The Motorola bag phone is the colloquial name for a line of personal transportable cellular telephones manufactured by Motorola, inc. from 1988 to 2000.
Motorola introduced the Bag Phone line in 1988. [1] These phones offered more durability and higher power output (up to 3 watts) than more conventional cell phones of the time, such as Motorola's own DynaTAC and MicroTAC handheld phones, making them popular for truckers, boaters, and people in rural areas. Because of their durability, many examples of these phones are still in working order today.
The Bag Phones are a derivative of the Motorola Tough Talker series of transportable phones, which in turn descended from the DynaTAC car phones introduced in 1984. All of these phones feature a modular design in which the handset attaches to the transceiver, which is then powered by either a vehicle's power system (in the car phones) or a battery pack (in the transportables). By reducing the size and weight of the transceiver and battery pack, and introducing more fashionable bags (originally nylon on the earliest models, but changed to leather in about 1990 or so) in which to contain them, Motorola was able to make them more marketable to the average cellular phone consumer, and hence the Bag Phone.
The handset consists of a digital numeric or alphanumeric display with Pwr (indicating the phone is turned on; indicated by a dot in some models), InUse (indicating that a call is in progress), NoSvc (cannot receive a cellular signal and is unable to make or receive calls), and Roam (accessing a cellular system other than your home system) indicators, a numeric keypad with other buttons for different functions (depending on the model), and a loudspeaker for the ringer and hands-free use. This plugs into the transceiver, which also houses connections for a removable "rubber duck" antenna, and the power supply header which plugs into a 12 volt automotive outlet and an optional 12 volt sealed lead-acid battery. The battery provides up to 2.5 hours of talk time and 48 hours of standby time. All of these parts are put together in a specially designed bag made by either Caseworks, Inc. of Chicago, Illinois, or Service Manufacturing Corporation of Aurora, Illinois. These phones can also be permanently installed in a car. The only Bag Phone to deviate from this architecture was the Power PAK, which placed the controls and display on the transceiver and used an LED display similar to that used in some DynaTAC and MicroTAC phones.
The majority of Bag Phones operated on the AMPS network, and a few special models produced in the late 1990s, dubbed the Digital Concert Series, ran on the TDMA network, in addition to AMPS. Because both the AMPS and TDMA networks are extinct as of February 2008, [2] the service life of all Motorola Bag Phones have come to end, and they now serve only as a collector's item.
The original Motorola Bag Phone has been succeeded by the Motorola M800 and M900 Bag Phones, introduced in 2005. While they are technologically dissimilar to the original Bag Phones and use an entirely different user interface, the M800 and M900 support CDMA and GSM, respectively, and add the basic features of modern cell phones. Additionally, they are backwards compatible with batteries for the original Bag Phones.
Although they are technically all similar, Motorola produced many different models of the bag phone, differing in features and display type. These can be determined by the model number on the underside of the handset, beginning with SCN (TLN on early models). Each type of handset also had its own transceiver, marked with a model number beginning with SUN. Random handsets can be used with random transceivers, but some mismatches may result in unusable functions. For example, plugging a 4500 handset into a 3 Button transceiver will result in the Up/Down, one-touch, VOL and STO buttons to be either unusable or perform a totally different function. Some transceivers will detect a mismatched handset, and display "LOANER" upon power-up.
Most handsets utilized a monochrome LCD display capable of displaying 7 or 10 digits, with green or orange LED backlighting. The better featured handsets used a 7 digit alphanumeric display, and offered a color LCD display as an option.
The color LCD display utilized the colors orange for the alphanumeric display area (red on the Digital Concert Series), green for the power and InUse indicators, red for the NoSvc indicator, and yellow for the Roam indicator. While the color display was more attractive, it has a few downsides. An incandescent lamp is used for backlighting, which not only draws more power, thus reducing battery life in a portable application, but has a definite lifespan. In addition, the display can be hard to read in sunlight, and when the backlight extinguishes during battery operated use, the indicators become nearly invisible.
The America Series 820 and Power PAK bag phone models used an LED display.
The Motorola Bag Phone was sold in several types of carry cases ("bags"), with each model being available with one or two types. The earliest bag phones, which used a large transceiver similar to that used in the Tough Talker transportable phone, came in a large upright case, in which the transceiver and battery (if applicable) sat in the bottom of the case, with the handset and hang-up cup assembly placed on top. Later bag phones were available in a smaller upright case, which also contained a side pocket where the battery could be placed.
Other cases available included the Soft-PAK, which houses the transceiver and battery in a large pocket beside the handset, and the Attaché Carry Case, which in addition to a setup similar to the Soft-PAK, contains several pockets for accessories such as a pen, day planner, and the phone's included documentation. [3]
The Dynasty, Meteor, Pulsar, Ambassador II, and America Series AMS833 phones were all available in a unique case which contained a setup similar to the Soft-PAK, and a single pocket on the exterior of the case, and the name of the phone stitched into the case. The Power PAK phone came in a unique case similar to the Soft-PAK, with an external zippered pocket in which to contain the battery.

Advanced Mobile Phone System (AMPS) was an analog mobile phone system standard originally developed by Bell Labs and later modified in a cooperative effort between Bell Labs and Motorola. It was officially introduced in the Americas on October 13, 1983, and was deployed in many other countries too, including 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.
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome. LCDs are available to display arbitrary images or fixed images with low information content, which can be displayed or hidden. For instance: preset words, digits, and seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the color of the backlight, and a character negative LCD will have a black background with the letters being of the same color as the backlight. Optical filters are added to white on blue LCDs to give them their characteristic appearance.
Motorola, Inc. was an American multinational telecommunications company based in Schaumburg, Illinois, United States. After having lost $4.3 billion from 2007 to 2009, the company split 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, Inc., as the reorganization was structured with Motorola Mobility being spun off. Motorola Mobility was acquired by Lenovo in 2014.
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from Greek: τῆλε and φωνή, together meaning distant voice. A common short form of the term is phone, which came into use almost immediately after the first patent was issued.
A backlight is a form of illumination used in liquid crystal displays (LCDs). As LCDs do not produce light by themselves—unlike, for example, cathode ray tube (CRT), plasma (PDP) or OLED displays—they need illumination to produce a visible image. Backlights illuminate the LCD from the side or back of the display panel, unlike frontlights, which are placed in front of the LCD. Backlights are used in small displays to increase readability in low light conditions such as in wristwatches, and are used in smart phones, computer displays and LCD televisions to produce light in a manner similar to a CRT display. A review of some early backlighting schemes for LCDs is given in a report Engineering and Technology History by Peter J. Wild.

DynaTAC is a series of cellular telephones manufactured by Motorola, Inc. from 1983 to 1994. The Motorola DynaTAC 8000X commercial portable cellular phone received approval from the U.S. FCC on September 21, 1983. A full charge took roughly 10 hours, and it offered 30 minutes of talk time. It also offered an LED display for dialing or recall of one of 30 phone numbers. It was priced at $3,995 in 1984, its commercial release year, equivalent to $10,420 in 2021. DynaTAC was an abbreviation of "Dynamic Adaptive Total Area Coverage".
The Motorola Razr is a series of mobile phones by Motorola, part of the 4LTR line. The V3 was the first phone shown in the series and was introduced in December 2003 and released in the market in the third quarter of 2004. The V3 model was followed soon thereafter by the improved V3i, including a collaboration with Apple Inc. for iTunes to be built-in. It was launched in 2006.
The Motorola International 3200 was the first digital hand-held mobile telephone introduced in 1992, along with the more compact 5200, 5080, 7200 and 7500 "flip phones" introduced in 1994. It was preceded by the International 1000 and 2000 GSM phones, quite big, and although being the first GSM portable phones, they were not GSM certified, therefore couldn't be officially connected to the network.
The Motorola StarTAC, first released on January 3, 1996, is often assumed to be the first ever clamshell (flip) mobile phone. Technically, however, NEC had been releasing flip phones on NTT Docomo's PDC Mova network long before 1996, namely the TZ-804 and TZ-1501, both respectively launched in 1991 and late 1994. Another early precursor of this form factor was the Grillo, which was designed in Italy by Richard Sapper and Marco Zanuso in 1965. The StarTAC is the successor of the MicroTAC, a semi-clamshell design first launched in 1989. Whereas the MicroTAC's flip folded down from below the keypad, the StarTAC folded up from above the display. In 2005, PC World named the StarTAC as the 6th Greatest Gadget of the Past 50 Years. The StarTAC was among the first mobile phones to gain widespread consumer adoption; approximately 60 million StarTACs were sold.

The Nokia 5110 is a GSM mobile phone that was introduced by Nokia on 12 April 1998.
The Motorola Fone was a candybar mobile phone from Motorola, one of a series of phones in the 4LTR line. It was the first mobile phone to use an electronic paper display.
The Nokia 1110 and Nokia 1110i are low-end GSM mobile phones sold by Nokia. The 1110 was released in 2005; the 1110i was released in 2006. Both are aimed at first-time mobile phone users. In Nokia's view, the 1110i has the advantage of ease-of-use, reliability and a low price. These phones are very similar to the Nokia 1100. Between January and May 2007, the 1110 was sold by Nokia as their basic low-end monochrome model, before being superseded by the Nokia 1200. One of its key markets is that of developing countries.
The Motorola MicroTAC is a cellular phone first manufactured as an analog version in 1989. GSM-compatible and TDMA/Dual-Mode versions were introduced in 1994. The MicroTAC introduced a new "flip" design, where the "mouthpiece" folded over the keypad, although on later production the "mouthpiece" was actually located in the base of the phone, along with the ringer. This set the standard and became the model for modern flip phones today. Its predecessor was the much larger Motorola DynaTAC and it was succeeded by the Motorola StarTAC in 1996. "TAC" was an abbreviation of "Total Area Coverage" in all three models.
PenTile matrix is a family of patented subpixel matrix schemes used in electronic device displays. PenTile is a trademark of Samsung. PenTile matrices are used in AMOLED and LCD displays.
The Motorola i920/i930 is Motorola's first wave of iDEN Protocol-based smartphones.
Always on display is a smartphone feature that has the device continue to show limited information while the phone is asleep. It is widely available on Android handsets, and is available on Apple iPhones since the iPhone 14 Pro. On some Android devices, the feature is sometimes called Ambient Display or Active Display, depending on its implementation and behavior. Depending on the phone's design, it may be a replacement or complementary to another feature, such as the notification LED.
The Nokia 101 is an analogue mobile phone from Nokia released in 1992 that have variants for the NMT, AMPS and ETACS cellular networks. The 101 is considered to have been a significant handset for Nokia, one that started the company's major success in the market that decade. It was the first model in the new 3-digit naming strategy for analogue handsets.
