4G Technical definition

1 In March 2008, the International Telecommunications Union-Radio

communications sector (ITU-R) specified a set of requirements for 4G standards, named the International Mobile Telecommunications

Advanced (IMT-Advanced) specification, setting peak speed requirements for 4G service at 100 megabits per second (Mbit/s) for high mobility communication (such as from trains and cars)

and 1 gigabit per second (Gbit/s) for low mobility communication (such as pedestrians and

stationary users).


4G IMT-Advanced requirements

1 Confusion has been caused by some mobile carriers who have launched

products advertised as 4G but which according to some sources are pre-

4G versions, commonly referred to as '3.9G', which do not follow the ITU-R defined principles for 4G standards,

but today can be called 4G according to ITU-R


4G TD-LTE for China market

1 TD-LTE is not the first 4G wireless mobile broadband network data

standard, but it is China's 4G standard that was amended and

published by China's largest telecom operator - China Mobile


4G Flash-OFDM

1 At an early stage the Flash-OFDM system was expected to be further developed into a 4G

standard.


4G Multiplexing and access schemes

1 The Migration to 4G standards incorporates elements of many early technologies and

many solutions use code (a cypher), frequency or time as the basis of

multiplexing the spectrum more efficiently. While Spectrum is considered finite,

Cooper's Law has shown that we have developed more efficient ways of using spectrum just as the Moore's law has

shown our ability to increase processing.


4G United States

1 On September 20, 2007, Verizon Wireless announced plans for a joint

effort with the Vodafone Group to transition its networks to the 4G

standard LTE. On December 9, 2008, Verizon Wireless announced their

intentions to build and roll out an LTE network by the end of 2009. Since

then, Verizon Wireless has said that they will start their roll out by the

end of 2010.https://store.theartofservice.com/the-4g-standard-toolkit.html

5G

1 Although updated standards that define capabilities beyond those

defined in the current 4G standards are under consideration, those new capabilities are still being grouped under the current 4G standards.


HTC Evo 4G - Smartphone connectivity

1 The EVO features a CDMA cellular radio that supports 3G EVDO, Revisions 0, A, and the yet-undeployed B allowing faster download

and upload speeds, greater power efficiency; and WiMAX, a protocol known as 802.16e, which features speeds of up to 10 Mbit/s on the downlink and 1.5 Mbit/s on the

uplink. The device is marketed as a 4G phone, WiMAX is considered to be a 4G

technology based on 4G standards recently set by ITU-R.


HTC Evo Shift 4G - Smartphone connectivity

1 The EVO Shift features a CDMA cellular radio that supports 3G EVDO, revisions 0, A, and

the as yet undeployed B allowing faster download and upload speeds, and better

power efficiency. As well as WiMAX, protocol known as 802.16e, which features speeds of up to 10Mbit/s on the downlink, and 1Mbit/s on the uplink. The device is marketed as a 4G phone, WiMAX is considered to be a 4G technology based on 4G standards set by

ITU-R.


Verizon Wireless - Network

1 However, on September 20, 2007, Verizon Wireless announced a joint effort with the Vodafone Group to transition their networks to the 4G

standard 3GPP Long Term Evolution|LTE and on November 29, 2007, Verizon Wireless announced that

they would start LTE trials in 2008


Yota - History

1 At that point, Yota had no interest to use a 4G standard network in a commercial or test

mode


History of smart antennas - Commercialization of 4G MIMO

1 WiMAX was developed as an alternative to cellular standards, is based on the 802.16e standard, and uses MIMO-OFDM to deliver

speeds up to 138 Mbit/s. The more advanced 802.16m standard enabled download speeds up

to 1 Gbit/s. A nationwide WiMAX network was built in the United States by Clearwire, a

subsidiary of Sprint-Nextel, covering 130 million pops by mid-2012. Clearwire subsequently

announced plans to deploy LTE (the cellular 4G standard) covering 31 cities by mid-2013.
