The Motorola Envoy Personal Wireless Communicator was a personal digital assistant initially slated for release by Motorola in summer 1994 but delayed and then available for public sale in February 1995. [1] [2] It was built to run General Magic's Magic CAP operating system, and it combined wireless, telephone, and infrared modems in a single PDA package. Andy Rubin led development of the Motorola Envoy. [3]
Personal digital assistants (i.e. PDA's) were electronic handheld organizers that were used in the 1990s to communicate via email, manage calendars, store contact information, and manage files. Examples of PDAs include the Newton MessagePad released by Apple Inc. in 1993 and the Palm Pilot released by Palm Inc. in 1996. The Motorola Envoy was a particularly notable PDA in view of its built-in wireless communication capability and its well-received user interface, thus referenced by some to be a predecessor of the modern day smartphone. [4]
The hardware of the Motorola Envoy included a Motorola Dragon I/68349 microprocessor, 4 MB of read only memory (ROM), 1 MB of random access memory (RAM), and an LCD display. Of particular interest were the wireless communications capabilities of the Envoy. Its built-in communication components included a radio modem capable of 4,800 bits per second communication, a fax and data modem, and an infrared transceiver capable of 38.4 kbit/s of data transfer. [5] [6] The Envoy also included a PCMCIA interface to expands its communications or other capabilities. The housing had dimensions of 3.5 cm (height) x 17.3 cm (width) x 14.4 cm (depth) and weighed about 0.77 kg. [7]
The Motorola Envoy was one of the first PDAs to operate the Magic CAP software, which made extensive use of the built-in wireless communications components of the device. The main screen of Magic CAP displayed a desktop having a phone icon, Rolodex icon, Postcard/writing instrument icon, notebook icon, and calendar book icon, thus simulating real-world productivity tools used by many people. [8] Similarly, a clock, an inbox, an outbox, and a filing cabinet were shown behind the desk, and a control bar provided access to other features of the device. Several of these tools provided simple access to communication features, such as text messaging and addresses, which are widely used by modern smartphones.
The Motorola Envoy provided a convenient way to utilize communication data without a wired connection but, ultimately, the Envoy was held back by its high cost of ownership. The Envoy device had a price tag of about $1500 at launch, and an early-adopter reported a bill for one month of usage of about $400 from the ARDIS network for data communication. [9] [10]
Motorola reused the name for at least one previous product. [11] [12] [13] It is also a UHF tone and vibrate paging receiver produced in the mid-1980s that responded to two-tone sequential encoding, including GE type 99, Quick Call II & 1+1, REACH* and 5-Tone Sequential.
Motorola, Inc. was an American multinational telecommunications company based in Schaumburg, Illinois. It was founded in 1928 as Galvin Manufacturing Corporation by brothers Paul and Joseph Galvin. The company changed its name to Motorola in 1947. After having lost $4.3 billion from 2007 to 2009, Motorola was split into two independent public companies, Motorola Mobility and Motorola Solutions, on January 4, 2011. The reorganization was structured with Motorola Solutions legally succeeding Motorola, Inc., and Motorola Mobility being spun off.
A personal area network (PAN) is a computer network for interconnecting electronic devices within an individual person's workspace. A PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the personal devices themselves, or for connecting to a higher level network and the Internet where one master device takes up the role as gateway.
The Infrared Data Association (IrDA) is an industry-driven interest group that was founded in 1994 by around 50 companies. IrDA provides specifications for a complete set of protocols for wireless infrared communications, and the name "IrDA" also refers to that set of protocols. The main reason for using the IrDA protocols had been wireless data transfer over the "last one meter" using point-and-shoot principles. Thus, it has been implemented in portable devices such as mobile telephones, laptops, cameras, printers, and medical devices. The main characteristics of this kind of wireless optical communication are physically secure data transfer, line-of-sight (LOS) and very low bit error rate (BER) that makes it very efficient.
Wireless communication is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phenomena, such as light and magnetic or electric fields, or the use of sound.
A pager, also known as a beeper or bleeper, is a wireless telecommunications device that receives and displays alphanumeric or voice messages. One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to, and originate messages using an internal transmitter. In Japanese, it was commonly called a pocket bell or pokeberu (ポケベル), which is an example of wasei-eigo.
Mobile computing is human–computer interaction in which a computer is expected to be transported during normal usage and allow for transmission of data, which can include voice and video transmissions. Mobile computing involves mobile communication, mobile hardware, and mobile software. Communication issues include ad hoc networks and infrastructure networks as well as communication properties, protocols, data formats, and concrete technologies. Hardware includes mobile devices or device components. Mobile software deals with the characteristics and requirements of mobile applications.
A mobile device, also referred to as a digital assistant, is a computer small enough to hold and operate in the hand. Mobile devices typically have a flat LCD or OLED screen, a touchscreen interface, and digital or physical buttons. They may also have a physical keyboard. Many mobile devices can connect to the Internet and connect with other devices, such as car entertainment systems or headsets, via Wi-Fi, Bluetooth, cellular networks, or near-field communication. Integrated cameras, the ability to place and receive voice and video telephone calls, video games, and Global Positioning System (GPS) capabilities are common. Power is typically provided by a lithium-ion battery. Mobile devices may run mobile operating systems that allow third-party applications to be installed and run.
In the United States, the Multi-Use Radio Service (MURS) is a licensed by rule two-way radio service similar to the Citizens band (CB). Established by the U.S. Federal Communications Commission in the fall of 2000, MURS created a radio service allowing for licensed by rule operation in a narrow selection of the VHF band, with a power limit of 2 watts. The FCC formally defines MURS as "a private, two-way, short-distance voice or data communications service for personal or business activities of the general public." MURS stations may not be connected to the public telephone network, may not be used for store and forward operations, and radio repeaters are not permitted.
The history of mobile phones covers mobile communication devices that connect wirelessly to the public switched telephone network.
General Magic was an American software and electronics company co-founded by Bill Atkinson, Andy Hertzfeld, and Marc Porat. Based in Mountain View, California, the company developed precursors to "USB, software modems, small touchscreens, touchscreen controller ICs, ASICs, multimedia email, networked games, streaming TV, and early e-commerce notions." General Magic's main product was Magic Cap, the operating system used in 1994 by the Motorola Envoy and Sony's Magic Link PDA. It also introduced the programming language Telescript. After announcing it would cease operations in 2002, it was liquidated in 2004 with Paul Allen purchasing most of its patents.
Magic Cap is a discontinued object-oriented operating system for PDAs developed by General Magic. Tony Fadell was a contributor to the platform, and Darin Adler was an architect.
The IBM Simon Personal Communicator is a handheld, touchscreen PDA designed by International Business Machines (IBM), and manufactured by Mitsubishi Electric. Although the term "smartphone" was not coined until 1995, because of Simon's features and capabilities, it has been retrospectively referred to as the first true smartphone.
The term personal communicator has been used with several meanings. Around 1990 the next generation digital mobile phones were called digital personal communicators. Another definition, coined in 1991, is for a category of handheld devices that provide personal information manager functions and packet switched wireless data communications capabilities over wireless wide area networks such as cellular networks. These devices are now commonly referred to as smartphones.
Mobile broadband is the marketing term for wireless Internet access via mobile networks. Access to the network can be made through a portable modem, wireless modem, or a tablet/smartphone or other mobile device. The first wireless Internet access became available in 1991 as part of the second generation (2G) of mobile phone technology. Higher speeds became available in 2001 and 2006 as part of the third (3G) and fourth (4G) generations. In 2011, 90% of the world's population lived in areas with 2G coverage, while 45% lived in areas with 2G and 3G coverage. Mobile broadband uses the spectrum of 225 MHz to 3700 MHz.
Xircom, Inc., was an American computer networking hardware and mobile technology company. Headquartered in Thousand Oaks, California, Xircom was one of the first companies to develop network computing products for notebook computers. Products included computer memory cards, LAN adapters, modems, and remote access server products. The company's products enabled notebook users to share information over a network connection.
Underwater acoustic communication is a technique of sending and receiving messages in water. There are several ways of employing such communication but the most common is by using hydrophones. Underwater communication is difficult due to factors such as multi-path propagation, time variations of the channel, small available bandwidth and strong signal attenuation, especially over long ranges. Compared to terrestrial communication, underwater communication has low data rates because it uses acoustic waves instead of electromagnetic waves.
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.
Digital Ocean, Inc., was founded in 1992 by Jeffery Alhom. Digital Ocean was a maker of wireless products from 1992 until it was disbanded in 1998.
