DataTAC is a wireless data network technology originally developed 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 acquired by Lenovo in 2014.
RadioMail was introduced in 1992 to allow users to receive and send messages over the internet via a wireless data network known as Mobitex.
Velocita Wireless is a national wireless-telecommunications service provider that is based in Woodbridge, New Jersey, United States.
 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.
The Inter@ctive Pager, introduced in 1996 by Research In Motion (RIM), allowed users to receive and send messages over the internet via a wireless data network known as Mobitex.
 The US Operator of Mobitex, RAM Mobile Data operated the network and introduced the Inter@ctive Pager service as RAMfirst Interactive Paging.
 The product was named the 1997 Top Product by Wireless for the Corporate User Magazine.
 The Inter@ctive Pager was also known as the RIM-900.
Avionics Full-Duplex Switched Ethernet (AFDX) is a data network, patented by international aircraft manufacturer Airbus, for safety-critical applications that utilizes dedicated bandwidth while providing deterministic quality of service (QoS).
 AFDX is a registered trademark by Airbus in several countries worldwide, including Europe.
 The AFDX data network is based on Ethernet technology using commercial off-the-shelf (COTS) components.
 The AFDX data network is a specific implementation of ARINC Specification 664 Part 7, a profiled version of an IEEE 802.3 network per parts 1 & 2, which defines how commercial off-the-shelf networking components will be used for future generation Aircraft Data Networks (ADN).
 The six primary aspects of an AFDX data network include full duplex, redundancy, determinism, high speed performance, switched and profiled network.
pCell technology is a mobile wireless technology developed by Artemis Networks claimed to allow all equipped mobile devices within a pCell coverage area to each receive 100% of the available theoretical bandwidth capacity.
 This differs significantly from existing mobile wireless data technologies, such as 4G LTE, whereby the data throughput decreases as the number of active devices in the coverage area increases.
 The technology claims that it does not require increasing the amount of spectrum to increase the number of users served.
 It was originally under the name Distributed-input-Distributed-Output (DIDO).
Virtual Fiber is wireless data transmission comparable in data throughput to optic fiber.
 The term was coined in El Salvador, Central America to describe a communications network service provided by Five Nines Communications, S.A. de C.V. Wireless data transmission is used for mobile telephony, mobile internet service, monitoring, and security applications to name a few.
At the most basic level Personal Communications Service or PCS describes a set of wireless communications capabilities which allows some combination of terminal mobility, personal mobility, and service profile management.
 More specifically, PCS refers to any of several types of wireless voice and/or wireless data communications systems, typically incorporating digital technology, providing services similar to advanced cellular mobile or paging services.
 In addition, PCS can also be used to provide other wireless communications services, including services which allow people to place and receive communications while away from their home or office, as well as wireless communications to homes, office buildings and other fixed locations.
 Described in more commercial terms, PCS is a generation of wireless-phone technology that combines a range of features and services surpassing those available in analog- and digital-cellular phone systems, providing a user with an all-in-one wireless phone, paging, messaging, and data service.
BYOA or Bring-Your-Own-Access is an approach to wireless remote access to a company's network for mobile workers and home workers.
 With BYOA, end users are still obliged to form their own contract with a wireless network operator.
 The remote user's software may recognise mobile hardware, such as a wireless data card, in their computer, and set up a data session over a VPN or other remote access client, but end users are still exposed to the fact that their connectivity is built up from separate components.
