Discontinued candidate systems[edit]
UMB (formerly EV-DO Rev. C)[edit]
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.
[24] The objective was to achieve data speeds over 275 Mbit/s downstream and over 75 Mbit/s upstream.
Flash-OFDM[edit]
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[edit]
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.
Data rate comparison[edit]
Principal technologies in all candidate systems[edit]
Key features[edit]
The following key features can be observed in all suggested 4G technologies:
- Physical layer transmission techniques are as follows:[27]
- MIMO: To attain ultra high spectral efficiency by means of spatial processing including multi-antenna and multi-user MIMO
- Frequency-domain-equalization, for example multi-carrier modulation (OFDM) in the downlink or single-carrier frequency-domain-equalization (SC-FDE) in the uplink: To exploit the frequency selective channel property without complex equalization
- Frequency-domain statistical multiplexing, for example (OFDMA) or (single-carrier FDMA) (SC-FDMA, a.k.a. linearly precoded OFDMA, LP-OFDMA) in the uplink: Variable bit rate by assigning different sub-channels to different users based on the channel conditions
- Turbo principle error-correcting codes: To minimize the required SNR at the reception side
- Channel-dependent scheduling: To use the time-varying channel
- Link adaptation: Adaptive modulation and error-correcting codes
- Mobile-IP utilized for mobility
- IP-based femtocells (home nodes connected to fixed Internet broadband infrastructure)
As opposed to earlier generations, 4G systems do not support circuit switched telephony. IEEE 802.20, UMB and OFDM standards
[28] lack
soft-handover support, also known as
cooperative relaying.
Multiplexing and access schemes[edit]
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.
IPv6 support[edit]
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 addressesavailable, 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.
Advanced antenna systems[edit]
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)[edit]
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[edit]
Deployment plans[edit]
Afghanistan[edit]
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.
As of 11 November 2014 Rwanda became the newest country to begin introducing 4G LTE services in its capital Kigali, Rw after months of testing.
[64] 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 was set to go fully commercial by the end of Q1 of 2011 but was yet to establish the network by the end of 2012.
Australia[edit]
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.
[65]
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.
[66][67]
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.
[68]
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.

The Netherlands[edit]
After the multiband spectrum auction in Q4-2012
KPN announced that the deployment of 4G services would start in February 2013 and that nationwide coverage will be available in Q1 2014.
[149]
Vodafone has launched the 4G network in August 2013,
[150] while T-Mobile announced only a roll-out in Q4 of 2013.
[151] Tele2 will launch their network probably in the same time as T-Mobile, because they are using site/antenna-sharing.
As of Q1 2014, KPN will be the first network provider that has deployed a nationwide 4G network in the Netherlands.
[152] Expectations are that both KPN and Vodafone will reach nationwide coverage in 2014. T-Mobile and Tele2, being lower-budget providers, will probably never reach a nationwide coverage, as is the case with their existing 2G and 3G networks. Tele2 will stay a MVNO (i.e., Tele2 will buy network capacity) on the T-Mobile network for 2G/3G Services and a MVNO on the KPN network for 2G/3G Business Services (previously Versatel).
[153]
Network operator ZUM's plans remain unknown; only a small 2.6 GHz LTE network would be required to meet regulatory requirements.

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 routingprotocols to create a pervasive network.
