Q:
What's 4GMF ®? A:
Fourth Generation Mobile Forum
®. |
Q:
What's the objective and mission of 4GMF?
A: To setup an industrial alliance in
proposing and defining the 4G mobile
communication standards for the US, China markets as
well as other emerging markets in the
Asia-Pacific regions. |
Q:
Why is this 4GMF so urgent in the region? A:
As OECD report stated, current 3G did not
fundamentally improve the 2G mobile
architecture, and therefore 3G becomes very
limited in further technology development
and is a transitional solution only. 4G can
greatly improve the wireless and mobile
communication architecture, and therefore
US,
China and the regions will definitely focus
on 4G technology in long-run. |
Q:
What's 4G technology? A: 4G will
basically focus on Open Wireless
Architecture (OWA) with cost-effective,
spectrum-efficient high-speed wireless
transmissions (including wireless mobile and
wireless access). In a word, 4G will
converge existing wireless technologies into
an open platform so that the individual
wireless modules are extensible and
upgradeable, and can be from different
vendors. |
Q:
Why is it very beneficial for the mobile
users? A: With this new 4G technology,
users can integrate their mobile phone,
wireless access equipment, office phone,
home phone, etc into ONE single personal
communicator (personal phone) with ONE
personal communication number. |
Q:
Why is 4G very critical in terms of spectrum
utilization? A: 4G supports dynamic
spectrum access and recycling technologies
which is very important to improve the
spectrum utilization. Current 3G and 2G use
static spectrum allocations, and waste huge
spectrums in the commercial bands. Without
this 4G improvements, all mobile phones will
be shut-off by year 2030 due to
unavailability of wireless spectrum. |
Q:
What's the elements of future 4G radio? A:
The future 4G radio is first, a computer,
then an Open Wireless Architecture (OWA)
terminal. |
Q:
Should 4G mobile focus on high-speed
wireless transmission (for example, 100Mbps
or 1Gbps) only? A: Definitely Not! 4G
mobile should focus on Open Wireless
Architecture (OWA) rather than high-speed
wireless transmission only, both from
theoretical and practical studies. The later
should be limited to Broadband Wireless
Access (BWA) system because we do not have
so much spectrums for mobile communications,
and the mobile spectrum efficiency is
extremely low! |
Q:
Can you provide a simple example of such 4G
systems which we can see the market very
soon? A: A simple example of such 4G-OWA
systems is the "WiFi / WiMax / GSM" 3-in-1
open mobile phone which will be deployed
very soon. The WiFi supports VoWiFi and Data
services. Normally WiFi and WiMax plus
backhauls can support full mobile
communications in the city. In case of
unavailability of such networks, the phone
goes back to GSM mode. By using this 4G-OWA
technology, the spectrum efficiency can be
increased by at least 40%. By year 2010, we
will be able to deliver the commercial GSM /
cdma2000 / TD-SCDMA / WiFi / WiMax /
Bluetooth 6-in-1
single mobile phone based on this 4G-OWA
technology. |
Q:
What's the main subsystems of such 4G
mobile phone? A: RF (Radio Frequency
unit), BB (Base-Band processing unit),
Networks and infrastructure, OS (Operation
Systems unit) and Application/Service
platform unit. |
Q: Are there any companies already
working on such 4G systems? A: Lots
of companies (most are Fortune 500
companies) have already worked on such 4G
technologies, for example, Intel on
converged WiMax/WiFi platform, TI on dynamic
spectrum access, Alcatel on open basestation
architecture, Cisco on open wireless router,
Oracle on open enterprise mobility platform,
Mentor Graphics on open OS platform, Samsung
on open terminal platform, etc. We just need
4GMF to put everything together and make it
an industrial standards. |
Q: What's the timeframe for 4GMF
standards development? A: 4GMF was
launched in March 2007, and the first
version standards will come out before 1Q2010,
so that US and China can launch such initial
4G services by
early 2012. |
Q: Is 4GMF an international standards? A:
Yes! it is registered internationally and
will be a global industry standards of 4G
mobile communications. But the initial
markets will be targeted for US, China
and the A/P regions. |
Q: Do you have enough technical backups
for 4GMF program? A: Yes! we have
five major international 4G & B3G technology
conferences to backup the technology flows
for the 4GMF missions. Every year we receive
thousands of 4G technical submissions
worldwide to support the technology
development for the 4GMF technical
activities. |
Q: Is 4GMF a governmental platform?
A: No! 4GMF is a non-governmental
standardization program. 4GMF is an
independently operated standardization and
technology-development organization,
supported by sponsors, partners, endorsers
and members across the global. |
Q: Who will be involved in 4GMF
standardization activities? A: Both
local and international vendors,
operators, providers, investors,
policy-makers and research bodies, etc will
be involved in this important
standardization process. |
Q: Will the 4GMF results be submitted to
ITU? A: Not necessary ! 4GMF is an
industrial standard starting from
Asia-Pacific
markets. ITU only regulates spectrum
allocation policy and issues recommendations
only for global mobile communications. ITU
never publishes standards for systems
development and implementation. However,
4GMF strongly supports ITU mission on IMT-Advanced
(the post program after IMT-2000). |
Q: What's the difference between 4GMF and
NGMN? A: NGMN is only targeted for
the higher layer mobile services and
applications evolved directly and indirectly
from WAP Forum, Open Mobile Alliance.
However, 4GMF covers the standardizations
from physical layer, MAC layer to the
network layer, transport layer as well the
service/application layers. Therefore, 4GMF
work includes RF, base-band, networks, OS
and applications. |
Q: Is 4GMF protected internationally? A:
Yes, 4GMF (Fourth Generation Mobile Forum)
is protected in both USA, China and
internationally. If you find any company
using this trademark in any country, please
report it to legal<at>4GMF.org accordingly.
4GMF has attorney base offices in US, China,
UK, Germany, France and Japan. |
