When is it expected?

What are the expected connection speeds and ranges?

Who are the leading researchers?

Due to the lack of response to date, I have decided to DELETE the
aspect of the question that asks "Who are the leading researchers?".

Hi! Thanks for the question.


According to Intel, the next generation of wireless technology that
has to go beyond Wimax will be 802.20.

?The next generation of mobile connectivity beyond WiMAX will be based
on the pending 802.20 standard, which is being developed from the
ground up as a mobile specification.?

?The 802.20 specification is also the first IEEE standard that
explicitly addresses the needs of mobile clients in moving vehicles.
The design parameters of the specification include support for
vehicular mobility up to 155 miles per hour. This criterion will
support use in fleet cars and trucks, as well as in the high-speed
commuter trains in use throughout much of the world.?

?802.20 Targets Fully Mobile Broadband Wireless?
http://www.intel.com/cd/ids/developer/asmo-na/eng/strategy/95510.htm?page=3 


------------------------------
802.2 speeds are predicted to rival that of DSL and Cable broadband technologies.

?The 802.20 interface seeks to boost real-time data transmission rates
in wireless metropolitan area networks to speeds that rival DSL and
cable connections (1Mbps or more) based on cell ranges of up to 15
kilometers or more, and it plans to deliver those rates to mobile
users even when they are traveling at speeds up to 250 kilometers per
hour (155 miles per hour). This would make 802.20 an option for
deployment in high-speed trains. The 802.16e project authorization
request specifies only that it will "support subscriber stations
moving at vehicular speeds"; Kiernan said the group has achieved
speeds of 120 to 150 kilometers per hour (75 to 93 miles per hour) in
simulations.?

?Formally known as "The Standard Air Interface for Mobile Broadband
Wireless Access Systems Supporting Vehicular Mobility - Physical and
Media Access Control Layer Specification," 802.20 would support
transmission speeds of up to 1M bit/sec in the 3-GHz spectrum band.?

?Exactly how the standard will operate is still open to debate.
Flarion plans to submit a plan to support 802.20 MBWA using Orthogonal
Frequency Division Multiplexing (OFDM).?

RESEARCH:

Big name telecommunication companies are members IEEE Working Group
for 802.20. They are the ones pioneering the research tests and
implementation.

?In March 2002, the notion of 802.20 was launched with a tutorial
presented by Cisco, Flarion, HP (Compaq) and Nextel. This act formed
the basis for the IEEE MBWA Study Group, whose purpose was to carry
out a feasibility analysis and develop the project-authorization
request that would lead to the formation of a full-fledged standards
working group within IEEE. Through multilateral efforts and
contributions from across the industry, including ArrayComm, Flarion,
Motorola and Nextel, the study group reached a consensus and was
sanctioned as the 802.20 Working Group by the IEEE Standards
Association Board last December.?

In fact there were reports that Nextel has already planned limited
tests of 802.20 technology to its customers.

?The wireless operator started soliciting both businesses and
consumers in the Raleigh-Durham, N.C., area to participate in trials
for its Nextel Wireless Broadband. The trials will start in February
and will last as long as six months, the company said at its Web
site.?

In the Wi-Fi planet article it mentions something along the lines that
802.20  was actually  proposed as alternative to the mobile version of
WI-MAX.

I don't see 802.20 being more than 12-18 months away. What I was
looking for is something that is 5 years away. I should have been more
specific. Do you have any clues that far out as the likely connection
speeds etc.

Hi visionisity-ga!

I was only looking at your immediate question which is what may come
beyond Wi-Max. Since we researchers can only answer based on the
parameters of the original question I responded to the original
inquiry above.  The time frame for the upcoming technology wasn't
included since it was not in the original question.

However, I also considered looking for technology, years beyond but
cannot find anything substantial. Since Intel foresees 802.20 is the
technology to look up to after Wi-Max and significant research and
testing is already being done then this is possibly the next wireless
sensation out there.

I hope you understand.

Thanks again.

It's the X2-NBY.

Expect it soon but please don't expect any researchers.

It's just a marketing gimmick.
