MAC - Media Access Control; the lower sublayer of the OSI system
MAD - Memory Analog Digital
MAN - Metropolitan Area Network
MAP - Mobile Application Part
Mb- Megabite
( a unit of data transmission speed equal to one million bits per second)
MCC - Mobile Country Code
MCU - Micro Control Unit
MCPA - Multi Carrier Power Amplifier
MeXe - Mobile Execution Environment
(likely to be based on Java, MeXe enables WAP-enabled devices to offer a wider range of features with greater security and flexibility, as well as greater control of telephony features)
MFSK - Multiple Frequency Shift Keying
MHz - Megahertz (a unit of frequency equal to one million Hertz)
MMI - Man Machine Interface
MMS - Multimedia Messaging Service
(an evolution of SMS, MMS goes beyond text messaging offering various kinds of multimedia content including images, audio and video clips)
MMSK - Modified Minimum Shift Keying
MNC - Mobile Network Code
MNO - Mobile Network Operator
Modulation:
The process of imposing an information signal on a carrier. This can be done by changing the amplitude (AM), the frequency (FM) or the phase, or any combination of these
MPEG:
Motion Picture Experts Group; MPEG4 is a technology for compressing voice and video so that the information can be transmitted over normally difficult links such as mobile radio
MS - Mobile Station
MSC - Mobile Switching Centre
(the switching centre of a mobile phone network, the MSC has interfaces to the BSCs, HLR, VLR and other MSCs)
MSIN - Mobile Station Identification Number
MSISDN - Mobile Station International ISDN Number
MSK - Minimum Shift Keying (Another term for FFSK)
Multiplexing:
A telecommunications technique where several channels can be combined to share the same transmission medium. The most common forms are Time Division Multiplexing (TDM) and Frequency Division Multiplexing (FDM)
MVPN - Mobile Virtual Private Network
Master Reset:
restores the setting to factory
MIDI - Musical Instrument Digital Interface
(a standard that allows digital musical instruments to communicate with one another. In cell phone terms, MIDI is what gives you polyphonic sounds; which means your ring tones can sound like real music instead of beeps. )
MMS - Multimedia Messaging Service
(a further extension of SMS and EMS.MMS is designed to make use of newer and quicker mobile transmission methods such as GPRS, HSCSD, EDGE and UMTS, involving the attachment of multimedia extensions to messages, such as video and sound. An e-mail function is also planned. )
MO-SMS - Mobile-Originated Short Message Service
(the ability to send short text messages from a phone. Both the phone and the carrier’s network must support this feature for it to work. Messages can be sent to other phones by phone number. Many phones also allow sending messages directly to e-mail addresses. )
