4G Standard

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

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 e, 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 e, 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

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 e standard, and uses MIMO-OFDM to deliver speeds up to 138 Mbit/s. The more advanced m 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 Clearwire subsequently announced plans to deploy LTE (the cellular 4G standard) covering 31 cities by mid
