DataTAC is a wireless data network technology originally developed by Mobile Data International which was later acquired by Motorola and deployed in the United States as the ARDIS network. DataTAC was also marketed in the mid-1990s as MobileData by Telecom Australia,and is still used by Bell Mobility as a paging network in Canada. The first public open and mobile data network using MDI DataTAC was found in Hong Kong as Hutchison Mobile Data Limited (a subsidiary of Hutchison Telecom) where public end-to-end data services are provided for enterprises, FedEx, and consumer mobile information services were also offered called MobileQuotes with financial information, news, telebetting and stock data.
Motorola, Inc. was an American multinational telecommunications company founded on September 25, 1928, based in Schaumburg, Illinois. After having lost $4.3 billion from 2007 to 2009, the company was divided into two independent public companies, Motorola Mobility and Motorola Solutions on January 4, 2011. Motorola Solutions is generally considered to be the direct successor to Motorola, as the reorganization was structured with Motorola Mobility being spun off. Motorola Mobility was sold to Google in 2012, and acquired by Lenovo in 2014.
Bell Mobility Inc. is a Canadian LTE and HSPA+ based wireless provider and the division of Bell Canada which sells wireless services across Canada. Bell Mobility and its affiliates combined have 9.5 million subscribers as of the end of Q3 2018, making it Canada's second largest wireless carrier.
DataTAC is an open standard for point to point wireless data communications, similar to Mobitex. Like Mobitex, it is mainly used in vertical market applications. One of the early DataTAC devices was the Newton Messaging Card, a two-way pager connected to a PC card using the DataTAC network. The original BlackBerry devices, the RIM 850 and 857 also used the DataTAC network.
Mobitex is an OSI based open standard, national public access wireless packet-switched data network. Mobitex puts great emphasis on safety and reliability with its use by military, police, firefighters and ambulance services. It was developed in the beginning of the 1980s by the Swedish Televerket Radio. From 1988 the development took place in Eritel, a joint-venture between Ericsson and Televerket, later on as an Ericsson subsidiary. Mobitex became operational in Sweden in 1986.
A vertical market is a market in which vendors offer goods and services specific to an industry, trade, profession, or other group of customers with specialized needs. An example could be software that manages services in hotels—amenities solutions. It is distinguished from a horizontal market, in which vendors offer a non-specific, broad range of goods and services to a large group of customers with a wide range of needs, such as businesses as a whole, men, women, households, or, in the broadest horizontal market, everyone.
BlackBerry is a line of smartphones, tablets, and services originally designed and marketed by Canadian company BlackBerry Limited. These are currently designed, manufactured, and marketed by TCL Communication, BB Merah Putih, and Optiemus Infracom for the global, Indonesian, and South Asian markets (respectively) using the BlackBerry brand under license.
In North America, DataTAC is typically deployed in the 800 MHz band. DataTAC was also deployed in the same band by Telecom Australia (now Telstra).
Telstra Corporation Limited is Australia's largest telecommunications company which builds and operates telecommunications networks and markets voice, mobile, internet access, pay television and other products and services.
The DataTAC network runs at speeds up to 19.2 kbit/s, which is not sufficient to handle most of the wireless data applications available today. The network runs 25 kHz channels in the 800 MHz frequency bands. Due to the lower frequency bands that DataTAC uses, in-building coverage is typically better than with newer, higher frequency networks.
In the 1990s a DataTAC network operators group was put together by Motorola called Worldwide Wireless Data Networks Operators Group (WWDNOG) chaired by Shahram Mehraban, Motorola's DataTAC system product manager.
Advanced Mobile Phone System (AMPS) was an analog mobile phone system standard developed by Bell Labs, and officially introduced in the Americas on October 13, 1983, Israel in 1986, Australia in 1987, Singapore in 1988, and Pakistan in 1990. It was the primary analog mobile phone system in North America through the 1980s and into the 2000s. As of February 18, 2008, carriers in the United States were no longer required to support AMPS and companies such as AT&T and Verizon Communications have discontinued this service permanently. AMPS was discontinued in Australia in September 2000, in Pakistan by October 2004,, in Israel by January 2010, and Brazil by 2010.
GSM is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets. It was first deployed in Finland in December 1991. As of 2014, it has become the global standard for mobile communications – with over 90% market share, operating in over 193 countries and territories.
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, UMTS is a component of the International Telecommunications 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.
Integrated Digital Enhanced Network (iDEN) is a mobile telecommunications technology, developed by Motorola, which provides its users the benefits of a trunked radio and a cellular telephone. It was called the first mobile social network by many technology industry analysts. iDEN places more users in a given spectral space, compared to analog cellular and two-way radio systems, by using speech compression and time division multiple access (TDMA).
Wireless local loop (WLL), is the use of a wireless communications link as the "last mile / first mile" connection for delivering plain old telephone service (POTS) or Internet access to telecommunications customers. Various types of WLL systems and technologies exist.
3G, short for third generation, is the third generation of wireless mobile telecommunications technology. It is the upgrade for 2G and 2.5G GPRS networks, for faster internet speed. This is based on a set of standards used for mobile devices and mobile telecommunications use services and networks that comply with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the International Telecommunication Union. 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV.
WiMAX is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide multiple physical layer (PHY) and Media Access Control (MAC) options.
4G is the fourth generation of broadband cellular network technology, succeeding 3G. 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.
The 33-centimeter or 900 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio on a secondary basis. It ranges from 902 to 928 MHz and is unique to ITU Region 2. It is primarily used for very local communications as opposed to bands lower in frequency. However, very high antennas with high gain have shown 33 centimeters can provide good long range communications almost equal to systems on lower frequencies such as the 70 centimeter band. The band is also used by industrial, scientific, and medical (ISM) equipment, as well as low powered unlicensed devices. Amateur stations must accept harmful interference caused by ISM users but may receive protection from unlicensed devices.
GSM frequency bands or frequency ranges are the cellular frequencies designated by the ITU for the operation of GSM mobile phones and other mobile devices.
The history of mobile phones covers mobile communication devices that connect wirelessly to the public switched telephone network.
The Motorola Razr was a series of mobile phones by Motorola, part of the 4LTR line. The V3 was the first phone released in the series and was introduced in July 2004 and released in the market in the third quarter of 2004. The V3 model was followed soon thereafter by the much improved V3i with a collaboration with Apple Inc. for iTunes to be built-in.

Known by several names over the years, Velocita Wireless has been in existence for over 17 years as the operator of the Mobitex network in the United States. Previously known as Cingular Interactive, L.P., BellSouth Wireless Data and prior to that RAM Mobile Data, Velocita Wireless carved a market for itself with the acquisition of the Mobitex network from Cingular and rebranding itself overall as Velocita in 2004.
In telecommunication, 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 technologies. It increases the capacity and speed using a different radio interface together with core network improvements. The standard is developed by the 3GPP and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. The different LTE frequencies and bands used in different countries mean that only multi-band phones are able to use LTE in all countries where it is supported.
Vodafone Australia or Vodafone Hutchison Australia (VHA) is a mobile telecommunications company and Internet service provider that operates the Vodafone brand in Australia. The result of a 2009 merger between Vodafone Australia and Hutchison 3G Australia, it is Australia's third-largest mobile carrier with approximately 5.8 million subscribers, A$3.5 billion in annual revenue and a 19 per cent market share making it Australia's third largest mobile telecommunications provider behind Telstra and Optus. It also offers fixed-line and wire broadband services via the National Broadband Network.
Cellular frequencies are the sets of frequency ranges within the ultra high frequency band that have been assigned for cellular-compatible mobile devices, such as mobile phones, to connect to cellular networks. Most mobile networks worldwide use portions of the radio frequency spectrum, allocated to the mobile service, for the transmission and reception of their signals. The particular bands may also be shared with other radiocommunication services, e.g. broadcasting service, and fixed service operation.
