4G, short for fourth generation, is the fourth generation of mobile telecommunications technology, succeeding 3G and preceding 5G. A 4G system, in addition to the usual voice and other services of 3G, provides mobile ultra-broadband Internet access, for example to laptops with USB wireless modems, to smartphones, and to other mobile devices. Conceivable applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing, 3D television, and cloud computing.

Two 4G candidate systems are commercially deployed: the Mobile WiMAX standard (first used in South Korea in 2006), and the first-release Long Term Evolution (LTE) standard (in Oslo, Norway and Stockholm, Sweden since 2009). It has however been debated if these first-release versions should be considered to be 4G or not, as discussed in the technical definition section below.

In the United States, Sprint (previously Clearwire) has deployed Mobile WiMAX networks since 2008, while MetroPCS became the first operator to offer LTE service in 2010. USB wireless modems were among the first devices able to access these networks, with WiMAX smartphones becoming available during 2010, and LTE smartphones arriving in 2011. The consumer should note that 3G and 4G equipment made for other continents are not always compatible, because of different frequency bands. Mobile WiMAX is currently (April 2012) not available for the European market.

Technical understanding

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).

Since the first-release versions of Mobile WiMAX and LTE support much less than 1 Gbit/s peak bit rate, they are not fully IMT-Advanced compliant, but are often branded 4G by service providers. On December 6, 2010, ITU-R recognized that these two technologies, as well as other beyond-3G technologies that do not fulfill the IMT-Advanced requirements, could nevertheless be considered "4G", provided they represent forerunners to IMT-Advanced compliant versions and "a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed".

Mobile WiMAX Release 2 (also known as WirelessMAN-Advanced or IEEE 802.16m') and LTE Advanced (LTE-A) are IMT-Advanced compliant backwards compatible versions of the above two systems, standardized during the spring 2011,[citation needed] and promising speeds in the order of 1 Gbit/s. Services are expected in 2013.

As opposed to earlier generations, a 4G system does not support traditional circuit-switched telephony service, but all-Internet Protocol (IP) based communication such as IP telephony. As seen below, the spread spectrum radio technology used in 3G systems, is abandoned in all 4G candidate systems and replaced by OFDMA multi-carrier transmission and other frequency-domain equalization (FDE) schemes, making it possible to transfer very high bit rates despite extensive multi-path radio propagation (echoes). The peak bit rate is further improved by smart antenna arrays for multiple-input multiple-output (MIMO) communications.

The term "generation" used to name successive evolutions of radio networks in general is arbitrary. There are several interpretations, and no official definition has been made despite the consensus behind ITU-R's labels. From ITU-R's point of view, 4G is equivalent to IMT-Advanced which has specific performance requirements as explained below. According to operators, a generation of network refers to the deployment of a new non-backward-compatible technology. The end user expects the next generation of network to provide better performance and connectivity than the previous generation. Meanwhile, GSM, UMTS and LTE networks coexist; and end-users will only receive the benefit of the new generation architecture when they simultaneously: use an access device compatible with the new infrastructure, are within range of the new infrastructure, and pay the provider for access to that new infrastructure.


The nomenclature of the generations generally refers to a change in the fundamental nature of the service, non-backwards-compatible transmission technology, higher peak bit rates, new frequency bands, wider channel frequency bandwidth in Hertz, and higher capacity for many simultaneous data transfers (higher system spectral efficiency in bit/second/Hertz/site).

New mobile generations have appeared about every ten years since the first move from 1981 analog (1G) to digital (2G) transmission in 1992. This was followed, in 2001, by 3G multi-media support, spread spectrum transmission and at least 200 kbit/s peak bit rate, in 2011/2012 expected to be followed by "real" 4G, which refers to all-Internet Protocol (IP) packet-switched networks giving mobile ultra-broadband (gigabit speed) access.

While the ITU has adopted recommendations for technologies that would be used for future global communications, they do not actually perform the standardization or development work themselves, instead relying on the work of other standards bodies such as IEEE, The WiMAX Forum and 3GPP.

In mid-1990s, the ITU-R standardization organization released the IMT-2000 requirements as a framework for what standards should be considered 3G systems, requiring 200 kbit/s peak bit rate. In 2008, ITU-R specified the IMT-Advanced (International Mobile Telecommunications Advanced) requirements for 4G systems.

The fastest 3G-based standard in the UMTS family is the HSPA+ standard, which is commercially available since 2009 and offers 28 Mbit/s downstream (22 Mbit/s upstream) without MIMO, i.e. only with one antenna, and in 2011 accelerated up to 42 Mbit/s peak bit rate downstream using either DC-HSPA+ (simultaneous use of two 5 MHz UMTS carriers)[1] or 2x2 MIMO. In theory speeds up to 672 Mbit/s is possible, but has not been deployed yet. The fastest 3G-based standard in the CDMA2000 family is the EV-DO Rev. B, which is available since 2010 and offers 15.67 Mbit/s downstream.[citation needed]

IMT-Advanced requirements

This article uses 4G to refer to IMT-Advanced (International Mobile Telecommunications Advanced), as defined by ITU-R. An IMT-Advanced cellular system must fulfill the following requirements:[2]

In September 2009, the technology proposals were submitted to the International Telecommunication Union (ITU) as 4G candidates.[5] Basically all proposals are based on two technologies:

Implementations of Mobile WiMAX and first-release LTE are largely considered a stopgap solution that will offer a considerable boost until WiMAX 2 (based on the 802.16m spec) and LTE Advanced are deployed. The latter's standard versions were ratified in spring 2011, but are still far from being implemented.[2]

The first set of 3GPP requirements on LTE Advanced was approved in June 2008.[6] LTE Advanced was to be standardized in 2010 as part of Release 10 of the 3GPP specification. LTE Advanced will be based on the existing LTE specification Release 10 and will not be defined as a new specification series. A summary of the technologies that have been studied as the basis for LTE Advanced is included in a technical report.[7]

Some sources consider first-release LTE and Mobile WiMAX implementations as pre-4G or near-4G, as they do not fully comply with the planned requirements of 1 Gbit/s for stationary reception and 100 Mbit/s for mobile.[citation needed]

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, [citation needed] commonly referred to as '3.9G', [citation needed] which do not follow the ITU-R defined principles for 4G standards, [citation needed] but today can be called 4G according to ITU-R. [citation needed] A common argument for branding 3.9G systems as new-generation is that they use different frequency bands from 3G technologies ;[citation needed] that they are based on a new radio-interface paradigm ;[citation needed] and that the standards are not backwards compatible with 3G, [citation needed] whilst some of the standards are forwards compatible with IMT-2000 compliant versions of the same standards.[citation needed]

System standards

IMT-2000 compliant 4G standards

As of October 2010, ITU-R Working Party 5D approved two industry-developed technologies (LTE Advanced and WirelessMAN-Advanced)[8] for inclusion in the ITU’s International Mobile Telecommunications Advanced program (IMT-Advanced program), which is focused on global communication systems that would be available several years from now.

LTE Advanced

See also: 3GPP Long Term Evolution (LTE) below

LTE Advanced (Long Term Evolution Advanced) is a candidate for IMT-Advanced standard, formally submitted by the 3GPP organization to ITU-T in the fall 2009, and expected to be released in 2013. The target of 3GPP LTE Advanced is to reach and surpass the ITU requirements.[9] LTE Advanced is essentially an enhancement to LTE. It is not a new technology, but rather an improvement on the existing LTE network. This upgrade path makes it more cost effective for vendors to offer LTE and then upgrade to LTE Advanced which is similar to the upgrade from WCDMA to HSPA. LTE and LTE Advanced will also make use of additional spectrums and multiplexing to allow it to achieve higher data speeds. Coordinated Multi-point Transmission will also allow more system capacity to help handle the enhanced data speeds. Release 10 of LTE is expected to achieve the IMT Advanced speeds. Release 8 currently supports up to 300 Mbit/s of download speeds which is still short of the IMT-Advanced standards.[10]

IEEE 802.16m or WirelessMAN-Advanced

The IEEE 802.16m or WirelessMAN-Advanced evolution of 802.16e is under development, with the objective to fulfill the IMT-Advanced criteria of 1 Gbit/s for stationary reception and 100 Mbit/s for mobile reception.[11]

Forerunner versions

3GPP Long Term Evolution (LTE)

See also: LTE Advanced above
Telia-branded Samsung LTE modem

The pre-4G 3GPP Long Term Evolution (LTE) technology is often branded "4G-LTE", but the first LTE release does not fully comply with the IMT-Advanced requirements. LTE has a theoretical net bit rate capacity of up to 100 Mbit/s in the downlink and 50 Mbit/s in the uplink if a 20 MHz channel is used — and more if multiple-input multiple-output (MIMO), i.e. antenna arrays, are used.

The physical radio interface was at an early stage named High Speed OFDM Packet Access (HSOPA), now named Evolved UMTS Terrestrial Radio Access (E-UTRA). The first LTE USB dongles do not support any other radio interface.

The world's first publicly available LTE service was opened in the two Scandinavian capitals, Stockholm (Ericsson and Nokia Siemens Networks systems) and Oslo (a Huawei system) on December 14, 2009, and branded 4G. The user terminals were manufactured by Samsung.[12] As of Nov 2012, the five publicly available LTE services in the United States are provided by MetroPCS,[13] Verizon Wireless,[14] AT&T Mobility, U.S. Cellular,[15] Sprint,[16] and T-Mobile US.[17]

T-Mobile Hungary launched a public beta test (called friendly user test) on 7 October 2011, and has offered commercial 4G LTE services since 1 January 2012.[citation needed]

In South Korea, SK Telecom and LG U+ have enabled access to LTE service since 1 July 2011 for data devices, slated to go nationwide by 2012.[18] KT Telecom closed its 2G service by March 2012, and complete the nationwide LTE service in the same frequency around 1.8 GHz by June 2012.

In the United Kingdom, LTE services were launched by EE in October 2012,[19] and by O2 and Vodafone in August 2013.[20]

Data speeds of LTE

Peak upload 50 Mbit/s

Mobile WiMAX (IEEE 802.16e)

The Mobile WiMAX (IEEE 802.16e-2005) mobile wireless broadband access (MWBA) standard (also known as WiBro in South Korea) is sometimes branded 4G, and offers peak data rates of 128 Mbit/s downlink and 56 Mbit/s uplink over 20 MHz wide channels. [citation needed]

In June 2006, the world's first commercial mobile WiMAX service was opened by KT in Seoul, South Korea.[21]

Sprint has begun using Mobile WiMAX, as of 29 September 2008, branding it as a "4G" network even though the current version does not fulfil the IMT Advanced requirements on 4G systems.[22]

In Russia, Belarus and Nicaragua WiMax broadband internet access is offered by a Russian company Scartel, and is also branded 4G, Yota.

Peak download 128 Mbit/s
Peak upload 56 Mbit/s

TD-LTE for China market

Just when Long-Term Evolution (LTE) and WiMax are vigorously promoting in the global telecommunications industry, the former (LTE) is also the most powerful 4G mobile communications leading technology, and quickly occupied the Chinese market. TD-LTE, one of the two variants of the LTE air interface technologies, is not yet mature, but many domestic and international wireless carriers one after another turn to TD-LTE.

IBM's data show that 67% of the operators are considering LTE, because this is the main source of their future market. The above news also confirmed this statement of IBM. While only 8% of the operators are considering the use of WiMAX. WiMax can provide the fastest network transmission to its customers on the market, but still could challenge LTE.

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. After a series of field trials, is expected to be released into the commercial phase in the next two years. Ulf Ewaldsson, Ericsson's vice president said: "the Chinese Ministry of Industry and China Mobile in the fourth quarter of this year will hold a large-scale field test, by then, Ericsson will help the hand." But viewing from the current development trend, whether this standard advocated by China Mobile will be widely recognized by the international market is still debatable.

Discontinued candidate systems

UMB (formerly EV-DO Rev. C)

Main article: Ultra Mobile Broadband

UMB (Ultra Mobile Broadband) was the brand name for a discontinued 4G project within the 3GPP2 standardization group to improve the CDMA2000 mobile phone standard for next generation applications and requirements. In November 2008, Qualcomm, UMB's lead sponsor, announced it was ending development of the technology, favouring LTE instead.[23] The objective was to achieve data speeds over 275 Mbit/s downstream and over 75 Mbit/s upstream.


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

iBurst and MBWA (IEEE 802.20) systems

The iBurst system (or HC-SDMA, High Capacity Spatial Division Multiple Access) was at an early stage considered to be a 4G predecessor. It was later further developed into the Mobile Broadband Wireless Access (MBWA) system, also known as IEEE 802.20.

Principal technologies in all candidate systems

Key features

The following key features can be observed in all suggested 4G technologies:

As opposed to earlier generations, 4G systems do not support circuit switched telephony. IEEE 802.20, UMB and OFDM standards[27] lack soft-handover support, also known as cooperative relaying.

Multiplexing and access schemes

This section may contain information not important or relevant to the article's subject. Please help improve this section. (May 2010) (Learn how and when to remove this message)

Recently, new access schemes like Orthogonal FDMA (OFDMA), Single Carrier FDMA (SC-FDMA), Interleaved FDMA, and Multi-carrier CDMA (MC-CDMA) are gaining more importance for the next generation systems. These are based on efficient FFT algorithms and frequency domain equalization, resulting in a lower number of multiplications per second. They also make it possible to control the bandwidth and form the spectrum in a flexible way. However, they require advanced dynamic channel allocation and adaptive traffic scheduling.

WiMax is using OFDMA in the downlink and in the uplink. For the LTE (telecommunication), OFDMA is used for the downlink; by contrast, Single-carrier FDMA is used for the uplink since OFDMA contributes more to the PAPR related issues and results in nonlinear operation of amplifiers. IFDMA provides less power fluctuation and thus requires energy-inefficient linear amplifiers. Similarly, MC-CDMA is in the proposal for the IEEE 802.20 standard. These access schemes offer the same efficiencies as older technologies like CDMA. Apart from this, scalability and higher data rates can be achieved.

The other important advantage of the above-mentioned access techniques is that they require less complexity for equalization at the receiver. This is an added advantage especially in the MIMO environments since the spatial multiplexing transmission of MIMO systems inherently require high complexity equalization at the receiver.

In addition to improvements in these multiplexing systems, improved modulation techniques are being used. Whereas earlier standards largely used Phase-shift keying, more efficient systems such as 64QAM are being proposed for use with the 3GPP Long Term Evolution standards.

IPv6 support

Main articles: Network layer, Internet protocol, and IPv6

Unlike 3G, which is based on two parallel infrastructures consisting of circuit switched and packet switched network nodes, 4G will be based on packet switching only. This will require low-latency data transmission.

By the time that 4G was deployed, the process of IPv4 address exhaustion was expected to be in its final stages. Therefore, in the context of 4G, IPv6 is essential to support a large number of wireless-enabled devices. By increasing the number of IP addresses available, IPv6 removes the need for network address translation (NAT), a method of sharing a limited number of addresses among a larger group of devices, although NAT will still be required to communicate with devices that are on existing IPv4 networks.

As of June 2009, Verizon has posted specifications that require any 4G devices on its network to support IPv6.[28]

Advanced antenna systems

Main articles: MIMO and MU-MIMO

The performance of radio communications depends on an antenna system, termed smart or intelligent antenna. Recently, multiple antenna technologies are emerging to achieve the goal of 4G systems such as high rate, high reliability, and long range communications. In the early 1990s, to cater for the growing data rate needs of data communication, many transmission schemes were proposed. One technology, spatial multiplexing, gained importance for its bandwidth conservation and power efficiency. Spatial multiplexing involves deploying multiple antennas at the transmitter and at the receiver. Independent streams can then be transmitted simultaneously from all the antennas. This technology, called MIMO (as a branch of intelligent antenna), multiplies the base data rate by (the smaller of) the number of transmit antennas or the number of receive antennas. Apart from this, the reliability in transmitting high speed data in the fading channel can be improved by using more antennas at the transmitter or at the receiver. This is called transmit or receive diversity. Both transmit/receive diversity and transmit spatial multiplexing are categorized into the space-time coding techniques, which does not necessarily require the channel knowledge at the transmitter. The other category is closed-loop multiple antenna technologies, which require channel knowledge at the transmitter.

Open-wireless Architecture and Software-defined radio (SDR)

One of the key technologies for 4G and beyond is called Open Wireless Architecture (OWA), supporting multiple wireless air interfaces in an open architecture platform.

SDR is one form of open wireless architecture (OWA). Since 4G is a collection of wireless standards, the final form of a 4G device will constitute various standards. This can be efficiently realized using SDR technology, which is categorized to the area of the radio convergence.

History of 4G and pre-4G technologies

The 4G system was originally envisioned by the Defense Advanced Research Projects Agency (DARPA).[citation needed] The DARPA selected the distributed architecture and end-to-end Internet protocol (IP), and believed at an early stage in peer-to-peer networking in which every mobile device would be both a transceiver and a router for other devices in the network, eliminating the spoke-and-hub weakness of 2G and 3G cellular systems.[29][page needed] Since the 2.5G GPRS system, cellular systems have provided dual infrastructures: packet switched nodes for data services, and circuit switched nodes for voice calls. In 4G systems, the circuit-switched infrastructure is abandoned and only a packet-switched network is provided, while 2.5G and 3G systems require both packet-switched and circuit-switched network nodes, i.e. two infrastructures in parallel. This means that in 4G, traditional voice calls are replaced by IP telephony.

Deployment plans


Telecom giant Etisalat Afghanistan, the first telecom company to launch 3.75G services in Afghanistan on 19th Feb, 2013 announced the commencement of test of its Long-term Evolution (LTE) 4G mobile network.


Safaricom, a telecommunication company in Kenya, began its setup of a 4G network in October 2010 after the now retired Kenya Tourist Board Chairman, Michael Joseph, regarded their 3G network as a white elephant. Huawei was given the contract and the network is set to go fully commercial by the end of Q1 of 2011 but was yet to establish the network by the end of 2012.


Telstra announced on 15 February 2011, that it intends to upgrade its current Next G network to 4G with Long Term Evolution (LTE) technology in the central business districts of all Australian capital cities and selected regional centers by the end of 2011.[64]

Telstra launched the country's first 4G network (FD-LTE) in September 2011 claiming "2–100 Mbps" speeds and announced an "aggressive" expansion of that network in 2012.[65][66]

Telstra will use a mixture of 10 MHz and 15 MHz bandwidth in the 1800 MHz band.

Optus have established a 4G (FD-LTE) network using 10 MHz (out of 15 MHz available) bandwidth in the 1800 MHz band and added the 2.3 GHz band for 4G TD-LTE after acquiring Vivid Wireless in 2012.[67]

Vodafone Australia have indicated their roll out of 4G FD-LTE will use 20 MHz bandwidth and initially support Cat 3 devices at launch, then quickly move to support Cat 4 devices.

Australian Communications and Media Authority (ACMA) will auction 700 MHz "digital dividend" and 2600 MHz spectrum for the provision of 4G FD-LTE services in April 2013. Telstra and Optus are expected to participate in both, while Vodafone has stated it will only participate in the 2600 MHz auction.

On 19 December 2013 Optus claims to set up the world's first TD-LTE Advanced carrier aggregation network. The company achieved a throughput of 520 Mbit/s, by combining four 20 MHz channels of the 2300 MHz spectrum band into 80 MHz.[68][69]


In August, 2009 Huawei and T-Mobile introduced Europe's largest trial LTE network. Both companies set up 60 cells in Innsbruck which are since July 2009 in service.[70]

In June, 2010 A1 Telekom Austria tested LTE with its partner Huawei in Vienna.[71]

On October 18, 2010, the allocation procedure for 2600 MHz frequency band was completed.[72] The following figure shows the current allocation for this frequency band:[73][74]

A1 Telekom Austria started the first commercial (FDD-)LTE service in Austria on 19 October 2010. Iniatially A1 Telekom Austria covered Vienna with 49 eNodeB's and St. Pölten with 3 eNodeB's.[75]

On 28 July 2011, T-Mobile Austria launched commercial LTE service in Vienna, Linz, Graz and Innsbruck.[76]

After A1 Telekom Austria and T-Mobile Austria started their LTE service Austria's smallest operator 3 introduced LTE commercially on the 18th of November 2011.[77]

In March, 2012, A1 Telekom Austria integrated Circuit-switched fallback (CSFB) and launched the first LTE Smartphone (HTC Velocity 4G) for the Austrian market.[75]

At the end of November, 2012, A1 Telekom Austria claims to reach 30% of the Austrian population with its LTE network. At this time, according to a press release, 800 EnodeB's were used.[78]

At the beginning of July, 2013, A1 Telekom Austria announced that the company has switched on their 1000th eNodeB.[79]

At the beginning of September, 2013, Bregenz, Dornbirn and Lustenau are covered by A1 Telekom Austria LTE.[80]

On 7 October 2013, T-Mobile Austria started LTE service for Smartphones. The company also announced plans for further LTE coverage. Until the end of 2013 parts of the city Bregenz, Klagenfurt, Salzburg and St. Pölten will be covered with LTE.[81]

On October 21, 2013, the multiband spectrum auction was completed. The following figure shows the current allocation for this frequency band:[82]

At the end of November, 2013, Huchtison 3 and T-Mobile Austria intent to appeal auction results.[83][84]

On 4 December 2013, according to A1 Telekom Austria Klosterneuburg is covered with LTE.[85]

On 21 August 2012, the United Kingdom's regulator Ofcom allowed EE, the owner of the Orange and T-Mobile networks, to use its existing spectrum in the 1,800 MHz band to launch fourth-generation (4G) mobile services.[198] As part of Ofcom's approval of the company's roll-out of 4G it was announced on 22 August that 3 had acquired part of EE's 1,800 MHz spectrum for part of their own 4G network.[199] The 4G service from EE was announced on 11 September 2012 and launched on 30 October initially in 11 cities.[200][201] The network aims to cover 70% of the UK by 2013 and 98% by 2014.[202]

On 12 November 2012 Ofcom published final regulations and a timetable[203] for the 4G mobile spectrum auction. It also launched a new 4G consumer page,[204] providing information on the upcoming auction and the consumer benefits that new services will deliver. Ofcom auctioned off the UK-wide 4G spectrum previously used by the country's analogue television signals in the 800 MHz band as well as in the 2,600 MHz band.[205] On 20 February 2013, the winners of the 4G spectrum auction were announced by Ofcom.[206] The four major networks, EE, O2, Vodafone and 3, were awarded spectrum along with Niche Spectrum Ventures Ltd (a subsidiary of BT Group plc).

On 9 July 2013, Ofcom announced that mobile network operators would be allowed to repurpose their existing 2G and 3G spectrum, specifically in the 900, 1,800 and 2,100 MHz bands, for 4G services.[207]

Both O2 and Vodafone launched their 4G networks on 29 August 2013.[208][209] The 3 network launched their 4G service in December 2013, initially it was only available to a selected few thousand customers in London preceding a nationwide rollout in 2014.[210][211]

LTE MVNE: On 1 April 2014, Plintron World's largest Multi-Country MVNE Enables LYCAMOBILE to be in the 4G League in UK. Plintron have completed it's LTE core interoperability with O2 UK, to enable LYCAMOBILE 4G data services.

International LTE Roaming: AT&T signed LTE roaming agreement with EE on the 17th of December 2013.[212] EE announced further LTE roaming agreements with Orange in France and Spain on March 2014. Customers of EE will access the LTE networks of both operators immediately. The company also announced in a press release that it will extend its 4G coverage across major roaming destination including the USA, Italy, Germany, Switzerland and the Netherlands by the Summer.[213][214]

At the beginning of May 2014, Vodafone added 4G roaming for their Red 4G customers in Greece, Italy, Portugal and Spain.[215]

On 12 June 2014, Vodafone announced LTE rollout for Belfast over the summer.[216]

United States

Verizon Wireless, AT&T, T-Mobile and Sprint Corporation all use 4G LTE. None of them use WiMAX.

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.

Sprint offers a 3G/4G connection plan, currently[when?] available in select cities in the United States.[46] It delivers rates up to 10 Mbit/s. Sprint has also launched an LTE network in early 2012.[217]

Verizon Wireless has announced[when?] that it plans to augment its CDMA2000-based EV-DO 3G network in the United States with LTE, and is supposed to complete a rollout of 175 cities by the end of 2011, two thirds of the US population by mid-2012, and cover[citation needed] the existing 3G network by the end of 2013.[218] AT&T, along with Verizon Wireless, has chosen to migrate toward LTE from 2G/GSM and 3G/HSPA by 2011.[219]

Sprint had deployed WiMAX technology which it has labeled 4G as of October 2008. It was the first US carrier to offer a WiMAX phone.[220]

The U.S. FCC is exploring[when?] the possibility of deployment and operation of a nationwide 4G public safety network which would allow first responders to seamlessly communicate between agencies and across geographies, regardless of devices. In June 2010 the FCC released a comprehensive white paper which indicates that the 10 MHz of dedicated spectrum currently allocated from the 1700 MHz spectrum for public safety will provide adequate capacity and performance necessary for normal communications as well as serious emergency situations.[221]

International LTE Roaming: AT&T signed LTE roaming agreement with EE on the 17th of December 2013.[212]

Beyond 4G research

Main article: 5G

A major issue in 4G systems is to make the high bit rates available in a larger portion of the cell, especially to users in an exposed position in between several base stations. In current research, this issue is addressed by macro-diversity techniques, also known as group cooperative relay, and also by Beam-Division Multiple Access (BDMA).[222]

Pervasive networks are an amorphous and at present entirely hypothetical concept where the user can be simultaneously connected to several wireless access technologies and can seamlessly move between them (See vertical handoff, IEEE 802.21). These access technologies can be Wi-Fi, UMTS, EDGE, or any other future access technology. Included in this concept is also smart-radio (also known as cognitive radio) technology to efficiently manage spectrum use and transmission power as well as the use of mesh routing protocols to create a pervasive network.
