The telecommunications industries within the sector of information and communication technology is made up of all telecommunications / telephone companies and internet service providers and plays a crucial role in the evolution of mobile communications and the information society .
39-665: The Nigerian Communications Commission ( NCC ) is the independent regulatory authority for the telecommunications industry in Nigeria. The NCC was created under Decree number 75 by the Federal Military Government of Ibrahim Babangida in Nigeria on 24 November 1992. The NCC was charged with the responsibility of regulating the supply of telecommunications services and facilities, promoting competition, and setting performance standards for telephone services in Nigeria. The Decree has been abrogated and replaced with
78-464: A Belgian company, has also worked to build small cells for LTE-TDD networks. Trials of LTE-TDD technology began as early as 2010, with Reliance Industries and Ericsson India conducting field tests of LTE-TDD in India , achieving 80 megabit-per second download speeds and 20 megabit-per-second upload speeds. By 2011, China Mobile began trials of the technology in six cities. Although initially seen as
117-411: A coalition of international companies that worked to develop and test the technology. China Mobile was an early proponent of LTE-TDD, along with other companies like Datang Telecom and Huawei , which worked to deploy LTE-TDD networks, and later developed technology allowing LTE-TDD equipment to operate in white spaces —frequency spectra between broadcast TV stations. Intel also participated in
156-618: A combined LTE-TDD and LTE-FDD network in Poland, and by April 2012, ZTE Corporation had worked to deploy trial or commercial LTE-TDD networks for 33 operators in 19 countries. In late 2012, Qualcomm worked extensively to deploy a commercial LTE-TDD network in India, and partnered with Bharti Airtel and Huawei to develop the first multi-mode LTE-TDD smartphone for India. In Japan , SoftBank Mobile launched LTE-TDD services in February 2012 under
195-530: A different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. Because LTE frequencies and bands differ from country to country, only multi-band phones can use LTE in all countries where it is supported. The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE
234-485: A number of carriers promoting VoLGA (Voice over LTE Generic Access) as an interim solution. The idea was to use the same principles as GAN (Generic Access Network, also known as UMA or Unlicensed Mobile Access), which defines the protocols through which a mobile handset can perform voice calls over a customer's private Internet connection, usually over wireless LAN. VoLGA however never gained much support, because VoLTE ( IMS ) promises much more flexible services, albeit at

312-460: A series of tests of voice over LTE ( VoLTE) calls on China Mobile's TD-LTE network. The next month, Nokia Solutions and Networks and Sprint announced that they had demonstrated throughput speeds of 2.6 gigabits per second using a LTE-TDD network, surpassing the previous record of 1.6 gigabits per second. Much of the LTE standard addresses the upgrading of 3G UMTS to what will eventually be 4G mobile communications technology. A large amount of
351-693: A technology utilized by only a few countries, including China and India, by 2011 international interest in LTE-TDD had expanded, especially in Asia, in part due to LTE-TDD's lower cost of deployment compared to LTE-FDD. By the middle of that year, 26 networks around the world were conducting trials of the technology. The Global LTve (GTI) was also started in 2011, with founding partners China Mobile, Bharti Airtel , SoftBank Mobile , Vodafone , Clearwire , Aero2 and E-Plus . In September 2011, Huawei announced it would partner with Polish mobile provider Aero2 to develop

LTE supports scalable carrier bandwidths , from 1.4 MHz to 20 MHz and supports both frequency division duplexing (FDD) and time-division duplexing (TDD). The IP-based network architecture, called the Evolved Packet Core (EPC) designed to replace
429-481: A voice call on a non-VoLTE-enabled network or device, LTE handsets will fall back to old 2G or 3G networks for the duration of the call. To ensure compatibility, 3GPP demands at least AMR-NB codec (narrow band), but the recommended speech codec for VoLTE is Adaptive Multi-Rate Wideband , also known as HD Voice . This codec is mandated in 3GPP networks that support 16 kHz sampling. Fraunhofer IIS has proposed and demonstrated "Full-HD Voice", an implementation of

The requirements were set forth by the ITU-R organisation in the IMT Advanced specification; but, because of market pressure and the significant advances that WiMAX , Evolved High Speed Packet Access , and LTE bring to
585-708: Is generally cheaper to access, and has less traffic. Further, the bands for LTE-TDD overlap with those used for WiMAX , which can easily be upgraded to support LTE-TDD. Despite the differences in how the two types of LTE handle data transmission, LTE-TDD and LTE-FDD share 90 percent of their core technology, making it possible for the same chipsets and networks to use both versions of LTE. A number of companies produce dual-mode chips or mobile devices, including Samsung and Qualcomm , while operators CMHK and Hi3G Access have developed dual-mode networks in Hong Kong and Sweden, respectively. The creation of LTE-TDD involved

High-speed internet access for computer-based data applications such as broadband information services and interactive entertainment is pervasive. Digital subscriber line (DSL) is the main broadband telecom technology. The fastest growth comes from ( value-added ) services delivered over mobile networks . The telecom sector continues to be at
663-495: Is one of the two mobile data transmission technologies of the Long-Term Evolution (LTE) technology standard, the other being Long-Term Evolution Frequency-Division Duplex ( LTE-FDD ). While some companies refer to LTE-TDD as "TD-LTE" for familiarity with TD-SCDMA , there is no reference to that abbreviation anywhere in the 3GPP specifications. There are two major differences between LTE-TDD and LTE-FDD: how data
702-703: Is uploaded and downloaded, and what frequency spectra the networks are deployed in. While LTE-FDD uses paired frequencies to upload and download data, LTE-TDD uses a single frequency, alternating between uploading and downloading data through time. The ratio between uploads and downloads on a LTE-TDD network can be changed dynamically, depending on whether more data needs to be sent or received. LTE-TDD and LTE-FDD also operate on different frequency bands, with LTE-TDD working better at higher frequencies, and LTE-FDD working better at lower frequencies. Frequencies used for LTE-TDD range from 1850 MHz to 3800 MHz, with several different bands being used. The LTE-TDD spectrum

The LTE specification provides downlink peak rates of 300 Mbit/s, uplink peak rates of 75 Mbit/s and QoS provisions permitting
975-494: The adoption of LTE, carriers will have to re-engineer their voice call network. Four different approaches sprang up: One additional approach which is not initiated by operators is the usage of over-the-top content (OTT) services, using applications like Skype and Google Talk to provide LTE voice service. Most major backers of LTE preferred and promoted VoLTE from the beginning. The lack of software support in initial LTE devices, as well as core network devices, however led to
1014-678: The caller and recipient's handsets, as well as networks, have to support the feature. The LTE standard covers a range of many different bands, each of which is designated by both a frequency and a band number: As a result, phones from one country may not work in other countries. Users will need a multi-band capable phone for roaming internationally. According to the European Telecommunications Standards Institute 's (ETSI) intellectual property rights (IPR) database, about 50 companies have declared, as of March 2012, holding essential patents covering

As of March 2013, 156 commercial 4G LTE networks existed, including 142 LTE-FDD networks and 14 LTE-TDD networks. As of November 2013, the South Korean government planned to allow a fourth wireless carrier in 2014, which would provide LTE-TDD services, and in December 2013, LTE-TDD licenses were granted to China's three mobile operators, allowing commercial deployment of 4G LTE services. In January 2014, Nokia Solutions and Networks indicated that it had completed
