The Universal Mobile Telecommunications System (UMTS) is a 3G mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP, UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology. UMTS uses wideband code-division multiple access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators.
4G is the fourth generation of broadband cellular network technology, succeeding 3G and preceding 5G. A 4G system must provide capabilities defined by ITU in IMT Advanced. Potential and current applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing, and 3D television.
E-UTRA is the air interface of 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) upgrade path for mobile networks. It is an acronym for Evolved UMTS Terrestrial Radio Access, also known as the Evolved Universal Terrestrial Radio Access in early drafts of the 3GPP LTE specification. E-UTRAN is the combination of E-UTRA, user equipment (UE), and a Node B.
Sri Lanka Telecom PLC, doing business as SLT-MOBITEL, is the national telecommunications services provider in Sri Lanka and one of the country's largest companies with an annual turnover in excess of Rs 40 billion. The company provides domestic and corporate services which include fixed and wireless telephony, Internet access and IT services to domestic, public and business sector customers. As of 2018 SLT-MOBITEL was Sri Lanka's second largest mobile network operator with over 7.9 million subscribers.
High Speed Packet Access (HSPA) is an amalgamation of two mobile protocols—High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA)—that extends and improves the performance of existing 3G mobile telecommunication networks using the WCDMA protocols. A further-improved 3GPP standard called Evolved High Speed Packet Access was released late in 2008, with subsequent worldwide adoption beginning in 2010. The newer standard allows bit rates to reach as high as 337 Mbit/s in the downlink and 34 Mbit/s in the uplink; however, these speeds are rarely achieved in practice.
Evolved High Speed Packet Access, HSPA+, HSPA (Plus) or HSPAP, is a technical standard for wireless broadband telecommunication. It is the second phase of HSPA which has been introduced in 3GPP release 7 and being further improved in later 3GPP releases. HSPA+ can achieve data rates of up to 42.2 Mbit/s. It introduces antenna array technologies such as beamforming and multiple-input multiple-output communications (MIMO). Beamforming focuses the transmitted power of an antenna in a beam toward the user's direction. MIMO uses multiple antennas on the sending and receiving side. Further releases of the standard have introduced dual carrier operation, i.e. the simultaneous use of two 5 MHz carriers. HSPA+ is an evolution of HSPA that upgrades the existing 3G network and provides a method for telecom operators to migrate towards 4G speeds that are more comparable to the initially available speeds of newer LTE networks without deploying a new radio interface. HSPA+ should not be confused with LTE though, which uses an air interface based on orthogonal frequency-division modulation and multiple access.
bmobile is a Mobile Phone, Home Security provider, and fixed wireless provider of Trinidad and Tobago, operating as a division of TSTT.
LTE Advanced is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard. It was formally submitted as a candidate 4G to ITU-T in late 2009 as meeting the requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation Partnership Project (3GPP) in March 2011 as 3GPP Release 10.
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA standards. It improves on those standards' capacity and speed by using 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 XT Network was a brand name for a UMTS and LTE mobile network run by Spark New Zealand . The network was initially built nationwide on WCDMA/UMTS 850 MHz, with 2100 MHz infill in major urban areas. The UMTS network is HSPA+ enabled, with a maximum downlink transmission rate of 21.1 Mbit/s and an uplink rate of 5.2 Mbit/s attainable for capable hardware. HSPA+ has a theoretical maximum of 56 Mbit/s download speed and 22 Mbit/s upload speed. Then under Spark 4G LTE is being built out. The network is not 2G capable, Telecom never operated a public GSM network.
Qualcomm Gobi is a family of embedded mobile broadband modem products by Qualcomm. Gobi technology 2 was designed to allow for any product with the embedded solution to connect to the internet anywhere a wireless carrier provides data coverage. One of the more notable products that contain a Gobi modem is the iPhone 4 for Verizon, which contains a MDM6600, however it does not take advantage of the support for HSPA+.
Intel Mobile Communications (IMC), is the mobile research and development division of Intel. It was formed when Intel completed the acquisition of the Wireless Solutions (WLS) division of Infineon early in 2011 for US$1.4 billion. The Infineon subsidiary Comneon was also acquired by Intel and integrated into Intel Mobile Communications. IMC maintained offices in Munich from the Comneon deal under Intel Mobile Communications GmbH. Some other offices in Germany were closed in 2015.
The Samsung Exynos, formerly Hummingbird (Korean: 엑시노스), is a series of ARM-based system-on-chips developed by Samsung Electronics' System LSI division and manufactured by Samsung Foundry. It is a continuation of Samsung's earlier S3C, S5L and S5P line of SoCs.
Long-Term Evolution (LTE) telecommunications networks use several frequency bands with associated bandwidths.
The Asia-Pacific Telecommunity (APT) band plan is a type of segmentation of the 612–806 MHz band formalized by the APT in 2022–2023 and 2008-2010 respectively and specially configured for the deployment of mobile broadband technologies. This segmentation exists in two variants, FDD and TDD, that have been standardized by the 3rd Generation Partnership Project (3GPP) and recommended by the International Telecommunication Union (ITU) as segmentations A5 and A6, respectively. The APT band plan has been designed to enable the most efficient use of available spectrum. Therefore, this plan divides the band into contiguous blocks of frequencies that are as large as possible taking account of the need to avoid interference with services in other frequency bands. As the result, the TDD option includes 100 MHz of continuous spectrum, while the FDD option comprises two large blocks, one of 45 MHz for uplink transmission in the lower part of the band and the other also of 45 MHz for downlink transmission in the upper part. As defined in the standard, both FDD and TDD schemes for the 700 MHz band include guard bands of 5 MHz and 3 MHz at their lower and upper edges, respectively. The FDD version also includes a centre gap of 10 MHz. The guard bands serve the purpose of mitigating interference with adjacent bands while the FDD centre gap is required to avoid interference between uplink and downlink transmissions. The two arrangements are shown graphically in figures 1 and 2.

Frequency bands for 5G New Radio, which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), which includes sub-6 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to cover potential new spectrum offerings from 410 MHz to 7125 MHz. The other is Frequency Range 2 (FR2), which includes frequency bands from 24.25 GHz to 71.0 GHz. Frequency bands are also available for non-terrestrial networks (NTN) in both the sub-6 GHz and in the 17.3 GHz to 30 GHz ranges.
