  4G - Wikipedia, the free encyclopedia
The official designation from the IEEE for 4G is Beyond 3G.
Thus, 4G would refer to whatever is deployed in the 2010–2015 period, assuming 3G deployment spans the 2000–2009 period.
The killer application of 4G is not clear, but video is one of the big differences between 4G and 3G.

 Time for 4G? Telecommunications Americas - Find Articles   (Site not responding. Last check: 2007-10-10)
In other words, 4G must be capable of reducing cost to operators and translating the desktop experience to the mobile world.
An important element to 4G should be an IP-centric cellular WAN (not WLAN) that eliminates circuit switching and distributes switching intelligence throughout the network rather than to a centralized location.
If 4G can fill in some of the pieces of the high-speed wireless network, as these technologies will be able to do, then it will certainly gain a niche in the market.

 What is 4G? - a definition from Whatis.com - see also: 4-G, fourth generation (via CobWeb/3.1 planetlab2.tamu.edu)   (Site not responding. Last check: 2007-10-10)
4G is the short term for fourth-generation wireless, the stage of broadband mobile communications that will supercede the third generation (3G).
While neither standards bodies nor carriers have concretely defined or agreed upon what exactly 4G will be, it is expected that end-to-end IP and high-quality streaming video will be among 4G's distinguishing features.
When fully implemented, 4G is expected to enable pervasive computing, in which simultaneous connections to multiple high-speed networks provide seamless handoffs throughout a geographical area.

 CommsDesign - Making the Leap to 4G Wireless
The move to 4G is complicated by attempts to standardize on a single 3G protocol.
Given that 4G is based on a multicarrier technique, key baseband components for the transmitter and receiver are the FFT and its inverse (IFFT).
For a 4G receiver using a 5-MHz RF bandwidth, 16 QAM modulation and NF of 3 dB, the receiver sensitivity is -87 dBm.

 Fourth generation (4G) wireless communications
4G mobile data transmission rates are planned to be up to 20 megabits per second.
For 4G data rates up to 20 Megabytes per second are planned.

 Beijing 2008: The First 4G Wireless Olympic Games ?
Peer-to-peer networks, where every device is both a transceiver and a router/repeater for other devices in the network, eliminates this spoke-and-hub weakness of cellular architectures, because the elimination of a single node does not disable the network.
The final definition of “4G” will have to include something as simple as this: if a consumer can do it at home or in the office while wired to the Internet, that consumer must be able to do it wirelessly in a fully mobile environment.
The growing middle class, and their new-found ability to purchase automobiles, is increasing the number of passenger vehicles on the road at a staggering annual rate of 30%.

 Mobile Handset DesignLine | Make sure you're ready for 4G
In this context, 4G refers to the development of a technology change around a new air interface that provides higher data rates, or around the way we transfer data from an end-to-end point of view.
One idea behind 4G is the development of a wireless link at 100 Mbits/s while moving and 1 Gbit/s when stationary.
4G communication platforms will require networking processing power, applications support, a MAC, digital baseband, and analog front-end, and an efficient and low-power LNA and PA, which is similar to what's required today.

 CommsDesign - Making the Leap to 4G Wireless (via CobWeb/3.1 planetlab2.tamu.edu)   (Site not responding. Last check: 2007-10-10)
Table 1 compares some of the key parameters of 3G and 4G (4G does not have any solid specification as of yet, so the parameters rely on general proposals).
With the wider bandwidth system and high PAVR associated with 4G, it will be difficult to achieve good performance without help of linearity techniques (for example, predistortion of the signal to the PA).
To achieve the goals of 4G, technology will need to improve significantly in order to handle the intensive algorithms in the baseband processing and the wide bandwidth of a high PAVR signal.

 The Hype And Confusion About 4G - Trends - Network Computing
When I questioned IP Wireless about the use of the term "4G" for this service, the company said it was the operator's decision to convey the sense that the service would provide greater capability than existing 3G networks such as UMTS.
There is no official 4G standardization yet, but early "industry consensus" indicates 1-Gbps peak rates, typical throughputs of 100 Mbps, network agility and best-of-breed radio techniques.
The current 3GPP timeline for 4G deployment is around 2012, although I consider that a best case given all the interim steps.

 Fast Forward to 4G? - Cover Story - Network Computing
Fourth-generation (4G) cellular services, intended to provide mobile data at rates of 100Mbits/sec or more, were originally scheduled for 2010.
Given their past record of hype, there are good reasons not to believe the more outlandish predictions, but there are also reasons to think that some aspects of 4G could be real.
While other wireless generations have focused on voice, perhaps combined with other types of traffic such as short messages (see table), MBS is intended to be service-independent: It's a big pipe for data, which devices can use for any applications.

 CommsDesign - Samsung locates 4G research group in London
I think 4G is likely to build on existing technology, just as 3G builds on 2.5G.
Other communications researchers have said that 4G might include a superior form of radio subsystem that could "sniff" radio waves to find out which of the multitude of cellular communications standards are available.
But it is not clear whether 4G could harness this capability along with other innovative modulation schemes on existing or new carrier frequencies.

However, MCM increases the peak-to-average ratio (PAVR) of the signal, and to overcome ISI a cyclic extension or guard band must be added to the data.
In 4G systems rate-adaptive coding schemes can be used which can make use of the channel information from the measured parameters or feedback from the Mobile Terminal (MT).
A conservative approach might be proposed for the 4G systems because of the wide variety of QoS requirements.

 All IP Wireless, All the Time (via CobWeb/3.1 planetlab2.tamu.edu)   (Site not responding. Last check: 2007-10-10)
Mobile IP, together with SCTP, SLP, Diameter, and IP RAN describe protocols and technologies that Kempf, Wood, Dave Frascone, their colleagues, and team leader Jackson Wong are pioneering in behalf of a quest: the fourth-generation IP-based wireless communications network.
The goal of 4G is to "replace the current proliferation of core cellular networks with a single worldwide cellular core network standard based on IP for control, video, packet data, and VoIP," says Kempf.
According to Kempf, 4G "equipment costs are four to ten times cheaper than equivalent circuit-switched equipment for 2G and 3G wireless infrastructure." An open systems IP wireless environment would probably further reduce costs for service providers by ushering in an era of real equipment interoperability.
