MMode
mMode was the brand name for the wireless data service offered by the former AT&T Wireless. Based on NTT DoCoMo's i-mode, it was available to any AT&T Wireless subscriber with a WAP-capable phone. Operating over GPRS, EDGE, and UMTS, mMode was the successor to AT&T's unsuccessful CDPD-based Pocketnet. Although it was no longer available to new subscribers since the Cingular takeover, legacy AT&T Wireless subscribers were able to access the system until June 2010.

AT&T Wireless Services
AT&T Wireless Services, formerly part of AT&T Corp., was a wireless telephone carrier founded in 1987 in the United States, based in Redmond, Washington, and later traded on the New York Stock Exchange under the stock symbol "AWE", as a separate entity from its former parent. On October 26, 2004, AT&T Wireless was acquired by ''Cingular Wireless'', a joint venture of SBC Communications and BellSouth, to form the largest wireless carrier in the United States at the time. On November 16, 2004, AT&T Wireless stores were rechristened under the Cingular banner. The legal entity "AT&T Wireless Services, Inc." was renamed "New Cingular Wireless Services, Inc." In late 2005, SBC (the majority partner in Cingular) acquired the original AT&T, and rebranded as "the new AT&T". Cingular became wholly owned by the new AT&T in December 2006 as a result of the new AT&T's acquisition of BellSouth. After the merger, Cingular was renamed AT&T Mobility in late 2006 and remained the largest wirel ...

I-mode
NTT DoCoMo's i-mode is a mobile internet (distinct from wireless internet) service popular in Japan. Unlike Wireless Application Protocols, i-mode encompasses a wider variety of internet standards, including web access, e-mail, and the packet-switched network that delivers the data. i-mode users also have access to other various services such as: sports results, weather forecasts, games, financial services, and ticket booking. Content is provided by specialised services, typically from the mobile carrier, which allows them to have tighter control over billing. Like WAP, i-mode delivers only those services that are specifically converted for the service, or are converted through gateways. Description In contrast with the Wireless Application Protocol (WAP) standard, which used Wireless Markup Language (WML) on top of a protocol stack for wireless handheld devices, i-mode borrows from DoCoMo proprietary protocols ALP (HTTP) and TLP ( TCP, UDP), as well as fixed Internet data ...

Wireless Application Protocol
Wireless Application Protocol (WAP) is a technical standard for accessing information over a mobile wireless network. A WAP browser is a web browser for mobile devices such as mobile phones that use the protocol. Introduced in 1999, WAP achieved some popularity in the early 2000s, but by the 2010s it had been largely superseded by more modern standards. Almost all modern handset internet browsers now fully support HTML, so they do not need to use WAP markup for web page compatibility, and therefore, most are no longer able to render and display pages written in WML, WAP's markup language. Before the introduction of WAP, mobile service providers had limited opportunities to offer interactive data services, but needed interactivity to support Internet and Web applications such as email, stock prices, news and sports headlines. The Japanese i-mode system offered another major competing wireless data protocol. Technical specifications WAP stack The WAP standard described a pr ...

GPRS
General Packet Radio Service (GPRS) is a packet oriented mobile data standard on the 2G and 3G cellular communication network's global system for mobile communications (GSM). GPRS was established by European Telecommunications Standards Institute (ETSI) in response to the earlier CDPD and i-mode packet-switched cellular technologies. It is now maintained by the 3rd Generation Partnership Project (3GPP). GPRS is typically sold according to the total volume of data transferred during the billing cycle, in contrast with circuit switched data, which is usually billed per minute of connection time, or sometimes by one-third minute increments. Usage above the GPRS bundled data cap may be charged per MB of data, speed limited, or disallowed. GPRS is a best-effort service, implying variable throughput and latency that depend on the number of other users sharing the service concurrently, as opposed to circuit switching, where a certain quality of service (QoS) is guaranteed durin ...

UMTS
The Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP (3rd Generation Partnership Project), 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. UMTS specifies a complete network system, which includes the radio access network (UMTS Terrestrial Radio Access Network, or UTRAN), the core network (Mobile Application Part, or MAP) and the authentication of users via SIM (subscriber identity module) cards. The technology described in UMTS is sometimes also referred to as Freedom of Mobile Multimedia Access (FOMA) or 3GSM. Unlike EDGE (IMT Single-Carrier, based on GSM) and ...

Cellular Digital Packet Data
Cellular Digital Packet Data (CDPD) was a wide-area mobile data service which used unused bandwidth normally used by Advanced Mobile Phone System (AMPS) mobile phones between 800 and 900 MHz to transfer data. Speeds up to 19.2 kbit/s were possible, though real world speeds seldom reached higher than 9.6 kbit/s. The service was discontinued in conjunction with the retirement of the parent AMPS service; it has been functionally replaced by faster services such as 1xRTT, Evolution-Data Optimized, and UMTS/High Speed Packet Access (HSPA). Developed in the early 1990s, CDPD was large on the horizon as a future technology. However, it had difficulty competing against existing slower but less expensive Mobitex and DataTAC systems, and never quite gained widespread acceptance before newer, faster standards such as General Packet Radio Service (GPRS) became dominant. CDPD had very limited consumer products. AT&T Wireless first sold the technology in the United States under the Pocket ...
