MAC – Media Access Control
A MAC address is the unique hardware number that is hard coded on every Network Interface Card (
NIC) in the world. It is used in routing data
Packets through bridges and switches.
It is generally represented in one of these fashions: 00:e0:29:31:ab:65 or 00E02931AB65
A milliamperehour is 1000th of an ampere hour (Ah). Both measures are commonly used to describe the energy charge that a battery will hold and how long a device will run before the battery needs recharging.
Many batteries used for portable data collection computers use 1500mAh to 2700mAh batteries.
Mainframe is an industry term for a large computer, typically
manufactured by a large company such as IBM for the
commercial applications of Fortune 1000 businesses and
other large-scale computing purposes. Historically, a
mainframe is associated with centralized rather than
distributed computing. Today, IBM refers to its larger
processors as large serversand emphasizes that they can be
used to serve distributed users and smaller Servers in a
computing network.
MAN – Metropolitan Area Network
A MAN is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (
LAN) but smaller than the area covered by a wide area network
WAN).

Matrix 2 of 5 is a variable length numeric only Symbology used in various industrial application and mechanical numbering systems.
See Symbologies (List) for a list of common symbologies.
MaxiCodeis a fixed size matrix style Barcode Symbology which is made up of offset rows of hexagonal modules arranged around a unique bulls-eye finder pattern. Each MaxiCode symbol has 884 hexagonal modules arranged in 33 rows with each row containing up to 30 modules. The maximum data capacity for a MaxiCode symbol is 93 Alphanumeric characters or 138 Numeric characters.The symbology was designed by United Parcel Service for package tracking applications. The design of the MaxiCode symbology was chosen because it is well suited to high speed, orientation independent scanning. Although the capacity of a MaxiCode symbol is not as high as other matrix style bar code Symbologies, it was primarily designed to encode address data which rarely requires more than about 80 characters.
 |
MaxiCode symbols actually encode two separate messages - a Primary message and a Secondary message. The Primary message normally encodes a postal code, a 3 digit country code and a 3 digit class of service number. The Secondary message normally encodes address data and any other required information.
MCL from MCL Technologies, started off as a Symbol product and supported Symbol devices only. Recently, MCL broke away from Symbol and only very recently supports Intermec devices as well. MCL is a set of software tools that allow programmers and technical non-programmers and technical non-programmers to quickly and easily design, simulate, document, deploy, and run data collection applications for
Batch,
Wireless LAN and wireless
WAN implementations.
MCL-Designer is a
RAD tool. MCL-Net is a communication program for wireless or Ethernet exchange of files and/or data records between the host PC and data collection Terminal. MCL-Bridge is an interface to
SAP or to
Databases. MCL-Link communicates with mobile devices via a serial connection or by modem for remote access.
Media & Medium have multiple meanings in the AIDC industry.
- In Barcode printing, media refers to the ribbon and the labels used to print barcodes.
- In networking, media or transmission medium refers to the physical thing used to transmit data. Transmission mediums include various types of wire or cable such as twisted pair, coaxial and fiber, and Wireless mediums such as RF, Infrared, satellite and microwave.
Memory Effect is the tendency for a battery to “remember”its reduced capacity when the battery is used for less than its full capacity and then recharged. For example, a user uses his hand held data collection computer for only four hours, when its normal capacity is eight hours. He then puts the battery in the charger and repeats this process. When this practice is done over time, the battery will only provide a four hour capacity. A battery that is experiencing memory effect can usually be revived, if it hasn’t been permanently damaged, by fully discharging and recharging the battery several times.
MEMS (Micro-Electro Mechanical)
MEMS technology; a wafer based, small, fast and durable mechanical components are used in Intermec’s EL10 Laser engine MEMS technology; a wafer based, small, fast and durable mechanical components are used in Intermec’s EL10 laser engine. It uses no motor mirror, provides 500-4000 scans per second, consumes less power and is 1/66ththe size of a standard laser engine.
In the computer industry, middleware is a general term for any program or application that serves to "glue together" or mediate between two separate and often already existing programs. Typically, middleware programs provide messaging services so that different applications can communicate. The systematic tying together of disparate applications, often through the use of middleware, is known as enterprise application integration (EAI).
RFgen, Meteorand MCLare an excellent examples of middleware.
An international unit of measurement equal in one thousandth of an inch. Barcodes are measured using mils. Mil comes from the French word mille meaning thousand.
A barcode is measured by its narrowest bar. For example, this barcode has only two widths of bars, narrow and wide. The narrow bar measures 20 thousandths of an inch, or 20 mils. So, the barcode is said to be printed at 20 mils or it’s a 20 mil barcode.
Mobile Manager, from Wavelink, is a multi-vendor solution for providing effective network management and control over Wireless LANs. Mobile Manager will rapidly configure and deploy wireless networks (Access Points), maintain network health and performance, perform updates to mobile devices, and manage remote sites. This product is similar to but more Robust than Intermec’s MobileLAN Manager.
Mobile LAN Manager, from Intermec, is a Wireless network management software package that manages Intermec Access Points. It is a Java application, so it is a stand alone application (previous incarnations of this type of product from Intermec such as Inca View required that HP Open View be owned and installed by the customer.
This product is similar in nature to Mobile Manager from Wavelink, however it is not as robust as the Mobile Manager product.
Mobile LAN Manger has been discontinued by Intermec.
Modulation is the addition of information to or modification of a Carrier. A wide range of signals, such as light, sound, electronic pulses and radio, can be modulated. There are many types of modulation techniques including:
MRP – Materials Requirements Planning
In logistics, MRP is the process used to determine the amount of material to purchase and when to purchase it. Many MRP software packages are available.
A millisecond (ms or msec) is one thousandth of a second and is commonly used in measuring the time to read to or write from a hard diskor a CD-ROM player or to measure Packet travel time on a network.
MTBF – Mean Time Before Failure
MTBF is a measure of how reliable a hardware product or component is. For most components, the measure is typically in thousands or even tens of thousands of hours before a failure. For example, a hard disk drive may have a mean time before a failure of 300,000 hours. A desired MTBF can be used as a quantifiable objective when designing a new product. The MTBF figure can be developed as the result of intensive testing, based on actual product experience, or predicted by analyzing known factors. The manufacturer may provide it as an index of a product's or component's reliabilityand, in some cases, to give customers an idea of how much service to plan for.
a.k.a Multipath Distortion or Multipath Fading. Multipathing is the result of receiving an RF signal from multiple different paths at different times. This can lead to slow downs or even stoppages of RF networks.
In environments that contain metallic surfaces or products, multipathing can be very prominent. The use of diversity antennas can reduce the effects of multipathing.
Multiplexing is sending multiple signals or streams of information on a Carrier at the same time in the form of a single complex signal and then recovering (de-multiplexing) the separate signals at the receiving end. Hardware devices that perform this task are called multiplexers.
The types of signals that can be multiplexed included analog, digital, light, radio, etc.
The watt (abbreviated W) is the standard unit of power (or energy per unit time) and is the equivalent of one joule per second. The watt is used to specify the rate at which electrical energy is dissipated, or the rate at which electromagnetic energy is radiated, absorbed, or dissipated. mWor milliwattis one thousandth of a Watt. In
AC and
DC electrical cicuits, W and mW are used to specify wattage. In
RF, W and mW are also used to express output power.
