Conclusions
Wireless Infrastructure
Wireless communication no longer means mobile
Plain Old Telephone Service
Integration of media and services
IP based control protocols are much better than the
combination of circuit and packet technologies in use
today.
SIP (Session Initiation Protocol)- IP based
multimedia services
Broadband technology is needed to provide
foundation for future Wireless multi-media networks

802.16 Future Areas
IEEE 802.16e
Will allow seamless handoffs between base
stations.
Providing true mobile broadband connectivity.
Development needed to 802.16 protocol.
Aims basically at throughput than mobility.
802.20 is developed to cover the mobility part of
the 802.16.
802.20 Mobile Broadband Wireless
Access: Mobile-Fi
Broadband on the Run (up to 250 km/hr, 155mph)
Standard Air Interface for Mobile Broadband
Wireless Access Systems Supporting Vehicular
Mobility - Physical and Media Access Control Layer
Still being developed
Led by companies such as Flarion Technologies and
ArrayComm
802.20
The IEEE 802.20 standard should form the basis for
systems that support seamless integration of the three
user domains - work, home, and mobile, with various
scenarios.
The 802.20-based air-interface (AI) shall be
optimized for high-speed IP-based wireless data
services.

802.20
How will the standard operate?
Flarion plans to support 802.20 MBWA using
Orthogonal Frequency Division Multiplexing
(OFDM). This multiplexing technology divides a
single high-speed channel into multiple parallel lowspeed channels that do not overlap. (1)
Motorola Proves 300Mbps possible using OFDM (2)
802.20
Will operate in licensed bands between 500 MHz and
3.5 GHz.
Ranges of up to 15 kilometers (km) are likely at peak
data rates of 1 Mbit/s per user.
PC card interface with devices must be used.

broadband data network for police and fire in
Washington DC(5)
No full scale deployment to consumers at this time
Who will be Using 802.20
Every industry tends to gain from mobile broadband,
but an immediate need exists in industries that
employ large sales forces such as insurance,
pharmaceuticals/health care and real estate. (5)
Wireless broadband benefits will not be realized
unless a LAN-like experience in the wide area
environment is offered. (5)
802.20 Market Analysis
By 2006, 46% of American Households will have
broadband connections.
The dramatic uptake of cable and DSL shows that for
wireless data to succeed, the same attributes must be
offered:
Broadband speeds (1-1.5 Mbps typical user
experience)
Low latency (less than 50 ms)
Similar pricing
(6)
802.20 Market Analysis
Companies will be able to reduce some of the
overhead and operational costs associated with large,
centralized headquarters and call centers, as well as
costs associated with travel and remote access to the
Internet and corporate LAN. (5)
The 9-11 Commission recommends a national
wireless high speed public safety network. (7)
802.20 Market Analysis
Applications intended for low latency, QoS and
broadband speed
Internet Gaming: smooth, predictable controls, timely
feedback
Internet messaging: keeps flow of conversation insync
VoIP: natural pace of conversation, no strained
waiting
Video Conferencing: less dropped frames = less jitter
802.20 Market Analysis
Main selling point of 802.20
mobility
problem:
The majority of Americans
prefer to drive their own
car.
How will they benefit
from mobile internet
connection?

Is 802.20 All Hype?
Conclusion
Provides the user an “Always-On” experience
802.20 also supports broadcast/multicast
Not yet launched into the market
If there's success in the 802.16 market, it will
definitely mean good things for the 802.20 market
802.20 maybe a direct competitor to third-generation
(3G) wireless cellular technologies.
