1xRTT
CDMA2000 (also known as C2K or IMT Multi‑Carrier (IMT‑MC)) is a family of 3G mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites. It is developed by 3GPP2 as a backwards-compatible successor to second-generation cdmaOne (IS-95) set of standards and used especially in North America and South Korea. CDMA2000 compares to UMTS, a competing set of 3G standards, which is developed by 3GPP and used in Europe, Japan, China, and Singapore. The name CDMA2000 denotes a family of standards that represent the successive, evolutionary stages of the underlying technology. These are: *Voice: CDMA2000 1xRTT, 1X Advanced *Data: CDMA2000 1xEV-DO (Evolution-Data Optimized): Release 0, Revision A, Revision B, Ultra Mobile Broadband (UMB) All are approved radio interfaces for the ITU's IMT-2000. In the United States, ''CDMA2000'' is a registered trademark of the Telecommunications Industry Association (TIA-USA). 1X CDMA2000 1X (IS-2 ...

Cellular One
Cellular One is the trademarked brand name that licenses services (radio frequencies for telecommunications) used by several cellular service providers in the United States. The brand was sold to Trilogy Partners by AT&T in 2008 shortly after AT&T had completed its acquisition of Dobson Communications. Cellular One was originally the trade name of one of the first mobile telephone service providers. History In 1977, the American Radio Telephone Service and Motorola formed Cellular One to offer services to the Baltimore/Washington, D.C., area. Cellular service began in the Baltimore/DC area in December 1983. In July 1986, it was announced that Metromedia Inc. would sell its 55 percent stake in Cellular One to Southwestern Bell. Southwestern Bell later joined into a partnership with McCaw Communications and Vanguard Cellular Systems called Cellular One Group, which the companies stated would help create a unified cellular network. Cellular One Group was eventually opened to in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellcom (United States)
Cellcom (officially called ''New-Cell Inc. dba Cellcom'') is a regional wireless service provider based in De Pere, Wisconsin, with roots that date back to 1910.

Evolved HSPA
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). Beam forming focuses the transmitted power of an antenna in a beam towards the user's direction. MIMO uses multiple antennas at 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 n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big River Telephone
Big River Telephone Company, LLC is a full-service telecommunications company located in the Midwestern United States. Big River Telephone is classified as a competitive local exchange carrier (CLEC) and is a wholesale digital provider of voice over Internet Protocol (VoIP) services to the cable industry. History Big River Telephone began in 1984 as LDD, Inc. LDD was primarily a long distance telephone service provider until The Telecommunications Act of 1996 opened the communication market. After this, LDD started competing for local telephone service. In 2001, independent investors acquired the assets of LDD, Inc. The former LDD image was phased out and the company took a new look and approach to the telecommunication industry as Big River Telephone Company, LLC. Over the next several years, Big River Telephone acquired several small local Internet service providers, including one of the leading ISPs in the area, Clas.net. Big River also acquired Cascade.net in 2005 and Atp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AT&T Inc
AT&T Inc. is an American multinational telecommunications holding company headquartered at Whitacre Tower in Downtown Dallas, Texas. It is the world's largest telecommunications company by revenue and the third largest provider of mobile telephone services in the U.S. , AT&T was ranked 13th on the ''Fortune'' 500 rankings of the largest United States corporations, with revenues of $168.8 billion. During most of the 20th century, AT&T had a monopoly on phone service in the United States. The company began its history as the American District Telegraph Company, formed in St. Louis in 1878. After expanding services to Arkansas, Kansas, Oklahoma and Texas, through a series of mergers, it became Southwestern Bell Telephone Company in 1920, which was then a subsidiary of American Telephone and Telegraph Company. The latter was a successor of the original Bell Telephone Company founded by Alexander Graham Bell in 1877. The American Bell Telephone Company formed the American Teleph ...

5G NR
5G NR (New Radio) is a new radio access technology (RAT) developed by 3GPP for the 5G (fifth generation) mobile network. It was designed to be the global standard for the air interface of 5G networks. As with 4G (LTE), it is based on OFDM. The 3GPP specification 38 series provides the technical details behind 5G NR, the successor of LTE. The study of NR within 3GPP started in 2015, and the first specification was made available by the end of 2017. While the 3GPP standardization process was ongoing, the industry had already begun efforts to implement infrastructure compliant with the draft standard, with the first large-scale commercial launch of 5G NR having occurred in the end of 2018. Since 2019, many operators have deployed 5G NR networks and handset manufacturers have developed 5G NR enabled handsets. Frequency bands 5G NR uses frequency bands in two frequency ranges: # Frequency Range 1 (FR1), for bands within 410 MHz – 7125 MHz # Frequency Range 2 (FR2), for bands ...

Wi-Fi Calling
Voice over Wireless LAN (VoWLAN), also Voice over WiFi (VoWiFi), is the use of a wireless broadband network according to the IEEE 802.11 standards for the purpose of vocal conversation. In essence, it is Voice over IP (VoIP) over a Wi-Fi network. In most cases, the Wi-Fi network and voice components supporting the voice system are privately owned. VoWLAN can be conducted over any Internet accessible device, including a laptop, PDA or VoWLAN units which look and function like DECT and cellphones. Just like for IP-DECT, the VoWLAN's main advantages to consumers are cheaper local and international calls, free calls to other VoWLAN units and a simplified integrated billing of both phone and Internet service providers. Although VoWLAN and 3G have certain feature similarities, VoWLAN is different in the sense that it uses a wireless internet network (typically 802.11) rather than a cellular network. Both VoWLAN and 3G are used in different ways, although with a femtocell the two c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In September 2007, MetroPCS, Cricket Wireless's competing carrier at the time, annou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3GPP Long Term Evolution
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 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 is also called 3.95G and has been marketed as "4G LTE" and "Advanced 4G"; but it does not meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. The requirements were set forth by the ITU-R organisation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
