022081804/55a7a21f1a28ab4d438b48ab/html5/thumbnails/13.jpg)
IEEE Std 802.20.3
• IEEE Standard for Minimum Performance
Characteristics of IEEE 802.20 Terminals and Base
Stations/Access Nodes
– This standard specifies minimum performance
parameters and the associated test methodologies
for implementation of IEEE 802.20 compliant
systems.

IEEE Std 802.20a
• Management Information Base Enhancements and
Corrigenda Items
– This enhances IEEE 802.20 Management
Information Base (MIB). This also corrects any
errors, inconsistencies, and ambiguities associated
with the MIB clause of IEEE Std 802.20

IEEE Std 802.20b
• Bridging of IEEE 802.20
– This specifies the mechanism for the support of
bridging of IEEE 802.20 networks.

Summary
• The IEEE 802.20 Standard provides highly optimized
solutions.
• Significantly higher performance and flexibility than
competing technologies.
• Optimized mobility and advanced QoS mechanism will
enhance user experience and provide leading edge
performance.
• Service providers will benefit from the use of flexible
mechanism to deliver and differentiate their services.
• An implementable standard for commercial and
consumer application.
